This is Vinny’s story.
How to sell a wastewater services business at the right time, to the right buyer, for the right price is the question Vincent “Vinny” Caruso had been turning over for almost two years before he picked up the phone. When the right time came, he called CGK Business Sales. Vinny ran a regional industrial and municipal wastewater services contractor headquartered out of Westminster, Colorado, in the Denver northwest metro corridor that runs through Wheat Ridge and Arvada and out toward Broomfield. The company did $8.4 million in annual revenue and roughly $1.7 million in EBITDA, with thirty-eight W-2 employees: Vinny plus a general manager, a dispatcher, fourteen CDL Class B tanker-endorsed vacuum truck operators, six PACP-certified CCTV inspection operators, four lift station service technicians, three industrial pretreatment cleanout crew leads, two grease trap pumping route drivers, two service van plumbers, four office and administration, and a single shared safety and compliance manager. Operations split across five core service lines: sewer cleaning and high-pressure jetting and CCTV inspection (28 percent of revenue, including line locating, condition assessment, and inflow-and-infiltration studies for municipal customers), lift station service and maintenance contracts (24 percent, including emergency lift station response), industrial pretreatment cleanout for food processors and breweries and metal-finishing plating shops along the I-70 industrial corridor (22 percent), grease trap pumping and grease-to-energy hauling for restaurants and institutional kitchens (16 percent), and trenchless rehabilitation work and miscellaneous repair (10 percent). Equipment fleet: twelve vacuum trucks, four high-pressure jetters, three CCTV inspection trucks with PACP-certified crews, two service vans. Customer base: five municipal contracts (City of Westminster, City of Arvada, City of Wheat Ridge, plus two special-district sanitation authorities) and roughly 250 private commercial accounts including the I-70 industrial corridor pretreatment customers and a route book of restaurants and institutional kitchens. He came to us in 2025 because he did not know who else to talk to about how to sell a wastewater services business at this size, with this fleet, with five municipal contracts under change-of-control review windows, and with a 26-year lead operator (Jorge Mendoza, the truck shop foreman and dispatch lead) who was ready to stay through the transition. This page is what happened next, and what could happen for you. Vinny is a composite, not a single real CGK seller, but the patterns and details are pulled from real wastewater services engagements.
The night before Vinny decided to sell a wastewater services business.
Most owners who decide to sell a wastewater services business have been carrying the question quietly for a year or two before they pick up the phone. Vinny was no different. He was 64. His father Salvatore had started the company in 1972 with one truck pumping grease traps for a handful of Italian-American family restaurants in north Denver and along Federal Boulevard, the kind of route work nobody else wanted. Vinny took over from his father in 1995 and spent the next thirty years building it into a regional industrial and municipal wastewater services contractor with a yard on the west side of Westminster, twelve vacuum trucks, four high-pressure jetters, three PACP-certified CCTV inspection trucks, two service vans, thirty-eight W-2 employees, and roughly 250 private commercial accounts plus the five municipal contracts (City of Westminster, City of Arvada, City of Wheat Ridge, and two special-district sanitation authorities) that gave the company a recurring revenue spine. The company did $8.4 million in annual revenue across the five service lines, roughly $1.7 million in EBITDA at the upper end of regional wastewater services norms (driven by the municipal contract diversification, the in-house PACP-certified CCTV bench, the recurring lift station maintenance roster, and a clean environmental compliance file going back fifteen years), and thirty-eight W-2 employees including Jorge Mendoza, the truck shop foreman and dispatch lead, who had been with the company for twenty-six years (Vinny had hired him in 1999 when Jorge first came up from Chihuahua, and Jorge had built every operating routine the yard ran on); a general manager Vinny had brought in from a Denver-area competitor in 2019; a dispatcher who routed the daily run sheets across the twelve vacuum trucks and the three CCTV inspection trucks; fourteen CDL Class B tanker-endorsed vacuum truck operators (CDL driver retention is the known industry pain point and Vinny had managed it through pay above market and a no-night-call policy on routine accounts); six PACP-certified CCTV inspection operators (the bench depth that lets the company self-perform municipal inflow-and-infiltration studies and condition assessments in-house instead of subcontracting); four lift station service technicians who carried the lift station service and emergency response phone; three industrial pretreatment cleanout crew leads who handled the food processors and breweries and metal-finishing plating shops along the I-70 industrial corridor; two grease trap pumping route drivers who ran the restaurant and institutional kitchen route; two service van plumbers who handled the trenchless and miscellaneous repair work; four office and administration; and a single shared safety and compliance manager who carried the OSHA confined-space-entry program, the DOT compliance file, and the NPDES discharge documentation across the company.
Why owners decide to sell a wastewater services business
The Friday Vinny finally submitted the form, his wife Maria had been at the kitchen table reading him the printed search results from her tablet. Maria was sixty-two, a retired Adams County school district administrator, the daughter of an Italian-American family that had been in north Denver since the early 1900s when the original sugar beet and railroad migration brought a generation of Italians and Mexicans into the same neighborhoods around Globeville and Swansea, and she had been the steady voice across thirty years of contracts and trucks and on-call rotations. Their son Anthony was 34, a commercial real estate developer in Boulder, and had told Vinny politely but firmly five years earlier that he was not coming back to run the trucks. Their daughter Gianna was 31, a sustainability consultant in Portland, and had not pretended she would. Vinny had three grandchildren in nearby Lakewood (Anthony’s two boys and Gianna’s daughter, who was visiting from Portland one or two weeks every quarter), and he had spent most of the past two years thinking about how he wanted to be the grandfather they actually saw on weekday mornings rather than the one who only made it to the Saturday games when the lift station phone was quiet. He had a lower-back surgery in mid-2024 that had taken him out of the yard for almost three months and reset what he thought he could keep doing on the trucks, and he had come back from the surgery with a clearer sense that he wanted to sell a wastewater services business while the company was still running well rather than wait until he had to. Jorge had been at the yard for twenty-six years and was committed to staying on post-close if the buyer ran the company in a way that kept the truck shop together. The general manager had been with Vinny for six years and was ready to keep operating. The dispatcher and the four office staff and the safety and compliance manager were settled. Vinny had been approached eleven times in the prior eighteen months: five times by PE-backed water and environmental services consolidators headquartered out of Houston and Atlanta and the Mid-Atlantic and a few national platforms, three times by regional wastewater services aggregators expanding their Front Range and intermountain footprint, twice by vertically-integrated waste hauling companies looking to add a wastewater services arm, and once by a trenchless rehabilitation platform interested in the CCTV bench as an entry point into Denver. Vinny did not know what the company was actually worth at $8.4 million revenue and $1.7 million EBITDA, with the twelve-truck vacuum fleet, the PACP-certified CCTV bench, the five municipal contracts, the I-70 industrial pretreatment book, and a fifteen-year clean environmental compliance file. He did not know whether the firms calling him were the right buyers for Jorge, for the fourteen CDL drivers, for the six PACP-certified inspectors, or for the lift station service technicians who carried the after-hours emergency response phone. He did not know whether the environmental tail risk window the buyers kept asking about was a normal diligence theme or a signal he needed to clean up something before going to market. He did not have a single peer in his life who had ever sold a wastewater services business at this size, with this municipal exposure, with this fleet, with this environmental compliance profile.
That is the night he found CGK and submitted the form. We called him back at 7:38 the next morning, while Vinny was at the Westminster yard watching Jorge sign out the first three vacuum trucks for the morning run.
The first call about how to sell a wastewater services business.
The first call was 58 minutes. We did most of the listening.
Owners who think about how to sell a wastewater services business in their early sixties, like Vinny, usually carry the same handful of pressures into the first call. Vinny talked about Jorge Mendoza and the way Jorge had been the actual operator of the truck shop and the dispatch routine since the early 2000s. He talked about the general manager he had brought in from a Denver-area competitor in 2019 and the way the GM ran the bid-and-quote work for the municipal contracts. He talked about the fourteen CDL Class B tanker-endorsed vacuum truck operators and the way pay above market and a no-night-call policy on routine accounts had let him keep his driver bench when the regional competitors were chronically short. He talked about the six PACP-certified CCTV inspection operators and the way the in-house bench was what let the company self-perform municipal inflow-and-infiltration studies and condition assessments in-house. He talked about the four lift station service technicians who carried the after-hours emergency response phone on a four-week rotation. He talked about the three industrial pretreatment cleanout crew leads who covered the food processors and breweries and metal-finishing plating shops along the I-70 industrial corridor. He talked about the two grease trap pumping route drivers who ran the restaurant and institutional kitchen route his father Salvatore had started in 1972. He talked about the City of Westminster contract that had been first awarded in 2003 and renewed every three to five years since, the City of Arvada and City of Wheat Ridge contracts that were on similar staggered renewal cycles, and the two special-district sanitation authority contracts that had come on more recently. He talked about the OSHA confined-space-entry program for lift stations and manhole and wet well work, the DOT compliance file on the hazmat hauling, the NPDES discharge documentation he had kept clean for fifteen years, and the safety and compliance manager who had carried that file with him. He talked about the three grandchildren in Lakewood and the two-year-old back surgery and Maria sitting at the kitchen table reading him the search results. He talked about Anthony in Boulder and Gianna in Portland and the way that had finally settled the succession question. We asked about the company the way you would ask if you were trying to understand it, not the way you would ask if you were trying to win the engagement. What we were listening for was not just the financials. We were listening for whether Vinny was actually ready to sell, what he was working toward, and whether his expectations on price were grounded in what the wastewater services M&A market would actually support.
At the end of that call, we set up a working session: an in-person conversation where one of our Managing Directors would walk Vinny through our valuation model and tell him honestly what his wastewater services business was likely to command. We did not promise him a written report. Written valuations involve substantially more work, and we charge for those when a seller actually needs one for partnership buyout, estate planning, a divorce, or another documentary purpose. The walkthrough was free because Vinny was clearly thinking seriously about how to sell a wastewater services business, the way someone thinks about it before they actually do it. Whether that ends up being in a year, five years, or longer, we make the same call.
The valuation session was the following Tuesday at 6:30 a.m. at the Westminster yard, before the first run sheet went out the truck shop door and after Jorge had finished the morning equipment walk-through across the vacuum and jetter fleet.
Vinny was not ready to sell a wastewater services business yet. He went home and waited five months.
The valuation session showed Vinny that his wastewater services business was worth meaningfully more than he had been hoping in some areas and meaningfully less in others, which is how these conversations usually go. The five municipal contracts (City of Westminster, City of Arvada, City of Wheat Ridge, plus two special-district sanitation authorities) with their combined recurring revenue spine, the in-house PACP-certified CCTV bench (six certified operators on three inspection trucks, allowing the company to self-perform municipal inflow-and-infiltration studies and condition assessments rather than subcontract), the I-70 industrial pretreatment cleanout book covering food processors and breweries and metal-finishing plating shops, the lift station service and maintenance recurring revenue, the fifteen-year clean NPDES discharge and environmental compliance record, the twelve-truck vacuum fleet with vintages averaging well inside remaining useful life, the thirty-year operating history under a single founder family across two generations, and Jorge’s twenty-six years of operational continuity were all premium-multiple drivers a sophisticated PE-backed water and environmental services consolidator would pay up for. Three issues, though, were dragging the number down. The first was the CDL driver retention story. Vinny had been keeping his fourteen CDL Class B tanker-endorsed vacuum truck operators with pay above market and a no-night-call policy on routine accounts, and his six PACP-certified CCTV inspection operators with comparable pay-above-market discipline, but the retention conversation was almost entirely verbal, and a sophisticated buyer’s diligence team was going to underwrite the driver bench (especially the PACP-certified inspectors and the lift station service technicians) as a transition-risk factor unless the company went to market with formal multi-year retention agreements in place. The second was the municipal contract change-of-control documentation. The five municipal contracts had renewal mechanics that the buyer’s diligence team would want to see formalized with explicit change-of-control language so the recurring municipal revenue would not be exposed to a counterparty re-bid inside the first eighteen to twenty-four months post-close. The third was the environmental tail-risk file. Wastewater services buyers diligence the regulatory file extensively because of the latent contamination, illegal dumping, and NPDES violation tail risk that runs longer than in most service businesses, and Vinny’s compliance file was already clean but the documentation needed to be organized in a way a buyer’s environmental counsel could walk through quickly.
We told Vinny honestly: he could go to market now and accept the discount, or he could spend four to five months getting Jorge, the general manager, the dispatcher, the four lift station service technicians, and the six PACP-certified inspectors on documented multi-year retention agreements, walking each of the five municipal contract administrators through a renewal that included explicit change-of-control transferability language, and reorganizing the environmental compliance file into a buyer-grade data room with the OSHA confined-space-entry program documentation, the DOT hazmat hauling file, the NPDES discharge records, and the historical incident log all in one place. We said the second path would likely command a meaningfully better number from a wider range of buyers, especially a top-tier PE-backed water and environmental services consolidator running a long-hold thesis with central regulatory and safety infrastructure. The realistic buyer pool for an $8.4 million revenue, $1.7 million EBITDA, twelve-truck wastewater services contractor with a PACP-certified CCTV bench, five municipal contracts, an I-70 industrial pretreatment book, and a clean environmental compliance file is wider than people think, but each band of buyer prices the same company differently, and the cleaner the diligence file is the more buyers can compete. CGK is an active member of the International Business Brokers Association and the M&A Source, both of which give us deep visibility into the active wastewater services buyer landscape, and we follow the trade through the National Association of Sewer Service Companies and the Water Environment Federation.
This is the part most brokers skip. Most brokers would have signed Vinny that day, taken him to market, and made the commission whether or not the deal was the best one for him. We told him to wait, even though it meant we did not get paid for five months and might never get paid at all if he changed his mind.
Vinny went home and waited. He spent the next five months getting Jorge on a four-year retention agreement with formal regional operations runway language, getting the general manager and the dispatcher on three-year retention agreements, getting each of the four lift station service technicians on two-year retention agreements with after-hours-rotation comp protection, getting each of the six PACP-certified CCTV inspection operators on two-year retention agreements with comp-step protections, walking each of the five municipal contract administrators (City of Westminster, City of Arvada, City of Wheat Ridge, and the two special-district sanitation authorities) through a renewal that included explicit change-of-control transferability language (all five signed updated agreements), and reorganizing the entire environmental compliance file into a buyer-grade data room. He read background material on wastewater services M&A through the National Association of Sewer Service Companies and stayed close to Water Environment Federation resources while watching consolidator acquisition announcements in the trade press. He called us back later that year and said he was ready to sell a wastewater services business that was finally in the shape it needed to be in.
What we did when Vinny came back.
What it takes to sell a wastewater services business properly
When an owner is ready to sell a wastewater services business with CGK, the speed of the on-ramp surprises them. We took Vinny’s company to market in just over six weeks once he got us his updated financials, the documented retention agreements with Jorge and the GM and the dispatcher and the four lift station service technicians and the six PACP-certified CCTV inspection operators, the formalized change-of-control language on all five municipal contracts (City of Westminster, City of Arvada, City of Wheat Ridge, and the two special-district sanitation authorities), the reorganized environmental compliance data room (OSHA confined-space-entry program, DOT hazmat hauling file, fifteen-year clean NPDES discharge record, historical incident log), the service-line-level revenue and gross margin breakouts for the trailing thirty-six months across the five lines (sewer cleaning and jetting and CCTV inspection, lift station service and maintenance, industrial pretreatment cleanout, grease trap pumping and grease-to-energy hauling, trenchless rehabilitation and miscellaneous repair), the customer-cohort analysis on the 250 private commercial accounts, the equipment-and-fleet schedule (twelve vacuum trucks, four high-pressure jetters, three CCTV inspection trucks, two service vans, with vintages and remaining useful life on each), the work-order-management software documentation, the lease terms on the Westminster yard, the CDL driver retention roster, and the PACP-certified inspector certification documentation. The blind teaser went out to forty-two buyers we had pre-qualified, a tight funnel because the wastewater services M&A buyer pool is structurally concentrated at this size band. Buyers fell across five buckets we routinely use to think about how to sell a wastewater services business: PE-backed water and environmental services consolidators (active across the Sun Belt, the Mid-Atlantic, and a few national platforms, typically running long-hold theses with central regulatory and safety infrastructure and acquiring under original company names with central support layered underneath), regional wastewater services aggregators (privately held, often family-owned, expanding their state or multi-state footprint through targeted acquisitions and typically operating acquired companies under their original brand names with smaller central support stacks), vertically-integrated waste hauling companies looking to add a wastewater services arm to their existing solid-waste operation, trenchless rehabilitation platforms acquiring CCTV-equipped service firms as entry points into new metros, and owner-operator buyers running personal-capital-plus-bank-financed acquisitions (the smallest band by check size, typically focused on single-truck or small-fleet operations rather than twelve-truck regional contractors). Each bucket prices the same company differently.
Thirty-one of the forty-two buyers signed NDAs and received the full Confidential Information Memorandum. Eighteen submitted Indications of Interest after data-room review. Ten advanced to Letters of Intent. We narrowed to six for management presentations. Four re-submitted refined LOIs after the management meetings. Two went into a final-final negotiation cycle. One pulled out late on a regulatory diligence concern that turned out to be a misread of a 2018 Westminster city audit that had been resolved at the time.
Vinny decided between two of the top LOIs. They were materially different. One was a slightly lower headline price from a regional wastewater services aggregator headquartered in Salt Lake City with operations across Utah, Idaho, and northern Nevada, around $32 million in annual revenue, and a tuck-in acquisition model where each acquired company kept its existing brand and was operated as a regional satellite. Under that LOI, the Westminster yard would keep its existing identity on the trucks, the truck shop bench would stay together, and Vinny would step back to a one-year transition consulting role at one day per week. The other was a higher headline price from a top-tier PE-backed water and environmental services consolidator running roughly $1.1 billion in annual revenue across more than 60 service centers nationally, comparable in scale to a Liquid Environmental Solutions or a Heartland Water Technology or an Inland Pipe Rehabilitation tier of platform, with a long-hold thesis (the platform was in its second PE ownership cycle and had publicly disclosed an intent to hold for at least another six to eight years), and a satellite-brand preservation acquisition model where the consolidator routinely acquired regional contractors under their original names with central regulatory and safety infrastructure, central CDL driver recruiting and retention infrastructure, central PACP and NASSCO certification cycle management, and central B2B contracting infrastructure layered underneath. Under that LOI, the Westminster yard would keep its existing identity on the trucks, the thirty-eight-person bench would stay at the yard, Jorge Mendoza would step into a Front Range regional operations role with the consolidator while keeping his Westminster yard responsibilities through a phased twenty-four-month transition, the general manager would continue running the bid-and-quote work on the municipal contracts with an expanded mandate that would route additional Front Range municipal opportunities through his desk, the dispatcher would continue running the daily run sheets, the four lift station service technicians would continue under their existing comp structure with the consolidator absorbing the after-hours emergency response phone integration, the six PACP-certified CCTV inspection operators would continue under their existing comp structure with the consolidator absorbing PACP and NASSCO certification cycle management, the fourteen CDL Class B tanker-endorsed vacuum truck operators would retain their pay-above-market structure under the consolidator’s central CDL retention program, the three industrial pretreatment cleanout crew leads and the two grease trap pumping route drivers and the two service van plumbers would retain their roles and pay structure, the five municipal contracts would transfer cleanly under the consolidator’s central B2B contracting umbrella with all five counterparties having pre-signed change-of-control acknowledgements, the work-order-management software would be retained for at least the first twenty-four months before any consolidation onto the consolidator’s enterprise stack, and Vinny would step back to a two-year transition consulting role at one day per week with full freedom to spend the rest of his time with Maria and the three grandchildren in Lakewood. We walked Vinny through what each LOI would actually deliver under realistic and pessimistic scenarios, including what the cultural continuity would look like for Jorge, the GM, the dispatcher, the lift station service technicians, the PACP-certified inspectors, the CDL drivers, the pretreatment crew leads, and the grease trap and service van staff under each acquisition structure. The PE-backed consolidator deal was the better one for Vinny. The headline number was higher. The brand preservation kept the trucks the trucks the customers and the municipal counterparties recognized. The Front Range regional operations runway gave Jorge a path forward that none of the other LOIs offered. The PACP and NASSCO certification cycle infrastructure took the regulatory file off Vinny’s safety and compliance manager’s desk in a way that would have been hard to replicate at the regional aggregator scale.
Through the whole process, the same CGK Managing Director who had taken Vinny’s first call five months earlier was the person walking him through every conversation.
The deal Vinny took to sell a wastewater services business.
How the deal looks when you sell a wastewater services business with CGK
This is the part of how to sell a wastewater services business that gets the least attention in the trade press and the most attention from owners who have actually closed a transaction: the structure of the consideration package matters more than the headline number, and the structure for a twelve-truck regional wastewater services contractor with five municipal contracts, an I-70 industrial pretreatment book, a PACP-certified in-house CCTV bench, and a clean fifteen-year environmental compliance file is a familiar pattern for a PE-backed water and environmental services consolidator running a long-hold thesis with a satellite-brand preservation acquisition model. Vinny’s deal closed roughly seven months after we restarted the engagement, the standard CGK wastewater services window. The buyer was a top-tier PE-backed water and environmental services consolidator with roughly $1.1 billion in annual revenue across more than 60 service centers nationally pre-acquisition, in its second PE ownership cycle with a publicly disclosed long-hold thesis through at least the next six to eight years, with a satellite-brand preservation acquisition model that routinely acquired regional contractors under their original names with central regulatory and safety infrastructure, central CDL driver recruiting and retention, central PACP and NASSCO certification cycle management, and central B2B contracting infrastructure layered underneath. The acquisition structure was an asset purchase rather than a stock purchase: the Westminster yard folded into the consolidator at close while keeping its existing identity on the trucks, the thirty-eight-person bench stayed at the yard, Jorge Mendoza stepped into a Front Range regional operations role with the consolidator while keeping his Westminster yard responsibilities through a phased twenty-four-month transition, the GM and the dispatcher continued in their roles, the four lift station service technicians and the six PACP-certified CCTV inspection operators continued under their existing comp structure, the fourteen CDL Class B tanker-endorsed vacuum truck operators retained their pay-above-market structure, all five municipal contracts transferred cleanly under the consolidator’s central B2B contracting umbrella with pre-signed change-of-control acknowledgements, and Vinny transitioned to a two-year consulting role at one day per week.
The total deal economic value was approximately $9.4 million, roughly 5.5 times trailing EBITDA, a strong regional wastewater services multiple driven by the five municipal contracts (each with formalized change-of-control language pre-signed), the in-house PACP-certified CCTV bench, the recurring lift station service and maintenance roster, the I-70 industrial pretreatment book, the clean fifteen-year NPDES discharge and environmental compliance record, the twelve-truck vacuum fleet with vintages averaging well inside remaining useful life, the thirty-year operating history under a single founder family, the diversified five-service-line revenue mix, and the structured succession story Vinny had built during the wait period with documented retention agreements on Jorge, the GM, the dispatcher, the lift station service technicians, and the PACP-certified CCTV inspection operators. About 81 percent of it came as cash at closing. About 9 percent was held back in escrow for 24 months, a longer-than-standard escrow window deliberately negotiated for the wastewater services environmental compliance and latent municipal-contract performance tail (environmental tail risk in this trade runs longer than the typical twelve-month service-business escrow because latent contamination, NPDES violation, and illegal-dumping claims can surface inside the eighteen-to-twenty-four-month window when a regulator audits a transferred file). The remaining 10 percent was a rollover-as-equity stake into the consolidator’s holding company, with Vinny’s existing equity converting into the consolidator’s holding-company partnership interests on a vesting schedule tied to his continued two-year consulting involvement and the consolidator’s long-hold thesis runway. The numbers add up to one hundred. Wire hit on a Friday morning at 9:47 a.m. while Vinny was at the Westminster yard with Jorge.
Vinny stayed on as a transition consultant for the consolidator’s Front Range region for twenty-four months after closing, dropping to one day per week so he could personally walk each of the five municipal contract administrators (City of Westminster, City of Arvada, City of Wheat Ridge, and the two special-district sanitation authorities) through the change-of-control handoff to the consolidator’s central B2B contracting team, accompany Jorge on the consolidator’s Front Range regional operations meetings, accompany the GM on the consolidator’s municipal bid-and-quote regional working group, walk the six PACP-certified CCTV inspection operators through the consolidator’s PACP and NASSCO certification cycle management infrastructure, walk the safety and compliance manager through the consolidator’s central regulatory and OSHA confined-space-entry program, and shape the consolidator’s Front Range expansion strategy across the additional Denver metro and Colorado Springs corridor sites the consolidator was already underwriting. After twenty-four months, Vinny stepped back to a quarterly clinical-advisor relationship that gave him room to spend the bulk of his weeks with Maria and the three grandchildren in Lakewood and on the Italian-American community work he had been involved with in north Denver and Westminster.
What happened to Vinny’s people and his customers.
The people-side of how to sell a wastewater services business usually weighs heavier on the founding operator than the financial-side, even when the financial-side is what triggers the call to a broker in the first place. Vinny cared most about Jorge Mendoza (the truck shop foreman and dispatch lead, twenty-six years), the general manager he had brought in from a Denver-area competitor in 2019, the dispatcher who routed the daily run sheets, the fourteen CDL Class B tanker-endorsed vacuum truck operators, the six PACP-certified CCTV inspection operators, the four lift station service technicians who carried the after-hours emergency response phone, the three industrial pretreatment cleanout crew leads, the two grease trap pumping route drivers who ran the route his father Salvatore had started in 1972, the two service van plumbers, the four office and administration staff, the safety and compliance manager, and the customer base: the five municipal contracts (City of Westminster, City of Arvada, City of Wheat Ridge, and the two special-district sanitation authorities) with their combined recurring revenue spine, the 250 private commercial accounts including the I-70 industrial corridor pretreatment customers, and the route book of restaurants and institutional kitchens. The PE-backed water and environmental services consolidator buyer was a top-tier platform running a satellite-brand preservation acquisition model that routinely acquired regional contractors under their original names rather than rebranding under a national identity on a tight ninety-day timeline. That made the people part substantially cleaner than it would have been under a vertically-integrated waste hauler that wanted to absorb the Westminster yard into a single corporate identity.
The buyer kept all thirty-eight W-2 employees, honored the existing pay structure across the truck shop and dispatch and the field crews, and committed to keeping Jorge Mendoza running the Westminster yard while stepping into the consolidator’s Front Range regional operations role on a twenty-four-month phased transition, the GM continuing on the bid-and-quote work for the municipal contracts with an expanded Front Range mandate, the dispatcher continuing on the daily run sheets, the four lift station service technicians continuing on the after-hours emergency response phone under their existing rotation, the six PACP-certified CCTV inspection operators continuing on the in-house municipal inflow-and-infiltration and condition assessment work, and the fourteen CDL drivers retaining the pay-above-market and no-night-call discipline that had kept Vinny’s bench full when his regional competitors were chronically short. The retention work Vinny had done during the wait period (formalizing the four-year agreement with Jorge, the three-year agreements with the GM and the dispatcher, the two-year agreements with the four lift station service technicians and the six PACP-certified inspectors) was preserved with formal employment agreements at or above the existing comp model. The fourteen CDL drivers retained their roles and existing scheduling structure. The three industrial pretreatment cleanout crew leads retained their roles. The two grease trap pumping route drivers retained the route his father Salvatore had started in 1972. The two service van plumbers retained their roles. The four office and administration staff retained their roles. The safety and compliance manager retained the OSHA confined-space-entry program, the DOT compliance file, and the NPDES discharge documentation through a phased eighteen-month integration window before any consolidation onto the consolidator’s central regulatory infrastructure. The five municipal contracts (City of Westminster, City of Arvada, City of Wheat Ridge, and the two special-district sanitation authorities) transferred cleanly under the consolidator’s central B2B contracting umbrella, with all five counterparties having pre-signed change-of-control acknowledgements during the wait period. The work-order-management software was retained for the yard through a twenty-four-month integration window. The 250 private commercial accounts on the I-70 industrial pretreatment book and the restaurant and institutional kitchen route stayed firmly attached to the existing crews because the trucks and the people stayed in place.
Vinny was at the Westminster yard on a Friday morning when the wire confirmation came through. Wastewater services closings often happen at the end of the week to clear the books before the weekend on-call rotation. Jorge had just finished the morning equipment walk-through across the vacuum and jetter fleet. Vinny stepped onto the yard apron, pulled Jorge aside near the truck shop bay, said “Esta hecho, Jorge. Gracias por veintiseis años.” It is done. Thank you for twenty-six years. Jorge did not say anything for a few seconds. He put one hand on Vinny’s shoulder and then turned back to the yard because the second wave of vacuum trucks was about to roll out for the morning lift station rotation. Vinny pulled out his phone and called Maria first, before he called Anthony in Boulder or Gianna in Portland. He just said “Maria, è fatto. Grazie a Dio.” Maria, it is done. Thanks be to God. Maria did not say anything. She breathed out for a long second on the other end of the line. Then she asked when he was coming home for lunch, because she had pulled out the gravy and the sausage from the freezer the night before and put it on the stove that morning before he had even left for the yard.
What Vinny told us afterward.
Why owners who sell a wastewater services business with CGK keep coming back
Most owners who sell a wastewater services business do not call the broker again in the first year. The ones who do call usually want to talk about the parts of the engagement that, in retrospect, mattered more than they realized at the time. About eight months after closing, Vinny called the Managing Director who had run his engagement. He said two things that the Managing Director still tells new sellers about.
The first was about the five-month wait. He said: “Three of the buyers who had been calling me were ready to sign LOIs in thirty days, and two different consolidator scouts I talked to before you told me they could take me to market right then with the Jorge retention conversation still on a verbal handshake, the five municipal contracts still on their original renewal mechanics with no change-of-control language, and the environmental compliance file in three different file cabinets across the office. The reason I sold with you is that you told me the truth about how my five municipal contracts and my PACP-certified CCTV bench and my fifteen-year clean NPDES record were actually being valued by a sophisticated PE-backed water-services consolidator underwriter, the truth about what the formal Jorge and GM and dispatcher and lift station and PACP retention agreements would buy me in LOI conversations five months later, and the truth about what the change-of-control language across the five municipal contracts would buy me in management presentations. You told me what would happen to the price if I went out without fixing those things. I would have left more than a million and a half dollars on the table, and Jorge and the GM and the dispatcher and my driver bench would have folded into a worse comp tier under a different operator.”
The second was about who he sold to. He said: “I almost signed with the Salt Lake regional aggregator because the conversation felt familiar and they told me they could close in sixty days. The fact that you walked me through what each buyer would actually do with Jorge’s Front Range regional runway, with the GM’s municipal bid-and-quote mandate, with the truck shop my father Salvatore had started in 1972, with the route book my father had started pumping grease traps along in north Denver, and with the customer base I had spent thirty years building, what each buyer’s brand-and-bench integration thesis would mean for the PACP-certified bench and the lift station service technicians three and five years out, and how a top-tier PE-backed water-and-environmental-services consolidator with a satellite-brand preservation thesis and a long-hold runway was structurally different from a regional aggregator with a smaller central support stack, is a conversation I never even thought to have until you raised it. I sold to a buyer who is actually going to keep the Westminster yard the yard my customers know, who is actually going to keep my father’s grease trap route under the same trucks, and who is going to give Jorge a Front Range regional runway he could not have built on his own.”
This is what we mean when we say we sit with you in the decision, not just the transaction. Vinny is one composite story, but the pattern is real. The owners we work with who decide to sell a wastewater services business usually find their way to us through versions of Vinny’s situation, and the relationships start with a long listening session and a free walkthrough, not a pitch.
Ready to sell a wastewater services business? Where are you in Vinny’s story?
If you are starting to think about how to sell a wastewater services business, we should talk. There is no commitment and no pressure. The first conversation is free. The valuation walkthrough that follows is free when you are seriously thinking about selling, whether that is in a year, five years, or longer. We only charge for formal written valuations, and only when you actually need one for a partnership buyout, estate planning, or another documentary purpose. Submit the form and a senior CGK Managing Director will reach out within one business day.
If you are Vinny at month 1: just exploring
You are not sure if you want to sell yet. The wastewater services M&A landscape keeps shifting (PE-backed water and environmental services consolidators, regional aggregators, vertically-integrated waste haulers, trenchless rehabilitation platforms, owner-operator buyers), your truck shop foreman and lift station service technician retention conversations are still on verbal handshake terms, your municipal contracts are running on their original renewal mechanics with no change-of-control language, your PACP-certified CCTV bench is being treated by your bookkeeper as a single line item rather than as a strategic asset, twenty-five-plus years of running the trucks is starting to tell you something, your kids are not coming back to run the yard, you are curious about how a buyer would value your sewer-cleaning-and-jetting mix versus your lift station service exposure or your industrial pretreatment book, or maybe a PE-backed consolidator or a regional aggregator has been calling you. Most of our best engagements start here. Submit the form and we will schedule a working session. You walk away with a real number and a clear sense of what to do next, with no obligation to do anything.
If you are Vinny at month 5: ready to go
You have done the work to clean up the company. The financials are tight. Your truck shop foreman and lift station service technician and PACP-certified inspector retention agreements are documented with multi-year stay arrangements. Your CDL driver pay-above-market discipline is documented. Your municipal contracts are formalized with explicit change-of-control transferability language. Your service-line revenue and gross margin breakouts are pulled into a buyer-grade report for the trailing thirty-six months. Your sub-mix breakouts (sewer cleaning and jetting and CCTV inspection, lift station service and maintenance, industrial pretreatment cleanout, grease trap pumping, trenchless rehabilitation) are clean. Your fleet vintage and remaining-useful-life schedule is current. Your OSHA confined-space-entry program documentation, DOT hazmat hauling file, and NPDES discharge record are organized in a buyer-grade data room. Your PACP and NASSCO certification documentation is current. Maybe a buyer is already in the conversation. You want to run a real process. Submit the form and we will be in touch within a business day to talk about timing, scope, and what your first 30 days as a CGK seller would look like.
If you are not sure where you are
Most owners are not sure. Submit the form and start with the conversation. We will figure out together where you are. We are equally happy to tell you to wait twelve months as we are to take you to market in six weeks.

What sellers say after they sell a wastewater services business (and other businesses) with CGK
I could not be happier with the experience I had selling my business with CGK. Greg did a detailed analysis of my business and helped me price and position it right for the market. After receiving multiple offers at full asking price, the rest of the process went very smoothly, and we closed in less than two months.
Hanna M.Selling my business was a once-in-a-lifetime experience, and I’m incredibly grateful to have had Wes by my side throughout the process. He brought perspective, pushed when necessary, and always had my best interests in mind. His experience and strategic approach allowed me to maximize the sale price while minimizing long-term risk and obligations. If I had to do it all over again, I wouldn’t hesitate to choose him as my broker.
Adam NevilleDerik located multiple interested strategic buyers that produced more than one serious offer. The negotiations were tough but Greg and Derik’s experience helped us overcome. We got a great result for our employees and for the owners. We would recommend them without reservation.
Bob TaylorWe sold a business that was 47 years old and being run by second generation within a year of working with Wes. CGK has a system that attracts serious prospects to review opportunities. Wes was able to make the overwhelming feeling of selling easy and to a certain extent enjoyable. I never felt alone or in the dark throughout the entire process.
Jennifer WilliamsWe decided to sell our company in 2025. Talked to another M&A company in the Houston area. We felt very comfortable with Greg and Matthew at CGK. Could not have made a better choice. From day 1 till final closing and even after 30+ days, they have been here helping us with documents and support during the transition. Thanks can not be said enough.
Rickey ThomasInside the Blueprint, on Bloomberg TV and Fox Business News.
Vinny’s son Anthony, the commercial real estate developer in Boulder, was the one who first sent him a clip of CGK on Bloomberg. He had been watching the segment in his Boulder office on a Tuesday morning between meetings with a Pearl Street investor and recognized the firm name from a regional water and environmental services M&A trade article about how to sell a wastewater services business he had read a few months earlier. He texted his father the link with a note that read “Pop, watch this. This looks like the right firm for the conversation you and Mom keep having.” CGK Business Sales is featured on Inside the Blueprint, the syndicated business television series. Our episode aired on Bloomberg TV and Fox Business News. Watch the segment, then start a confidential conversation.
The CGK office Vinny called was the CGK Denver office. Yours might be one of these.
When you sell a wastewater services business with CGK, whichever office you reach, you get the entire firm. Vinny worked with a CGK Managing Director based out of the firm’s Denver office, but his deal benefited from a buyer pool we sourced firm-wide, including the top-tier PE-backed water and environmental services consolidator that ultimately won the engagement.
