Storm Drain Cleaning Service
Dirty municipal work with compliance tailwinds and almost no glamour competitors
Bottom line
Worth studying, but do not buy without strong local proof.
Storm drain cleaning services vacuum debris, flush catch basins, clean lift stations, and maintain drainage infrastructure for municipalities, property managers, HOAs, industrial sites, and retail centers. Listings on BizBuySell regularly bundle storm drain work into liquid-waste and environmental service companies with seven-figure revenue profiles. The surprising angle is that clogged drainage is not optional, and recurring compliance-driven contracts can make this filthy niche more predictable than prettier service businesses.
How It Works
The company uses vacuum trucks, jetting equipment, and field crews to clean drains, basins, grease systems, and related infrastructure on a scheduled or emergency basis. Revenue comes from recurring service agreements, municipal contracts, environmental compliance needs, and urgent callouts after storms or flooding.

Storm Drain Cleaning Service
Revenue drivers
- • Catch-basin and inlet counts cleaned per truck-day
- • Hydro-jetting, vacuuming, CCTV, and compliance documentation bundled per site
- • Municipal, HOA, retail-center, and industrial recurring maintenance contracts
- • Emergency flood, blockage, and post-storm response calls
- • Disposal logistics and sediment/debris handling discipline
Key risks
- • A vactor truck can cost more than the seller's claimed annual SDE if replacement is near
- • Municipal bids can look recurring but reset on price every contract cycle
- • Sediment disposal and documentation failures can erase customer trust
- • Low utilization makes expensive trucks sit while debt and insurance keep running
- • Emergency revenue may depend on the owner personally answering the phone
What you need to believe
- Regulatory and flooding pain converts into repeat work
- The truck has enough paid hours to justify its fixed cost
- Cleaning counts and disposal records prove revenue
- Contracts survive closing and are not purely relationship-driven
- The buyer can retain crews willing to do wet infrastructure work
Unit economics
How one unit makes money
Modeled per one vactor-truck crew cleaning catch basins, storm lines, and related drainage assets. Every line shows its arithmetic — rebuild any number yourself.
Revenue build-up
| Line | Low | Base | High |
|---|---|---|---|
| Scheduled catch-basin / inlet cleaning2,000-5,000 structures/year × $175-$280 per structure; operator pricing shows ~$125-$300 per basin | $350K | $700K | $1.4M |
| Hydro-jetting, vactor hourly work, CCTV support500-1,500 billable crew-hours/year × $320-$600 blended truck/crew rate | $160K | $405K | $900K |
| Emergency, post-storm, and compliance reporting projects60-250 urgent or documented compliance jobs/year × $1,000-$3,600 | $60K | $293K | $900K |
Where it goes — cost structure
- Field labor, overtime, traffic control, safety24–34%
Crews work around roads, parking lots, water, and heavy lids; cheap labor becomes claims and callbacks.
- Vactor truck fuel, maintenance, debt, replacement reserve15–25%
A single combination truck is both the revenue engine and the capex cliff.
- Sediment/debris disposal and dump time6–12%
EPA maintenance guidance explicitly calls for sediment logs; disposal is operational evidence, not just a cost line.
- Insurance, permits, bonding, reporting5–9%
Municipal and HOA buyers pay for defensible documentation after the basin is clean.
- Dispatch, sales, bidding, yard, admin7–12%
Recurring schedules need account management; municipal work needs bid discipline.
What actually swings the deal
- Structures cleaned per year
±500 basins at $200 each ≈ ±$100K revenue; basin count × invoice price × disposal log is the diligence shortcut.
- Average price per basin
$25 of underpricing across 3,500 annual structures ≈ $87.5K revenue before extra cost.
- Vactor utilization
+1 billable 8-hour truck day/month at $450/hr ≈ +$43K revenue, which matters because the truck costs run while parked.
- Disposal and dump-time drag
a 4-point disposal/dump-time miss on $1.4M revenue is ~$56K of SDE; dirty basins that take twice as long need different pricing.
Benchmarks to memorize
A single vactor truck cleaning 3,500 basins and selling ~900 jetting/CCTV hours is already near a $1.4M revenue route. Past that, growth usually means a second truck, municipal step-up, or tighter pricing — not squeezing infinite work from the same crew.
Market analysis
Who owns these & where demand comes from
Fragmented infrastructure service market: small vactor operators, sewer cleaners, septic/liquid-waste companies, and municipal contractors overlap. Demand is local because the truck, crew, basin inventory, dump site, and weather all sit in the same geography.
Tailwinds
- ↗ Stormwater compliance is becoming more data-driven, making photo/GIS/reporting discipline valuable
- ↗ Aging drainage infrastructure gives municipalities more basins to maintain than crews to handle internally
- ↗ Ugly wet work and high equipment cost protect competent independents from casual competitors
Headwinds
- ↘ Municipal bids can reset at lower prices if the contractor cannot show measurable basin outcomes
- ↘ Vactor truck replacement and repair inflation can outrun small-owner reserves
- ↘ Labor and safety execution are non-negotiable around traffic, confined spaces, and heavy lids
Demand drivers
- EPA and state stormwater programs push municipalities and property owners toward documented maintenance schedules
- HOAs, retail centers, and industrial sites need parking-lot drainage to work before storms expose failures
- Sediment, trash, leaves, and hydrocarbons accumulate continuously in catch basins
- Post-storm flooding turns deferred maintenance into urgent high-ticket work
Regulation
Stormwater maintenance is local but tied to NPDES/MS4-style permit expectations. The practical requirement is inspection frequency, cleaning logs, sediment disposal records, traffic control, and contractor licensing in the market.
Who you bid against
Bidders include local sewer cleaners, septic/liquid-waste operators, municipal contractors, and infrastructure-service searchers. The best strategic buyer already runs nearby vactor routes and can tuck in contracts without buying another yard.
Competitive advantage
What protects the good ones
- strongEquipment and response capacity
Customers need a truck that can remove sediment and water today. A booked, maintained vactor fleet beats a low-price contractor waiting on rentals.
- moderateCompliance-grade documentation
EPA guidance points to maintenance logs and sediment records. Before/after photos, basin IDs, and disposal receipts make renewal easier.
- moderateMunicipal / HOA contract relationships
Recurring schedules and bid familiarity create stickiness, though many contracts still reprice periodically.
- moderateRoute density around basin clusters
HOAs, retail centers, and municipal zones turn cleaning into a basin-density business; one-off emergency calls are less defensible.
Who wins — and who loses
The winner knows every basin ID, debris load, disposal receipt, and renewal date in a metro cluster, then sells cleaning as risk control before the next storm. The loser owns an expensive vactor truck, waits for flood calls, quotes hourly, and cannot explain why two basins on the same property produced different margins.
How this niche degrades
- ↘ Municipal procurement compresses margins if the service is sold as generic hourly truck time instead of documented asset maintenance.
- ↘ New entrants can rent equipment for one-off jobs, but recurring compliance work requires logs and references.
- ↘ More intense rain increases demand but also stresses crew scheduling and emergency overtime.
- ↘ Tighter sediment-handling rules turn undocumented operators into acquisition discounts or no-bids.
Still local. The SBA enrichment is the same miscellaneous-waste slice as liquid waste, with only 22 observed loans and ~9% franchise share; strategic buyers are usually adjacent septic/liquid-waste/stormwater operators.

Valuation framework
How these actually get priced
Valued on SDE with a heavy equipment and contract-quality overlay. A buyer should not pay the same multiple for emergency-only vactor work as for documented recurring basin maintenance with clean disposal records and transferable schedules.
What moves the multiple
- ▲ PremiumRecurring contract schedule
Annual municipal, HOA, and commercial schedules with renewal history support the high end; one-off storm response does not.
- ▼ DiscountFleet age and uptime
Near-term vactor replacement or major pump repairs should be deducted before applying the multiple.
- ▲ PremiumDocumentation quality
Basin IDs, before/after photos, sediment logs, and disposal records make the revenue more transferable and financeable.
- ▼ DiscountCustomer concentration / bid reset risk
A single municipal contract near rebid can make trailing SDE less durable than it looks.
Worked example
At the profile midpoint, $1.4M of revenue at a 24% margin produces about $336K of SDE. At the 2.4-3.9× category range, that implies roughly $806K-$1.31M of value. The top end requires recurring schedules, clean documentation, and a healthy vactor fleet; subtract truck capex and rebid risk before valuing last year's storm calls.
Common buyer mistakes
- ✕ Applying a multiple to revenue before proving basin counts and truck utilization
- ✕ Treating municipal work as recurring when the contract is up for bid next spring
- ✕ Ignoring disposal logs because the visible job was done when the basin looked clean
- ✕ Underwriting a truck fleet at book value instead of replacement cost and downtime risk

Due diligence checklist
Before you sign anything
- 01
Rebuild revenue from basin/structure count, price per structure, truck hours, disposal loads, and customer by month.
The model depends on 3,500 cleaned structures and 900 billable hours, not generic service revenue.
Red flagRevenue cannot be tied to physical basins, truck time, and disposal evidence. - 02
Pull sample job packets: before/after photos, basin IDs, sediment amount, disposal receipt, and customer report.
Documentation is the moat and the compliance value customers renew for.
Red flagThe seller's proof is a paid invoice and nothing about what was removed. - 03
Inspect fleet condition, utilization, maintenance history, and replacement estimates for every vactor/jetter/CCTV unit.
Truck uptime drives the utilization sensitivity and real purchase price.
Red flagOne aging truck produces most revenue and has no backup or reserve. - 04
List all recurring contracts with start date, renewal date, pricing basis, assignment rights, and rebid history.
Recurring stormwater maintenance deserves a higher multiple only if it survives closing.
Red flagMajor accounts renew by low-bid RFP within 12 months. - 05
Map disposal sites, fees, accepted debris/waste classes, and drive time from major customer clusters.
Disposal drag is a direct SDE sensitivity and can turn dirty basins into bad jobs.
Red flagCrews drive across the metro to dump because no nearby site is available. - 06
Separate emergency revenue from scheduled work and identify who took the call, quoted it, and dispatched the crew.
Emergency upside is valuable only if it is not seller-dependent chaos.
Red flagMost high-margin calls came through the seller's personal phone.
Pros
- +Essential work tied to safety and compliance
- +Repeat revenue from municipalities and commercial properties
