How Sewer Inspection & Repair Deals Get Structured

From SBA 7(a) financing to equity rollovers, here is how buyers and sellers in the CCTV inspection and trenchless repair industry structure acquisitions in the $1M–$5M revenue range.

Sewer inspection and repair businesses — particularly those with CCTV inspection fleets, CIPP lining capabilities, and municipal master service agreements — transact at EBITDA multiples of 3.5x to 6x depending on revenue quality, equipment condition, and contract transferability. The equipment-heavy nature of these businesses, combined with the licensing requirements for NASSCO-certified technicians and the complexity of municipal contract assignments, makes deal structure more nuanced than in lighter-asset service businesses. Most transactions in this space fall into one of three structures: SBA 7(a) financed deals with a seller note bridging the equity gap, all-cash strategic acquisitions with a consulting transition agreement, or equity rollover structures used by PE-backed roll-up platforms. The right structure depends on whether the buyer is an owner-operator using SBA financing, a strategic acquirer with existing infrastructure cash, or a platform seeking to retain the seller as a minority partner. Understanding the tradeoffs of each approach — and how factors like municipal contract transferability, deferred equipment capex, and owner dependency affect deal terms — is essential for both buyers and sellers entering a transaction.

SBA 7(a) Loan with Seller Note

The buyer uses an SBA 7(a) loan to finance the majority of the purchase price, contributing 10–15% equity down and negotiating a seller note for the remaining gap between the loan amount and the total deal price. The seller note is typically subordinated to the SBA loan and carries a 6–8% interest rate with a 3–5 year repayment term. This is the most common structure for first-time buyers or owner-operators acquiring a sewer inspection company without institutional capital backing.

60–70% SBA loan, 10–15% buyer equity, 15–25% seller note

Pros

  • Allows buyers to acquire a $2M–$4M sewer inspection business with as little as $200K–$400K in equity out of pocket
  • Seller note aligns seller incentives with a smooth transition since the seller has deferred consideration at risk
  • SBA lenders experienced in trades and utilities industries will credit-approve businesses with verified municipal contracts and documented equipment values

Cons

  • SBA lenders require a full business appraisal and equipment appraisal, which can be time-consuming and expensive for fleets of CCTV trucks and jetting units
  • Seller note subordination means the seller collects nothing on deferred consideration until the SBA loan is in good standing, creating risk if the business underperforms post-close
  • Municipal contract assignment delays or customer attrition during the transition can trigger covenant issues on the SBA loan if revenue drops materially

Best for: First-time buyers or owner-operators with plumbing or excavation backgrounds acquiring a profitable sewer inspection and repair company with clean financials and a diversified contract base

All-Cash Acquisition with Transition Consulting Agreement

A strategic acquirer — typically a regional plumbing company, drain cleaning platform, or PE-backed home services roll-up — pays cash at closing and retains the seller under a 90–180 day consulting agreement to ensure contract continuity, introduce the buyer to municipal clients, and transfer operational knowledge. The seller receives a clean exit with no deferred consideration, and the buyer gets full ownership and operational control from day one.

100% cash at closing, consulting fee of $10K–$20K per month for 90–180 days paid separately

Pros

  • Seller receives full payment at closing with no contingent consideration tied to post-close performance of contracts or equipment
  • Buyer gains immediate control over equipment deployment, technician management, and contract pricing without sharing economics with the seller
  • Consulting agreement structures a defined knowledge transfer period covering NASSCO certification management, municipal account relationships, and proprietary inspection reporting workflows

Cons

  • Buyer assumes full risk of municipal contract non-renewal or customer attrition without any seller skin in the game post-close
  • All-cash deals often require a higher purchase price to compensate the seller for giving up deferred upside, increasing buyer's total capital at risk
  • Consulting agreements can create ambiguity around authority and decision-making if the outgoing owner and new management have conflicting views on operations during the transition

Best for: Strategic acquirers or PE-backed platforms with existing capital, operational infrastructure, and the ability to absorb contract risk, acquiring a well-documented business with transferable municipal MSAs

Equity Rollover with Reduced Upfront Payment

The seller retains a 10–20% equity stake in the acquiring platform or newly formed holding company in exchange for a lower upfront cash payment. This structure is commonly used by PE-backed roll-up platforms building out a regional sewer inspection and trenchless repair portfolio. The seller participates in future value creation when the platform is recapitalized or sold, effectively trading immediate liquidity for potential upside.

75–85% cash at closing, 10–20% equity rollover into the acquiring platform at agreed valuation

Pros

  • Seller retains meaningful upside if the acquiring platform successfully scales the business through additional contracts, geographic expansion, or CIPP lining volume growth
  • Buyer pays a lower upfront price, preserving capital for equipment investment, working capital, and add-on acquisitions
  • Aligns seller's long-term incentives with the success of the combined platform, reducing the risk of a passive or disengaged transition

Cons

  • Seller's retained equity is illiquid until a future platform sale or recapitalization event, which may be 3–7 years away with no guaranteed outcome
  • Valuation of the rollover equity stake is complex and often contentious, particularly for sellers without experience evaluating PE fund economics or waterfall structures
  • Seller must accept minority shareholder status with limited control rights, which can be uncomfortable for founders accustomed to full operational authority

Best for: Experienced owner-operators who believe in the long-term value of the roll-up thesis and want to participate in platform upside rather than taking a one-time exit at a lower standalone multiple

Negotiation Tips for Sewer Inspection & Repair Deals

  • 1Request a full equipment appraisal from a qualified fleet appraiser before finalizing the purchase price — aging CCTV cameras, jetting trucks, and CIPP lining units can represent $300K–$800K in deferred replacement costs that should reduce the headline multiple or be structured as a post-close capital credit
  • 2Verify the transferability of every municipal and commercial master service agreement before closing; some municipal contracts require a formal assignment approval process that can take 60–120 days and should be built into the transaction timeline as a condition precedent
  • 3If the seller is the primary relationship holder with municipal clients, structure an earnout or seller note with a portion tied to contract retention at 12 months post-close to keep the seller financially motivated to execute a clean handoff
  • 4Negotiate a clear scope and compensation structure for the seller's post-close transition role — whether it is a consulting agreement or employment arrangement — before the LOI is signed to avoid ambiguity during due diligence
  • 5For SBA-financed deals, work with an SBA lender experienced in equipment-heavy services businesses who understands how to underwrite CCTV fleet values, technician workforce risk, and the revenue predictability of municipal inspection contracts
  • 6Build an environmental indemnification clause into the purchase agreement that protects the buyer from pre-close liability related to sewer overflow events, EPA violations, or improper disposal of inspection byproducts, with seller indemnity surviving closing for a minimum of 3 years

Frequently Asked Questions

What EBITDA multiple should I expect for a sewer inspection and repair business?

Most sewer inspection and repair businesses in the $1M–$5M revenue range sell for 3.5x to 6.0x trailing twelve-month EBITDA. Businesses at the high end of the range typically have long-term municipal master service agreements with automatic renewal provisions, a NASSCO-certified workforce that is not dependent on the owner, modern and well-maintained CCTV and CIPP lining equipment, and diversified revenue across inspection, lining, spot repair, and emergency services. Businesses closer to 3.5x often have aging equipment, owner dependency, or revenue concentrated in a single municipal or commercial client.

Can a sewer inspection business be financed with an SBA loan?

Yes. Sewer inspection and repair businesses are SBA-eligible, and SBA 7(a) loans are commonly used by buyers in this space. The SBA will lend against the enterprise value of the business, and lenders will require a business appraisal, an equipment appraisal for the CCTV fleet and jetting units, three years of tax returns, and verification of any municipal contracts. Buyers typically contribute 10–15% equity down, with a seller note of 15–25% bridging the gap between the loan amount and total deal price. SBA lenders experienced in trades and utility services are best positioned to underwrite these transactions efficiently.

Are municipal sewer contracts transferable when the business is sold?

It depends on the contract language and the municipality's procurement rules. Some municipal master service agreements contain assignment clauses that permit transfer to a new owner with written consent from the municipality, while others require the contract to be re-bid when ownership changes. Buyers should conduct a thorough review of every municipal contract during due diligence, and sellers should proactively contact municipal clients early in the process to understand assignment requirements. Transactions where contract transferability is uncertain often include earnout provisions tied to contract retention to protect the buyer's invested capital.

What happens if the owner is the only NASSCO-certified operator or the primary estimator?

Owner dependency is one of the most significant value killers in this industry. If the founder is the sole licensed operator, primary estimator, or only person managing municipal relationships, buyers will discount the purchase price or structure a larger portion of consideration as deferred through earnouts and seller notes to account for transition risk. Sellers preparing for exit should invest 12–24 months before going to market in cross-training a lead technician or operations manager to handle estimating, NASSCO certification requirements, and key client communication so the business can operate independently of the owner.

How is equipment value handled in a sewer inspection business acquisition?

Equipment — including CCTV inspection cameras, jetting trucks, pipe-lining units, and robotic cutters — is typically included in the total enterprise value of the business rather than purchased separately unless the deal is structured as an asset sale with a separate equipment schedule. Buyers should obtain an independent equipment appraisal to verify fair market value and identify any deferred maintenance or near-term replacement needs. Sellers should present clean maintenance logs and service records for all units to support full equipment value. In SBA-financed deals, equipment appraisal is a lender requirement and directly affects the loan amount the buyer can access.

What is an earnout and when is it used in sewer inspection deals?

An earnout is a portion of the purchase price that is paid to the seller after closing, contingent on the business meeting specific performance targets — most commonly municipal contract retention, revenue thresholds, or EBITDA goals measured 12–24 months post-close. Earnouts are most commonly used in sewer inspection deals when there is uncertainty about whether key municipal contracts will successfully transfer to the new owner, when the seller is the primary relationship holder and there is transition risk, or when the buyer and seller cannot agree on a headline valuation and the earnout bridges the gap by tying a portion of payment to future performance.
