What work does the water-reuse business actually sell?
Separate system design and installation from checks, service visits, repairs, and reports so the buyer can identify which duties earn fees and which belong to another party. A project invoice does not prove that the company has a contract for future care.
EPA's onsite non-potable reuse resource page describes treated onsite water used for purposes other than drinking, at building or district scale. Its links to different state resources provide context without giving every plumber the right to build, run, or service every system.
Start with the target's invoices and customer terms, listing each site's work sold, named customer, assigned person, and remaining promise. Check whether one fee includes duties that continue after the job appears finished.
The market hub helps compare buyers for this niche. A buyer who can run a repair crew still needs staff, access, records, and permits for the service model it plans to keep.
Which permits and approvals govern each acquired site?
Get each site's current permit, approved plan, system manual, and authority contact, confirming who holds the permit and is named to manage the system. Ask which changes need notice, a new filing, or approval.
San Francisco's current program page gives a local example of separate plan, health-permit, testing, startup, and final-use steps. Those requirements apply within that program rather than establishing a complete rule for a site in another city.
The page also flags draft rules under public review from September 24 through October 26, 2026, when the proposal is still under consideration rather than adopted. Ask the authority which current duties apply and whether a later change may affect the buyer's plan.
Keep proof of acceptance in the closing file, treating the permit application, signed contract, and system ready for use as different facts. The buyer should know which of those facts must be established before taking over a particular duty.
Who checks the system and sends the required reports?
Name a person for each check, visit, report, and fault response, matching the role to the permit, approved manual, customer contract, and needed skills. A promise that the seller will remain available by phone may leave daily work without an owner.
San Francisco's September 2025 guidebook describes ongoing monitoring and reports to keep a permit valid, with schedules that vary by system and operating mode. Use this as a dated local example, then confirm the current terms for the actual site and buyer.
Collect logs, sent reports, receipt or acceptance records, and open issues, asking staff to explain any missed entry or late report. A full folder does not establish that every required task was done on time.
The skilled-trades labor guide adds questions about staff coverage. Budget time for visits, report work, training, travel, and backup even when the customer's service fee is fixed.
How do cross-connection records affect the handoff?
Keep approved water paths and testing records tied to the actual system, confirming which devices, checks, and reports the water supplier and site authority require. Ask qualified people to review gaps; a business-sale document cannot establish that a system is safely arranged.
EPA's distribution resources list guidance on cross-connections and backflow without setting one test interval or approval route for every reuse site. Get the receiving authority's current requirements rather than treating the general guidance as a local permit.
A reuse-service duty map is the record linking a site's required checks, reports, repairs, and response roles to its permit and customer terms. It helps a buyer find handoff gaps without providing a technical design or proof that the system passed a test.
Use the qualifying-party definition where covered plumbing work needs licensed supervision, keeping that role separate from the system manager and report sender. Confirm which people may perform each task instead of treating one license as authority for every duty.
What can a simple account example reveal about cost?
Test the fee against the promised work using completed visits and reports to replace rough estimates with observed costs. Keep new services and hoped-for renewals separate from the customer's signed terms.
Consider an illustrative example with no real target data. A customer pays $600 a month for an agreed service package. Assume the monthly visit uses three paid hours at $50 an hour, travel costs $40, and report work uses one hour at the same $50 rate. Those items total $240, leaving $360 before the other costs of running the business.
That $360 is not EBITDA or cash free for debt service. The plan still needs parts, insurance, office costs, repairs, taxes where relevant, and any other promised work. If an extra fault visit uses two hours, the assumed labor alone adds $100. The fixed customer fee has not changed.
Use the service-agreement revenue definition to keep repeat fees and remaining work linked, then ask the CPA how paid but undelivered service enters the closing terms. The example shows a cost test, not a market price or a claim that every system uses this schedule.
Which records should the buyer accept before closing?
Review the full chain from customer promise to completed work. Find the cause of a missing record before deciding whether to recover a file, complete a task still due, or change the forecast for that account.
| Review field | Records to inspect | Decision before takeover |
|---|---|---|
| Customer promise | Signed scope, fee, notice and transfer terms | Which duties has the customer bought? |
| Site authority | Permit, approved plan, named roles | What changes need acceptance? |
| Checks and reports | Logs, sent reports, open faults | What work is complete or still due? |
| Water separation | Device records and accepted tests | Which gaps need a qualified review? |
| Staff and access | Duties, skills, site keys, backup plan | Who can perform the next task? |
| Service economics | Visits, paid time, parts, bills, cash | Does the fee fund the promised work? |
Check unpaid invoices against the contract and delivered service. Assign the remaining work and customer response in the purchase agreement. Put any needed opening funds in the buyer's cash plan, alongside the cost of taking over the records and staff.
The plumbing M&A market guide and private-equity guide help compare buyer fit. They do not prove a reuse-service premium or current buyer interest. The business needs supported earnings and a workable plan for its actual sites.
What closing sequence makes the service handoff usable?
Set the acceptance conditions before choosing when the seller can leave. The buyer should know what it has bought, what it must do next, and who can lawfully do that work.
- List the acquired services and sites. Match installation, visits, checks, repairs, and reports to real fees and signed terms. Identify excluded work and promises that continue beyond the last invoice.
- Confirm the current approval route. Ask each authority about the permit holder, named manager, and planned deal. Keep adopted rules, pending filings, and proposals in separate records with clear dates.
- Secure staff and site access. Agree on actual duties, needed skills, licensed supervision where relevant, keys, and backup. Test that the buyer's team can reach the site and use the approved records.
- Match unfinished work to funds. Review missed reports, open faults, prepaid service, and unpaid bills. Assign who performs and pays for each item, then test the buyer's first-month cash needs.
- Check the handoff with a real file. Have retained staff locate one site's permit, current log, next task, and customer terms. Record what is accepted and what remains open before ending the seller's essential role.
A file copy is useful only if the team can use it. Complete the handoff when the buyer can find the next duty, supply the right person, and keep the required proof of delivery.
