Water Is the Quiet System Until It Isn't

Nobody books a site because of your water system. But everybody checks out early when the pressure drops to a trickle on a full Saturday, or when a boil notice goes up on the office door.

Water is one of those systems owners tend to manage by memory: which valve to close, which line breaks in a hard freeze, which pump is getting tired. When you sell, a buyer needs that memory on paper, plus proof the water is safe, legal, and able to handle a full park.

This page covers what buyers look for, the paperwork that matters, and how to get your water system ready.

Why Water Matters at Sale

Water touches almost every part of a buyer's decision.

Safety and legality. If your park has its own well and serves enough people, it may be regulated as a public water system. Under EPA rules, a public water system is generally one that serves at least 15 connections or at least 25 people for at least 60 days a year. Many campgrounds and RV parks fall into the "transient non-community" category. That can mean required testing, reporting, and sometimes a certified operator. Your state drinking water program decides how this applies to you.
Capacity. Can the well, pump, storage, and lines keep pressure up at peak? Low pressure at the far end of the park is a guest problem and a buyer red flag.
Cost. Water you pay for and do not recover lowers your net income. Leaks make it worse. (See our page on utilities and sub-metering.)
Septic. Water in equals wastewater out. High water use can push your septic system past its design.

Lenders and buyers treat an unknown water system as a risk. Unknown risks get priced high.

What Buyers and Lenders Will Scrutinize

Documents they will ask for

Water source: municipal connection, private well, or both.
If you have a well: well logs, pump age and size, storage tanks, treatment equipment (for example chlorination or UV), and any state system ID number.
Water testing results for the last several years, plus any violations, boil notices, or letters from the state.
Certified operator information if your system requires one.
Backflow prevention devices and their test records, where required.
Repair history: line breaks, pump replacements, tank work, with invoices.
Water bills if you are on municipal water, ideally 24 months.

Tests they will run

Water quality sampling, often bacteria and nitrates at a minimum.
Well yield or pump test to see whether the well can keep up.
Pressure checks at the near and far ends of the system, ideally under load.
Review of state records to see whether the system is in good standing.

Red flags that move price

No testing records, or gaps in required testing.
Past violations or boil notices with no clear fix.
A system that should be registered with the state but is not.
Low pressure at peak, especially at the far sites.
Old pumps, corroded tanks, or no backflow protection where required.
High winter water use that points to a leak.

What to Check, Fix, and Document

1. Find out what kind of system you have, legally

Call your state drinking water program and ask whether your park is a regulated public water system and what that requires. If you are already registered, ask for a copy of your file. If you should be registered and are not, talk to your attorney about how to address it before a buyer finds it.

2. Gather your test results

Pull every test result you have. If testing is required, make sure you are current. If it is not required, consider testing anyway before you sell, through a certified lab, so you have a clean result in hand.

3. Map the system

Sketch where the well, pump house, storage, main lines, shutoffs, and backflow devices are. Note pipe materials if you know them. Note trouble spots: lines that freeze, loops with low pressure, areas that flood.

4. Test pressure on a busy weekend

On a full weekend, check pressure at the closest and farthest sites at peak times (morning showers, evening). Write down readings and times. If the far end drops hard, a licensed plumber or water system pro can tell you whether it is the pump, the storage, the line size, or a leak.

5. Look for leaks

Compare winter and summer water use. If winter use stays high, you may have a leak. Find it, fix it, and keep the invoice. That one repair can help your water bill, your septic system, and your sale.

6. Service the equipment

Get your pump, pressure tank, treatment system, and backflow devices inspected and serviced by qualified pros. Keep every record. A buyer reads a service history as care.

Well log, pump details, storage, and treatment equipment listed
Certified operator information, if required
Backflow devices located and test records gathered
System map with shutoffs and trouble spots
Peak-weekend pressure readings at near and far sites
Winter vs. summer water use compared for leaks

24 months of water bills, if municipal

Common Mistakes

Assuming "it's just a well" means no rules. Depending on size and use, it may be a regulated system.
Skipping tests because the water "has always been fine." A buyer needs paper, not history.
Ignoring low pressure at the back of the park. Guests remember. Buyers measure.
Letting a leak run. It costs money twice: on the water and on the septic.
DIY work on regulated equipment. Use licensed pros, keep permits.

An Example

Illustrative example. Composite of situations we see; details and numbers changed.

An older couple ran a park on a private well. They tested the water when they bought the place years ago and occasionally after that. Pressure at the back loop got weak on holiday weekends, and they had learned to tell guests to shower early.

Before selling, they called their state drinking water program and learned their park was large enough to count as a regulated system, with testing requirements they had not been keeping up with. With their attorney's help, they got registered and current, had a certified lab test the water, and hired a water system pro, who found an undersized line feeding the back loop and a failing pressure tank.

They replaced the tank, kept a bid for the line upgrade, and put every record in a folder. When buyers looked, the water system was a known quantity with a clean recent test, not a mystery.
