How do we maintain the decorative fountain or water feature at our HOA entrance?

By OurHOA · General information · Revised October 25, 2026

How an HOA board maintains an entrance fountain or water feature: Legionella control, chlorine and cleaning, pump and GFCI checks, algae, drought rules and winter.

Part of the HOA board handbook: vendors, projects and upkeep.

The short answer

Treat the entrance fountain as a small water system, not a piece of landscaping. Run it every day, keep a measurable chlorine level in the water, check that level and the water temperature at least weekly, and clean it whenever you see slime, algae or cloudy water. Have a licensed electrician confirm the pump circuit has ground-fault protection, and test that protection monthly. Check your water utility's drought rules before summer, and drain the pump and pipes before a hard freeze if your climate gets one. Write all of it in a one-page log. Local health, electrical and water rules differ, and so do governing documents, so treat this guide as education, not legal or engineering advice.

Why a fountain needs a water plan

The risk most boards never hear about is Legionella, the bacteria behind Legionnaires' disease. The CDC lists decorative fountains and water features among the building water systems where it grows, and says people usually get sick by breathing in small droplets of mist. Its fountain guidance starts with a blunt line: all decorative fountains produce aerosols. Size is no protection. In 2005, a small fountain in a Rapid City, South Dakota restaurant lobby was linked to 18 cases, and the investigators wrote that it was the first time a small fountain without an obvious spray had been named as an outbreak source. Removing the fountain stopped the cases. An entrance fountain sits outdoors, often in full sun, and Legionella grows best between 77 and 113 degrees Fahrenheit, according to the CDC. Warm water that sits still, with sediment and slime on the basin walls, is the setup to avoid. The CDC also tells owners not to put fountains where people at higher risk of Legionnaires' disease spend time.

The weekly routine

The CDC's toolkit module on decorative fountains gives the routine, scaled to how much water the fountain holds. For a fountain over 25 gallons, which covers nearly every HOA entrance feature, it recommends at least 0.5 parts per million of free chlorine for at least 6 hours a day. Smaller tabletop-size features need 3 to 5 ppm for at least an hour a day. It says to check disinfectant level and water temperature at least weekly, to automate chlorine feed and monitoring if you can, to fill from a cold drinking-water supply, and to run the fountain at least daily rather than letting it sit idle. Cleaning for large fountains follows the test results, and any fountain gets cleaned whenever you see slime or debris. In practice, assign one volunteer or the landscape or pool vendor to a weekly stop: test free chlorine with a pool test kit, take the water temperature, look for algae, skim leaves, clear the pump intake, and write it down. A log line looks like this: "Oct 6, 8:10 a.m. Free chlorine 0.8 ppm, water 71 F, clear, intake cleaned. Initials." If the fountain has a timer, set it so the pump runs every day. Ask the vendor who installed it for the basin volume and the pump's manual, and keep both with the log.

When the water looks wrong

The CDC says to clean and disinfect right away when you see algae, slime, cloudy water, a foul smell or debris. Its steps for a fountain where nobody is sick: shut it off, raise free chlorine to 10 ppm and hold it for 1 hour, then drain, scrub every surface, clean or service the filter, refill with fresh water, and bring chlorine back to the routine level before turning the spray back on. If anyone in the neighborhood is diagnosed with Legionnaires' disease and the fountain could be the source, do not clean it first. Shut it off and call the county health department, which may want to sample the water before anything changes. The CDC's steps for that case go further: drain, scrub, replace the filter media, then hold at least 20 ppm for 10 hours before draining and refilling again, done in coordination with public health.

Pump, power and ground-fault protection

The CPSC's fact sheet on ground-fault circuit interrupters recommends them where electrical equipment is near water, says one can cut power on a leak as small as 0.006 amperes, and advises testing each one at least monthly and after a power failure. California's electrical safety orders put it plainly for fountains: all equipment over 15 volts used with a fountain must be protected by a GFCI. Rules in your state come through its adopted electrical code, so ask the electrician to confirm in writing that your fountain circuit meets it. That electrician needs a license. Texas Occupations Code section 1305.151 bars anyone from doing electrical work without a license issued under that chapter, and the homeowner exemption in section 1305.003 covers only a home the person owns and lives in, not common property. Florida Statutes section 489.531 prohibits electrical contracting without certification or registration. Colorado Revised Statutes section 12-115-109 requires electricians to be licensed, and section 12-115-120 covers permits. A board member can press the GFCI test button each month. Leave the rest to the electrician. Add the pump to the inspection list. Clear the intake screen every week, listen for grinding or rattling, and replace a pump that trips the GFCI repeatedly instead of resetting it over and over. Our guide on replacing an HOA pond fountain or aerator covers the bid and the wire run if you are buying new equipment.

Algae products and who may apply them

Most algaecides sold for fountains carry an EPA registration number, which means they are registered pesticides. The EPA says every pesticide label carries a legally enforceable line: it is a violation of federal law to use the product in a way that does not match its label. Buy a product labeled for fountains or ornamental water features, follow the dose for your basin volume. Who may apply it for pay depends on the state. Texas Agriculture Code chapter 76 ties licensing to restricted-use and state-limited-use products and regulated herbicides, including an aquatic pest control category. Florida Statutes section 487.031 likewise requires a certified applicator's license for restricted-use pesticides. Colorado is broader. Under Colorado Revised Statutes sections 35-10-103 and 35-10-105, anyone in the business of applying pesticides for hire needs a commercial applicator license. A Colorado association paying a vendor to treat the fountain should ask for that license number before the first visit.

Drought rules hit fountains early

Texas water suppliers must have drought contingency plans under 30 Texas Administrative Code section 288.20, and ornamental fountains are a common early target. Austin's plan requires ornamental fountains to recirculate at its first stage, bans those with more than a 4 inch spray or fall of water at stages 2 through 4 except to keep fish alive, and at its emergency stage bans running fountains or adding water to them. San Antonio Water System requires a variance for outdoor non-residential water features and caps daily run hours by drought stage for larger ones, and it asks everyone to shut water features off during drought stages. Call SAWS to confirm how it classifies a common-area fountain. Florida's water management districts can do the same. The Southwest Florida Water Management District's Phase III order, which ran from April into July 2026 in 11 counties and parts of others, limited purely decorative fountains to four hours a day, with the hours posted by the owner. The same order said no HOA could enforce deed restrictions or community standards that would require more water use. In Colorado, check your water provider's drought page each spring. Post the run hours on a small sign by the fountain when a limit applies, so owners know the dry basin is a rule, not neglect. Our guide on how an HOA should respond to drought watering restrictions covers the irrigation side.

Kids, mosquitoes and winter

A shallow basin at the entrance draws children. The CPSC says a child can drown in as little as 2 inches of water. Keep the pump intake covered and post a sign: "Decorative fountain. No wading or swimming. Water is chemically treated." San Diego County's environmental health department notes that ponds and fountains can breed mosquitoes and suggests keeping water moving, mosquitofish or a bacterial larvicide. A fountain left off for weeks with water in it needs one of those. In freezing climates, plan for winter before the first hard frost. An Iowa State University extension publication advises removing the pump, draining the plumbing and emptying containers so they do not crack when water freezes.

A year on the calendar and the usual mistakes

Spring: clean and disinfect, restart the pump, test the GFCI, confirm the timer runs daily, and read the water utility's drought page. Every week from restart to shutdown: chlorine, temperature, intake screen and the log. Monthly: GFCI test. Midsummer: plan on a full drain and scrub if the log shows slime or cloudy water. Fall: in freezing areas, drain, pull the pump and store it dry. Each year: ask the reserve specialist to list the pump, basin finish, lighting and any chlorinator as separate components. A motion the board can adopt: "Moved to adopt the entrance fountain water plan, to engage a licensed electrician to verify ground-fault protection on the fountain circuit at a cost not to exceed $400, and to direct the operations chair to keep a weekly chlorine and temperature log." Six mistakes come up again and again. Treating the fountain as decoration and never testing the water. Letting it sit full and still for a week to save power. Resetting a GFCI that keeps tripping instead of calling an electrician. Pouring in a landscaping product not labeled for fountains. Running the spray during a drought stage that bans it and drawing a utility fine. Leaving the pump in a basin that freezes solid in January.
