Well or City Water? How to Tell What Your Pasco Neighborhood Has (2026)

There is a thread on the Land O' Lakes Nextdoor page that restarts every few months. Somebody asks whether the street is on county water, four neighbors answer confidently, and at least two are wrong about their own house. That is not a knock on the neighbors. Well or city water in Pasco County is genuinely not obvious from the curb.

Quick summary: If your monthly bill charges you for water and there is a meter box at your curb, your Pasco County home is on city water. If you have a pressure tank, a pump switch and no water charge, you are on a private well. Plenty of Pasco County homes have both, because the house runs on county water while a separate irrigation well feeds the sprinklers. Florida has no drinking water record on file for about one in four built parcels in Pasco County, so looking it up does not always work.

How do I know if my Pasco County home is on a well or city water?

You are on city water if a utility bills you for gallons used and there is a meter box at the curb. You are on a private well if the property has a pressure tank and a pump switch and no bill charges you for water. In most Pasco County homes those two checks agree.

The four fastest tells, side by side

What to check	Points to city water	Points to a private well
The monthly bill	A line charging for gallons used	No water charge at all
At the curb	A utility meter box in the ground	Nothing in the ground
Garage, shed or side yard	A softener at most, no pump	A pressure tank and a pump switch
During a power cut	Water keeps running	Water stops when the pump stops

Bottom line: The pressure tank is the most reliable tell, because a home on county water has no reason to own one.

That last row is the free test nobody thinks of. City water pressure comes from the utility, so an outage does not touch it, while well pressure comes from an electric pump and the tap goes quiet within a minute. If your water has ever stopped in a storm while the neighbors showered, you have your answer.

Why is this so hard to look up in Pasco County?

It is hard because the state's own records have no answer for every address. The Florida Department of Health mapped Pasco County for its Water Management Inventory in 2023 and found no drinking water source on file for 52,235 built parcels, which is 23.1 percent of the county.

The same Pasco County inventory puts 121,280 parcels on public water as a known fact and 34,996 more as likely, against 15,548 known private wells and 1,993 likely. The gaps are not spread evenly. They cluster on older acreage and in the pockets between subdivisions, where a water main stopped at the last house on the paved road.

Odessa is the clearest case in our Tampa Bay service area, which is why the Odessa water guide is written for first-time well owners rather than utility customers.

What are the five checks that settle it?

Five checks settle it: read the bill line by line, look for a meter box at the curb, look for a pressure tank, check the county's provider map, and search well permit records for your street. Any two that agree is usually enough.

Start with the bill, and read the line items rather than the logo at the top. A Pasco County Utilities bill is not proof of county water on its own, because it can cover sewer, reclaimed water and trash without covering drinking water. Look for a charge tied to gallons.

Then walk to the curb. A utility water meter sits in a rectangular box set into the ground near the property line, under a lid you can lift. A private well leaves nothing there.

Then find the pressure tank. It is a steel or fiberglass tank between a beer keg and a water heater in size, usually blue, grey or tan, sitting in a garage, well shed or carport with a small grey pressure switch and a gauge plumbed beside it. That tank holds pressure made by a pump, so if you have one, you have a well.

Then check the county's own map. Pasco County Utilities tells people to do this before they open an account: "Before opening an account with Pasco County Utilities please use Pasco Mapper as a resource to first determine your provider information." Search Pasco Mapper by address and read the service area on that parcel.

Then search the well records. The Southwest Florida Water Management District keeps a searchable file of every well construction permit it has issued, filterable to Pasco County. A permit on your street means a well was drilled there, and the record lists the depth, the casing depth and what the well was permitted for.

Can a Pasco County home have both city water and a private well?

A Pasco County home can absolutely have both, and thousands do. The house runs on Pasco County Utilities water while a separate well feeds the irrigation system. That split is why a driveway and fence go rust orange on a street where nobody's drinking water stains anything.

The Halvorsens moved down from Minnesota and bought a 1990s house on an acre north of Land O' Lakes. They had a Pasco County Utilities bill, so they assumed county water, and could not work out why the driveway and the bottom of the fence had gone orange while the kitchen sink looked fine.

The answer sat in the side yard behind an oleander: a pressure tank feeding nothing but the sprinkler zones. The house was on county water. The lawn was on iron-heavy well water. A softener would not have touched those stains, because it would sit on the wrong side of the problem. That is a common find on Land O' Lakes water treatment jobs.

What changes once you know which one you have?

The whole treatment question changes. City water in Pasco County arrives disinfected, so you are usually treating hardness and a chloramine taste. Private well water arrives straight out of the Floridan Aquifer, so you may be treating iron, sulfur, manganese, tannins and hardness at once.

What each supply means for treatment

Your supply	What you are usually treating	Where your numbers come from
Pasco County Utilities	Hardness, chloramine taste and odor	Your system's annual water quality report
Private well	Iron, sulfur, manganese, tannins, hardness	A test at your own tap
County water plus an irrigation well	Both, on separate plumbing	The report for the house, a test for the well

Pasco County Utilities disinfects with chloramine, which the county describes as adding a small amount of ammonia, less than one part per million, to the water along with chlorine. That is why plain carbon underperforms here and why catalytic carbon belongs in a dual-media system for city water. A private well carries no chloramine at all, so a well house gets iron and sulfur removal instead.

Pasco County Utilities is also not one water system. Its 2025 water quality reports cover ten separate public systems, each with its own permit number, from Pasco County Regional down to Pine Breeze and Sunburst Hills. The report that describes your water is the one for your system, not a county average.

What should I do first if the checks say private well?

Test it. The Florida Department of Health recommends every private well owner test for bacteria and nitrate at least once a year, and for lead about every three years, and says a county health department sample usually runs 20 to 30 dollars.

Two things surprise people here. Florida has no requirement for well sampling when a private home is sold, so a closing can go through with nobody looking at the water. And Pasco County is not one of the twelve Florida counties whose health departments enforce local rules on new or repaired wells, while Hillsborough County is. Neighbors a mile apart across that line have different obligations the day a pump gets replaced.

If you want to know what is in your well rather than what is typical, that is what a test is for. We put what we keep finding into what is really in Pasco County well water, and the rest of the county sits in our local water guides.

The most useful thing I can tell a new Pasco County homeowner is this. The county is not one water story, it is two, and which one you live in was decided by where a water main happened to stop thirty years ago.

Frequently asked questions

How do I know if I have a well or city water in Pasco County?

Look for a water charge on your monthly bill and a meter box at the curb, which together mean city water. A pressure tank with a pump switch and no water charge means a private well. If those two checks disagree, trust the pressure tank.

Can a house in Pasco County have city water and a well at the same time?

Many Pasco County homes have both, with county water plumbed to the house and a separate well feeding the irrigation system. That split is the usual reason a driveway stains orange while indoor fixtures stay clean.

Does Florida require a well water test when a Pasco County home is sold?

The Florida Department of Health states that Florida has no requirement for well sampling when private homes are sold. The department still recommends testing for coliform bacteria, nitrate and lead, and some loan programs require a certified test anyway.

Who can tell me whether Pasco County Utilities serves my address?

Pasco County Utilities directs people to Pasco Mapper to determine their provider before opening an account, and its customer service line is 727-847-8131 on weekdays. The county also runs walk-in service centers in Land O' Lakes, New Port Richey and Dade City.

Does being on a well or city water change what treatment I need?

It changes it completely. Pasco County city water usually needs softening plus catalytic carbon for the chloramine, while private well water usually needs iron and sulfur removal first and softening second.

Why does my neighbor have county water when I am on a private well?

Water mains follow development rather than property lines, so a main can stop at the last platted lot on a street and leave the acreage behind it on private wells. That is common across Pasco County.
