Central Florida Water Providers by County: 2026 Homeowner Guide

Who Supplies Your Water, What It Costs, and What to Know

Water service in Central Florida isn’t run by one company or by county lines. Depending on the address, a home’s water may come from a city, a county utility, a regional authority, a private company regulated by the state, or a well in the backyard. The provider affects the bill, the deposit needed to open an account, and the watering rules.

Short version: Inside city limits, water usually comes from the city. In unincorporated areas, it’s usually the county utility. Osceola County is mostly served by Toho Water Authority, and the City of Cocoa supplies roughly a third of Brevard County, well beyond its own city limits. Lake County’s government doesn’t run a countywide system, so cities, private utilities, and private wells fill the gap. To confirm a specific address, check the seller’s water bill or the utility’s service area map. Government utilities set rates through their elected boards. Many private water companies are rate-regulated by the Florida Public Service Commission. Homes on private wells are the owner’s responsibility, and the Florida Department of Health recommends testing for bacteria and nitrate at least once a year. Water supply limits are pushing rates up, and drought orders currently limit lawn watering to once a week in Polk County and parts of Lake County.

How to find out who provides water to an address

A mailing address isn’t a reliable guide. Many homes with an “Orlando” or “Kissimmee” address sit outside city limits and are served by a county or regional utility. A few quick ways to check:

Ask the seller for a recent water bill. It shows the provider and often the sewer and garbage charges too. This is a reasonable request during the inspection period.
Use the utility’s service area map. Toho Water Authority and Brevard County both offer address lookups, and most county utility websites have one.
Check the property appraiser’s record. Whether a parcel is inside city limits usually points to the city utility.
Don’t assume sewer matches water. Some homes get water from one provider and sewer from another, and many rural homes have public water but a septic tank. See septic, sewer, and drainage.

Main water providers by county

County	Main public water providers	Good to know
Orange	Orange County Utilities (much of unincorporated Orange); OUC (City of Orlando and nearby areas); city utilities such as Winter Park, Apopka, Ocoee, and Winter Garden	An Orlando mailing address can mean OUC, Orange County Utilities, or a city. Check the bill or call the utility.
Seminole	Seminole County Utilities (unincorporated areas); cities including Sanford, Altamonte Springs, Casselberry, Lake Mary, Longwood, Oviedo, and Winter Springs	City limits and county service areas are closely mixed, so neighboring streets can have different providers.
Osceola	Toho Water Authority	Toho serves more than 160,000 customers in Kissimmee, St. Cloud, Poinciana, and unincorporated Osceola, plus parts of Polk and Orange. Kissimmee’s electric utility (KUA) is separate from its water provider.
Lake	City utilities including Clermont, Leesburg, Eustis, Tavares, Mount Dora, Groveland, Minneola, and Lady Lake; several private utilities	The county government doesn’t run a countywide water system. Rural homes are often on private wells.
Polk	Polk County Utilities (unincorporated areas); cities including Lakeland, Winter Haven, Bartow, Auburndale, Haines City, and Lake Wales	Water and sewer rates rise 6% a year through 2028, plus a surcharge to fund new water supplies. Northeast Polk near Poinciana may be served by Toho.
Volusia	Volusia County Utilities (parts of unincorporated Volusia); cities including Daytona Beach, DeLand, Deltona, Ormond Beach, Port Orange, and New Smyrna Beach	Volusia County Utilities has separate rate schedules for softened water in East Volusia and unsoftened water in West Volusia.
Brevard	City of Cocoa; Melbourne; Palm Bay; Titusville; Brevard County Utility Services (Mims and Barefoot Bay)	Cocoa serves more than 85,000 accounts, including Cocoa Beach, Cape Canaveral, Rockledge, Merritt Island, Viera, Suntree, and Port St. John.

Service areas change as cities annex land and utilities take over smaller systems. The lists above aren’t complete. Always confirm the provider for a specific address.

Government utilities vs. private water companies

Most Central Florida homes get water from a government utility: a city, a county, or an authority like Toho. These set their own rates through an elected board or commission, so rate changes go through public meetings. That’s the place to comment.

Some neighborhoods, especially older subdivisions and communities built away from city systems, are served by private, investor-owned water companies. The Florida Public Service Commission regulates 146 investor-owned water and wastewater utilities in 38 of Florida’s 67 counties. It approves their rates and handles customer complaints that the company doesn’t resolve. Buyers looking at a home served by a small private utility should ask about recent or pending rate cases, since a rate increase approved for a small system can be large.

Homes on private wells

Many rural homes in Lake, Polk, Volusia, Osceola, and Brevard counties draw water from a private well. No utility tests that water, so the owner is responsible for its safety. The Florida Department of Health recommends:

Testing for coliform bacteria and nitrate at least once a year.
Testing for lead about every three years.
Using a state-certified laboratory.

Florida doesn’t require well testing when a home is sold, so buyers should arrange it themselves during the inspection period. A well pump also needs electricity, so a power outage means no running water. See well water and water line permits, the home inspection checklist, and home backup generators.

Starting water service when buying a home

Water service usually isn’t transferred automatically at closing. The seller closes their account, and the buyer opens a new one. Orange County Utilities, for example, asks new customers to contact it at least three days before service is needed. Its home deposits are:

$41 for water only.
$135 for water and wastewater.
$19 for reclaimed water.

A $16 initiation fee applies during business hours. The deposit earns interest and is credited back after 12 months of on-time payments. Other utilities have their own deposit rules, and some accept a letter of good payment history from a previous utility instead.

A few things to check before closing:

Whether the home has a separate irrigation meter or reclaimed water for the lawn.
Whether the seller’s final meter reading is scheduled for the closing date.
Whether there are unpaid utility balances. These can follow the property in some situations, so ask the title company to confirm.

What’s on a water bill, and why rates are rising

A typical water bill has a fixed base charge and a usage charge that rises in tiers as use goes up, which mainly affects heavy lawn irrigation. Where the same utility provides sewer, the sewer charge is usually based on water use, often with a monthly cap. Some cities also put garbage, stormwater, or reclaimed water charges on the same bill.

Rates across the region are rising because the cheapest water source, the Upper Floridan aquifer, is near its sustainable limit. Polk County is an example:

The county says the upper aquifer was reaching its maximum safe withdrawals.
It’s turning to deeper, more expensive Lower Floridan water that needs extra treatment.
Water and wastewater rates rise 6% a year from October 2024 through 2028.
A usage surcharge rises $0.25 per 1,000 gallons each year to fund new supplies.

Other utilities are investing in reclaimed water, alternative supplies, and expanded treatment, and those costs show up in rates and connection fees.

For new construction, connection fees are a major line item. Polk County’s residential water connection fee reached $3,038 and its wastewater connection fee $6,168 as of October 1, 2025. See Florida impact fees by county, the new home fee calculator, and hidden costs of building a house in Florida.

Watering restrictions and the 2026 drought

Lawn irrigation rules are set by the regional water management district and can be tightened by the local utility or government. Under the St. Johns River Water Management District’s normal rules, which cover most of the region, homes may water two days a week during Daylight Saving Time and one day a week during standard time, never between 10 a.m. and 4 p.m. Days are based on whether the address is odd or even.

The 2026 drought brought stricter limits. The Southwest Florida Water Management District extended its Modified Phase III water shortage order through March 31, 2027. It covers all of Polk County and parts of Lake County, and its rules are:

Lawn watering one day a week, based on the last digit of the house number.
Sprinklers allowed only before 4 a.m. or after 8 p.m.

The St. Johns River district also has a Phase III Extreme Water Shortage in effect for portions of Lake County. Residential irrigation there is limited to one day a week and never between 8 a.m. and 6 p.m. Check the current rules for a specific address, since local utilities may be stricter. See Florida lawn watering restrictions and Florida-friendly landscaping.

Water quality: reports, hardness, and lead lines

Every community water system publishes an annual water quality report, also called a Consumer Confidence Report. It lists where the water comes from and the test results for regulated contaminants. Most utilities post these on their websites, and they’re worth reading before buying in a new area.

Central Florida’s groundwater flows through limestone, so tap water is often hard, which leaves spots on dishes and scale in water heaters. Volusia County Utilities notes that hard water isn’t a health concern and that buying a softener is an aesthetic choice. Softeners do add sodium, which matters for people on low-sodium diets. A chlorine smell, especially first thing in the morning, usually clears after running the tap.

Under federal lead and copper rules, utilities have inventoried service line materials, including the customer-owned line between the meter and the house. Polk County Utilities, for example, sent notices to customers whose line material was unknown and plans a replacement program for any lead lines found. Owners who get such a notice can ask the utility what it means for their property.

Boil water notices and hurricanes

When a water main breaks or pressure drops, utilities issue a precautionary boil water notice for the affected area until testing confirms the water is safe. These are common after storms and construction damage. Sign up for the utility’s alerts, and follow the notice until it’s officially lifted.

Before hurricane season, store at least a gallon of water per person per day for several days. Homes on wells should plan for no water during an outage. See the hurricane prep checklist and the Florida hurricane preparedness guide.

For the other utilities a new homeowner needs to set up, see electric providers, internet providers, and trash and recycling.

Frequently Asked Questions

Ask the seller for a recent water bill, or use the utility’s service area map. Homes inside city limits are usually served by the city, and unincorporated areas by the county utility. Osceola is mostly Toho Water Authority, and much of central Brevard is the City of Cocoa.

City, county, and authority utilities set their own rates through elected boards. The Florida Public Service Commission regulates the rates of about 146 private, investor-owned water and wastewater utilities in 38 counties.

The Florida Department of Health recommends testing for bacteria and nitrate at least once a year and for lead about every three years, using a state-certified lab. Florida doesn’t require testing when a home with a well is sold.

The Upper Floridan aquifer, the region’s main water source, is near its sustainable limit. Utilities are paying for deeper wells, extra treatment, reclaimed water, and other supplies. Polk County, for example, is raising water and sewer rates 6% a year through 2028.

The Southwest Florida Water Management District’s water shortage order limits lawn watering to one day a week, by the last digit of the house number, through March 31, 2027. Sprinklers may run only before 4 a.m. or after 8 p.m. It also covers parts of Lake County.

Yes. Hardness comes from minerals picked up as groundwater moves through limestone and isn’t a health concern. A softener is a matter of preference, though it adds sodium to the water.
