Greenville County water providers: who supplies your water

By the GVL Plumbers editorial team · Published Oct 31, 2026 · 8 min read · Filed under Water, bills & pressure

If you've just moved here, or you're buying a house, figuring out your Greenville County water provider is one of those small chores that turns out to matter. It decides who you call when the water goes off at 10 p.m., what you pay per gallon, whose water quality report applies to you, and how a leak gets handled on the bill. It also isn't always obvious. Two houses on either side of a road near Greer can be on different systems, and a Fountain Inn address can be billed by a utility from another county.

This guide covers who supplies water where, how to find out which one you have, who to call for an outage, a main break or a billing question, and what changes for you depending on the answer. For who owns which section of pipe once you know your provider, see our guide to who owns the water and sewer line.

Which Greenville County water provider serves your area?

Greenville Water

Greenville Water is the big one. It draws from Table Rock Reservoir and North Saluda Reservoir in the northern part of the county, and from Lake Keowee, and treats the water at its Stovall and Adkins plants. Its 2025 water quality report says it delivers through 3,275 miles of pipeline. It serves the City of Greenville and most of the surrounding county, including Taylors, Mauldin, Simpsonville, Five Forks, Berea, Wade Hampton and much of Piedmont. Travelers Rest's water comes from Greenville Water under a contract with the city. Greenville Water also took over the Pelzer and West Pelzer systems in Anderson County in recent years.

Greer CPW

The Greer Commission of Public Works runs its own water system, fed by Lake Cunningham and Lake Robinson on the South Tyger River, with a treatment plant next to Lake Cunningham. It manages more than 24,500 water meters across about 400 miles of water lines, in Greenville and Spartanburg counties. Its service area covers the City of Greer and runs roughly north along Highway 14 to the treatment plant and Highway 101 toward North Rutherford Road and Highway 290, and south along Highway 101 toward Robinson Road and Abner Creek. Greer CPW publishes a Service Availability Map on its water page so you can check an address. It also provides electricity, natural gas and wastewater service, so some Greer households get all of it on one bill.

Some streets with Greer addresses, including parts of the Pelham Road side, are on Greenville Water instead. Our Greer plumbing page has more on that boundary.

Smaller systems near the county's edges

• Blue Ridge Rural Water Company is a member-owned rural water provider based in the Greer area of northern Greenville County. ReWa lists it among the water agencies whose customers it bills for sewer treatment.
• The Marietta area has its own water district. Greenville County's tax records list a separate Marietta Water levy for some Slater-Marietta tax districts, and the special purpose district (Marietta Water, Fire, Sewer and Sanitation District) is listed at 3001 Geer Highway in Marietta.
• Laurens County Water and Sewer Commission serves some addresses on the Laurens County side around Fountain Inn. See our Fountain Inn page.
• Powdersville Water serves parts of neighboring Anderson County, and some addresses near Piedmont may be billed by it. See our Piedmont page.

We looked for evidence that Startex-Jackson-Wellford-Duncan Water District serves Greenville County addresses and didn't find any; its service area is in western Spartanburg County. If you live near the county line by Duncan or Lyman, check your bill.

Private wells

Homes in the rural north (around Tigerville, Gowensville, Cleveland and the foothills) and on some rural edges elsewhere are often on private wells. No utility is responsible for that water. You own the well, the pump, the tank and the testing. Our Travelers Rest page covers well and septic basics for the north county.

How to find out which provider you have

1. Look at the water bill. The utility's name is at the top. If you get a single bill with electricity and water, you're almost certainly on Greer CPW.
2. No water bill at all? You're probably on a private well. Look for a well house, a wellhead in the yard, or a pressure tank in the crawlspace, garage or utility room.
3. Buying a house? Ask the seller for a recent water bill. The listing may say "public water" without naming the provider.
4. Check the utility's map. Greer CPW has a Service Availability Map. For other systems, call with the address.
5. Look at the meter box. Lids are sometimes marked with the utility's name or initials, but don't rely on it alone.

Sewer is a separate question. A Greenville Water customer might have sewer from MetroConnects, the City of Greenville, Mauldin, Simpsonville or Fountain Inn, or a septic tank. Greenville Water bills on behalf of ReWa, MetroConnects and those four cities, so the sewer charges usually show up on the same bill even though a different agency provides the service.

Who to call for outages, breaks and billing

A good rule: if water is coming up from the street or the meter box, or your neighbors are out too, call the utility. If the problem starts on the house side of the meter, it's yours, and a plumber fixes it. Greenville Water, for example, maintains the line to the outlet side of the meter; the line from there to the house is the customer's. For a sewage backup in a MetroConnects area, call MetroConnects first; our sewer backup guide explains why.

What differs for you, depending on the provider

A few practical consequences. On Greenville Water, you almost certainly don't need a water softener; our water softener guide has the numbers. On Greer CPW, the tiered rate means a leak pushes you into the higher price per gallon faster. If you're comparing bills between neighborhoods, remember the sewer charges are often bigger than the water charges; our high water bill guide breaks that down.

On a well, everything is on you

No one tests a private well for you, and there's no number to call when the pressure drops. SC DES runs a private well testing program (a $20 coliform bacteria test, with a minerals and metals analysis also available), and the kit comes from a DES regional office or health department. When the power goes out, a well pump stops with it. And when something breaks, it's a plumber or well contractor, not a utility crew. Most well homes also have a septic tank; see our post on septic tank pumping in Greenville County.

Starting service when you move

Greenville Water handles start, stop and move requests online or by phone and asks for identity information, including a Social Security number, to start service. Greer CPW has its own start and stop service page. If the house you're buying has a well, ask for the most recent water test, the age of the pump and pressure tank, and when the septic tank was last pumped. Those answers are worth more than any utility account number.
