In Hampstead, Your Water Bill Depends on Who Owns the Pipes

Last spring, a Hampstead couple started watering their lawn and received a $463 bill for drinking water, wastewater and irrigation. The homeowner told WECT that before moving, it had never occurred to him to ask what the average water bill was.

Most buyers comparing homes in Hampstead don't ask either. The question matters more here than in most of the Cape Fear region because water and sewer service is split among several providers. A county utility, a state-regulated private water and sewer company and a private sewer-only utility each bill differently. The provider that serves a street decides whether sewer is a flat monthly fee or a charge that rises with every gallon. A listing sheet shows taxes and HOA dues, but it doesn't show this.

The same water, priced by three providers

These are the residential rates in effect as buyers tour homes this November. They come from the North Carolina Utilities Commission's June 30, 2026 tariff order for Carolina Water Service of North Carolina, the Commission's July 25, 2025 order for Pluris Hampstead, and Pender County Utilities' FY2026–27 schedule.

Carolina Water Service lists Belvedere Plantation and Olde Pointe among its service areas. A Harbor Village resident who spoke at a 2024 Carolina Water Service customer meeting in Hampstead identified himself as a customer, according to WHQR. The company's statewide tariff lists separate rates for a handful of named service areas elsewhere in the state. None of the Hampstead communities is among them, so the uniform rates above apply.

The table explains why a buyer can't compare two Hampstead homes on list price, HOA dues and taxes alone. The fourth carrying cost depends on which pipes the house connects to.

Where sewer is billed by the gallon, usage raises two charges

Carolina Water Service bills residential sewer on a metered basis: a $66.24 base plus $20.14 for every 1,000 gallons. Its water costs $19.25 per 1,000 gallons on top of the $34.85 base. That means each 1,000 gallons billed on both lines costs $39.39.

Here is how that adds up at the current rates when the same gallons appear on both lines:

• 5,000 gallons in a month: $131.10 for water plus $166.94 for sewer, about $298 in total.
• 10,000 gallons in a month: $227.35 for water plus $267.64 for sewer, about $495 in total.

Doubling the gallons raises the bill by about $197. In summer, a lawn, a garden bed or a pool top-off can easily add that much water. How outdoor water counts toward the sewer charge at a given address is a question for the utility.

The company told WECT in June 2026 that its average residential water and wastewater bill is about $212 a month. It said it had recently upgraded its meters and that it can't set or change rates without approval from the state Utilities Commission. The same report noted that the Cape Fear Public Utility Authority charges $5.16 per 1,000 gallons. The homeowner estimated that his bill would have been closer to $200 in Wilmington for the same usage.

Rates aren't a new concern in these communities. In February 2024, Belvedere Plantation and Olde Point residents filled the Topsail Middle School cafeteria for a meeting with Carolina Water Service about water quality and pricing, WHQR reported.

Under per-gallon rates, a leak or an irrigation timer stuck in the wrong season shows up on the bill quickly. The tariff also lists irrigation meter installation at actual cost. A buyer who plans to keep a green lawn should ask the utility directly how a separate irrigation meter would be billed at that address.

Flat-rate sewer moves the risk somewhere else

Pluris Hampstead, LLC is a private utility that provides only wastewater service. It charges residential customers a flat $85.05 a month per unit under the Utilities Commission order of July 25, 2025. In its most recent rate case, Pluris reported about 2,468 residential flat-rate customers and 93 metered commercial customers in Pender County. Its 2024 annual report describes its service area as the Hampstead area from Wylies Branch to Bridgewater.

With a flat rate, watering the lawn doesn't raise the sewer charge. The sewer line stays the same whether a household uses 3,000 gallons or 12,000. For comparison, Pender County Utilities water at 5,000 gallons comes to $74.25 a month at the FY2026–27 rates. The county's usage charge rises from $7.50 to $11.00 per 1,000 gallons only above 10,000 gallons a month.

The county also offers a separate irrigation meter. It carries a $5,382 setup fee covering the water system development fee, tap and inspection, plus a $36.75 monthly base and $8.00 per 1,000 gallons. That setup fee is real money for a lawn. On a county account, though, irrigation has a defined, published price.

Pluris's capacity is also expanding. According to Port City Daily, the company's plant off Blake Farm Boulevard in Scotts Hill is built to treat 1 million gallons a day under a permit for 3 million. Pluris told the Pender County Planning Board in July 2026 that the plant was running at about 60% of its built capacity. The company proposed a second, roughly 5,000-square-foot plant on a 32-acre parcel off Hoover Road to serve the Hampstead and Scotts Hill areas. It estimated construction would begin in 2028 and service in 2029.

Pender County commissioners approved the new 32-acre facility in a 3–2 vote, the StarNews reported on October 15. At the July hearing, a Castle Bay resident told the planning board that Castle Bay has its own wastewater treatment plant and would not be served by the Pluris facility. Even neighboring communities along U.S. 17 can sit on entirely different sewer systems.

The rate schedule keeps changing after closing

Today's rates already tell a buyer a lot, and the scheduled increases tell them more.

The Carolina Water Service order approved three rate years at once. The figures in the table cover service from April 1, 2026 through March 31, 2027. Rate Year 2 takes effect April 1, 2027, and Rate Year 3 takes effect April 1, 2028. A buyer closing this winter will see the first scheduled change within months.

On the county side, Pender County's FY2026–27 budget built in a 13.2% water rate increase as part of a phased plan to fund its membrane water treatment plant and other capital projects. For new connections, the county's schedule lists system development fees of $3,432 for water and $7,107 for sewer on a 3/4-inch meter. Those fees matter mostly to anyone building on a lot rather than buying an existing home.

Pluris's flat rate is set by the Utilities Commission, just as Carolina Water Service's rates are. The 2025 order raised it from the earlier $82.50 to $85.05.

Questions to settle before you write an offer

These rates come from published regulatory orders and county schedules. This post is general information, not legal or financial advice, so confirm the specifics for any address with the utility itself and with your own advisors.

1. Ask who provides water and who provides sewer, as two separate questions. In Hampstead, one company may supply the water while a different provider handles the sewer, or the home may use a private septic system.
2. Ask the seller for twelve months of bills. A year of statements covers both summer irrigation and winter use. An average quoted in a single month can hide either.
3. Check for an irrigation meter. On a county account, an existing irrigation meter means someone has already paid the $5,382 setup fee. On a Carolina Water Service account, ask how irrigation water is billed for sewer.
4. If the home is on septic, request its permit records. Pender County Environmental Health accepts septic permit information requests and has a Hampstead office at 15060 US-17, reachable at (910) 270-5000.

A few direct answers

Is a high Hampstead water bill a sign that something is wrong with the house? Not necessarily. Under usage-billed sewer at the current Carolina Water Service rates, 10,000 gallons in a month comes to about $495 with nothing broken. At $19.25 per 1,000 gallons for water alone, a leak adds up quickly. Comparing bills across seasons helps separate normal use from a problem.

Does the new Hoover Road plant change anything for buyers this year? Not right away. Pluris projected construction in 2028 and service in 2029. Today, its customers are served by the Blake Farm Boulevard plant.

Who sets these rates? Rates for Carolina Water Service and Pluris are approved by the North Carolina Utilities Commission. Pender County Utilities rates are set through the county budget.

If you're selling in Belvedere Plantation, Olde Pointe, Harbor Village or anywhere along the U.S. 17 corridor, having a year of utility bills ready can answer a buyer's question before it becomes a concern at the negotiating table.
