Before You Count Bedrooms in Hampstead, Find Out Where the Wastewater Goes

"What is the dwelling's sewage disposal system?" That is question C4 on North Carolina's Residential Property and Owners' Association Disclosure Statement, the form most sellers must complete and sign by the time a buyer makes an offer. A few limited exemptions apply, such as new construction that has never been occupied. The current version, REC 4.22, revised in July 2026, lists several septic types, a "community system," "Connected to City/County System," "City/County system available" and "Other."

In Hampstead, that one question carries more weight than it does in most places. Houses here may connect to Pluris Hampstead, LLC, which is a private wastewater utility regulated by the North Carolina Utilities Commission. Others use Pender County Utilities, a neighborhood plant, or a septic system in the yard. Each one prices sewer service differently. Each one also ties what a house can support to bedrooms in its own way. So in Hampstead, the bedroom count on a listing and the monthly cost of owning the home both depend on the wastewater arrangement behind the address.

The checkbox that doesn't quite fit

None of the C4 options names a privately owned, state-regulated utility. A Pluris customer isn't on a city or county system. Depending on how the seller reads the form, the house may be marked "community system" or "Other." That isn't anyone's mistake. The form is written for the whole state, and Hampstead's setup is unusual.

Pluris operates a plant off Blake Farm Boulevard in Scotts Hill, and Port City Daily describes its service area as Hampstead and Scotts Hill. Its footprint is still growing. In November 2025 the Utilities Commission granted Pluris franchises for Southwater Village and for Indigo at Abbey Preserve. The Southwater Village order recorded 13 residential customers at the time, with 81 planned. Some neighborhoods aren't on Pluris at all. A Castle Bay resident told Port City Daily that Castle Bay has its own wastewater plant.

We could not find a public, address-by-address map showing which Hampstead homes are on Pluris, county sewer or septic. The most reliable way to find out is to ask for the provider's name and a recent bill.

Same bedroom, different bill

How a home is charged for wastewater depends on the provider. Here is how the published numbers compare as of September 2026:

The Pluris figure is a flat rate. The tariff charges a residential unit $85.05 a month whatever its water use, which works out to $1,020.60 a year. A household that is away half the year pays the same as a full house. For a second-home buyer, that is a fixed line in the budget that doesn't drop when the house is empty.

The rate is also fairly new. Pluris filed a general rate case, Docket W-1305 Sub 38, on September 3, 2024. It asked to raise the residential rate from $82.50 to $91.63, and the Commission approved $85.05. The new rate didn't start until regulators confirmed that Pluris's expanded membrane bioreactor plant was in service. The Commission's order dated July 25, 2025 made it effective for service from that date on. The franchises for Southwater Village and Indigo at Abbey Preserve use the same $85.05 rate and $3,600 connection fee.

Water is a separate bill, and it has moved too. Pender County Utilities' monthly water availability fee for a 3/4-inch meter went from $32.50 in fiscal 2025–26 to $36.75 in fiscal 2026–27. Usage is billed on top at $7.50 per 1,000 gallons up to 10,000 gallons. The county's adopted budget describes the 13.2% increase as helping to fund the proposed Hampstead Membrane Water Treatment Plant and other capital projects. That plant would treat drinking water, not wastewater. The county said in December 2025 that it was still in permitting. Before you compare two Hampstead homes on carrying cost, add up the water and sewer lines for each one. Those two bills come from different providers and follow different rate schedules.

The fourth bedroom question

All three arrangements put a cost or a limit on bedrooms. That matters if you're buying a three-bedroom house with plans to add a fourth, or paying for a four-bedroom house whose fourth room was added later.

On Pluris, the connection fee goes up by $1,200 for each bedroom past three. Pluris defines a single-family equivalent as a detached home with three or fewer bedrooms. On septic, the limit is written on the permit, and REC 4.22 asks the seller how many bedrooms the permit allows. "No Records Available" is one of the answers the form permits. The same question asks when the system was last pumped. Pender County requires a septic suitability evaluation and a construction authorization before a system is installed, and a final inspection before a new home can be occupied.

To check the permit yourself, you'll need to send a request. Pender County's septic permit information request asks for the property address, subdivision and lot, parcel ID, the name on the permit or the current owner, and the year the house was built. The form lists Hampstead Environmental Health at 15060 US-17, Hampstead, NC 28443, phone (910) 270-5000. You can also send the request through the county's online public records portal, which names the Health Department as the contact for septic permit information. Neither route is an instant lookup. Send the request early in due diligence, not in the last week.

North Carolina's on-site wastewater statute does not require a septic inspection for every home sale. State statute defines an on-site system inspection as one requested by a lender, a prospective buyer or another party as a condition of sale, and it requires the inspector to be certified. The NC Real Estate Commission's due diligence guidance advises buyers to have well and septic systems inspected during that period. If you don't ask for one, it doesn't happen.

What the Hoover Road decision does and doesn't settle

Pluris wants to build a second plant on a 32-acre tract off Hoover Road in Topsail Township. Port City Daily reports the plant would serve about 5,500 customers in Hampstead and Scotts Hill. The company says the Blake Farm plant is built for 1 million gallons per day and runs at about 60% of that. State rules require design work on added capacity to start once a plant reaches 80%, and construction to start at 90%. Pluris says it doesn't have room at Blake Farm to build out its full permitted 3 million gallons per day, so it wants to split future capacity between two sites.

The exact split has been described in more than one way. The formal county application proposes 2 million gallons per day at Blake Farm and 1 million at Hoover Road, for 3 million total. At the August 4 Planning Board meeting, a Pluris design engineer said the company had applied to change the Blake Farm permit so the maximum there would be 1.5 million gallons per day. The board then recommended the rezoning. Castle Bay residents, whose neighborhood is about 3,000 feet from the site, hired an attorney to raise concerns about public notice and environmental protection.

County Commissioners had both matters on the agenda for September 21. According to StarNews, the meeting ended without any action because two commissioners were absent and one seat is vacant, which left the board short of a quorum. As of today, the rezoning has not been decided. Even if it's approved, Pluris estimates construction would start in 2028 and service in 2029.

For a buyer looking at an existing home, the vote doesn't change this year's bill or the bedroom limit. It affects where new Pluris connections can come from later in the decade. That matters most for lots and new subdivisions in Hampstead and Scotts Hill that haven't connected yet.

What to get in writing during due diligence

1. The name of the wastewater provider, plus a recent bill or account statement.
2. For Pluris homes, whether the connection fee was paid for the current bedroom count, especially if any rooms were added after the house was built.
3. For septic homes, the permit and the number of bedrooms it allows, requested from Hampstead Environmental Health, along with the date the tank was last pumped.
4. A septic inspection by a certified inspector, set as part of the purchase timeline.
5. The water source and its provider, billed separately from sewer.

A few questions buyers ask us

Is a Pluris home on public sewer? It's connected to a central sewer system run by a private company, and the North Carolina Utilities Commission sets its rates. It isn't a city or county system, which is why the disclosure form's checkboxes don't match it exactly.

Does a lower water bill lower the Pluris sewer bill? No. The residential rate is a flat $85.05 per unit per month, the tariff in effect since July 25, 2025.

Could the Hoover Road plant affect a home I buy this fall? Not your current service. The rezoning is still undecided after the September 21 meeting, and Pluris projects service from the new plant in 2029 at the earliest.

When we list a Hampstead home, we start by confirming the provider, the permitted bedroom count and the service history, before photography or pricing.
