Why Is Houston County Building a New Water Plant on Highway 127?

Houston County commissioners awarded an $11.4 million construction contract on September 22, 2026 for a new drinking water treatment plant on Highway 127 near the Moody Road intersection, in the Kathleen area of unincorporated Houston County. The plant will add up to 2.5 million gallons a day of treated water to the county system and is scheduled to be running by early 2028, according to the county minutes and 41NBC. The contract went to Parrish Construction Group on a 570-day build schedule.

The county said the project is paid for with its recently adopted water connection fees and water capital funds, not with a new rate increase. The county's utilities director told 41NBC that the system is stretched on peak demand days with what it has now, and that the plant is needed to ensure an adequate supply for current customers and for future growth. Peak summer days reached about 28 million gallons in 2024 and about 24 million gallons in 2026.

The project was first approved in January 2026 as a roughly $15 million plan funded from the county's water capital fund, with 41NBC reporting that planning work began in early 2024. It is a fresh drinking water plant drawing from wells, not a sewer or wastewater facility. The county has about 175,000 residents, up more than 11,000 since 2020, and county officials have reported daily water demand rising from about 11 million gallons in January 2022 to about 15 million gallons in January 2025.

Houston County Water System Timeline, 2022 to 2029

The gap between the two peak figures is worth reading carefully. Demand on the hottest days ran lower in 2026 than in 2024, which the county has not attributed to any single cause, and the county issued a Level 1 drought declaration with voluntary water restrictions in April 2026. The plant is sized against the long-run trend in connections and population rather than against any one summer.

Who Is on Houston County Water, and Who Is Not

Does a New Water Plant Change What My Home Is Worth in Kathleen or Bonaire?

A water treatment plant does not change a home's appraised value on its own. What it changes is the county's capacity to approve new connections, which is the practical limit on how many new subdivisions can be built in the unincorporated parts of the county. Water availability is one of the items a developer has to show before a residential plat is approved, and a county that is adding 2.5 million gallons a day of capacity is a county expecting more rooftops in Kathleen, Bonaire and the areas around Perry and Warner Robins.

What I tell owners on county water is that this is a supply story, and supply cuts both ways. More capacity means more new construction will be approved near you over the next several years, which can mean more competition from builders when you list, and it can also mean the amenities and retail that follow rooftops. The sellers who come out ahead are the ones who know what has been approved around their address before a buyer's agent brings it up. That is a question I can answer for a specific neighborhood.

What Should I Ask About Water Before Buying New Construction in Houston County?

Ask three things. First, which provider serves the address, because county and city rate schedules differ and the answer follows the parcel rather than the postal city. Second, whether the water connection fee has already been paid and by whom, because the county's standard fee is $2,500 in 2026 and is scheduled to pass $6,000 by 2029, and a builder's price may or may not include it. Third, whether the lot has a confirmed water source and meter, which matters most on acreage and infill lots outside a platted subdivision.

My advice to buyers is to treat water the way they treat the school zone: a fixed fact about the address that should be known before the offer, not discovered after. For a buyer looking at the Highway 127 corridor between Perry and Kathleen, this plant is a signal that the county plans to keep approving growth out that way through 2028 and beyond, and that the view from a new lot today may include more neighbors in five years. Neither of those is a reason to wait. They are reasons to know what is planned around a specific address, which is a conversation I have with buyers before we write an offer.

Frequently Asked Questions

Where is Houston County's new water treatment plant?

The plant is being built on Highway 127 near the intersection with Moody Road, in unincorporated Houston County in the Kathleen area between Kathleen and Perry. It sits on the county side of the line rather than inside any city limits, which means it feeds the Houston County water system rather than the City of Perry or City of Warner Robins systems. The site was chosen as part of planning work that 41NBC reported began in early 2024.

How much does the new Houston County water plant cost?

The construction contract awarded on September 22, 2026 is $11,428,520.71 to Parrish Construction Group, according to the county minutes, which 41NBC rounded to $11 million. When commissioners first approved the project in January 2026, the planning estimate reported by 41NBC was about $15 million. The awarded contract came in below that planning figure, though total project cost can include engineering, land and equipment outside the construction contract.

When will the Highway 127 water plant be finished?

The county has said the plant should be in service in early 2028. The contract carries a 570-day construction schedule from award, which lines up with that target. Construction timelines for water facilities can move with weather, materials and permitting, so the early 2028 date should be treated as the county's plan rather than a guarantee.

How much water will the new plant add to Houston County's system?

Up to 2.5 million gallons a day of treated drinking water, according to the county and 41NBC. For scale, the county has reported average daily demand of about 15 million gallons as of January 2025 and peak summer days of about 24 million gallons in 2026 and 28 million gallons in 2024. The plant is an addition to existing capacity, not a replacement for an existing facility.

Is the Highway 127 plant a sewer or wastewater plant?

No. It is a fresh drinking water treatment plant that draws from wells, treats the water and sends it into the county distribution system. The county made that distinction publicly when the project was approved in January 2026. Wastewater in Houston County is handled separately, and the City of Perry has its own large wastewater plant project that is not connected to this one.

Why does Houston County need another water plant?

The county's utilities director told 41NBC that on peak demand days the system is stretched with what it has now and that the plant is needed to ensure an adequate supply for current customers and for the future. The county has about 175,000 residents, up more than 11,000 since 2020, and officials have reported daily demand climbing from about 11 million gallons in January 2022 to about 15 million gallons in January 2025. New subdivisions in Kathleen, Bonaire and the unincorporated areas around Perry and Warner Robins all connect to the same county system.

Does the new plant serve Warner Robins, Perry or Centerville?

Not directly. Warner Robins, Perry and Centerville each operate their own municipal water utilities with separate rates and separate supply, and neighboring Byron is served by its city system. The county plant serves Houston County water customers, which means households in Bonaire, Kathleen and the unincorporated county areas surrounding the cities. Which provider serves a specific address is determined by the parcel, so a city mailing address is not proof of city water.

Will the new water plant raise my Houston County water bill?

The county has said the plant is funded by its recently approved water connection fees and water capital funds. That is separate from the three-year water rate plan the county adopted in 2025, which the county tied to operating losses on the water system and rising operating costs for existing customers. Connection fees are paid when a new meter is set, so the plant's cost is designed to fall on new construction rather than on existing customers' monthly rates, though future rate decisions remain up to the county.

What are Houston County water connection fees and who pays them?

A water connection fee is a one-time charge paid when a new service is connected to the county system, typically by the builder or developer and usually passed through in the price of a new home or lot. Houston County's standard one-inch meter connection fee is $2,500 in 2026 and is scheduled to rise to more than $6,000 by 2029, with larger commercial and multifamily connections increasing proportionally. Existing customers do not pay connection fees; they apply to new service only.

Does water capacity decide where new subdivisions get built in Houston County?

It is one of the main limits. A developer can own land and have it zoned for houses and still be unable to build if there is no confirmed water supply and meter capacity to serve the lots. When a county expands its treatment capacity in a specific part of the system, it is making room for connections that have not been built yet. That is why the location of this plant on the Highway 127 corridor is a signal about where the county expects growth between Perry and Kathleen.

How fast is Houston County growing?

41NBC reported the county's population at about 175,000 residents, up more than 11,000 since 2020, when it covered the plant approval in January 2026. The county's own demand figures tell the same story from the utility side, with reported daily water use rising about 36 percent between January 2022 and January 2025. Both the new plant and the rising connection fee schedule are the county's response to that pace.

Is Houston County under water restrictions?

The county issued a Level 1 drought declaration with voluntary water restrictions in April 2026, which asks customers to limit outdoor watering rather than imposing fines. Peak summer days in 2026 ran about 24 million gallons, below the roughly 28 million gallon peaks of 2024. Current restriction status is posted by the county and should be confirmed with Houston County Utilities, since drought declarations change with conditions.
