"Example: A residence with 15,000 gallons of water usage in a quarter would be billed $309.00 for that quarter bill." That line comes from the Town of Manchester's public notice on Ordinances 274 and 275, approved May 12, 2026. Buyers comparing Carroll County towns usually start with listing prices. In Manchester, the quarterly water bill tells you more about why the town's housing supply looks the way it does.
Manchester runs its own water system. The capacity of that system, the cost of treating it, and a planning decision the town has signaled together limit how many new homes can go up inside town limits. For someone buying here, that means two things: existing homes make up most of the in-town supply, and every in-town owner shares the cost of maintaining a small, self-contained system.
The FY27 rates took effect July 1, 2026. Three charges apply every quarter no matter how much water a household uses. Usage charges are added on top of those.
| Charge | FY27 rate, effective July 1, 2026 |
|---|---|
| Water unit charge | $42.00 per quarter |
| Sewer unit charge | $57.00 per quarter |
| Bay Restoration Fee | $15.00 per quarter |
| Water usage | $4.62 per 1,000 gallons |
| PFAS water charge | $0.46 per 1,000 gallons |
| Sewer usage | $7.92 per 1,000 gallons |
The town's example works out exactly. The fixed charges total $114 a quarter. Each 1,000 gallons used then costs $13.00 across water, PFAS, and sewer, so 15,000 gallons adds $195, for a total of $309. Sewer is the largest per-gallon charge on the bill, well above the water rate.
Rates have also moved quickly. At its May 13, 2025 meeting, the Town Council took up Ordinance 265, which raised the water rate from $3.85 to $4.62 per 1,000 gallons, and Ordinance 266, which raised the sewer rate from $6.00 to $7.20. The FY26 rate notice split that $4.62 into $4.20 for water usage plus a separate $0.42 PFAS charge. Under FY27, those two charges together come to $5.08 per 1,000 gallons, and the FY27 sewer rate of $7.92 means sewer usage has risen about 32 percent in two fiscal years. If you're comparing a Manchester home on town water with a home elsewhere, ask the seller for recent quarterly bills, just as you would ask for utility history on any other property.
The 2023 Carroll County Water & Sewer Master Plan describes Manchester's system as town-operated. It serves only the area inside the corporate boundary and draws on 19 wells and Hillside Spring, with 12 pumping stations and 581,000 gallons per day in average daily appropriations. The Maryland Department of the Environment approved that plan on September 22, 2023.
Not every source is producing right now. The county's draft Water Resource Element, dated as of October 30, 2025, says the Patricia Court well was temporarily offline pending PFAS treatment. The Walnut Street spring was also offline, though the draft says it could return with suitable treatment.
The near-term project list in the county's Fall 2024 Master Plan amendment shows how little new capacity is on the way. Refurbishing the Walnut Street spring carries a potential capacity of 0.025 million gallons per day. PFAS mitigation at the Manchester Farms, Park Ridge, and Patricia Court sites is listed with zero added capacity. New wells near Walnut Street and Bachman Road appear only as a future, 10-year project with capacity still to be determined. Most of the money going into the system right now goes toward treating and protecting the water the town already has. Very little of it adds supply.
The question of whether Manchester has room to grow gets two different answers depending on which county document you read.
The gap comes from method. The WRE builds drought conditions and long-range service areas into its buildout math. At the town's Planning and Zoning meeting on July 15, 2025, a county planner described "a large discrepancy in the numbers" and said she would revise the Manchester wording to explain how the figures differ.
The same July 2025 minutes record the decision that shapes Manchester's housing supply most. The county planner would add action items "to show that the Town's next comp plan update will be reducing the municipal growth area which reduces the buildable lot inventory and in turn will decrease the need to look for additional water sources."
Manchester is planning to need less water by allowing fewer future lots, and that does more to keep new construction scarce than any market force. The draft WRE identifies 498 additional residential lots in Manchester's planned water service area, based on 2022 zoning. A smaller growth area would shrink that inventory.
Projects that do move forward face a slow, case-by-case process. Manchester reviews water appropriations, pump capacity, and peak and drought factors before approving a development. Under the 2024 amended plan text, once adequate capacity is found, a fee of $15,000 per equivalent dwelling unit is due with each building-permit application. Water adequacy has to be shown at each stage of Planning Commission approval. The county also keeps a general policy of denying allocations where service would exceed a jurisdiction's adequate-facilities threshold. None of this amounts to a moratorium. The published materials describe review and allocation, and they do not describe a freeze.
Sewer sets a ceiling of its own. The town's treatment plant is designed for 500,000 gallons per day. The draft WRE estimates 65,452 gallons per day of sewer capacity remaining at full buildout, which works out to roughly 260 dwelling units. Sewer allocation goes first-come, first-served after site-plan or subdivision approval, at 375 gallons per day per dwelling unit. The master plan's priority sewer projects, inflow and infiltration repairs and an Enhanced Nutrient Removal upgrade, are both listed as adding zero capacity.
Recent changes have been small. The Fall 2024 amendment moved five single-family units from long-range to existing water service and added 1,250 gallons per day of projected demand. The town's builder market reflects that. Castlefield, Ward Communities' 55+ villa community in Manchester, is now listed as no longer available, and Ryan Homes' current Carroll County community list shows nothing in Manchester.
Countywide, the September 2026 Maryland REALTORS housing statistics show Carroll County with 151 closed sales, down 3.2 percent from September 2025. The median sale price was $474,350, up 2.6 percent. Active listings stood at 366, or 2.2 months of inventory, and median days on market rose to 19 from 11 a year earlier. Bright MLS reported the same core figures for September 2026.
Those are county figures, and the county is cooling a little. Homes are taking longer to sell and buyers have more listings to look at than a year ago. Inside Manchester's town limits, though, supply depends less on builders than in towns with room to expand. When new construction is limited by water allocation, a shrinking growth area, and a $15,000-per-unit fee, the homes already standing make up nearly the entire in-town market. Buyers who want a home on town water in Manchester are shopping a resale market. Sellers there are competing mostly with other existing homes, not with model homes offering builder incentives.
The PFAS work shows where the money goes. The town and its engineers have moved through these steps:
The town has not published a construction cost or schedule for the treatment facility itself. On the sewer side, MDE's June 2025 draft Clean Water Project Priority List estimates the Manchester treatment plant's ENR upgrade at $51,951,256 in total, with $41,443,062 requested from MDE and planned milestones running from December 2025 to June 2027. That figure comes from a draft funding list and may not match the final cost. The May 2026 minutes note that MDE and CDM Smith were still working through design discrepancies on the ENR project. Projects of that size help explain why the sewer rate rose in two straight budgets.
Is there a moratorium on new water connections in Manchester? The current county and town planning documents describe case-by-case capacity review and allocation. They do not describe a blanket freeze.
Does every Manchester-area home use town water? The town system serves only the area inside the corporate boundary, according to the 2023 Master Plan. A Manchester mailing address alone does not tell you whether a home is on town water, so confirm service for the specific property.
What is the PFAS charge on the bill? It's a separate usage charge of $0.46 per 1,000 gallons under the FY27 rates. It funds the town's PFAS work while treatment design continues.
