Say you're comparing two listings, both addressed Purcellville, VA, both priced in the same range. One sells in three weeks with a bidding war. The other sits for six weeks even after a price cut. The finishes are comparable. The schools are the same. What's different is something neither listing sheet mentions: whether the house pulls water from a town main or from a well in the backyard.
That distinction, not square footage or granite, is doing more work in Purcellville's market right now than almost anything else, and this year gave a live demonstration of why.
Two Listings, One ZIP Code
Purcellville's incorporated town limits and the surrounding county land around it get lumped together under one name, but they behave like separate markets. Market tracking compiled this summer shows homes inside the town's official boundary selling in roughly 24 days, often with multiple offers and some contingencies waived, at an average price that had actually fallen by double digits from a year earlier. Homes across the broader Purcellville area, which includes the larger parcels just outside town limits, took closer to 42 days to sell over the same window, at a meaningfully higher average price that had climbed sharply year over year.
That's backwards from what you'd expect if this were one market. Usually higher prices come with more competition, not less. The explanation is structural. Inside town limits, a house connects to public water and sewer, a scarce and metered resource. Outside those limits, a house typically runs on private well and septic, unlimited by any town system but requiring its own due diligence. Buyers competing for the smaller, cheaper, in-town lots aren't really competing for square footage. They're competing for a water tap.
Why the Tap You Get Depends on a Reservoir Built in 1955
The town's water system draws from the J.T. Hirst Reservoir, built around 1955 and fed by three springs, Harris, Potts, and Cooper, along with groundwater from the Nature Park, Main Street, Mountain View, Jeffries, and Marsh well systems. The Virginia Department of Health caps the whole system's permitted yield at 974,000 gallons a day. The town's own figures from 2019 put average daily demand at roughly 560,000 gallons, with peak days reaching over 800,000. There isn't a lot of headroom in that math, and Purcellville found out how little this January.
On January 9, 2026, the town moved to mandatory water restrictions after conditions deteriorated from moderate to severe drought, cutting off outdoor watering, car washing, and requiring restaurants to serve water only on request. The town eased back to voluntary conservation on March 25, but even then it stayed at what the town's Drought Response and Contingency Ordinance classifies as Drought Warning, one notch above the calmer Watch designation, not a full return to normal.
Wastewater has its own ceiling. The Basham Simms Wastewater Facility, built in 2002 and upgraded to 1.5 million gallons a day of capacity in 2010, handles the town's roughly 35 miles of gravity sewer lines. The town is currently expanding its water treatment plant on Short Hill Road, a $3 million project phased through the FY2025-2029 Capital Improvement Program and already approved by the county Planning Commission. That's real added capacity coming, but it's incremental and years out, not a reset.
The County Just Proved the Point With a $261 Million Project
If you want to see how binding this constraint actually is, look at what Loudoun County itself decided to do a few miles outside town.
The Western Loudoun Recreation Complex, a roughly 96,000-square-foot recreation center and park planned for a 142-acre site at 36716 Main Street just outside Purcellville's boundary, carries an estimated cost of $261 million following the Board of Supervisors' design endorsement in March 2026. For more than a year, the county and town discussed connecting the facility to Purcellville's water and sewer system. On June 17, 2025, the Loudoun County Board of Supervisors consented to move forward without that connection. A public hookup would have required improvements to town infrastructure and could have added between $20 million and $30 million to the project's cost while pushing completion back as much as two years.
Instead, the county chose to build the complex on its own private well and wastewater system. Purcellville Town Manager Kwasi Fraser called the county's move "a matter of practical timing and project momentum," while adding that the town still sees future connection as an open door rather than a closed one. Either way, a government with a quarter-billion-dollar budget looked at what it would take to get on the town's system and decided drilling its own well was the faster, cheaper path. That tells you something about what an ordinary buyer is up against for a single residential tap.
Comparing Two Purcellville Addresses
| Inside Town Limits | Outside Town Limits (County) | |
|---|---|---|
| Utility source | Public water and sewer, permitted system capped at 974,000 gallons/day | Private well and septic, no town-imposed cap |
| Recent market behavior | Faster sales, more competition, lower average price this summer | Slower sales, less competition, higher average price this summer |
| Permitting authority | Town of Purcellville building department | Loudoun County Department of Building and Development |
| Rate exposure | Tied to town utility rate structure, currently under budget pressure | No town utility bill, but well/septic maintenance is the owner's responsibility |
| What to verify before offering | Utility account status, water/sewer availability fees | Well flow test, septic inspection, drain field location |
The utility rate line matters more than it looks. The town's rate consultant, Stantec, presented the council in 2025 with several multi-year scenarios, and under nearly all of them, both water and wastewater reserve funds dip well below policy targets before recovering, with average residential bills projected to climb by double-digit dollar amounts in some years depending on which scenario the council adopts. Buying into the town system means buying into that rate trajectory too, not just the lower purchase price.
The Pattern Isn't New
None of this is a recent quirk. A 1999 Washington Post account of the same towns described Purcellville's town manager at the time, Robert W. Lohr Jr., using annexation and guaranteed tap purchases as tools to manage growth around new water and wastewater plants, with the 147-acre Hirst Farm and the Kingsbridge subdivision, developed by Jim Jost and still one of the town's largest, at the center of those negotiations. The mechanism connecting utility capacity to who gets to build inside town limits has been running for a quarter century. It's just unusually visible this year because of the drought.
What This Means If You're Comparing Two Purcellville Addresses
Before you fall for a listing photo, ask the one question that actually separates these two markets: is this address inside the Town of Purcellville, on the public system, or is it served by a private well and septic field. That single fact tells you more about your likely closing timeline, your future utility bill, and how much competition you'll face than almost any other line on the disclosure form.
If you're looking at an in-town property, factor in the utility rate scenarios the town itself is modeling, not just the current bill. If you're looking at a county property just outside the line, budget time and money for a proper well flow test and septic evaluation rather than assuming the absence of a monthly water bill means the absence of infrastructure risk.
A Few Questions Worth Asking Before You Write an Offer
How do I find out if a specific listing is on town water or a private well? Ask the listing agent directly, or check with the Town of Purcellville's utility service department to confirm whether the address has an active town water account. Properties outside the boundary will show a well and septic system on record with Loudoun County instead.
Will the Short Hill Road plant expansion open up more in-town supply? It adds capacity, but the project is phased through 2029 as part of the town's capital improvement plan. It eases the ceiling gradually. It doesn't remove it, and it isn't the same thing as new lots becoming available.
Does a longer time on market mean county-area well and septic homes are a weaker choice? Not necessarily. Those properties tend to be larger, carry higher price points, and require more specialized diligence, all of which naturally slows a sale compared to a smaller in-town lot with public utilities. Slower isn't the same as weaker demand.
Whether you're chasing a tight in-town lot or weighing acreage on a well, the utility question is the one worth answering first, before the inspection period, before the appraisal, before you fall for the kitchen.
