Can you actually drill a well on Hill Country land around Dripping Springs right now? For a meaningful share of parcels, the honest answer this month is no, or at least not without a fight. That single fact rearranges the entire due diligence sequence for anyone shopping acreage in western Hays County, and it is the piece almost nobody checks before they write an offer.
Most land buyers walk into an option period assuming the two big infrastructure questions, septic and water, are just a matter of hiring the right contractor. Around Dripping Springs, both questions run through public agencies with rules that change based on drought conditions and where exactly your parcel sits relative to the Edwards Aquifer. The price per acre gets all the attention. The permitting reality underneath it is what actually determines whether a tract is buildable on your timeline.
The 10-acre exemption everyone repeats, and the catch nobody mentions
Ask around and you will hear a version of this: buy 10 acres or more, and you are exempt from needing a septic permit. That is close to true, and also incomplete in a way that matters.
Texas rule 30 TAC 285.3 does allow an exemption from the standard septic permit for a single-family home on a tract of 10 acres or more, as long as it is the only dwelling on the tract, the system sits at least 100 feet from every property line, effluent stays on the property, and the system does not create a nuisance or pollute groundwater. Even then, the tract still needs a site evaluation and the system still has to meet state design standards. It is an exemption from the permit process, not from having a functioning, code-compliant system.
Here is the part that changes the math for a lot of Dripping Springs land: much of northern Hays County sits over the recharge zone or contributing zone of the Barton Springs segment of the Edwards Aquifer, and that boundary is specific to each parcel. If your 10-plus-acre tract falls inside that recharge zone, the exemption does not get you out from under 30 TAC 285.40, which layers on its own rules regardless of exemption status: a minimum lot size of at least one acre for homes built on lots platted after the rule took effect, no septic tank within 50 feet of a recharge feature, and no soil absorption field within 150 feet of one. Depending on the parcel, regulated construction may also require a Water Pollution Abatement Plan.
In practice, this means two ten-acre tracts a half mile apart can face completely different septic realities, one straightforward, one requiring an engineered system and additional state review, purely based on where the aquifer line falls. You will not see that difference on a listing sheet. You see it after a site evaluator walks the property, which is exactly why that evaluation belongs early in your option period, not at the end of it.
The well question, and why this is a bad month to assume the answer
Septic is the smaller surprise. The well question is the one worth raising before you ever get to inspections.
The Hays Trinity Groundwater Conservation District, which regulates groundwater across western Hays County including the Dripping Springs area, currently lists its own status as Emergency Drought Stage, its highest classification. The district is enforcing a 40 percent curtailment on groundwater pumping district-wide, and a 30 percent curtailment specifically within the Jacob's Well Groundwater Management Zone. Its posted guidance states plainly that no new permits for production or non-exempt well construction are being accepted until conditions improve.
That freeze applies to non-exempt uses, meaning anything beyond a standard single domestic well tied to production capacity limits the district defines. A straightforward domestic well for a single home may still clear that bar. But the district also requires well-construction notification confirmation before drilling starts, and separate guidance from local building resources notes the district does not accept new notifications for non-exempt uses during the more severe drought stages, which is exactly where the district sits today.
Even for parcels that clear the permitting hurdle, the physical water picture has gotten worse. A March 2026 report from Austin's NPR station, KUT, quoted Jared Thompson, owner of local well-servicing company The Well Doctor, describing water levels in the Wimberley and Dripping Springs area now sitting around 660 to 690 feet down, compared to roughly 500 feet after a healthy rain year in the past. The district told KUT that aquifer and river conditions have not been this poor in its more than 20-year history, including the 2011 drought, and that as of March 2026, 100 percent of its monitored wells were reading below their historic levels. The district's own drought outlook data puts the odds of enough rain to end the drought within six months at under 1 percent.
None of that means land near Dripping Springs is unbuildable. It means the well question needs a direct answer from the district and from a licensed driller before you get deep into a contract, not a general assumption that rural Texas land always comes with reliable groundwater.
| What buyers usually assume | What is actually true right now |
|---|---|
| 10+ acres means no septic rules to worry about | The permit exemption still requires a site evaluation, and recharge-zone parcels face extra setback and lot-size rules regardless |
| Drilling a well is a formality once you own the land | The groundwater district is not accepting new non-exempt well permits during the current Emergency Drought Stage |
| Water tables in the Hill Country are basically stable | District-monitored wells were uniformly below historic levels as of March 2026, with local servicers reporting depths well past historic norms |
| Power is available anywhere near a road | Extending electric service to raw land can run into five figures once you are past a modest free-footage allowance |
What it actually costs to bring power to raw land
The third infrastructure question buyers underweight is electricity. Rural cooperatives typically include a limited free-footage allowance, often in the range of 200 to 500 feet, before billing the property owner for the rest of the line extension. Beyond that allowance, running power to a homesite commonly costs somewhere between $5,000 and $25,000 or more per 1,000 feet, depending on whether the line goes overhead or underground and how much trenching, additional poles, or transformer work the site requires. On a tract where the buildable homesite sits well back from the nearest line, that number can move a project's budget meaningfully before a single foundation is poured.
The due diligence order that actually protects you
Given all of this, the sequence matters more than the checklist itself. Before you get attached to a specific tract:
- Confirm the parcel's status relative to the Edwards Aquifer recharge or contributing zone. This single fact changes your septic requirements even on tracts large enough to qualify for the standard exemption.
- Request a septic site evaluation and ask directly what system type the soil and aquifer status allow, and get a realistic cost and timeline, not a rough guess.
- Contact the Hays Trinity Groundwater Conservation District directly about your specific parcel and intended use before assuming a domestic well is a given. Ask what recent well logs from nearby properties show for depth and yield.
- Get a written line-extension estimate from the electric cooperative based on your actual homesite location, not the road frontage.
- Review access, easements, and whether the road serving the property is county-maintained or a private easement requiring a maintenance agreement.
- Ask the seller for their agricultural exemption history if the land carries a 1-d-1 valuation, since eligibility depends on documented use, not assumption.
Land listings across the Dripping Springs area this August average close to $82,000 per acre, based on nearly 2,000 acres currently on the market. That number tells you what the land costs. It tells you nothing about what it costs to make that land livable, and this year, the gap between those two numbers is wider than usual.
FAQ
If my land is 10 acres or more, do I still need a septic permit application? You may qualify for an exemption from the standard permit process, but you still need a site evaluation and a system that meets state design standards. If the parcel sits over the Edwards Aquifer recharge zone, additional setback and lot-size rules apply on top of the exemption, so confirm your parcel's aquifer status before assuming the exemption alone settles the question.
Can I still drill a well on land near Dripping Springs during the current drought stage? Domestic wells that meet the groundwater district's exemption criteria may still move forward, but the district is not accepting new permits for non-exempt uses during its current Emergency Drought Stage. Confirm your specific use and production needs with the district directly, and ask a licensed driller about recent depth and yield data for wells near the parcel.
How long does septic permitting actually take once I own the land? Hays County's process runs through an administrative review followed by a technical review by an inspector before an Authorization to Construct or Notice of Approval is issued. Timelines vary by application completeness, so budget for several weeks rather than days, and start the site evaluation during your option period rather than after closing.
Land purchases in this part of the Hill Country reward buyers who ask the infrastructure questions before the price questions.
