Buying Land in San Saba County, Texas

Groundwater: an old district managing a genuinely flawed aquifer

San Saba County's water picture is shaped by the Hickory Underground Water Conservation District No. 1, one of the older groundwater districts in Texas -- created by an order of the Texas Water Commission back on June 9, 1982, to conserve and manage the aquifers beneath what is now all of Mason County and most of McCulloch and San Saba Counties (with smaller slivers reaching into Concho, Menard, and Kimble Counties). That's a genuinely long regulatory history compared with districts created in just the last decade or two elsewhere in the state.

What makes this district's territory distinct isn't just its age -- it's the aquifer itself. The Hickory Sandstone Aquifer, which serves as a primary water source across San Saba, Mason, McCulloch, Concho, Menard, Kimble, and Gillespie Counties, carries naturally occurring radioactive material: radium-226, radium-228, gross alpha emitters, and radon, all decay products embedded in the aquifer's host rock. The issue is old and well studied -- the district commissioned a regional water-supply plan specifically to address radionuclide levels in Concho, McCulloch, and San Saba Counties, completed back in September 1991 -- and remains a live topic in regional groundwater planning today. This is a materially different situation from a county that simply lacks a groundwater district: San Saba County has an active district, but the resource it manages has a documented quality issue that a domestic well owner needs to understand before drilling. See our standalone well-water page for what this means specifically -- testing, treatment options, and how the district and TCEQ handle it.

Septic and subdivision: a regional office and a county rulebook

San Saba County does not appear to hold TCEQ authorized-agent status for on-site sewage facility (OSSF) permitting, which means applications for unincorporated county land most likely route through TCEQ Region 9, based in Waco (CORRECTED 2026-09, superseding an earlier framing that pointed to TCEQ's San Angelo-based Region 8, which does not serve San Saba County), rather than a dedicated county environmental health office. A licensed soil scientist must perform the required site evaluation before an application can move forward under the statewide 30 TAC Chapter 285 rules described on our Texas hub. Confirm current fees and timelines directly with the Region 9 office before budgeting a system.

On subdivision, San Saba County is not simply unregulated: it maintains its own written Subdivision Regulations, available at the county courthouse, that govern platting rural land within the county. Anyone buying already-subdivided acreage, or planning to split a larger tract, should pull the current version of those regulations directly from the county rather than assuming rural Texas land here is subdivision-rule-free.

Pecans, ranching, and agricultural valuation on the San Saba and Colorado Rivers

San Saba's identity as the self-proclaimed Pecan Capital of the World reflects a real agricultural base along the San Saba River, which itself flows roughly 140 miles before joining the Colorado River just east of the city of San Saba -- river frontage and native pecan bottomland are genuine, sought-after features of land here, alongside more typical Hill Country ranching, rolling pastureland, and native hardwood cover. As in most of rural Texas, a meaningful share of county acreage likely carries an agricultural or wildlife-management (1-d-1 open-space) valuation with the San Saba County Appraisal District rather than being taxed at full market value; qualifying generally requires a documented history of agricultural use, and a change in use after purchase can trigger a rollback tax recapturing prior tax savings. Confirm a specific parcel's current valuation status and any acreage or use requirements directly with the appraisal district before assuming a seller's exemption transfers automatically.
