Austin Project Spotlights
Lake Travis Hillside Estate
Challenge: Navigating steep, rocky topography and strict setbacks on a Lake Travis waterfront lot.
Solution: Designed a custom multi-stage tiered aerobic treatment system with reinforced gravity dispersal areas.
Central Austin Small-Lot Infill
Challenge: Engineered septic design for a .15-acre lot with significant space constraints and heritage oak trees.
Solution: Implemented a high-efficiency secondary treatment unit with reduced setback variance approval.
Hays County Ranchette
Challenge: Variable clay soil depths and tight limestone formations typical of the Dripping Springs area.
Solution: Engineered a precision Low Pressure Dosing (LPD) system with custom-capped absorption beds.
Austin Regulatory Compliance
Navigating the complex OSSF (On-Site Sewage Facility) landscape in Central Texas requires an engineered approach that prioritizes long-term soil health and TCEQ compliance. Under Texas law, any new septic installation must be preceded by a professional soil morphological classification and a site-specific engineered design before construction permits are issued.
Travis County Standards
Permitting in Austin and surrounding Travis County often falls under the jurisdiction of the LCRA or Travis County TNR, particularly near Lake Travis. Designs must meet strict setbacks from the Highland Lakes and the Edwards Aquifer recharge zones to protect regional water quality.
Hays & Williamson Permitting
We work directly with county environmental health departments in Dripping Springs and Georgetown to facilitate Chapter 285 compliance. Our engineers ensure all soil tests and site plans align with specific local jurisdictional requirements for Hays and Williamson counties.
