How permitting and review work in San Antonio
San Antonio Water System (SAWS) provides water and sewer service across most of the city. For a new tract, a SAWS Utility Service Agreement sets the infrastructure needed and reserves capacity. A Service Availability Letter shows the existing lines near a tract.
The City of San Antonio Development Services Department reviews plats, site plans and permits for projects in the city.
North Bexar County sits over parts of the Edwards Aquifer recharge, transition and contributing zones. In a regulated zone, TCEQ must approve an Edwards Aquifer protection plan before construction starts.
TCEQ also reviews public water and sewer designs and wastewater discharge permits. For sites with industrial wastewater, a 210E reclaimed water authorization can let the site reuse its treated water instead of discharging it.
Work in and near San Antonio
MES has finished civil site plans for three drive-up water kiosk sites in San Antonio. A fourth site, in Leon Valley, is in progress. These sites are part of a kiosk site program that spans seven states. Read more about our kiosk site planning.
Up I-35 in San Marcos, MES secured a 210E reuse authorization for a mixed-use data center development. See also our pages for New Braunfels.
Common questions
Do I need a SAWS Utility Service Agreement?
Often, yes, when a new tract needs new mains or reserved capacity. Many projects start with a Service Availability Letter to see what lines are already there.
Is my site over the Edwards Aquifer recharge zone?
Check the TCEQ Edwards Aquifer map viewer. If the site is in a regulated zone, plan for TCEQ review of a protection plan before construction.
