- Shut off the water. Close the valve at your meter box, or turn off the well pump breaker if you are on a well. East Central SUD began its St. Hedwig expansion in 1971; check your bill, then call your provider about the meter.
- Make it safe and document it. Cut power to wet rooms from a dry spot, photograph the damage, then report the claim.
- Start drying within 24 to 48 hours. If your home is on septic and the drains back up after a long rain, the drain field may be saturated, so stop running water and have the tank checked before the cleanup starts.
St. Hedwig grew up near where Martinez Creek meets Cibolo Creek, and low crossings there flood fast. Never drive into water over a road.
