Post-Storm Water Well Safety

June 25, 2025

Storms in Houston aren't just a threat to your home—they're also a serious hazard to your private well. Heavy rainfall, flooding, and high winds can damage your well's physical components and introduce contaminants into your water supply. After any significant storm, taking the right steps to inspect and protect your well can prevent health risks and costly repairs down the line.

Inspect the Wellhead Immediately

Your first priority after a storm is a visual inspection of the wellhead. Look for signs of flooding around the well—if the wellhead was submerged, contaminants may have entered through the cap, casing joints, or electrical conduit. Check that the well cap is still securely attached and not cracked or displaced. If the cap is loose or damaged, call a professional immediately to assess whether shock chlorination is needed.

Check for Debris and Structural Damage

High winds can knock tree limbs, fencing, or other debris onto your wellhead. Remove any debris carefully and inspect the casing for dents, cracks, or displacement. If the casing appears bent or pulled from its original position, the seal between the casing and surrounding soil may be compromised. This creates a direct pathway for surface water and bacteria to enter your well. A compromised casing requires professional evaluation and may need repair or resealing.

Test Your Water After Flooding

If your well was flooded or you suspect contamination, do not drink the water until it's been tested. The Texas Commission on Environmental Quality recommends testing for total coliform and E. coli bacteria after any flooding event. At 77 Water Well Inc., we provide emergency water testing and shock chlorination services to ensure your water is safe before you resume normal use. The test results typically take 3 to 5 business days, so plan accordingly.

Prevent Future Storm Damage

Long-term storm protection starts with proper well construction and maintenance. Ensure your well cap is a vermin-proof, sanitary model—not a simple, unsealed cover. Verify that the casing extends at least 12 inches above ground and that the surrounding area slopes away from the wellhead. Annual inspections catch small problems before storms turn them into major failures. Consider adding a backup generator for your pump so you have water even if grid power is lost.
