Most people worry about septic systems when it rains. But a long, hot Texas summer can cause trouble too.

Clay soil cracks

A lot of land around Lockhart, Kyle, and Bastrop has clay in the soil. When it dries out, it shrinks and cracks. That can move pipes. Joints can pull apart. A pipe that sat fine for years can start to leak.

Tree roots go looking for water

In a drought, tree roots go where the water is. Your septic lines have water. Roots can grow into small cracks and clog the pipe. If you have big trees close to the tank or the field, watch for slow drains.

Spray fields in summer

If you have an aerobic system, the spray heads put out treated water. That’s fine. But keep kids and pets off that area, and don’t use it for a garden. Make sure the heads aren’t spraying onto the house, a fence, or the driveway.

Simple things to do

  • Don’t plant new trees close to the tank or field
  • Don’t drive on the field, even when the ground looks hard
  • Spread out laundry so you don’t do it all in one day
  • Get a checkup if drains start to slow
