Mississippi Heat: Staying Ahead of Summer Septic Issues

Quick Answer

Hattiesburg summers are famous for two things: oppressive heat and sudden thunderstorms. Both of these present unique challenges to your septic system. From accelerated bacterial growth to drought-related soil cracking, being a septic owner in the Pine Belt requires a summer strategy. This 1,000-word guide will help you keep your system cool and functional through the hottest months of the year.

When weeks pass without rain in July, South Mississippi's clay soil shrinks and cracks, which can allow oxygen into anaerobic drainfield areas or create channels for surface water to enter pipes. These cracks can disrupt the biological treatment in the drainfield and cause uneven absorption of effluent. Watering your lawn lightly during drought helps maintain soil moisture and prevents the worst cracking around your drainfield.

The "Drought Crack" Danger

When we go weeks without rain in July, the clay soil in South Mississippi shrinks and cracks. These cracks can allow oxygen to reach areas of your drainfield that should be anaerobic, or worse, they can create direct channels for surface water (and debris) to enter your pipes during the next storm. Keeping a healthy, mowed lawn over your septic area helps keep the soil moist and prevents this dangerous cracking.
