How Drought Conditions Affect Your Septic Tank

Drought is a recurring challenge in Arizona, and its impact extends beyond water shortages and dry landscapes—it can also affect the health and performance of your septic system. Understanding these effects can help you take steps to protect your tank and drain field during extended dry spells.

Reduced Soil Moisture and Drain Field Function

Your septic system relies on soil in the drain field to filter and absorb wastewater. In prolonged drought, the soil becomes excessively dry and compacted, reducing its ability to absorb effluent effectively.

• Compacted soil slows down percolation rates.
• Cracked soil can allow untreated effluent to move too quickly, reducing filtration effectiveness.

Impact on Bacterial Activity

Beneficial bacteria in your septic tank and drain field require moisture to thrive. Drought conditions can lead to reduced bacterial activity, slowing the breakdown of solids and potentially leading to sludge buildup.

Increased Household Water Conservation

While conserving water is essential during a drought, extreme reductions in water flow can also affect septic performance. Too little water can prevent waste from moving efficiently through the system, increasing the risk of clogs.

• Avoid sudden, drastic reductions in daily water use—maintain steady, moderate flow.
• Space out water-heavy activities to keep the system active.

Potential for Damage from Shifting Soil

Extended drought can cause soil to shrink and shift, potentially putting stress on septic pipes and tanks. This movement may lead to cracks, leaks, or misaligned connections.

Best Practices for Septic Care During Drought

• Maintain a regular pumping schedule to prevent solids from overwhelming the drain field.
• Inspect your system for cracks, leaks, or signs of shifting after extended dry periods.
• Use water efficiently but consistently to keep the system functioning properly.
• Avoid planting deep-rooted vegetation over the drain field, as roots may seek out moisture from septic components.
