Drain Field Failure


Cause of
Septic System Failure

The drain field accepts and processes wastewater from the septic tank before it returns to natural aquifers below the earth's surface. Drain field failure is when absorption stops causing septic system failure.

Regular check-ups, tank pump-outs, and maintenance treatments with Septic Perc can keep your system running smoothly. Our Combo Shock Treatment can restore drainage even in clay soil.

A flooded septic drain field can form an overgrown bio-mat which prevents water absorption. Industrial-strength Mega Bio can digest grease and sludge and restore an overgrown bio-mat.
The bio-mat is kept in check through the aerobic bacteria in the drain field. Flooded drain fields kill the bacteria, and the bio-mat prevents wastewater absorption.

Crushed Pipes

Vehicles and equipment driving over the drain field can crush drainpipes and compress the gravel fill they are set in, causing total septic system failure.


This may be the most common cause of septic system failure. Septic tanks must be pumped every 3 - 5 years. If a tank is not pumped, sludge accumulation can cause an overgrowth of the bio-mat. Additionally, grease and fats that form a floating layer in the septic tank can then flow to the drain field where, over time, they will clog soil pores.

Sodium Bonding

Sodium in wastewater causes soil containing clay to turn into hardpan due to sodium bonding. Hardpan will stop the flow of water causing septic system failure. Septic Perc can solve this problem.

Root Intrusion

Intrusive tree roots can interfere with the septic drain field and grow into the drain field soil and pipes. Do not plant trees or bushes on or near the drain field.
