How-To Fix Your Failing Drain Field or Leach Field

On-site septic systems are not designed to last forever. Typically a system will last for 20 to 30 years, but with proper maintenance and attention, many years may be added to the life expectancy. Check for these possibilities:

     a. A leaking toilet or faucet can overload a system. Even a small drip can, over time, ruin a system.
     b. The addition of a bathroom, additional people in the household, washing too many loads of laundry, water softener discharging into a  household drain, any of these conditions can overload a drain field's designed capacity.

SOLUTION: Repair all leaks. When you think you have repaired all leaks, turn off all faucets in the house and check your water meter. Wait one hour and recheck your water meter. There should be no water use showing on the meter. In the case of a recent remodel, or bathroom addition you may have to add capacity by enlarging the drainage field. 

    a. Disposing of cooking grease, chemicals, feminine hygiene products, coffee grinds, cigarette butts, and overuse of garbage disposals can lead to contamination of drain field soil.

SOLUTION: If grease and organic solids are clogging the drainage pipes a professional septic maintenance company may be able to clear a blockage using a high-pressure jetting machine designed for this purpose. The process can then be followed with an application of chemicals (Septic Perc) and a quality biological formula (Mega Bio) to ensure the blockage is cleared from the soil.

Roots In Drain Field
    a. Trees and shrubs growing on or near the drain field can clog the field with roots.

SOLUTION: Roots can be cleared using chemical formulas commonly found in home supply stores. Roots and other blockages can be removed by mechanical means using a snake with a rooter-type head. A professional service company can inspect pipes, fitting, baffles, and the D-box to ensure they are intact.

Clay Soil - hard pan:
    a. This condition may be the least recognized common condition that can cause soil failure. Sodium bonding occurs when tiny particles of clay are exposed to sodium contained in wastewater or effluent. A chemical reaction takes place that bonds those small particles together to form hard-pan, a soil condition that stops water from being absorbed.

SOLUTION: Since the 1950s products using lime sulfur as an ingredient have been recognized as a solution to the problem of sodium bonding in clay soil. Our product SEPTIC PERC® has a neutral pH and a mild pleasant odor available HERE.

Overgrown Bio mat:
    a. The biological mat (bio-mat) is a layer of living anaerobic (without oxygen) microbes that form a tar-like substance lining the sides and bottom of the drainage trenches. It is a necessary part of the living system where viruses and pathogens are removed from the effluent before it passes through to the surrounding soil and, eventually, to the water table.
Aerobic (oxygen using) bacteria live in the soil surrounding the drainage trench. These air-breathing colonies keep the anaerobic bio-mat in check. When the soil floods the air-breathing colonies die off. Over time the bio-mat will increase to a point where it forms a waterproof layer that stops the flow of effluent to the surrounding soil.  

SOLUTION: Grease and organic solids clogging the drainage pipes may be cleared using a high-pressure jetting machine designed for this purpose. The process should be followed with an application of a high-quality biological formula (Mega Bio) to ensure the blockage is cleared from the field.


Seepage pits are more difficult to treat.
We recommend  for: Failing or sluggish cesspools and seepage pits: 
Apply Septic Perc - 6 Gallons: 3 gallons for first application then 1 gallon per week for 3 weeks applied through a toilet, sink drain or opening in the pit.
