Leaching Field Treatment Restoration

Leaching Field Treatment Restoration

The Drain field or Leach Field consists of a network of perforated pipes laid in gravel under the ground that allow the water to pass into the ground from the septic tank.  In most systems this pipe consist of PVC or the newer chamber style field lines that have a higher surface area.  Most septic systems work by gravity where the liquid wastewater from the house flows into the septic system (influent) and is discharged from the tank (effluent) to the absorption field or leach field.  The leach field is where the final treatment takes place.

The basic septic tank is designed to retain the solids and scum and prevent them from entering the leach field.  Most septic system provide a two to four day retention time. When the volume of the tank is reduced by the build up of solids and scum, the retention time is reduced allowing higher levels of the undigested sewage travel into the leach field.  This increases the demand on the leach field to break down the undigested material causing a film to form.  This biomass is an, ugly, black, anaerobic, layer that prevents the liquid from dispersing into the soil or evaporating through the surface.

Early signs of Leach Field Failure:

Odors or surfacing sewage (wet spots)

Gurgling sounds in plumbing system

Standing liquid over the drain field even during the dry months

Backup in plumbing during high water use (early signs of leach field problems)

Routine use Septic and Leach Field Products prevent the build up of the scum layer and the accumulation of sludge in your septic tank and are formulated to provide effective reduction of the fats oils grease, proteins, carbohydrates and cellulose in the wastewater reducing the load on the drain field.  Our leach field cleaner is formulated to break up the biomass layer that has formed in the leach field lines.

Leach Field Do’s and Don’ts

Know where your leach field is so it is easier to protect from trees or runoff

Keep heavy equipment off your leach field

Minimize water use or surges.  Leach fields do not have unlimited capacity

Divert downspouts away from leach field

Do not plant trees on or around your leach field
