Septic Preservation Services

Septic Systems are great when they're working!

Septic systems do an amazing job of returning liquids to the soil for purification. They can continue to operate effectively for over twenty years with proper use and regular tank pumping. But when they fail, the conditions they create are dangerous! These Can include:

Toxic sewage surfacing in yard

Health hazards to children and pets

Noxious odors over large areas

Polluted streams and ponds

Sewage back-up in buildings

Contaminated wills

Breeding areas for mosquitoes


Septic system failure is practically inevitable.

The White Knight Microbial Inoculator/Generator

We do in the septic tank what nature does in the woods!

More info

Septic system failures are the result of many processes, most of which are out of sight and occurring unnoticed. These processes include:

Soil clogging by organic material that is flushed out of the septic tank

Soil clogging by chemicals from water conditioners and laundry detergents

Hydrogen sulfide deterioration of concrete components

Tree and shrub root intrusion that clogs pipes

Excessive surface water flowing into the septic tank and/or the leach field

Excessive water from building drains

Restricted liquid flow due to improper designand/or installation

Restricted liquid flow due to structural damage to the leach field

Nearly all processes that lead to failure can be eliminated.
