What is a septic system?

A septic system is a two part treatment and disposal system designed to condition untreated liquid household waste (sewage) so that it can be readily dispersed and percolated into the subsoil. Percolation through the soil accomplishes much of the final purification of the effluent, including the destruction of disease-producing bacteria.

What should I do to maintain my septic system?

By following a recommended pumping schedule, you can prolong the life of your leachfield.
