Know your system. Care for it well.
A simple look at what happens underground and the habits that can help protect it.
Two main parts, one important job.
A septic system treats household wastewater onsite. The septic tank holds wastewater while solids settle; the drainfield allows liquid effluent to receive further treatment in the soil.
Where separation starts
Solids settle as sludge, oils and grease float as scum, and liquid effluent remains between them. Inlet and outlet baffles help keep material where it belongs.
Where further treatment happens
Effluent moves into the absorption field. Naturally occurring microorganisms in the soil help break down contaminants before water reaches groundwater.
Prevention makes a difference
Routine pumping helps prevent solids from reaching the drainfield. The right interval depends on tank size, occupants, and how the system is used.
Protect what goes on below the surface.
What goes down your drains affects the naturally occurring bacteria in your tank and the health of the absorption field.

Avoid driving or parking on it, and keep trees and large shrubs away from the area where roots could cause damage.
Conserve water when practical and spread out water-heavy tasks to avoid overloading the system.
