Septic System Basics

Every septic system is unique. A septic system is based upon site specific conditions, information, and site uses. A Septic System-or Onsite Wastewater Treatment System-consists of a septic tank and disposal field.


Septic Tank

The septic tank provides primary settling and treatment to occur. A typical residential septic tank is about 1500 gallons divided into two compartment. The solids are settled to the bottom and oil float on the surface. The middle layer provides a clear zone that flows through the baffle into the second 

compartment. The effluent flows from the second compartment out to the leach field.


Leach Field

All leach fields are different, but the purpose of all leach fields is to distribute the effluent to allow percolation into the soil. Leach fields distribute the effluent into the soil where the soil treats the effluent and allows for percolation.


Leach fields are sized based on the soil absorption, topography, and other site specific conditions. Call us today (925) 447-5200 to discuss the specifics for your site and speak with an engineer to discuss a plan of action for your onsite wastewater needs. We don't want you to waste your money and we will give you options for the most appropriate long term solution for your onsite wastewater needs.

Septic System Care

Even the best septic system needs to be maintained. Please call Acorn
Onsite, Inc. to speak to an Engineer about proper care.

Pumping
The usage and sizing of the septic tank will dictate the pumping interval. Generally a residential septic tank should be pumped every 3 to 5 years.

To Have Optimal Performance Follow These Guidelines:
Keep vehicles away from the system, DO NOT drive over tank or leach field.
Do not plant trees or shrubs near drain fields, roots will eventually clog the lines.
Dispose of household chemicals properly. Do not pour them down the drain.
Distribute laundry throughout the week to avoid overloading on one day.
Do not use the toilet as a trash can. Flush only toilet paper and waste down.
Monitor your tank yearly and have it pumped every 3 to 5 years.
Outlet Filters:
If installed, outlet filters should be cleaned yearly, simply hose off the built up solids. If an outlet filter is not installed please ask about the
benefits the next time the tank is pumped. If the filter has been damaged
or questions arise please call Acorn Onsite, Inc at (925) 447-5200.
