Project Setting:

Butte County
Site Address – 13953 Tangerine Court, Chico, CA 95973
The purpose of these calculations is to design a septic system for a 4-bedroom house.
Design Flow:
The system is designed for a 4-bedroom home.
Design Flow = 420 gpd (On-Site Wastewater Manual, Part 3, Chapter 3)
System Design:
Application Rate: The soils for the site consist of Clay Loam (Soil Group C). Given the nature
of the existing soils as shown from the soil mantle test and following the recommendations of
the Butte County On-Site Wastewater Manual Part 3, Table 1, an application rate of 0.6
gpd/ft2 was used for the existing soils.
Required absorption area = 420 gpd / 0.6 gpd/ft2 = 700 ft2 = 234 lf of 3’ wide trench.
Domestic water is supplied by a private well.
Proposed Septic Tank – 1,500 gallons
