Installing an on-site wastewater treatment
system (septic system) within Sacramento County
The type of system your parcel will require depends primarily on where the
parcel is located. The most frequently installed system is the standard pit
system. This type of system is used in areas where it has been determined that
the system would be less likely to degrade groundwater quality, and the soil
conditions are such that effluent will be more readily absorbed into the pit
area. If your parcel is in an area where the water table is high, or soil
conditions are poor, a shallow leach field or deep trench type disposal field
may be required.
There are cases where it is not possible to install any of the above
systems. In these situations, an engineered or alternative system, designed by
a registered professional, will be required. Registered professionals include
Registered Environmental Health Specialists, Civil Engineers, or professional
Regardless of the system that is installed on your parcel, it is important
that the septic tank be approved for use in Sacramento County.
You may notice that the regulations for septic systems vary from county to
county. The regulations for Sacramento County are dictated by the geology of
the region where the system is installed.
