Best Septic System Installation in San Diego, CA

How much does a new septic system cost in California?

A conventional septic system typically costs $15,000 to $30,000, depending on local permitting complexity, soil conditions, and labor costs. Alternative systems (mound systems, drip irrigation, FAST systems) required in certain areas cost even more.

What permits are needed for septic installation in California?

You need a Soil Evaluation approval from your county Environmental Health office and a Construction Permit before installation. All work must comply with the **California Health and Safety Code**, your **county OWTS ordinance**, and applicable **Title 22** / **Title 27** requirements where onsite systems interface with public health or solid waste rules. In some areas, additional regional commission approvals may be required. The permitting process typically takes 2-4 months.

How long does septic system installation take in California?

The physical installation usually takes 3-7 days for a conventional system. However, the entire process from initial soil testing through final inspection can take 3-6 months due to comprehensive permitting requirements.

What type of septic system do I need in California?

The system type is largely determined by your **county Environmental Health** department (Local Agency Management program) based on soil percolation results, lot size, setback distances, and proximity to wells or water bodies. Many properties in certain areas require alternative systems due to high water tables, poorly draining soils, or tight lot configurations.
