Septic Installation Services We Provide

We install a full range of onsite wastewater treatment systems for residential and commercial properties throughout San Diego County. Every installation is completed in compliance with current county codes and Department of Environmental Health (DEH) standards.

Conventional Septic System Installation

Traditional septic systems remain one of the most reliable and cost-effective solutions for properties not connected to a municipal sewer. We install both rock and pipe and chamber leach line systems, selecting the right design based on your property’s soil conditions, lot size, and local DEH requirements.

Advanced Treatment Unit (ATU) Installation

Some properties in San Diego County, particularly those near sensitive groundwater areas or on smaller lots, require an Advanced Treatment Unit instead of a conventional system. Septic Solutions Inc. is one of a select few certified ATU contractors in the region. We install all degrees and sizes of ATUs for both residential and commercial projects, handling permitting coordination and DEH compliance from start to finish.

Seepage Pits

Where soil and site conditions allow, seepage pits can be an effective alternative or supplement to a leach field. We assess your property and recommend the best solution based on perc test results and county requirements.

Septic Tank Installation

We install both plastic and concrete septic tanks sized appropriately for your property’s usage and system design. All tanks are installed to DEH specifications and inspected before backfill.

Our Installation Process

Every septic installation starts with a thorough evaluation of your property. Here’s what to expect when you work with Septic Solutions Inc.:
  • Site Assessment: We evaluate soil conditions, setbacks, topography, and existing infrastructure to determine the right system for your property
  • Permitting: We coordinate with San Diego County DEH on all required permits and approvals before any work begins
  • Excavation & Installation: Our experienced crew handles all excavation, tank placement, leach line layout, and system connections
  • Inspection & Commissioning: Once installed, the system is inspected for compliance and tested before the project is considered complete
  • Documentation: You receive all required documentation for your records and any future real estate transactions

Why San Diego County Properties Need the Right Installer

San Diego County has some of the most specific and strictly enforced onsite wastewater treatment regulations in California. Errors in system design, improper setbacks, or non-compliant materials can result in failed inspections, costly repairs, and significant delays. Working with a DEH certified contractor who knows local requirements isn’t just a good idea, it’s essential.
Septic Solutions Inc. has been navigating San Diego County’s permitting and compliance landscape for years. We know what the county requires, and we build systems that pass inspection the first time.
