A system that fits the lot, passes DEHQ, and is set to grade. We handle design coordination, permits, and the install—not just the excavation.
California does not treat a new or replacement OWTS as a weekend project. The county must approve the layout. The tank must be IAPMO-approved. The drainfield must match soil, slope, setbacks, and design flow.
A tank set wrong, a field in bad soil, or a skipped inspection becomes a failed system you cannot easily undo.
Solid State Septic installs residential and small commercial systems across San Diego County as a licensed C-42 contractor and DEHQ-approved OWTS installer.
Joseph Bartkowski covers San Diego County septic installation—installation permits, IAPMO-approved tanks, proper field placement, and DEHQ inspection holds.
Joseph Bartkowski explains when San Diego County owners should replace a failed septic system versus repair—LAMP trigger points, DEHQ authorization, and new-installation paths.
Yes. New systems and replacements require a DEHQ installation permit. We prepare and submit the package.
Yes, when the site can support an approved design. Slopes over 25 percent, shallow soil, or high groundwater often need an engineered or supplemental treatment system instead of a standard gravity field.
Yes, for small commercial properties within typical OWTS flow limits, subject to site and county review.
The field work is often days, not months. Permitting and any required percolation or engineering time are what stretch the calendar. Start that step early.
