New construction and repair work travel different DEHQ paths—even when both involve a tank and a field. Joseph Bartkowski, founder of Solid State Septic in Ramona, compares new versus repair OWTS permit pathways in San Diego County under the Final 2025 LAMP so owners start in the right queue.
Calling every job a “repair” to skip design review is a fast way to lose authorization. The comparison below follows County DEHQ septic program materials, the Final 2025 LAMP, State Water Board OWTS Policy, and EPA septic education—high-level permitting orientation, not legal advice.
When DEHQ Treats Work as a New OWTS
New dwellings, major expansions, and systems that replace failed dispersal with a redesign typically follow new-system permitting: soil evaluation, design, fees, and construction inspections. Joseph Bartkowski tells owners to expect LAMP-current standards—not a grandfathered sketch from decades ago.
- Plan for site evaluation and a design package sized to current bedroom count and soils.
- Budget County review time before construction contracts assume a start date.
- Hold excavation until written authorization and approved plans are in hand.
San Diego County DEHQ Septic Systems explains installation and construction pathways that implement the Final 2025 LAMP for new OWTS consistent with the State Water Board OWTS Policy.
Repair Authorization vs Full Redesign
Like-for-like component repairs may qualify for repair authorization when the system remains fundamentally the same. Failures that demand a different dispersal location or technology often leave the repair track and enter redesign.
- Document the failed component with photos, pump-outs, and as-builts when available.
- Ask DEHQ whether the scope stays repair or triggers a new design under LAMP.
- Do not bury a redesigned field under a repair label—inspectors catch mismatches.
County San Diego County DEHQ Septic Systems repair and construction guidance and the Final 2025 LAMP define when upgrades must meet current standards rather than patch-only rules.
Shared Steps: Application, Fees, and Inspections
Both paths need accurate applications, fees, and inspection holds. Skipping an open-trench inspection to stay on schedule is a common self-inflicted setback.
- Submit complete forms with APN, contacts, and licensed contractor information as required.
- Schedule required inspections before covering tanks, piping, or dispersal media.
- Keep approval letters and stamped plans on site during construction.
Follow San Diego County DEHQ Septic Systems inspection expectations; EPA’s EPA Septic Systems materials likewise treat proper installation verification as essential to long-term performance.
Choosing the Path Before You Dig
A 30-minute scoping call with the right plans beats weeks of stop-work. Joseph Bartkowski recommends lining up soil data and as-builts first so DEHQ can classify the project correctly.
- Gather the existing permit, as-built, and any prior soil reports before intake.
- Describe the failure mode honestly—surfaced effluent, collapsed baffles, or root intrusion.
- Align contractor licensing (including C-42 where required) with the permit scope.
