How does Casa de Oro's climate affect this service?
Casa de Oro is mostly sewer-served through Otay Water District, but pockets of older hillside properties along the SR-94 corridor and the Mt. Helix perimeter still run on private septic. Those septic-served homes are typically pre-sewer-expansion installations on conventional gravity systems.. East County new-system installs handle a wide range, from straightforward gravity systems on well-drained DG soils to engineered ATU systems on the marginal sites.
How long does a full new septic install take from start to finish?
Plan for 2 to 4 months from first call to closed permit. The actual digging and installing is one week. The other 7-15 weeks are county DEH timelines: perc test scheduling, plan review, permit issuance, and final inspection. The pros we send handle the paperwork so you are not the one chasing the county.
What is the difference between gravity, pressure-dosed, and ATU systems?
Gravity systems are simplest, cheapest, longest-lasting, they need good soil and slope. Pressure-dosed systems use a pump to spread effluent evenly across the field, needed for marginal soils or flat sites. ATUs (Aerobic Treatment Units) treat effluent with oxygen for sites that fail standard perc, required on small lots or near sensitive water features. Cost goes up in that order.
