What it means
Alternative septic systems use engineered components to treat or disperse effluent where conventional trenches are not suitable. Examples include mound systems, pressure dosing, sand filters, and aerobic treatment units.
These designs follow stricter permitting, construction, and maintenance rules. They are chosen for tight lots, poor soils, high groundwater, or sensitive watersheds.
Why it matters in Santa Cruz County
Santa Cruz County Environmental Health reviews alternative systems throughout the county, especially in the mountains, along creeks, and on coastal bluffs where clay, rock, or shallow depth rule out standard leach lines.
Homeowner tip
Ask for the approved operation and maintenance manual when you buy a home with a non-conventional system.
