Minimum separation distances between septic tanks, pipes, mounds, and drain fields and wells, buildings, property lines, and waterways required by code.

Setback Requirements

Also called: Separation distances, OWTS setbacks

What it means

Setbacks keep untreated or partially treated wastewater away from drinking water, buildings, and surface water. They apply to tanks, pipes, mounds, and repair areas measured from edges and invert elevations.

Reducing setbacks usually requires engineered justification or impossible on tight lots, which pushes designs toward smaller footprints or alternative treatment.

Why it matters in Santa Cruz County

Santa Cruz County setbacks to creeks and the ocean are especially strict, shaping where fields can go on narrow coastal parcels and canyon homes.

Homeowner tip

Before planting trees or building sheds, compare your plan to the septic diagram setbacks so you do not encroach on the field.
