Since July 1, 2023, Santa Cruz County requires a septic tank inspection report and a seller and buyer disclosure when rural property on septic is sold (County Code 7.38.216). The pumping report must be less than 12 months old at close of escrow and include a leach field flow test of at least 250 gallons. Since September 1, 2025, rural sales on a private well also need a well yield and water quality test and a disclosure filed with the county.

FAQ

Quick answers

What does an enhanced septic system in Bonny Doon need?

County Environmental Health requires owners of enhanced treatment systems to contract with an approved Onsite System Service Provider for regular inspection and maintenance. The county sets how often and what gets checked. When the home sells, the buyer must receive a service provider inspection report from the 6 months before close of escrow.

How do I protect my well and septic system together?

Keep vehicles, buildings, pools and paving off the leach field, send roof and yard drains away from it, and keep chemicals, paint and grease out of your drains. Use less water where you can, which the county notes can extend the life of the system. Pump the tank on schedule so solids do not reach the field.

How often should I pump my Bonny Doon septic tank?

The county recommends every 5 to 10 years depending on household size and water use. Only a county registered liquid waste hauler can pump a tank, so plan for truck access down long driveways and through gates. We do not pump tanks, but we can inspect the tank and filter and install risers to make pumping simpler.

What is required to sell a Bonny Doon home on septic and a well?

For the septic system, a tank inspection report and seller and buyer disclosure are due before close of escrow, with a pumping report under 12 months old that includes a leach field flow test of at least 250 gallons. Since September 1, 2025, the seller must also test the well for yield and water quality and send a disclosure to the buyer and the county.
