What it means
Grease interceptors slow wastewater so floating grease and food solids collect for removal. In septic applications they protect the tank and drain field from clogging and anaerobic upset caused by heavy kitchen waste.
Commercial kitchens and some residential setups require interceptors sized for peak flow. Regular pumping of grease waste is required to keep the interceptor and downstream septic components working.
Why it matters in Santa Cruz County
Santa Cruz County restaurants, vacation rentals, and home-based food businesses near the coast often need grease interceptors tied into septic or sewer service to meet Environmental Health standards.
Homeowner tip
Scrape dishes before washing and never pour cooking oil down the drain, even if you have an interceptor.
