Cotati may be Sonoma County's smallest city, but its septic story is bigger than its city limits: while the hexagonal downtown core is sewered, the surrounding rural ring — the lanes east toward Penngrove, parcels off Old Redwood Highway, and the West Sierra Avenue corridor — runs on private systems, many serving properties that have been in the same families for generations.
Because Cotati sits right between our Santa Rosa base and our Petaluma route, it gets the best of both schedules: we pass through practically daily, which means fast appointments and easy add-ons — if your neighbor books a pumping, same-day service for your tank on the same street costs nothing extra in waiting.
Typical Cotati jobs: routine pumping on older 1,000–1,200 gallon tanks, riser installations to end the digging ritual, and pre-sale inspections as long-held family properties change hands. Whatever the visit, you get a firm price first and a written report after.
