Everyday habits that protect your system

Your septic system handles everything that goes down the drains in your Atherton home. Using less water, spacing out loads of laundry and skipping the garbage disposal all reduce the load. Keep the area over the drain field planted in grass, and know where your tank lid is so pumping visits are quick. Records of past service make future repairs and home sales easier.

Is it the drain or the septic system?

A single slow drain in a Atherton home is almost always a local clog. Several slow fixtures at once, especially with gurgling or odors, point to the septic tank or drain field. Standing water, lush grass in one strip of yard, or a sewage smell outdoors confirms it. Those are the moments to call a septic company rather than a plumber.

Finding the right local company

Local experience matters with septic work, because soil, rules and common system types change from county to county. A company that works around Atherton and Menlo Park, East Palo Alto, Woodside will know what the San Mateo County health department requires and what tends to go wrong on local properties. Ask for references on bigger jobs and keep every invoice with your home records.

Septic permits and rules around Atherton

Septic permits near Atherton are handled at the county or state level rather than by the city. Repairs, replacements and new installations usually need a permit and an inspection. Your septic company can pull the permit for you. If you are buying or selling a home, ask whether a septic inspection is required at closing.
