The sewer system for Top O’ Topanga is a small wastewater collection, treatment, and disposal system designed to treat residential wastewater then discharge it to the environment.

Please do not flush anything other than human waste and toilet paper. Our community has its own waste water treatment plan and cannot break down any other material, resulting in costly fixes.

Even items that claim to be “flushable” clog our system. Please do not flush “flushable wipes”, diapers, facial tissues, tampons, pads, paper towels,  cotton swabs, condoms, cigarettes, oil, grease, chemicals, medications, trash, or other non-biodegradable products. Please bag these items and put them in the appropriate trash containers. Other safe toilet paper alternatives include bidet toilet seats and perineal irrigation bottles, which can be purchased online.

Our wastewater treatment plant is overseen by the Ventura Regional Sanitation District (VRSD).
