Whose sewer is it?
Moulton Niguel Water District provides wastewater service to most of Aliso Viejo and keeps an overflow response plan, while the Via Iglesia area is served by El Toro Water District. If the backup comes from the main, the district should hear about it.
- Call the district if the main is blocked
- Call a plumber for the drain
- Keep photos for the insurer
Gray water from a washer or dishwasher is handled on the appliance leak water damage page.
