Drain clogs in San Clemente range from a slow bathroom sink to a main line backup, and a local plumber can clear most from a cleanout. If the problem is in the public sewer, the City, Santa Margarita Water District or South Coast Water District handles it depending on your area. Call the number on this page to be connected with a local plumber in San Clemente.

Is the clog mine or the City's?
That depends on where the blockage is and who provides sewer at your address. The City of San Clemente runs its own wastewater collection and treatment for most of the city. Talega gets sewer and water from Santa Margarita Water District, while South Coast Water District handles a slice of the north end. Your bill shows the provider. A clog inside your house or along your own line is typically yours to clear; a blocked public main belongs to the provider. For City customers, sewer overflows can be reported on the utilities hotline at 949-366-1553.
Why do older San Clemente lines clog more often?
Census survey estimates put the median home here at 1982. Lines from that era can include cast iron that roughens inside as it ages, and joints that have shifted enough to let roots in. Rough walls catch grease and paper, so a clog that's cleared with a narrow cable may close up again within weeks. A plumber who cleans the full diameter, then shows you camera footage of the line, gives you a clearer picture of whether cleaning will hold or repair is coming.
Do winter storms make it worse?
They can. Heavy rain in this part of the coast can overwhelm drainage and stress sewer systems, and water finds its way into older lines through cracks and loose joints. If your drains back up only during storms, or a ground-level shower fills when it rains, tell the plumber; it may point to stormwater getting into the sewer lateral, and the fix differs from an ordinary clog. Keep the outdoor cleanout cap in place so surface water can't pour into the line.
One local note
If a camera shows broken or collapsed pipe, replacing it is permit work through the Community Development Building Division at 910 Calle Negocio. Simple cleaning doesn't change the pipe and is ordinary maintenance. When you call the number on this page, tell the plumber whether you're on City sewer, in Talega or in the north end, and whether storms seem to trigger the problem. That helps them bring the right equipment, from a hand auger for a bathroom sink to a jetter for a grease-lined kitchen run.
