In Pauma Valley, a hidden leak usually shows up as a higher bill from Yuima Municipal Water District or Rancho Pauma Mutual Water Company, or as a meter that keeps turning. On agricultural and rural lots, long buried lines and irrigation are frequent sources. Call the number on this page to be connected with a local plumber in Pauma Valley.
Which water company do I call if the leak is near the meter?
That depends on the address. The Pauma Valley Community Services District lists two water providers for the area: Yuima Municipal Water District and Rancho Pauma Mutual Water Company. Yuima can be reached at (760) 742-3704. Rancho Pauma Mutual's main office is (760) 615-4050, and it publishes an after-hours water emergency line at (760) 525-0364. Your bill tells you which one serves you, and that company should be the first call for water coming up at the meter or along the road. Everything past the meter is the owner's to repair.
What about the water itself?
Yuima's supply blends groundwater pumped from the San Luis Rey River's Pauma Groundwater Basin with treated imported water from the Metropolitan Water District. Yuima also runs a backflow program to protect the public supply, so a property with irrigation or other cross-connections may have an assembly that needs upkeep, and a failing one can leak into the ground. Rancho Pauma Mutual customers should check with their own company about its water and requirements.
Are homes here likely to have hidden leaks?
Many are at an age where it's common. The median home in the Pauma Valley area dates to about 1985, and around 37 percent were built before 1980. Original valves, supply lines and water heater connections wear out with time. Rural and agricultural properties add long yard lines, irrigation for groves and runs to outbuildings, all of which give water more places to escape unseen. A plumber will usually shut off branches one at a time and use the meter, line tracing and acoustic listening to narrow down the source.
Local note
Pauma Valley is unincorporated, so permits for larger repairs go through the County of San Diego Planning & Development Services.
