Most Yorba Linda properties get water and sewer from Yorba Linda Water District, while some are served by Golden State Water Company, so the water provider depends on location. The City's Building Division issues plumbing permits, and YLWD may add its own plan submittal requirements. Call the number on this page to be connected with a local plumber in Yorba Linda.

Which water and sewer agency serves our Yorba Linda building?
The City of Yorba Linda says most residents are served by Yorba Linda Water District, some by Golden State Water Company, and that the provider depends on location. YLWD serves the city plus parts of Anaheim, Brea, Placentia and unincorporated Orange County, and its mission covers both water and sewer. The City notes that water and sewer come from separate public agencies, not from the City itself. The sewer provider for Golden State Water addresses wasn't verified, so check the bills. YLWD customer service is (714) 701-3000; Golden State Water's customer service line is 1.800.999.4033.
How does the water affect commercial equipment?
YLWD's supply is about 85 percent local groundwater from the Orange County Groundwater Basin and about 15 percent imported water from the Metropolitan Water District. Golden State Water's Placentia-Yorba Linda system blends treated Orange County Basin groundwater with imported Colorado River and State Water Project water, and its latest report lists hardness averaging 11.0 grains per gallon, ranging from 3.92 to 17.5. That system adds chlorine, and the Metropolitan water it buys contains chloramine, which matters for labs, aquariums and some medical equipment. YLWD's own hardness figure wasn't verified, so check its water quality report before sizing treatment for kitchen or process equipment in the YLWD area.
What do permits involve here?
The City of Yorba Linda Building Division issues plumbing, building, electrical, mechanical and demolition permits at City Hall, 4845 Casa Loma Avenue, (714) 961-7120, with application forms submitted at the counter. The City's building FAQ notes that YLWD may have its own plan submittal requirements, so a tenant improvement in Savi Ranch or near the Town Center at Yorba Linda Boulevard and Imperial Highway can involve both the City and the district. Ask both before scheduling work.
A note on location
Yorba Linda is in northeastern Orange County, about 24 miles from Riverside, and its utilities work differently from the Inland Empire cities nearby. Have a recent water bill ready when you call so the plumber knows which provider's rules apply. Knowing whether the building is in YLWD's area or on Golden State Water's Placentia-Yorba Linda system also helps when choosing water treatment, since source and disinfection can differ.
