Plumbing services in Calimesa
Between Yucaipa and Beaumont
Calimesa is a small Riverside County foothill city on I-10 between Yucaipa and Beaumont, about 20 miles from Riverside in a straight line. It incorporated in 1990, and the 2020 Census counted 10,026 residents. It grew from a rural town of single-family homes and ranches, and large planned developments such as Summerwind Ranch at Oak Valley, JP Ranch and Mesa Verde are adding newer subdivisions. County Line Road, Calimesa Boulevard, Singleton Road, Sandalwood Drive and Cherry Valley Boulevard are the main streets.
Which water company serves you?
Water service in Calimesa is split. South Mesa Water Company owns water mains in the area, including along County Line Road, and Yucaipa Valley Water District (YVWD) operates facilities in the city as well, such as a reservoir on Singleton Road. Exact boundaries vary by street, so the name on your water bill tells you whom to call about a meter or main problem. Hardness numbers were not available for either system here; Inland Empire water is generally hard enough to leave scale in water heaters and fixtures, and each provider's water quality report has its figures.
Sewer is also address-specific
Newer homes at Summerwind Ranch are sewered by YVWD, which pumps flows to its Wochholz Regional Water Recycling Facility in Yucaipa. Sewer service for the rest of Calimesa varies by address. YVWD's own sewer rules apply in Calimesa, and for its customers it says the property owner is responsible for backups between the house and the sewer main. If you are unsure who provides your sewer, check your bills before a drain call so the plumber knows what to expect.
Two kinds of housing
Calimesa's older ranch properties and its new subdivisions have different plumbing needs. Older homes can have long service lines across bigger lots, aging galvanized pipe and outdoor hose bibs and lines exposed to foothill frost. Newer tract homes tend to call about water heaters, pressure and valve issues, and slab leaks. A housing-age figure for the city was not available.
Permits and gas
The City of Calimesa Community Development Building & Safety Division is at 908 Park Avenue, 909-795-9801 ext. 226. A city handout covers water heater installation, including an electrical circuit requirement for new or changed water heaters. SoCalGas provides natural gas. If you smell gas, leave the house first, then call 911 and SoCalGas at 1-800-427-2200 from outside. Homes on propane should call 911 and their propane supplier.
Calimesa compared with Riverside
Riverside's water mostly comes from Riverside Public Utilities, and its sewer from the City. Calimesa has two water providers, address-specific sewer service and a mix of rural and brand-new housing.
