Rural roots, new subdivisions
Winchester is a census-designated place in unincorporated Riverside County, about 8 miles southwest of Hemet along State Route 79 and roughly 24 miles from Riverside in a straight line. The 2020 Census counted 3,068 residents. For most of its history it was rural farm country, known locally for spots like the Winchester Cheese Company. Then the 2000s housing boom brought new subdivisions, with schools and parks following in the late 2010s, so today older rural parcels sit beside new tract homes.
Water from EMWD
Eastern Municipal Water District (EMWD) lists Winchester among the unincorporated communities it serves, though not every rural parcel has been confirmed as an EMWD customer. Winchester is typically supplied from EMWD's Hemet Water Filtration Plant, which treats imported Colorado River and State Water Project water, and occasionally from Metropolitan's Skinner Filtration Plant. Final disinfection at the Hemet plant uses chloramine, which matters for some rubber parts in fixtures and for aquarium owners. EMWD's report puts hardness from that plant at 3.4 to 7.2 grains per gallon, averaging 5.1, which it calls moderately hard.
EMWD says its responsibility for water quality runs to the meter and refers line breaks on the customer's side of the meter to homeowners insurance, so the pipe from the meter to the house is the owner's to repair. For outages and trouble calls, EMWD's line is 800.698.0400; customer service is 800.426.3693. EMWD also runs a cross-connection control program that surveys sites and inspects and tests new backflow devices.
Sewer service in Winchester was not confirmed for specific addresses, so check your bills or property records to know whether your home is connected to public sewer before calling about a drain problem.
County permits
Because Winchester is not a city, permits go through the County of Riverside Department of Building and Safety. The county says a permit is required to replace water lines, sewer lines or a water heater. The permit counter is (951) 955-1800, and permits can be handled through PLUS Online or in person.
Gas and propane
SoCalGas lists Winchester among the communities it serves, but some rural parcels may not have gas mains. If you smell natural gas, leave the house first and then call 911 and SoCalGas at 1-800-427-2200 from outside. If your home runs on propane, leave and call 911 and your propane supplier.
How Winchester differs from Riverside
Riverside homes are mostly on Riverside Public Utilities water and city sewer, with city permits. Winchester has EMWD water, county permits and a mix of rural and new-build properties. When you call the number on this page, describe the problem and whether your home is on public sewer or gas. You will be connected with an independent plumber who covers Winchester, and price and timing are agreed directly with that plumber.
