The Santa Clara Valley Water District treats water from multiple sources, including local wells and imported surface water from the Sierra Nevada. This blending creates variable hardness levels across San Jose's service area. Neighborhoods relying heavily on well water, particularly in South San Jose near the Almaden Reservoir and in pockets of Evergreen, experience hardness readings exceeding 12 grains per gallon. This level of mineral content accelerates scale formation inside tank water heaters, reducing their functional lifespan by 40 to 50 percent. The hard water treatment benefits become critical when you consider water heater replacement costs, which range from $1,200 to $3,500 installed depending on tank size and fuel type.
