Encino Water Hardness & Quality Report (2026)

Encino, California, a neighborhood in the San Fernando Valley of Los Angeles — an affluent San Fernando Valley community known for the Ventura Boulevard commercial corridor, the Encino Velodrome, the Sepulveda Basin Recreation Area, a significant Jewish-American community, and a community known for its celebrity residents and upscale residential neighborhoods west of the 405 Freeway — receives its municipal water supply from the LADWP blended supply including Owens Valley Aqueduct, MWD Colorado River import, and San Fernando Basin groundwater via the LADWP Encino–Sherman Oaks distribution zone. Water hardness in Encino measures 88.5 mg/L — classified as moderately soft.

Encino's moderate softness — notably softer than Winnetka (185 mg/L) in the same San Fernando Valley LADWP system — reflects the Encino–Sherman Oaks distribution zone's higher Owens Valley Aqueduct fraction. The LADWP's central and west San Fernando Valley zones (Encino, Sherman Oaks, Van Nuys) receive a higher proportion of the very soft Owens Valley Aqueduct water (approximately 50–80 mg/L) relative to the west Valley zones (Winnetka, Canoga Park) that have more MWD Colorado River import. The Encino zone's favorable Owens Valley blend ratio produces the moderate 88.5 mg/L at Encino taps.

With hardness at 88.5 mg/L, Encino residents enjoy moderately soft water. LADWP consistently delivers water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
