What Makes La Habra's Water Unique?
Local geology and source profile
La Habra, California, in northwest Orange County at the Los Angeles County border in the Puente Hills footslope — a residential community in the Whittier Narrows–Carbon Canyon corridor — draws its municipal water supply from the Central Basin and Coyote Hills Basin groundwater and Metropolitan Water District (MWD) imports via the City of La Habra Water Utility (serviced by the Central Basin Municipal Water District and the Municipal Water District of Orange County). Water hardness in La Habra measures 38.5 mg/L — classified as very soft, among the softest in the Los Angeles–Orange County area.
La Habra's very soft supply reflects the Coyote Hills Basin's excellent managed recharge program. The Coyote Hills Basin in the La Habra–Brea corridor at the Los Angeles–Orange County boundary is actively recharged by the Central Basin Municipal Water District with soft MWD State Water Project imports (SWP Sacramento–Feather River — 20–50 mg/L hardness). La Habra's water utility receives primarily the SWP-dominated MWD supply through the Central and West Basin distribution, with the Coyote Hills Basin ground water maintaining very soft conditions from the dominant SWP recharge. The extraordinary 38.5 mg/L at La Habra ties with Reseda (38.5 mg/L) as among the softest in the Los Angeles metro area.
With hardness at 38.5 mg/L, La Habra residents enjoy very soft water with essentially no scale challenges. City of La Habra Water Utility and Central Basin Municipal Water District consistently deliver water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
Geology & Source: Mixed supply from Central Basin (Los Angeles Coastal Plain) / Coyote Hills Basin groundwater and Metropolitan Water District (MWD) imports via the City of La Habra Water Utility and the Central Basin Municipal Water District — the Los Angeles–Orange County boundary Coyote Hills–Puente Hills zone; very soft supply at 38.5 mg/L — among the softest in the LA–Orange County boundary zone — reflecting dominant MWD SWP soft water imports and managed basin recharge.
