What Makes Culver City's Water Unique?
Local geology and source profile
Culver City, California, in Los Angeles County — the 'Heart of Screenland' (Culver City's historic nickname from the golden age of Hollywood — home of Sony Pictures Studios, formerly MGM Studios; Amazon Studios; and Apple Studios), an independent city enclave within the west LA metro, home of the Museum of Jurassic Technology, the Helms Bakery arts district, a walkable urban-infill city rapidly growing in the tech and entertainment industries, and a diverse west LA community adjacent to Santa Monica, Venice, and West LA — draws its municipal water supply from the West Coast Basin and MWD import via the City of Culver City Water Division. Water hardness in Culver City measures 64.5 mg/L — classified as moderately soft.
Culver City's moderately soft supply reflects the West Basin Municipal Water District's effective advanced treatment. The West Basin Municipal Water District (WBMWD) serves Culver City and applies advanced treatment including partial reverse osmosis to the blended MWD Colorado River (very hard: ~280–310 mg/L) and State Water Project (soft: ~80–100 mg/L) supply, plus local West Coast Basin groundwater. The WBMWD's advanced treatment in the Culver City zone produces the moderately soft 64.5 mg/L.
With hardness at 64.5 mg/L, Culver City residents enjoy moderately soft water. Culver City Water Division consistently delivers water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the West Coast Basin (LA Basin coastal plain aquifer) and Metropolitan Water District (MWD) import via the City of Culver City Water Division — the Los Angeles County west side West Basin (West Basin Municipal Water District zone — MWD Colorado River and State Water Project blend, effective West Basin treatment); moderately soft supply at 64.5 mg/L — reflecting the West Basin Municipal Water District's effective advanced treatment in the Culver City zone.
