Voice Your Opinion

Should you be interested in expressing your views or participating in decisions that may affect the quality of water, the City Council meets regularly on the first and third Wednesday of each month at 7 p.m. at 320 West Newmark Avenue, Monterey Park.

Where the Water Comes From

Monterey Park’s water supply comes from production wells located outside the city limits. These wells are in the Main San Gabriel Groundwater Basin. In addition, the city purchased water from San Gabriel Valley Water Company (SGVWC), which also pumps groundwater from the Main San Gabriel Basin. The water is tested and disinfected with chlorine before it is delivered to your home.
