Where Your Water Comes From

H2O in Water

Drinking water (both tap water and bottled water) can come from a variety of different sources, including rivers, lakes, streams, ponds, reservoirs, springs and groundwater.

Monte Vista Water District's drinking water supply is obtained from two main sources:

In addition, the District owns stock in San Antonio Water Company and receives its entitlement through a connection with the City of Upland. The sources of Upland's water supply include groundwater, local surface water (San Antonio Canyon), and imported surface water.

Monte Vista Water District also distributes non-potable recycled water through a separate distribution system for customers to use for non-drinking purposes (landscape irrigation).
