Where Does Our Water Supply Come From?


Every time you turn on the faucet, you are tapping into a complex water delivery system. We have one basin that supplies water for the entire San Gabriel Valley. For 60 years, Upper District has been educating residents about our local water supply in the San Gabriel Valley and the importance of protecting this most precious resource for the sustainability of our Groundwater Basin. Upper District will take you on that journey of discovery of where our water comes from.
