In 2022, 75% of Rialto's drinking water came from groundwater basins, 16% from the Baseline Feeder and 9% from surface water. [1]
Rialto has a zero-tolerance policy for detectable perchlorate; two wells have wellhead treatment that removes it to non-detect levels, and other affected wells are out of service. [2]

The median home in Rialto was built in 1982, and 43% of homes predate 1980. Homes from that era were typically built with copper or CPVC supply, plastic drains, and in some homes gray polybutylene supply pipe, which is where leaks, low pressure and drain problems usually start as they age.
