The city of Folsom began work on the 24-inch water pipe running down East Bidwell Street to Folsom Ranch. Folsom currently provides water to more than 25,000 connections. The major city project lays a new 24-inch pipeline to provide reliable and redundant water service to Folsom Ranch. Part of the plan is to take advantage of unused Folsom water rights to the American River and the lake, staff said. … Much of Folsom water by right does not get used in typical years, authorities said. A portion of the water saved, which would otherwise flow down the American River for others to use, will serve Folsom Ranch instead, staff explained.
