We were asked to take a look at the water system serving the San Isidro community. This community’s water is in short supply. Each house receives water every 15 days and they must store approximately 450 gallons at each home on the day they receive water to last them the 15 day interval. We have been monitoring source water and main supply tank meters here over the last several months to determine if there are excessive water losses in the form of waste and/or leakage. During this visit we found there is very little leakage and people are doing a good job of conserving water. This community of 450 homes needs a large scale water system improvement in the form of a new transmission main to move additional water from their source to their main tank. They have plenty of water and pumping capacity at their source, but there is a bottleneck in the two miles of existing two-inch transmission main between the source and main tank. They need a new parallel galvanized transmission main of either three- or four-inch galvanized metal pipe to provide for their short and long-term needs.
