BACKGROUND: The Riverside Public Utilities Department (RPU) operates and maintains 52 active groundwater wells located throughout Riverside, Colton, and San Bernardino to supply drinking water to the City of Riverside. The existing Gage 29-3 groundwater well is located in the City of San Bernardino and was constructed in 1929 at a depth of approximately 300 feet. Over the years, the production capacity of this well has dropped as related to the declining groundwater table in the area. At times, air entrapment has caused the well to be inoperable. The existing well is too shallow to allow for lowering of the pumping equipment and therefore needs to be replaced with a new deeper well. At this time, Gage 29-3 is only used sparingly as its production capacity is limited and what water it does produce has a significant amount of entrained air that upsets the treatment process at the nearby plant.
