Huckleberry Island Water Main Repair Project

On September 6, 2021, the San Lorenzo Valley Water District (SLVWD or District) suffered a major main break of a 12-inch main between the District’s Felton wells and its Boulder Creek system. This main generally referred to as the “HUD main”, is the primary backbone used to move well water north in the summer and treated surface water south in the winter. After the 2020 CZU Complex Fires the HUD main is the only potable water source into the District’s north system (Ben Lomond, Brookdale, and Boulder Creek). A single 6-inch connection to the HUD main also provides the residents of Huckleberry Island with potable water. The HUD main suffered a failure attributed to excess shear stress imposed on the main by soil movement. District staff responded and installed a temporary pipe coupling to restore service prior to storage tanks running out of water for the north system.

The District is now planning to move forward with permanent repairs to ensure a potable water supply for these communities. The preferred alignment of the new 12-inch main will make a connection to the existing main east of Huckleberry Island and north of Pacific St, run south to Pacific St (a private ROW), then west along Pacific St to the Huckleberry Island bridge. The new main will cross the San Lorenzo River on the Huckleberry Island bridge, then run north and east along the existing 6-inch main easement to the existing 12-inch main, where it will make a connection to the existing 12-inch main north and west of the recent break location.
