Title
Upper Narrows Pipeline Replacement Project
Description
A significant storm event occurred in the Victor Valley sub region and San Bernardino County, beginning the week of December 19, 2010. As a result of the devastating rains, VVWRA sustained damage to the sewer interceptor under the Mojave River in a section of the river with extremely limited access known as the Upper Narrows. The pipe breach was discovered on December 29, 2010. VVWRA immediately began work to create an emergency sewer force main to bypass the breach in the damaged sewer interceptor and divert the wastewater through newly built temporary lines and booster pumping stations. Additionally, the force of the river flow resulting from the storm event was so great that the exposed manholes along the damaged sewer interceptor within the Mojave River (estimated to be between MH 5-1 to MH 5-8, and MH 1 to MH 4) became titled; causing further damage to the pipeline and manholes. Sand, sediment, and debris entered the pipeline at the ruptured areas.
