Town of Sunol Pipeline Replacement Project
Overview
The Town of Sunol Pipeline Replacement project at Arroyo de la Laguna Creek is critical to continued operations and reliability of the water supply for the nearby town's residents. The current pipeline was laid in place nearly 100 years ago underneath the creek, but decades of scouring action by winter rains has lowered the creekbed and led the pipeline to be exposed above the surface. This places it at risk for damage. Replacing the aging pipeline and installing it deep under the creek bed is key to this project.

Project Background
The Town of Sunol Pipeline Replacement Project scope includes replacing approximately 550 feet of 12” diameter pipeline crossing Arroyo de Laguna Creek with 12” diameter Ductile Iron Pipe. To achieve this will require an open cut trench across the creek as well as new tie in points with gate valves. The project will include creek restoration and tree removal in the pipeline alignment as well as removal of existing pipeline within the creek from bank to bank.
The new pipeline segment will extend northwest across the creek and underneath the adjacent athletic field of the Sunol Glen School, a historic 100-year old building. After trenching and placement of the pipeline, scheduled to occur when school is not in session, the affected strip of the athletic field will be restored to its current condition.
