Document Description
Golden Mussel ICT plans to trench in three locations along the coastal aqueduct branch to run conduit for chemical injection lines and possibly electrical cords. All trenching will take place within aqueduct access roads. A backhoe will be used to trench and backfill. All trench work will be completed by San Joaquin Field Division staff. Each trench will be at least 6-inches wide, 14-inches deep, and less than 40-feet long. The chemical tubing will be hosed in PVC 2-inch diameter conduit. All work will take place within the DWR right-of-way. This work is necessary to prevent the spread of invasive golden mussels and to protect State Water Project infrastructure.
