Nuts & Bolts

The Nuts & Bolts column features OCWD construction updates each month.

Construction projects coming down the pipeline:

  • As part of the Groundwater Replenishment System Final Expansion, construction of the 3.5-mile pipeline that will bring treated wastewater from Huntington Beach to Fountain Valley began in October with excavation of pipeline installation pits. Construction will take place along the Santa Ana River trail and involves a process called slip-lining, which installs a new pipeline within an existing pipeline. This process has much less construction impacts than constructing a new pipeline and allows for staying out of the public right of way.
  • Destruction of a nested monitoring well in Huntington Beach is scheduled to start in November. Construction will take place on the west sidewalk of Brookhurst street approximately 300 feet south of the intersection of Yorktown and Brookhurst. Work will take approximately one week to complete.
  • Construction of a monitoring well cluster consisting of three separate wells spaced approximately 10 feet apart will be constructed on Oriole Avenue in Fountain Valley. The two deep wells will be drilled using the direct mud rotary drilling method and the shallow well will be drilled using the hollow stem auger drilling method. Construction is anticipated to take up to one month to complete.
  • Planning efforts continue on the Sunset Gap Seawater Intrusion Inspection as part of the District’s proactive efforts to combat seawater intrusion into the Orange County Groundwater Basin. OCWD is preparing to construct 11 new monitoring wells in Huntington Beach and Seal Beach, nine in Huntington Beach and two in Seal Beach. Construction on the two Seal Beach wells is slated to start in early 2021.­­
