Site work for a civil project in Santa Barbara, California. Completed plans call for site work for a water / sewer project.

**As of May 21,2021 This project has been awarded. Start date is 6/28/2021 and completion date has not yet been established.** Maintenance of the two anaerobic digester tanks occurs approximately every five to seven years, depending on their condition. Cleaning includes power washing the interior walls, roof, and piping inside the two tanks, and then followed by coating and concrete crack repairs. Prior to cleaning and performing any surface repairs, the contractor shall remove and dispose of all remaining digester contents, approximately $200,000 gallons from each tank. In addition, the work includes replacing the 8-foot diameter steel cover (digester dome) centered on the roof of each tank, replacing the digester gas equipment associated with each digester dome, and replacing various-sized digester valves. The Project also included the installation of new pressure indicator transmitters (PIT) on the digester domes, and the modification of the existing digester gas piping in order to accept a new connection in preparation for a future City gas-piping project. This Project also includes the demolition of the abandoned sludge piping in the Digester Control Building. Each tank has a 75-foot inner diameter, is 25 feet in height, and has a cone depth of 5.5 feet.
