This was a very innovative and successful project, with the purpose of converting the City’s water supply from a gravity system with elevated tanks to a closed pumping system, without disrupting water service, and increasing the CT while reducing the amount of chlorine in the distribution system. R&E's scope of work included planning, design, permitting, funding administration, contract administration, and construction management. The project consisted of: Upgrading the raw water pumps at the Nooksack River and installing an emergency power supply. Constructing a 6-million gallon welded steel storage tank including a cathodic protection system and a dedicated fill line from the nearby treatment plant. Complete rehabilitation of an existing 3-million gallon welded steel water tank including a cathodic protection system and 1-mile of 16” dedicated fill line from the treatment plant. Installation of D.I. 16”, 18” and 24” piping and fittings at the water treatment and Booster pump station. Installing four new pumps at the water treatment plant to fill the two reservoirs from the clearwell. Constructing a 7,000 gpm booster pump station with variable frequency drives and auxiliary chlorination system at the 6-million gallon tank. Constructing a 4,000 gpm booster pump station with variable frequency drives, auxiliary chlorination system and emergency power supply at the 3-million gallon tank. Modifications to the existing water treatment plant, including new filter controls chemical feed system and emergency power supply. Modifying water treatment plant piping to work with the new pumping system and convert from the old gravity tank system to the new system. Modifying the distribution system to provide change over the water transmission lines from the old gravity tanks to the new pumping plants. This included several thousand feet of 12” – 24” ductile iron pipe. Installing a complete SCADA system linking all components with fiber optic and backup radio controls. Decommissioning and removal of two old elevated water tanks located at the middle school grounds. Developing the CT reporting system on an excel spreadsheet.
