The City of Toppenish’s Well No. 5 needed substantial repairs and renovation to address a variety of well facility deficiencies and improve system reliability, efficiency, and safe production of drinking water to serve current and future water system demands. The existing well building was completely reconstructed to provide separate rooms for the well and piping, chlorine equipment, fluoridation equipment, generator, and electrical gear. The project included installation of a new line-shaft turbine pump, motor, and variable frequency drive, electrical and control system improvements, natural gas-powered generator and automatic transfer switch, chlorine gas disinfection and fluoride treatment equipment, site improvements, chlorine contact piping, and water main extension to reconnect the well to the City’s existing distribution system.
HLA provided funding administration assistance, topographic survey, engineering design and preparation of plans, specifications, and cost estimate, construction administration and inspection services, construction staking, startup assistance, and final project closeout. Electrical and control system engineering design was provided by HLA’s electrical subconsultant, Connetix Engineering, Inc.
