The City of Bonaparte’s 80-year old, cast-iron water mains provided several water quality issues for the residents including rusty-colored water and pressure loss. The City has two pressures zones, controlled by one pressure-reducing valve. After completing hydrant testing, a hydraulic model of the system was developed to identify the “biggest bang for their buck” in replacing water main. A Preliminary Engineering Report was completed. A phased water replacement program was developed and used for a 2012 Community Development Block Grant (CDBG) application. Operation and maintenance items were also identified for the City’s short-term benefit. Such items included having a water loss survey completed and installing isolation valves at the pressure-reducing valves to facilitate maintenance.
