Unidirectional Flushing Program, Capital Efficiency Plan™, and Water Main Design, Melrose, MA
Tata & Howard provided assistance during the City’s unidirectional flushing program. As part of the work, Tata & Howard recorded the flow from the hydrants, noted any changes in the plan, and noted any defective hydrants or valves. When completed, a summary report outlining the total usage of water and recommended improvements to the flushing program was provided.
Water Mains and Capital Efficiency Plan™
Tata & Howard also provided design and construction services for approximately 5,600 feet of new 8-inch water main and approximately 950 feet of new 12-inch water main throughout the City. Plans were created using available GIS data from the City and field verification. These water mains also included crossing two MWRA transmission mains and crossing the Lynn Fells Parkway. The Lynn Fells Parkway crossing required permitting with the Department of Conservation and Recreation and a traffic management plan. This work was funded through the MWRA. As part of the project, Tata & Howard updated and verified the City’s existing hydraulic model, which has over 80 miles of water main. Work included two days of fire flow tests throughout the City and allocation of demands using up-to-date billing and parcel data. The locations of the new water mains were selected based on preliminary recommendations identified in the Capital Efficiency Plan™ that was prepared by Tata & Howard. The Capital Efficiency Plan™ identified and prioritized areas for improvement within the distribution system. Our services included evaluating the condition of the existing distribution system infrastructure to determine the adequacy of meeting present and future demands, assessing and prioritizing system improvements, reviewing and evaluating typical fire flows throughout the system, creating a pipe asset management rating system, and recommending improvements to the distribution system.
