McFadden Engineering, Inc. was retained to assist Mobile County Water, Sewer and Fire Protection Authority (MCWSFPA) with the expansion of the overall water distribution system in south Mobile County. As an initial task, McFadden Engineering developed an original water model for the entire system, which was comprised of more than 125 miles of distribution lines, five water wells and three existing elevated tanks. The proposed system expansion was included in the model, which included modeling two elevated storage tanks and a new water supply well to evaluate the new infrastructure’s impact on the existing system.
Based on the results from the hydraulic model, the design of two new 1-million gallon elevated tanks, a new 850-gallon per minute water well and control building, and two new pressure reducing stations began. McFadden Engineering also acted in support of MCWSFPA by assisting investment bankers and attorneys in the issuance of a $5 million dollar bond issue used for construction.
McFadden Engineering provided additional assistance to MCWSFPA in the acquisition of the Southeast Mobile County Water System at Alabama Port. After the acquisition, McFadden Engineering designed 17 miles of water line extensions and new service, including a 1,500 linear feet directional bore under Fowl River.
During McFadden’s tenure working with MCWSFPA, numerous line extensions and upgrades to the existing system were performed including the rehabilitation and painting of elevated storage tanks, the design of 44 miles of ductile iron pipe for the major expansion of the Authority’s water service area, and the general upgrade of existing system.
