Southern Regional Water Supply Facility


Orange County Utilities (OCU) provides high quality potable water at its new 30 mgd, Southern Regional Water Supply Facility (SRWSF). The $21 million facility services tourist, commercial, and residential water customers and is supplied by a well field that uses six production wells to pump water from the lower Floridan Aquifer. The wells extend to depths that vary from 1,100 to 1,400 feet. This project is a first for OCU in choosing ozone oxidation as the main treatment process for this plant. Ozone is a capital cost-intensive process but is extremely effective in oxidizing sulfide in Florida groundwater.

During design, PMA was in charge of generating cost estimates at 30%, 60%, and 100% design levels. During construction and through the completion of the plant, PMA provided on-site project controls services, including tracking the construction budget, change order pricing and negotiations, and providing progress schedule reviews.
