he Brevard County Utilities South Central Wastewater Treatment Facility (WWTF) serves the growing area of Viera. The WWTF had a rated capacity of 6 mil gal per day (mgd) and needed additional capacity to serve further development in the area. Brevard County (county) issued a request for qualifications to select a design engineer for a 3-mgd expansion. Due to the high rate of development and population growth projections in the service area, a 6-mgd expansion was recommended. Ultimately, the WWTF was expanded from a rated capacity of 6 to 12 mgd.
Project Components The overall project consisted of the following: S A new 12-mgd pretreatment structure. S Rehabilitation of the existing 6-mgd biological process mixing equipment. S Installation of a new 6-mgd biological process train. S Clarifiers, cloth media filters, chlorine contact, aerated sludge holding, and sludge dewatering expansion. S 1-mil gal (MG) reuse storage tank. S High-service pumping reuse. S Remodel of the existing operations building and laboratory. S Construction of a new maintenance building for the service area’s maintenance staff.
