The following report describes the proposed redesign of the East Wastewater Treatment Facility (EWWTP) for the City of Fernley, Nevada. The existing facility is designed for a flow of 3.4 MGD, but by the end of the 30-year design period in 2045, the projected maximum flow will rise to 5.45 MGD. The goal of this design is to modify and expand upon the existing treatment plant to allow the City of Fernley to treat the 30-year flow and produce an effluent of sufficient quality to use as irrigation water. Based on the evaluation of existing facilities and typical design parameters for small wastewater treatment facilities, a conventional design including grit removal, biological treatment, nitrification, secondary clarification, filtration, and disinfection is proposed. Design information for the addition of optional primary clarifiers is also included.
