JVA designed and permitted the North Table Mountain Water and Sanitation District (NTM) Water Treatment Plant (WTP) Expansion. The NTM WTP is an 11 MGD conventional water treatment facility consisting of ballasted flocculation, high rate clarification, filtration and chlorine disinfection. The project included capacity expansion to 16 MGD firm capacity, providing adequate treatment redundancy during peak summer demand. JVA conducted a comprehensive performance evaluation of the water treatment, backwash and residuals handling processes to determine limiting conditions and prioritization of plant expansion and improvement components. For the backwash and residuals handling evaluation it was determined that the existing backwash recovery basins and sludge drying beds were of adequate capacity to meet near future demands with recommendations to improve and expand these facilities when flows approached 10 MGD. Water treatment improvements included new ballasted clarification pretreatment, multi-media filtration, chlorine disinfection and optimization of backwash recycle. In addition to process improvements, the project included a chemical storage facility and an administration building with state certified water quality laboratory, operations laboratory, training center, kitchen, locker rooms, and operations offices. The work also included electrical, instrumentation and controls for the new expansion and replacing antiquated systems for the existing facility.
