MWMC FACILITIES PLAN Project Type Allocation These improvements, which are driven by increased community performance standards, provide capacity/enhanced capability for both the growth increment and for existing users and are therefore allocated entirely to Performance. Aeration Basin Modifications - South and North Facility Component Allocation The primary purpose of these modifications is to improve the capacity of the aeration basins and the performance of the overall secondary treatment system. A secondary benefit of these projects is to provide the WPCF with additional operational flexibility during peak flow events. These projects are allocated 90 percent to Secondary Treatment and 10 percent to Peak Flow Management. Project Type Allocation These projects expand capacity as well as improve the performance of the secondary treatment system to meet the new ammonia limit and more effectively and consistently meet the BOD and TSS limits moving forward. These projects are equally divided between Capacity and Performance. Secondary Clarifier Enhancements Facility Component Allocation This project is allocated equally between Secondary Treatment and Peak Flow Management because both the base capacity of the secondary treatment process as well as the peak flow capacity of the facility are increased as a result of these improvements. Project Type Allocation This project is split equally between Capacity and Performance because the modifications to these existing units increases the liquids treatment capacity of the facility and also improves the consistency/reliability of the effluent performance. 9th and 10th Secondary Clarifiers Facility Component Allocation Construction of these two additional units increases the base capacity of the secondary treatment system and the peak flow capacity of the overall facility and therefore the allocation is split equally between Secondary Treatment and Peak Flow Management. Project Type Allocation This project expands capacity and is allocated entirely to Capacity. Conversion to Sodium Hypochlorite Disinfection Facility Component Allocation Approximately half of the cost of this project will provide the facilities to convert disinfection from chlorine to sodium hypochlorite for the base secondary effluent flow. The remaining half of the costs of this project are for providing disinfection to the high-rate clarification effluent in the case of peak flow management Alternative 4, or to the primary effluent in the case of peak flow management Alternative 5. Therefore, 50 percent is allocated to Disinfection/Ouffall and 50 percent to Peak Flow Management. 8-10 MWMC_8.0_REVS, DOC
