Flow and loading reduction alternatives: Infiltration and Inflow (I/I) reduction 2 Reduction of household water consumption. Pricing policy for water and wastewater service. Wastewater reuse and recycling. Reduction of wastewater loadings. Waterless toilets. Growth management regulation. 4. Additional non-wastewater nitrogen mitigation alternatives: Reduction of nitrogen from fertilizers and pet wastes. Watershed modifications and constructed wetlands for nitrogen attenuation. Stormwater management and treatment. Pond inlet modifications to provide improved tidal flushing. Modified zoning or sewer use regulation. Nitrate barrier wall considerations. 2 This is for the existing wastewater collection system outside of the Planning Area pertaining mainly to the older Woods Hole collection system. Town of Falmouth, MA ES-8 Draft Comprehensive Wastewater Management Plan and Draft Environmental Impact Report 7104510.6
These alternatives were evaluated for feasibility, effectiveness, and other criteria, and from all of these potential solutions, the following ones were identified to be evaluated in detail: 1. Sewer extension to the Planning Area to collect the current and future septic system nitrogen loadings that are causing the problems. 2. Advanced treatment (Enhanced Nitrogen Removal or ENR) with Sequencing Batch Reactor (SBR) technology followed by polishing filters (Treatment Scenario “A”) at one of the following alternative treatment sites: Existing Blacksmith Shop Road WWTF site (Alternative 1A) Falmouth Country Club site (Alternative 2A) MMR/Otis WWTF site (Alternative 3A) 3. Possible additional treatment to further reduce nitrogen and treat for the emerging contaminants of endocrine disruptors, pharmaceuticals, and personal care products. 4. Treated water recharge at the Falmouth Country Club site. 5. Improved lawn fertilizer management practices. 6. Improved stormwater management. 7. Pond inlet widening at selected ponds to increase tidal flushing, thereby potentially reducing the amount of upper watershed nitrogen removal required. 8. Possible watershed modifications (freshwater wetland and pond improvements and/or restorations) to increase the amount of nitrogen that is naturally attenuated in the watershed. The main findings of the Needs Assessment Report and the Alternatives Screening Analysis Report, as well as the alternatives selected for detailed evaluation, were summarized in the December 2007 Environmental Notification Form (ENF) document and submitted to initiate the Town of Falmouth, MA ES-9 Draft Comprehensive Wastewater Management Plan and Draft Environmental Impact Report 7104510.6
