Page 4 Introduction The Mashpee Sewer Commission has been considering a variety of alternatives for significantly reducing the nitrogen contribution to their estuaries from residential and non-residential wastewater. Those alternatives range from traditional gravity sewers and public wastewater treatment plants, to removal of treatment plant effluent from critical recharge areas, to low pressure collection systems (grinder and STEP)feeding neighborhood treatment plants, to denitrifying septic systems shared by clusters of homes to individual denitrifying or composting systems. Initial evaluations have concluded that relying solely on current Title 5 septic systems and older existing cesspools will cause serious negative consequences for the ecological health of estuaries and the cost of a single town-wide traditional sewer system and single public treatment plant,which was reviewed as an option by the firm of Weston &Sampson in their 1988 draft wastewater facility plan for the Board of Health would be extremely cost prohibitive due to low population densities and long runs of sewer lines. The Mashpee Sewer Commission has instead elected to focus on: ■Continuing to take advantage of opportunities to share, merge or piggyback on existing and proposed private wastewater collection and treatment systems. ■Relocating treated wastewater from those systems outside of critical recharge areas. ■Developing small scale neighborhood and cluster systems ■Finding ways to encourage use of on-site systems that reduce nitrogen impacts ■Develop approaches to Commission management and maintenance of each of the above facility types. The scope of this proposal offers information related to an Orenco Effluent Sewer System with a focus on addressing the key elements of Mashpee's Sewer Commission wastewater management plan.A key consideration of this proposal addresses the Town of Mashpee's intent to address critical areas in small increments, involving smaller amounts of up-front capital costs. Goal To provide an affordable wastewater collection system that protects the public health and the quality of Mashpee's water resources and environment through the development and maintenance of appropriate and cost effective technologies for wastewater collection, treatment, and re-use.
