MASTER PLAN

The Wastewater Treatment Plant Master Plan (WWTP) is a comprehensive 30-year roadmap for SASM’s efforts to rehabilitate and replace existing infrastructure, plan for expected new legal requirements, protect it from flooding due to 100-year flood events and sea level rise, prepare for its future growth needs, incorporate sustainability initiatives and reduce the impact of the plant’s odor on its neighbors. 

WWTP Rehabilitation Project - Phase I

The first phase of the WWTP Master Plan implementation is expected to begin in April 2018 and conclude in 2020. The primary goal in this initial phase will help to ensure reliable treatment of wastewater, as well as compliance with regional, State and Federal regulations.  A key improvement will be numerous upgrades and rehabilitation of existing infrastructure to ensure compliance with the National Pollutant Discharge Elimination System permits which enhances water quality. Another component to note in this phase of the contract will be the installation of two new odor control towers, located at the northwest corner of the plant.
