Project Background
The town of Saugus, Massachusetts owns and operates a town-wide wastewater collection system consisting of approximately 95 miles of sewer pipe and nine wastewater pumping stations. All wastewater flows to the town’s main pumping station, the Lincoln Avenue Pumping Station, and is transported via a 30-inch-diameter force main to the Lynn Regional Wastewater Treatment Facility, owned by the Lynn Water and Sewer Commission (LWSC). On April 12, 2005, the Saugus Board of Selectmen signed an administrative consent order (ACO) issued by the Massachusetts Department of Environmental Protection (MassDEP) that requires Saugus to address certain deficiencies in its sanitary sewer system. Two subsystems in the town (Pilot Area 4A, Subsystem 5B, Subsystem PS-5, Subsystem 6A) underwent comprehensive rehabilitation programs of $1.9 million,$600,000, $1.7 million, and $632,000, respectively. Currently, a fifth subsystem (Subsystem 4C) is under construction and will be completed in December of 2011.

The Problem 
Over the past 10 years, the town of Saugus, Massachusetts, has experienced several large rain events that have caused significant sanitary sewer overflows (SSOs) and put the town’s sewer system deficiencies at the forefront of discussions with federal and state regulators. Extraneous water entering the sanitary collection system has exceeded the design capacity of the sewer system, forcing the town to pump excess wastewater directly into the Saugus River to protect the town’s main pumping station and its residents. As an additional concern, SSOs are a public health and environmental risk. The ACO issued to the town by the MassDEP required an immediate evaluation of the sewer system to determine baseline conditions, evaluate alternatives and produce a recommended program to control the SSOs.

The Objective
The objective of the SSO Facilities Plan Study was to develop and evaluate SSO abatement alternatives for the town’s SSO discharges, and present the recommended plan and implementation schedule for long-term SSO control to satisfy the regulatory agencies. A second objective, not necessarily required by the regulatory agencies, was to provide Saugus with a new, improved and reliable sewer system to replace or rehabilitate the existing system that_in some parts of town_is nearing 100 years old.
