The Springfield Water and Sewer Commission (SWSC) was under an Environmental Protection Agency (EPA) Administrative Order to reduce Combined Sewer Overflow (CSO) frequency and volume of discharges to the Connecticut and Chicopee Rivers. The SWSC sought innovative separation strategies and enhanced pump station performance strategies that would enable it to meet the desired level of CSO control detailed in its Long-Term Control Plan, but avoid constructing large, expensive, offline CSO storage systems or to complete area-wide sewer separation proposed by a previous consultant.
The SWSC is proceeding on a vastly different approach than that proposed in previous planning documents. The new approach assures continued regulatory compliance and, more importantly, addresses infrastructure deficiencies in a cost-effective and sustainable manner. The new plan will reduce the City of Springfield's costs to achieve its program goals by 50%, saving tens of millions of dollars.
