The Mystic River Watershed experienced significant Sanitary Sewer Overflow (SSO) events this week – the first of its kind since March 2010. The overflows resulted from the estimated 4 inches of rain received Wednesday, December 10th, overwhelming infrastructure and forcing overflows of stormwater mixed with untreated sewage into our waterways. Storm events of this kind are expected to increase in the future, demonstrating the need to update our infrastructure to accommodate large storm events. MyRWA anticipates that a high volume of SSO water was released into the environment and will report the data once received.
