Combined Sewer Overflows (CSO)
While we work to minimize CSO’s as much as we possibly can with current funding, we understand that notification of when we discharge is important to many downstream communities and other watershed users. Sign up now to receive notification when a CSO discharge occurs. We will notify you within two hours of the start of a discharge and update every eight hours.
Want to know more about how we work to reduce CSO events? Check out our High Flow Management page for a detailed review or contact a member of the Lowell Regional Wastewater Utility.
