Removing rainwater from the sewer system is important to reduce overflows at the regional treatment plant. Much of the excess water comes from downspouts,sump pumps and area drains improperly connected to the sanitary sewer. Flow monitoring and flow modeling provide measurements and data used to determine estimates of I & I. Flow meters are placed in varying locations throughout the sewer collection system to take measurements and identify general I & I source areas. The City of Springfield completed a Wastewater Master Plan in 2008 which involved inspection of the sewer system using several methods to identify future rehabilitation projects.
Repairing I & I Sources
Repair techniques include pipe patching and relining, manhole repair and replacement, disconnecting illegal plumbing, drains and roof downspouts. The City of Springfield has engaged in an active rehabilitation effort to reduce the entry of I & I into the collections system, including removing and replacing pipe that was more than 60 years old.
