Collection System

 

The Operations Division maintains the sewer collection system that conveys sewage from Springfield to the regional treatment plant. The Division typically responds to a wide variety of customer service requests each year. We inspect and clean the collection system to prevent blockages and issues underground that could cause a pipe to break or collapse. Operations also works with the Environmental Services Division to address fats, oils and greases (FOG), which can cause major backups. Operations updates the GIS maps and database.

The Operations Division maintains 225 miles of sanitary sewer lines, varying from 6" to 60" in diameter.

Maintenance activities include:

 

  • Pipeline cleaning
  • TV inspections
  • Pipeline locating
  • Inspecting manholes
  • Pipeline repair
  • Smoke testing

 

Note:

  • Residents are responsible for their private sewer line to the public right-of-way.
  • The City is responsible for maintaining the collection system within the public right-of-way.

 

Infiltration & Inflow Monitoring (I & I)

Sewer Repair

 

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.
