The City has been actively working to improve Cole Creek Interceptors downstream of the Cole Creek CSO basin. The interceptors are located on opposite sides of Cole Creek and are connected at multiple locations via siphons under the Creek. The interceptors have been deteriorating due to root intrusion and other defects. Based on modeling recommendations, continued rehabilitation efforts are needed to improve operations and reliability.
The East Cole Creek Interceptor Rehabilitation Project is located along the east bank of Cole Creek. The interceptor’s capacity – its ability to convey the flow of water – has decreased over time due to sediment buildup and root intrusion. This project will rehabilitate the interceptor from Miami Street to Cass Street.
An interceptor is a major sewer line that receives flows from other sewer lines and stormwater drainage systems. This combined flow is then directed to a wastewater treatment facility or another interceptor.
Since interceptor sewers serve collected flows, they are among the largest pipes in a sewer network. Some interceptor sewer lines can be over eight feet in diameter and convey millions of gallons of wastewater per day.
In lieu of a public meeting at this time due to COVID-19, we have prepared a short summary video that explains this project in much greater detail. Please do not hesitate to reach out to the team listed below with any questions you may have.
Preliminary Design for the project is anticipated to begin in 2022 with construction beginning in 2024. The project is estimated to be complete by April 2025.
