2024 Forcemain Improvements


2024-2026 Forcemain Improvements


The 2024-2026 Forcemain Improvements Project includes sewer improvements for three areas within the wastewater system.  The Garlock Slough, Green Acres, Nodlands, and Orleans forcemains have deteriorated beyond their useful life and need to be replaced.  The Green Acres forcemain is being re-routed through the West Interceptor to provide system capacity for new development at the Pixlers lift station and West Okoboji.  These projects are being done to address the needs of aging infrastructure while managing future anticipated flows within the system.

Project Background

Throughout the last century, the Iowa Great Lakes Region has grown significantly and as a result, so has the demand on our wastewater network. To make sure we are able to keep up with our current service levels and accommodate future growth, it’s critical we repair and replace our wastewater infrastructure just like we do with bridges and roads.

In the Iowa Great Lakes region, most homes, businesses, schools, and other facilities are connected to one wastewater treatment plant through an extensive network of sewer pipes. The Iowa Great Lakes Sanitary District monitors and operates the sewer network for the area and has identified aging infrastructure in the Arnolds Park and Milford region that requires replacement to ensure continued and improved service for residents and businesses in this area.
