District Construction
Salt air hills project -
The Midway Sewer District and the Highline Water District replaced much of their facilities in the Salt Air Hills area. Click <here> for a map of the area.
The Midway Sewer District would like to thank the Salt Air Hills community for all their understanding and support during the recent Sewer and Water replacement contract.
Thank you also to the Cities of Kent and Des Moines for their efforts and cooperation.
Midway Sewer District and Highline Water District completed a challenging and rewarding project with everyone’s help.
Here's what it looked like during the project:
Here's after we completed the project and repaved the road:
des Moines rehabilitation project
The Midway Sewer District has started preliminary engineering for the rehabilitation of the sewer mains in the downtown Des Moines area.
The District has contracted with the engineering firm Roth Hill, LLC to plan and design the project. These sewer pipes were installed in 1959 and are some of the oldest pipes in the District.
These pipelines have provided continuous sewer service to the downtown area of Des Moines for over 50 years. This project is anticipated to be done without major excavation. The process selected will be trenchless in nature and should minimize traffic impacts and inconvenience to the community.
small works project 2008a - 32nd avenue south & 192nd street -
The Midway Sewer District had several cracked tees and other defects in the sewer on 32nd Ave. S., north of S. 192nd Street.

We replaced about 800 lineal feet of 8” sewer main and about 500 feet of 6” lateral sewer (sewer stubs) to completely eliminate all of the defects.
Construction began in early 2009, and accepted as complete in April 2009.
submarine outfall project - Thank you to the community
After years of planning and study, the Midway Sewer District completed the last portion of its new outfall in December, 2007.
We would like to thank the community, the Des Moines Marina, and the Parks Department for all their patience and cooperation.
Use of the new outfall will free up the old outfall for the benefit of Des Moines Creek, preventing flooding and erosion.
Why did we do this....
The new outfall was needed to prevent treated effluent from overflowing into Des Moines Creek during major storm events and to accommodate increasing demand.
Once construction of the new outfall was complete, the District allowed the Des Moines Creek Basin Committee to use the old outfall. They plan to use that pipeline as a creek high flow bypass to remove some of the peak flow from the Des Moines Creek and thereby help prevent flooding, erosion and damage to the stream bed environment.
