Visit the GIS Infrastructure Map to see where city infrastructure projects are happening.
The City of Stillwater and Stillwater Utilities Authority is replacing and upsizing a sewer line in order to alleviate sewer overflows that occur during heavy rainfall events. The 2,600 linear feet of sewer line will be upsized to 24 inch diameter, with new manholes and service line reconnections.
This project serves to increase capacity of the sewer system to handle the increased flows experienced from new development in the City's east basin sewer drainage basin.
April 1, 2016: Design for this project is in progress. The engineer is currently evaluating options for the project to determine which replacement approach will provide the best benefit to the city.
February 3, 2017: The design phase continues. A topographical survey has been conducted. City staff are negotiating rights of entries with property owners in order to conduct the geotechnical investigation.
May 4, 2018: After an extensive re-evaluation to ensure selection of the optimal project alignment, the City is continuing to pursue rights-of-entry in order to perform geotechnical analysis.
