New Sewer Main Construction Update

Shawnee, Oklahoma, February 14, 2023 – Construction has begun on the new sewer main included in the City of Shawnee Wastewater Treatment Plant update. The line is over 8 miles long and will be under construction for the next year. 

Downey Contracting, LLC, is the contractor for the City of Shawnee handling this lengthy project that extends from Garret’s Lake Road to S. Bryan Avenue. The route mostly follows Brangus Road, then E. Highland Street, E. Main Street, and S. Bryan Avenue, to the existing treatment plant on E. Dunbar Street. Downey will be placing information, including a contact name, on the doors of residences that may be affected. Click here to view the Wastewater Treatment Plant Expansion map.

“While it is Downey’s priority to get the job done, they will gladly work with residents to lessen the impact and keep them informed,” said Seth Barkhimer, Director of Engineering for the City of Shawnee.

The City of Shawnee Wastewater Treatment Plant project encompasses over $117 million in critical public infrastructure improvements.  The project includes the replacement of 40-year old wastewater treatment plant and the conversion of a 70-year old wastewater treatment plant into a lift station.  The project will provide protection of citizen health and safety, promotion of continued community growth, and allow for future expansion capabilities to support the next generation.  Funding for this project is made possible thanks to the Shawnee voters who approved a 0.5% sales tax in January 2023.
