When completed, the Aspen Creek Relief Line will replace two wastewater lift stations (Grey Oaks and Florence Lift Stations) with a gravity sewer. The project was funded by Oklahoma Water Resources Board loans, supplemented by Vision 2025 Surplus funds. It was designed by Holloway, Updike, and Bellen, Inc. Right-of-way acquisition was completed in May 2016, and an environmental survey was recently completed. The project was advertised for bids on June 29 and July 6, 2016. Bids were opened on July 21, 2016 with the lowest responsible bidder being Triangle Construction, and Utility, L.L.C., in the amount of $799,938,00.
