The solution that we have already embarked upon involves upgrading the current pond and spray field system that comprises the Sheridan Wastewater Treatment Plant (WWTP). The estimated cost of completing this project is $2.3 million. Funding for this project has been obtained through a combination of grants, Cemex Development Agreement funds, and contributions from the County General Fund. Operating costs for the current WWTP are relatively low compared to the mechanical treatment systems in Wheatland or Lincoln.
Abandoning the Sheridan WWTP and pumping wastewater to a proposed new treatment plant serving Wheatland would cost $7 million, based on preliminary estimates. This option is under consideration as a potential long-term solution but is not currently feasible or cost effective.
Abandoning the Sheridan WWTP and pumping wastewater to Lincoln has also been discussed and considered. This project would likely be more expensive than the Wheatland option because the distance to the Lincoln plant is much further (3.6 miles to Wheatland, 10 miles to Lincoln).
