wastewater_plantUpgraded wastewater treatment facilities were operated without incident and met all State and Federal requirements in 2006.  Typically 1,000,000 gallons of wastewater are treated each day at the treatment plant.  Continuous operation of the plant with no shutdowns is required each and every day.  Flow is continuous and there are no means to stop or store wastewater.  A dedicated staff certified to operate the plant is required to continuously test and adjust sixteen different treatment components to accomplish acceptable disposal of sludge and water.

Reconstruction of the wastewater treatment facilities has been recently completed.  The community has the capacity to expand with regards to accommodating additional wastewater.  Treatment improvements, combined with significant improvements of collection trunk lines in the past decade, have insured this utility is staged for the future.

The United States Environmental Protection Agency took significant steps to impose restrictions on septic tanks in the unincorporated portions of Yankton County east of the City in 2006.  Interest in a centralized wastewater collection system for the lake area west of the City remained strong.
