Regulatory compliance ensures appropriate treatment for the community's needs. The treated effluent from Central City STP flows into nearby streams that are part of the Green River watershed, which eventually joins the Ohio River and then the Mississippi River. This drainage system supports diverse aquatic life and provides water resources for the region. The plant plays a key role in protecting local water quality and downstream ecosystems.
