All wastewater systems discharge the effluent water they produce (cleaned wastewater) into rivers or through land application. Since Thompson's Station cannot discharge into local rivers per TDEC standards, the Town is forced to land apply the effluent and have purchased land over the past 10 years for drip fields. At the Heritage System, the surrounding fenced-off fields are designated as spray drip fields, where the effluent is applied over the ground by sprinklers. At the Regional Plant, drip fields are purchased in various locations where lines are run underground and effluent is dripped into the land.
