The Lake Rhodhiss Wastewater Treatment Plant treated and discharged a total of 923.5
million gallons of wastewater during the fiscal year. That was an increase in flow over the
previous years and resulted in an average daily flow of 2.53 million gallons per day. Over 5000
samples were collected and analyzed during the fiscal year and all quarterly Whole Effluent
Toxicity Tests were passed during the previous fiscal year. During the fiscal year, the Town of
Valdese received a total of two violations, of which were a direct result of rain events and
equipment malfunction. The Town plans to pursue additional funding to address the issue of
Inflow and Infiltration associated with significant rain events that cause dilemmas at the Lake
Rhodhiss WWTP. There was no adverse effect to the environment as a result of these violations.
