EPA has found that the Puerto Rico Aqueduct and Sewer Authority (PRASA) has discharged/bypassed wastewater through a point source into waters of the United States. The point source, which is an appurtenance of the Dorado Wastewater Treatment Plant, is identified as the Dorado del Mar Sewage Collection System. The wastewater bypasses have resulted due to the lack of appropriate operation and maintenance of the sewage collection system, which includes a pump station. As a measure of improving the operation of the sewage collection system, PRASA must made repairs to the pump station and must conduct a comprehensive sewer evaluation, which include an evaluation of the system capacity to handle the incoming sewage flow.
