An experimental study was carried out with the objective of determining whether the Wastewater Treatment Plant (WWTP) is functioning adequately or whether its effectiveness in removing pollutants has decreased throughout its useful life. The evaluation of the WWTP began with the collection of information on the dimensions of the hydraulic units and the plant's inlet and outlet flow rates. Water samples were taken at the inlet and outlet of the WWTP and analyzed in an authorized laboratory. The results obtained were compared with the TULSMA 2015 regulations, revealing that the BOD5 and COD levels exceeded the limits allowed for wastewater discharge into freshwater bodies. Subsequently, each hydraulic unit was diagnosed and it was determined that they comply with the parameters established in the design guidelines and manuals for wastewater treatment plants. Finally, it is suggested to implement an operation and maintenance plan to guarantee the correct operation of the WWTP, which includes the implementation of a cover for the sludge drying bed and measures for each hydraulic unit.
