Status of water quality and some related factors at connected water supply stations in Cai Lay District, Tien Giang Province

Objectives: To determine the percentage of water samples taken from connected water supply stations in Cai Lay District, Tien Giang Province that met the Vietnamese Standards (QCVN 02:2009/BYT) and to determine the factors related to the water quality.

Methods: The study used test results of 81 water supply stations collected from the Tien Giang Center for Disease Control in 2020 and compared these with the QCVN 02:2009/BYT.

Results: 86.4% of stations had water quality that met QCVN 02:2009/BYT, 90.1% and 96.3% of samples met physicochemical and microbiological criteria. State-owned enterprises had the highest sample rate (100%), followed by the cooperative model (92.3%), the private enterprise model (88.2%), and the cooperative group model (81.0%). Water supply stations with self-inspection of water quality, with correct collection of prescribed prices, with operating models of settling and filtering systems, had better water quality.

Conclusions and recommendations: Water supply facilities should perform self-inspection of water quality and need to have an annual plan for renovation and upgrading of the system, including the installation of settling and filtering systems. The water fee should be raised according to regulations to have reserve funds for investment in construction and repair of water supply systems when they are degraded. Authorities need to take measures to provide technical support, convert inappropriate models, and need to take strict measures against water suppliers that do not comply with regulations.
