- Abstract:
- To solve equipment aging and operational management risks in secondary water supply facilities, the problems of 128 secondary water supply points were investigated by questionnaire. In addition, the water quality risk and influencing factors were analyzed. The results showed that the secondary water supply facilities have weak airtightness issues such as water tank not being locked and ventilation holes lacking anti-mosquito devices, part of facilities have equipment and pipe aging, and part of facilities did not clean, or install online monitoring, and video security systems in accordance with regulatory requirements. Moreover, the water quality indicators ( pH, free chlorine, total bacteria, aluminum, and iron) are at risk of exceeding the standard. It was suggested that the primary measures to improve the water quality of secondary water supply facilities are to optimize the management mode through the correlation analysis of water quality and influencing factors, and the construction of cement facilities before 2005 should be prioritized.
