- Abstract:
- Field research was conducted on buildings and communities randomly selected from 18 representative cities in China to investigate the current situation of secondary water supply facilities and the problems existing in operation and maintenance management in typical domestic cities. The questionnaire data were analyzed statistically. In the 175 secondary water supply points investigated, the water supply equipment using the combination of frequency conversion pump and low water tank accounted for 53.37% of the total number investigated, and the water tank material made of 304 stainless steel accounted for 71.34%. The following measures were proposed according to the investigation results:the secondary water supply facilities and their materials should be reasonably selected, it was necessary to strengthen supervision and urge water supplier to clean and disinfect the secondary water storage facilities regularly, the on-line water quality monitoring equipment should be installed, the emergency measures for immediate changes in water quality should be formulated, the inspection management of secondary water supply points should be strengthened and inspection mode should be reasonably selected to ensure the safety of water quality.
