Preliminary exploration on application of "Social supervision" to secondary water supply

ObjectiveTo explore the "social supervision" mode for secondary water supply management with social power participation, to promote industry self-discipline, and guarantee the sanitary safety of drinking water.

MethodsA supervision mode for cleaning and disinfectionprocess of the secondary water supply facilities was carried out by the village committee/urban neighborhood committee and the owner′s representatives, then the differences were compared between before and after the implementation of "social supervision" by performing the residents′ questionnaire survey satisfaction and the health management survey.

ResultsAfter carrying out the "social supervision", the satisfaction of residents with the property health management rose (χ²=8.54, P < 0.01); and so did the satisfaction of residents for the cleaning and disinfection effect of the water tank (χ²=3.92, P < 0.05); the indicators of information disclosure from the property management had been improved; there was no statistical significance in comparing water quality; the participating owners mainly aged over 50 were 58.77%;the duration was different between different properties in cleaning and disinfection process.

ConclusionCarrying out "social supervision" mode partially improves the health management of the secondary water supply and updates the information disclosure of the cleaning and disinfection process, promoting the standardization of cleaning and disinfection done by the third party agencies; however, there is still the need for enhancement of standardized operating process and security safeguards in this regard.
