Investigation of rural water supply systems and future prospect in smart perspectives:A case study of mountainous area in South China
The backwardness of rural water supply system is one of the bottlenecks that restrict the high quality development of social economy.In this paper,a mountainous town in Pearl River Delta,inclu-ding 246 economic communities assigned to 22 administrative villages was taken as representative.By means of on-site inspection,residents interviews,facilities inspection,and water release,the type of water sources,water treatment facilities,pipe networks,as well as water supply system management were thoroughly investigated within the communities.Results showed that the main water sources were listed in a descending order:mountain spring water(34.2％,counts by economic communities,similarly herein-after),river water(32.5％),mixed water(31.3％),underground water(2.0％).Water treatment technologies adopted were listed in a descending order:full traditional water purification technology(FT-WPT)(32.5％),reservoirs(30.1％),FTWPT and distributed wells(27.2％),reservoir equipped with filter(5.7％),FTWPT and reservoirs(4.1％),wells(0.4％).PVC shallow buried was mostly used compared to standards.But it was susceptible to collision,pressure and sunlight,which brings potential risks to water quality.The satisfaction rates on water quality were 71.1％(daily)and 55.7％(rain-storm),respectively.Complaints on water flow or pressure reached as high as 55.3％.There was a gap between water metering and payment,which reflected from that 73.2％of the communities equipped wa-ter meter for each household,compared to that only 32.5％payed for the water.This paper summarized the problems existing in the water supply system,solutions were also prospected in smart perspectives.
