He added through a test of water quality at 1,400 locations (where people can not access to clean water) in 7 districts including Binh Chanh, Hoc Mon, Cu Chi, Nha Be, Binh Tan, Thu Duc and District 12, the results show that 58 water samples meet physicochemical standards (4,14%), most of them can not meet standards due to low pH level, high iron water  content; 1,299 samples meet microbiological standard (92,8%); 45 samples meet physicochemical and microbiological and standards (3,21%). Therefore, underground water quality almost can not meet Vietnam criteria 02:2009 issued by Ministry of Health.

Seeking a long-term solution in 2016-2020, Mr. Nguyen Huu Tin said HCMC will focus on key solutions: investing a network, of which a network of 1,200km will be invested in 2015 to supply clean water for 116,700 households. For the rest of 241,000 households, HCMC will supply water through hygienic water supply stations. Till end of 2015, HCMC will invest 28 other water supply stations but it is only meet demands of 13,000 households. Other solution is to install water tanks, it is expected that 1,500 water tanks will be installed but facing problem of installation locations.

Mr. Nguyen Huu Tin said, in 2016, HCMC will continue to push up its investment to achieve the target of 80-95% of households accessing to clean water in 2020. The rest will rely on water tanks or installing water processing equipment at households. In addition, HCMC will step by step call for socialization in clean water to mobilize resources, investors based on the principle that the State controls water price and quality.
