Abstract

A water safety plan (WSP) has been developed for rural water supply in Dehradun district, Uttarakhand, India. Four public water utilities were chosen to demonstrate the application of WSP in improving the rural drinking water quality along with improved sanitation. Hazard identification and risk assessment carried out identified 10 hazardous events at all four utilities. Intermittent water supply, poor repair and maintenance of the supply channel machinery, and individual household sanitation practices were the potential sources of contamination. The study showed encouraging results, where the evaluated risks decreased substantially after implementing the control measures, along with improved water quality after WSP implementation which showed statistically significant results (p <.05) for all tested parameters, namely, turbidity (p =.000), total dissolved solids (p =.004), residual-free chlorine (p =.004), total coliforms (p =.000), and fecal coliforms (p =.003). The sanitation condition of water source and households also improved by adopting the suggested measures. The study recommends water safety planning, to empower the rural communities to safeguard their water sources, and for sustainable water supply management. [ABSTRACT FROM AUTHOR]
