Perception of the citizens in the city of São Mateus, Brazil, on water supply and the implications in its use

Abstract

The perception of consumers concerning the water supplied by water supply systems (WSS) can be a valuable tool for the management of water resources. This study aims to assess the perception of the citizens of the city of São Mateus, southeast Brazil, concerning the water supplied by the local WSS, and investigating the availability of other alternative sources. A survey was given to a sample of local consumers, and the results suggest that most consumers do not have a good opinion regarding the water quality, highlighting flavor, color, and intermittent supply as the main issues, especially during periods of drought. These conditions are mainly associated with the increase of the total dissolved solids in the raw water. Using private water wells is highlighted as an available alternative source for multiple domestic uses; nevertheless, this alternative may cause some concern if the exploitation of the resource is made without control. HIGHLIGHTS Reduced supply and poor water quality lead to seeking alternative sources.; Dissatisfaction with WSS services are refelcted in the choice for alternative sources.; For 71% of consumers, the water from alternative sources is good quality.; Well water is a feasible alternative source for the residents of the city.; The use of well water highlights the need for monitoring the potability standards.;
