An Affordable System for Remotely Monitoring Water Quality in Residential Water Tanks

Water is an essential human need. In July 2010, the United Nations General Assembly explicitly recognized the human right to water and sanitation and acknowledged that clean drinking water and sanitation are essential to the realization of all human rights. Contaminated water does not only taste bad, it could be deadly. Water-related diseases affect more than 1.5 billion people every year. Unfortunately, there is limited awareness of the possibility of contamination in the residential water tanks, and more should be done to educate consumers on the importance of maintaining a hygienic water tank. In this paper a system is proposed to remotely sense, record, and report the quality of drinking water stored in residential tanks. The system sends alert messages to the landlord and the local authorities (if required) when one of the quality parameter is lower than the standard values.
