The need of water have risen exponentially to an unprecedented scale in India. The demand for water supply is ever increasing and satisfying this requirement has been a major challenge for many countries around the world. Ensuring access to safe and clean water is another issue that requires attention. In earlier days, the quality of water is high, but over the last two decades it decreases in terms of physical, chemical and biological conditions. This study aims to detect and control the contamination in water. It will monitor the pollution level in water continuously and it will generate the database automatically. This helps us to view the information at any time from the control board. The pH, turbidity and temperature level can be viewed through real time android application, which works under IOT. In the case of pollution accident on a river, it will alert the nearby water control stations by sending them notification through (Internet of Things) IOT to the registered mobile numbers.
