Abstract—Water pollution is a major global issue today. Indian media report says that significant quantity of municipal water samples tested in various cities were found contaminated with hazardous pollutants due to various reasons. Urbanization and industrialization had cause pollution to the clean water sources. Generally purified water is pumped from the source point of municipal water pumping stations to the households. But on its way, pollutants from municipal sewer lines & other sources get mixed in to drinking water distribution lines which causes serious health issues in urban areas. Hence this project mainly focuses on monitoring and controlling of pollution in municipal water supplies. Although the research of the water quality monitoring system is widely done and applied, the existing laboratory oriented “Stand alone Analyzer system” is still expensive, small coverage and not user friendly for domestic / field level WQM (Water Quality Measurement) purpose. Hereby, it is important to have In-Line water quality monitoring system that provides Real-time water quality data when the water is pumped in to the distribution pipe lines and storage devices. Here a low-cost, large coverage, user-friendly and Hybrid water quality monitoring and control system with multi-sensor which is based on Wi-Fi Technology is presented to assist both the consumer & municipal authority effectively.
Keywords—WATER QUALITY MONITORING,CONTROL

I. INTRODUCTION
In this paper the project of “Smart water pollution monitoring and control system” is aimed to monitor and control the spread of water pollution in municipal water distribution lines and household water lines. Here the water pollution is primarily monitored at consumer point & collected data are instantly reported to local municipal authorities for further analysis and action. In this hybrid system Real Time Water Pollution Monitoring system, water quality / pollution data such as TDS, PH, Turbidity etc., can be monitored on real time and viewed lively in mobile phones. Alert messages on water pollution can also be sent instantly to consumers / Municipal Water Authority. The multi-sensor circuit is designed to collect multiple data simultaneously. TDS/EC sensor, PHsensor, Turbidity sensor, Water level sensors, Low Pressure Fluidic Switch and Solenoid valves are incorporated in the system. The device is able to measure, collect and display the variants of the water quality and subsequently, the collected data is transmitted to the IOT platform via the Wi-Fi shield for real time monitoring. This innovative Hybrid RTWPM project developed for both Domestic and Laboratory use. The collected data is transmitted to IOT Cloud platform such as IOT, via Wi-Fi and can be viewed anywhere, anytime on Mobile Phones in real time. Implementation of various design and techniques used in this project prevents water pollution / contamination at very early stages of water distribution lines and thus eliminates expensive disinfection process in the water lines of municipality / households. Here the contaminated water is smartly diverted to the waste lines without affecting & contaminating all the tail lines. The motivation for this project is to reduce the cause of Water pollution across the world. Water pollution is a major global issue today. Media report says up to 20% of Chennai metro water sample tested were contaminated either with high biological contamination or had highly total dissolved solids. Mixing and contamination of sewerage water in the municipal drinking water pipelines is the main cause of water borne diseases. In this project of Smart water pollution monitoring and control system is aimed to solve and control the water pollution in municipal water distribution lines. Having monitored water pollution issues for the past several years in Southern part of Chennai we have come to the conclusion that this kind of issues to be eradicated with proper monitoring and control techniques. We have also found that the existing Stand-alone pollution monitoring devices used in metro water and other water quality testing laboratories cannot be used for monitoring the Real-time deduction of water pollution in the distribution lines and domestic connections. Hence there is a need for real-time monitoring of water pollution arises. Upon searching for suitable WQM instrument to solve the above said issues we found that there is no appropriate instrument commercially available so far in India. This situation motivated us to design and develop Real-time WQM using In-Line flow-through cells and Internet of Things based technologies.
