Smart water solutions for smart city are being considered today as the next campaign to makeover Indian cities to meet the challenge of future. The PM's idea of 100 smart cities in India is taking shape at grassroots levels.
Smart water is something which city assures to its people. This is clean water, supply and proper dissemination. Ajeevi at the fore of smart city solutions provides the technology solution of metered connection, 100% water leakage stoppage with 24x7 availability of pure water.
Ajeevi technologies, vision of a young entrepreneur,and was founded in 2012. Ajeevi pursues mission of social & environmental reform, that will not only ease life of a common man but also saves natural resources that are getting consumed in day to day activities. Several studies conducted on the subject have suggested various ways to make planet greener and save natural resources for future generations. This mission will make the cities smarter, and ease the life of the citizens.
Smart water solutions enhance quality of life of citizens from undertaking technology based rapid and proper provision of utilities. These utilities are modern, save energy and offer correct data on market price, demand, supply conditions and optimization of city resources like water.

Smart water is akin to smart city enablement which is happening in numerous cities of world. Across the globe smart water solutions provide access to clean water, proper drainage, water supply and utility of water. There are many smart water solutions which can be made better use of from existing resources for a city at disposal such that it can maximize to reach the citizens of a city. One of these concepts is the 'visibility of water flow’ through the water pipeline network.
This solution provides the city, the exact amount of water flowing in water pipelines in a city, at a given point of time. This is included in smart water by fixing the flow meters along the pipeline. Flow meters are bonafide sensors that measure the flow of water in a pipeline. They would easily transmit readings to a central server using various communication modes, which could be any one or a combination of radio and wireless protocols. When the attached flow meters are overlaid then the network shows actual number of flow meters varying as per city requirements. Later when the flow meters send back this data, this provides authorities to visualize water from pipeline networks. This is saved in a data repository. It is possible for city authorities to gather history of water flow in a specific pipeline. The above mechanism for water flow measurement is just one of the many solutions applied to smart water technology, although there could be many others. Some of the examples of smart water solutions are rainwater harvesting, a monitoring system , an integrated management etc. Usually the water consumption is collected to be transformed it into valuable and actionable intelligence across the utility.
In the example of sensors the stage of sensor deployment is followed by KPI for problem identification and mediation. The visual map of these readings is superimposed on the given city map. These are readings for individual flow meter or a group. A set of KPIs usually turns into a what is, a ‘Standard Operation procedure.’ Again the water that is pumped into the Water Distribution network but not reaching the customer is called ‘non-revenue water.’ In this we can observe equation for water flow from A through B and C.
Water flowing through A = Water Flowing through B + Water Flowing through C.
If the right side of the equation is less than the left side, it would indicate leakage or pilferage of water and would throw an alert causing a standard operation procedure. This comparison is called “Balance of Water”. Better accuracy of smart water solution can be obtained from smart water meters installed at every customer.
With an increasing pressure on water and clean water systems for innovation and integration in cities and townships the sustainable condition of extracting and handling water would continue for many more years. Once the smart water systems can handle these functions then it shall be clearer and more operational for urban planners. New ways of handling and using technologies for water management systems is coming to most cities at a low cost with changing new technologies as well. Use of innovative automatic handling, enabling critical processes, online and real time control for safer and effective operations is need of the hour. In integrated water network systems the use of sensors, for decentralized and diversified water treatment mechanism is significant and growing by the day. For the future planning one can easily ascertain thousands of such sensors working 24x7 with metered connection as well as 100% water leakage stoppage for pure and clean water.
High energy costs which are included with water increase with age and lead to potential impact from water shortage and increased consumption's. This has a more ill-effect on lifestyle and a more sustainable water supply is needed. Water with their associated utilities comes from having extraction made of clean and proper water drainage. In the easier terms rising prices would lead to expensiveness of water supply. There is combination of smart metering in tariffs encouraging customers to move from discretionary and high volume usage. This often becomes adhered to during non peak hours. While water utilities collect real time information from distribution based networks, it is more than just simple meter reading. Intelligence of using such networked information assesses cost reduction, leakage fixing, task field and transforming the water based operations in a reactive from proactive based nature. However the business related aspects of smart network concept is more innovative and integrative of the fissures and leaks in the system both manually and conceptually. Leading the errors and defect management is notionally stricter when the gauge of water cleaned and supplied is maintained for point of origin and point of supply. But as difficult as this is there is possibility of increasing efficiency from online and electronic devices which would be highly sought after in years to come. Till the time the dams are full, working to full capacity of plants there is lesser motivation to move ahead technologically but one can still make progress in areas of knowledge and efficiency in smart water supply.
