Scenario
By year 2050, the global demand for water will rise 
by 55%. The 2015 report by United Nations World 
Water Development projects this rise across the 
various sectors.
India’s economy also critically depends on use and 
management of water for agriculture, industry and 
domestic consumption. Recognizing this 
dependence, the Ministry of Water Resources plans 
to invest significant funds into management of 
water and wastewater sector.
Some of the aims of good water resources 
management are:
• Improve of water quality 
• Improving energy efficiency while 
managing and treating water
• Minimise leakage and wastage 
• Conservation of resources
• Reducing downtime and operating costs

Infrastructure for Water Treatment
• To supply quality water in the desired quantities, a typical city may have more than 20 to 30 Water Treatment Plants (WTP's). At the 
discharge end, for treating used and polluted water, the city may have an equal number of Waste Water Treatment Plants (WWTP's). 
• For optimum efficiency and speed of response, a Centralized Control and Monitoring Station supervises all the equipment and 
processes of plants from a single location. This Station accepts numerous inputs from all the plants to deliver real-time corrective 
responses to the changing parameter and conditions. As an upgrade, tech-savvy Municipal authorities now demand a cloud-based 
solution for supervision of all the water treatment facilities.
High-technology automation solutions conforming to industry standard protocols are 
essential to implement the future needs of the water treatment plants.

Challenges of Water Supply System
The Criteria for Water Treatment Process Are:
• Flow of raw and treated water along with dosing of treatment chemicals
• Monitoring of water pressure at upstream and downstream location and at critical points 
• Monitoring levels in rivers, wells and reservoirs   
• Disposal of sludge
• Monitoring of temperature for motors, bearings and valves
• Dosing of Fluorine, Chlorine and Calcium
• Monitoring turbidity and water quality
Water Treatment domain consists of several critical processes that can 
benefit from high technology automation for delivering consistent 
results.
