WATER ATM SYSTEM USING PLC

Abstract

This proposed automated water distribution system is used to distribute the required amount of water from
ATM machine. We provide ID & PASSWORD to each user then user will enter the required amount of water, So it will
help for billing in future. The water from storage tank is measured with the help of level sensor. This system consists of
PLC and SCADA. PLC is used to control the distribution of water. SCADA is one of the emerging technologies which are
used for complete monitoring. The overall system is connected to PLC with the help of Ethernet cable. PLC gives the
signal to the solenoid valve according to the level from water storage tank. What started as a pilot has now gradually
begun to gain ground with orders from a number of state governments, pilgrim centres, and public places. “This is not
just another business initiative but a social enterprise, whose focus is on creating a viable business model and grooming
youth to become entrepreneurs manning these water ATMs, and helping people quench their thirst,” says Parag
Agarwal, Founder and CMD. Explaining the concept, he says the water ATMs are a combination of appropriate
technologies required to treat the water available at different sites. The company’s Supremus Aqua Water Treatment
System have been used to make the filtration and purification process efficient. Dually operated on solar energy and
electricity, they can be remotely maintained and managed. JanaJal has the ability to eliminate the wastage of water
during treatment for all river and municipal sources, while for water from bore wells the wastage is limited to around 30
per cent. Each water ATM has an estimated lifespan of 10 years and a capacity to dispense up to 15,000 litres per day.
Dispensing drinking water in quantities such as 250 ml and 1 litre at Re 1 per litre on a refill basis, people are
encouraged to take away larger quantities for the consumption of their families.
