Punjab province is set to launch an innovation for water-short Pakistan: Solar-powered ATMs that dispense clean water when a smart card is scanned

The two-foot-square prototype machine looks and functions like an ATM, but dispenses water instead of cash. Users are issued a card they can use to claim a daily share of water.

The project, a collaboration between the Punjab Saaf Pani (Clean Water) Company and the Innovations for Poverty Alleviation Lab (IPAL), a research centre in Lahore, aims to install a water ATM on each of a series of water filtration plants being established in rural and urban fringe areas of Punjab province.

The machine is designed to help the government cut water waste and ensure people have access to clean water, said Jawad Abbasi, a programme manager at IPAL.

"The innovative machines will help the government maintain a record of the exact quantity of clean drinking water being dispensed in a day in a specific locality, besides ensuring its quality," he said.

The quality and quantity of water being dispensed will be tracked in real time online, through a central server, he said.

HOW IT WORKS

The devices play an audio message upon authentication of a scanned card, after which they dispense water for the user. Green and red buttons enable the user to start and stop the flow of water.

A flow control meter manages how much water is dispensed, and sensors measure the amount of water still available.

In its first phase, the project will cover three districts of Punjab including Bahawalpur, Rajanpur and Faisalabad, all areas with particularly serious water contamination issues, experts said.

Each beneficiary family will be entitled to collect a maximum of 30 liters of clean drinking water daily from the filtration plants with their unique identity card, Abbasi said.

"We are planning to install the machines at 20 filtration plants in the first phase that will benefit some 17,500 families," he said.

He said that his organisation was seeking $23,500 in aid from the UK Department of International Development to put the prototype into production and install more of the dispensing machines at existing water filtration plants in Punjab.

Similar card-based water dispensing systems are already in use in neighbouring India.
