A duo in India have been spurred into action to fix pipes to conserve the water supply in Kolkata

There is light drizzle as Vijay Aggarwal and Ajay Mittal manoeuvre their two-wheelers through the labyrinthine alleyways of Kolkata’s Tiljala road slum. Early Sunday morning, the neighbourhood is teeming with activity – women sit on their haunches washing clothes and utensils; half-soaped children scurry in and out of their baths; towel-clad men wait to brush their teeth. Every 50 metres a community pipe gushes out water – plastic bottles, jerry cans and metal buckets are lined up to fill.

The duo along with their plumber, Ravi Shaw, who rides pillion, make their way to the first huddle of people and get to work. All it takes is a blow and twist of a wrench – the nozzle pops loose. Shaw fishes out an orange and white tap from his bag and fits it. While Aggarwal hurriedly plasters a Save Water Save Life sticker on to a lamppost, Mittal tells the people to close the tap once they are done and points out the helpline number on the sticker.
