Rows of men and women are gathered in its narrow lanes, some sitting on their haunches. Large plastic drums are placed strategically in front of them.
Suddenly a cry goes up: "It's here, it's here."
A water tanker backs into the lane, and the place descends into chaos.
Young men charge towards the truck, clambering onto the top with pipes, which are then lowered into the tank. Others push the drums in place - there's a mad scramble to fill them up with clean water.
