Once known for its network of lakes that helped manage excess rainwater, Bengaluru has seen many of these water bodies encroached upon.

Some people still walk hours each day to collect water from jagüeys – reservoirs filled with rainwater.

Beyond the vegetable beds is a planting area of native shrubs and grasses to provide additional habitat and permeable surface to collect rainwater.

But almost all pumping stations and treatment plants operate under an environmental permit which specify that they must process or "pass forward" a certain amount of sewage and rainwater before spilling starts.

England, like much of the world, has a combined sewage system meaning that rainwater and sewage share the same pipes.
