Understanding Stormwater Drain Typologies

Stormwater drains in Bengaluru run through a diverse range of urban conditions—cutting across built-up areas, roads, private plots, parkland, and open spaces. These adjacencies influence the flow, function, and vulnerability of each segment of the network.
