Urban storm water drainage systems have got priority in India only after drinking water supply and sewerage projects in majority of the cases. Due to fast pace of urbanization and migration of people from rural areas to urban areas in quest of livelihood and better education, there has been immense pressure on urban infrastructure, worsening the problem of urban drainage systems in India. Urban floods are the floods occurring in urban areas, and are primarily caused by heavy rainfall overwhelming the drainage capacity. The megalopolises (mega cities) have a long history of municipal drainage perceptions since the British era. Most of the underground drainage facilities within core clusters of these mega cities are usually century old antiquated brick masonry conduits. The existing storm water collection network in these cities is mainly designed to serve as a combined system for sewage as well as storm water runoff. Augmentation and rehabilitation including separation of storm water from sewage in such facilities invite highest level of challenges for municipal engineers and financial resources.
