Buckingham canal in Chennai plays a crucial role in flood mitigation. It is rapidly deteriorating and needs immediate attention to avoid a repeat of last year's flood.

Long-time Kottur resident Narayanan’s earliest memories of the Buckingham canal are those of the famed salt and timber-laden wooden catamarans of the 1950s and the 60s. A namesake of the Duke of Buckingham and Chandos, the erstwhile governor of Madras, the canal was initially constructed as a brackish water-navigation channel in the early 1800s, connecting the north of Madras with Ennore. Additions were made till the end of the 18th century when the canal extended for over 100 km from the city up to Marakkanam in Villupuram district.

A significant number of the urban poor purchase water from tankers and those that deliver water in plastic cans, bottles, sachets, etc, incurring a sizeable monthly expenditure on water purchases.

In India, managing the current demand and planning for future water demand in urban areas is becoming a major challenge for urban water supply authorities. According to current figures by the World Health Organisation, 10% in urban areas in India still do not have access to improved water supply.

Urban planners have forgotten that lakes and waterways can only be altered by giving appropriate alternative means of storage and drainage. These water bodies must be revived.

The December 2015 rains in Tamil Nadu caused Chennai and its adjoining areas to be suddenly flooded. Huge portions of residential areas and roads were inundated for long periods of time. The rivers too flooded in an unprecedented manner, causing human loss and property damage to individuals, state and corporates. Looking at Irumbuliur Lake near Tambaram in Chennai, throws some light on the reasons for such widespread inundation.
