After a brief interval, the north-east monsoon made its presence felt through the cyclonic storm Vardah, terrorising both coastal Tamil Nadu and Andhra Pradesh.

Chennai’s disastrous December run continues for the second year in a row. While the devastating flood of December 2015 remains etched in the city’s collective memory, cyclone Vardah was no less scary and did not lag behind in its severity.

Chennai’s topography, along with civic apathy, official lethargy and a complete disregard for its natural floodplains see the city reeling under severe waterlogging every year.

Chennai’s drainage system--both natural and man-made--is unparalleled. Three rivers flow through the city--the Kosasthalaiyar to the north, the Cooum cutting right through the centre and the Adyar to the south; around 16 major drains criss-cross the metro in addition to the mammoth Buckingham canal along the coast. Around 2000 km of micro drains flush stormwater out in addition to the Ennore creek and the Pallikaranai marsh. “What more does a city need?” remarks professor S. Janakarajan from the Madras Institute of Development Studies (MIDS).

Hello

My home was constructed in the year 2000 having only ground floor (2BHK) so I planned for a septic tank for black water and soak pit for grey water. in 2008, I have constructed the first floor (3 BHK) in which I stay. During that construction, we have not made any change in septic tank and soak pit.

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.
