By : M.S.Yatnatti Editor and Video Journalist Bengaluru : Reportedly BBMP chief engineer, stormwater drains, Bettegowda reportedly said: "We're prepared for rain. We won't have a situation like earlier.” The SWD network is 842km long, of which BBMP has remodelled 390 kilometres in co-operation with Bangalore Water Supply and Sewerage Board. The BBMP has requested the state government to allocate Rs 3,000 crore for maintenance, rebuilding and desilting of drains. The Bruhat Bengaluru Mahanagara Palike (BBMP) said the number of spots vulnerable to flooding in the city have been reduced to 26 from 362 identified initially, making it better prepared to handle rain crises. The number of such spots has been coming down.First reduced flood points to 226 and then brought it down to 96 in October 2017.” However, the pending ones were minor works and BBMP Engineers were confident of completing them soon. Most primary drains are being maintained and de-silting is being done often to handle excess flow of water.The drainage system is an essential part of living in a city or urban area, as it reduces flood damage by carrying water away. Fundamentally, the existing infrastructure and drainage system in the city cannot handle the excess water whenever there's a downpour. Originally, storm water drains in Bangalore were designed in keeping with the three valleys that run across the city Vrishabhavathy, Hebbal and Koramangala-Challaghatta. They served the purpose so long as the population of the city was within a certain limit. The unprecedented growth of Bangalore, unaccompanied by the necessary infrastructure, has precipitated problems of a large magnitude. The city drainage system comprises major drains which need to widenedas you are widening roads , roadside drains and shoulder drains need to be widened , otherwise all of which get overburdened during the rainy season and city may submerged like Chennai disaster happened recently.As you widen the roads at the same time you need to widen the drains to drain out the water outside the city . The drainage system is an essential part of living in a city or urban area, as it reduces flood damage by carrying water away. Fundamentally, the existing infrastructure and drainage system in the city cannot handle the excess water whenever there's a downpour..BWSSB should immediately stop sewage flowing in open storm water drains and Raja Kalve and Lakes . BWSSB BWSSB must have UGD for sewage disposal and it should not allow sewage to mix in open storm water drains and Raja Kalve and Lakes . BBMP has taken up road widening projects but never had taken up drainage widening and deepening projects. Thousands of private and BDA and BMRDA layouts came in but Size of road side drains never increased then where and how the water is drained out from Bengaluru. This oversight in planning will doom and kill the cities. Urban planners only given thrust on wide roads and fly over's without deepening and widening storm water drainage system which makes many urban cities to submerge during rainy season which result in loss of life and property. Be it the impact of climate change and global warming or something else, we must be prepared for changes in temperature and untimely rain and floods. If BBMP wants to avoid Mumbai and Chennai like disasters it has to woke up and create new drainage systems to entire Benagaluru city.
