By: M.S.Yatnatti: Editor and Video Journalist Bengaluru: 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.

Drainage system : As there is urgent need to big new drains need to constructed to drain out the storm water outside Bangalore .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. 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. Design New Drainage for Bengaluru: Flood risks and drainage are key considerations when planning all new suburbs. Today, underground drainage systems are generally designed to cope with frequent storms - those with a 20% chance of occurring in a year. Any excess water travels along planned overland flow paths that carry water away from properties. This prevents them from flooding in the majority of storms - up to those with a 1% chance of occurring in a year.We also look at other benefits when designing drainage systems, including the impact on rivers and creeks. For example, when building drainage inBengaluruwe also need to installgross pollutant traps, which capture large litter items like plastic bags, bottles, newspapers and cigarette butts to prevent them being washed into rivers and creeks. We need to createBasin to include a wetland to improve storm water quality, provide greater flood protection, and allow storm water to be harvested to water harvestingopen spaces. Entering storm water drains is dangerous and illegal, and could cost you your life or endanger others who rescue you. What's required is a comprehensive approach to the problem, which essentially involves putting in place a new widened sustainable drainage management system as in developed countries. A storm water drain renovation and widening and deepening and management project had to be prepared for Bangalore andimplementation it without delay. In the meantime, risk assessment of vulnerable areas must be carried out and corrective measures taken to minimize them.
