Better water quality for sustainable future urged
The key speaker included Dr Xavier Swamikannu, US Fulbright- Nehru Environmental Leadership Fellow, Central Pollution Control Board, New Delhi, India and Faisal Nadeem Gorchani, Coordinator Policy Advocacy and Outreach gave opening remarks.
Dr Xavier Swamikannu, an expert on regulatory control of urban water pollution delivered a special lecture on “Sustainability concepts for water quality protection” . Dr Xavier explained the `Stormwater Runoff Pollution’ which is produced from a developed landscape during storms.
He maintained that it accumulates and transports much of the collective waste of the urban environment into surface water sources and becomes the primary source of impairment in rivers, lakes, and estuaries. “This urbanization has altered the hydrological patterns and a radical difference has been observed in water flow regimes after the urbanization, Dr said.
He cited some of implications of urbanization on water quality such as loss of water-retaining and vaporization functions of the soil and vegetation in the urban landscape. He also proposed measures for water quality protection and to better manage water pollution in urban environments.
He suggested nonstructural controls such as better site design, retrofitting, downspout disconnection and conservation of natural areas to dramatically reduce the volume of runoff and pollutant loading from a new development.
He emphasized on to control pollution at the source rather than to treat regionally. He also urged to promote aquatic resource conservation design during land development to maintain redevelopment hydrology. During the question-answer session, the participants urged that Capital Development Authority to learn from the North American urban water management experiences.
