Arun Lakhani and Urban Waste Water Management
Posted on July 22nd, 2016
Urban wastewater management has grown to be a challenge in India as infrastructural development and regulations have not kept pace with population growth & urbanization. Annually more and more people are moving into cities, and the figures are expected to reach about 600 million by 2030 making India more peri urban than urban. Already, there is enormous pressure on planners to provide utility services, and water supply is a priority, particularly where peri-urban water is exported formally or informally to fulfill city requirements. At the same time, the urban return flow (wastewater) also increases, which is usually about 70-80% of the water supply. The challenge of the growing Indian economy is that, in many cities, the wastewater generated is a mixture of domestic and industrial wastewater which makes risk alleviation and reuse recommendations a challenge. Lack of systematic data on the different discharges makes it difficult to estimate the volume and quality of wastewater discharged and the total area under (usually informal) wastewater irrigation. Arun Lakhani firmly believes as a nation we need to tap into the Waste Water Treatment and Sewage Water Treatment for sustainable living in India.
Vishvaraj Infrastructure Limited (VIL India) spotted the following opportunities in the Waste Water Reuse Opportunities. Namami Gange Program. Ganga authority is planning to create treatment facility for 12,000 MLD of sewage and 3,000 MLD of industrial effluent. Reuse of the treated water is part of the program. Reuse for the power plants and industries. Power plants across India are hypothetically to use treated water, if sewage is available within 50 kms in the vicinity of power plant. Governments of Rajsthan and Maharasthra have taken the lead.
