an opportunity to serve ganga
Under Namami Gange program, sewage handling projects are primarily being taken up in towns along the banks of river Ganga, through construction of Sewage Treatment Plants. These have long gestation period and usually take more than 3 years for commissioning since sanction, besides, being capital-intensive with high operation and maintenance cost. Since during the intervening period, sewage continues to flow into river Ganga and its tributaries, there is a need to manage the pollution load by ex-situ/ in-situ treatments through various innovative technologies(such as Modular STP based on Electrocoagulation, Filtration; Eco-Bioblock, Phytoroiad, Geo-Tube etc.) available across the globe. These are significantly less costly and require much shorter time duration of 6-8 months for commissioning and showing results. Implementing these techniques prevent degraded quality of water from flowing directly into river Ganga and its tributaries.
In-situ treatment is simple and easy-to-operate and does not require major modification of the drain. Naturally, occurring Microbial consortia/Nutrient media is used in the treatment process or activated to degrade sewage in flowing conditions without diverting the flow and no additional requirement of land or power is involved. The technology is considered to be cost-effective, relatively cheaper than conventional treatment methods, easy to handle and does not require skilled man-power to operate.
*Estimated budget is based on generic assessment (@ Rs. 2000/MLD for one year) for an indicative bio-remediation technology. Duration of treatment may change as per the conveyance of project proponent. The budget may vary depending upon level of technology and treatment proposed. This budget may also vary in case of modular kind of in-situ or ex-situ systems.
