Delhi Govt and DJB first must stop flow of raw sewage/ Untreated effluents coming in to Delhi state from neighbouring states and seek legal enforcement of suitable treatment of influents as neighbouring states do have land resources and legal obligations. Rather than planning for compact STPs with full accountability for treated effluent Waste water, it is flawed logic to say that Land is costly, so, Bio Remediation by Floating Reed bed shall be attempted as low cost intervention. STPs take much lesser space while huge land area shall have to be brought under Reed Beds and Govt. shall have no control on Reed bed Lands harbouring pathogen carriers or disease vectors besides foul smelling gases getting generated and spreading in the localised environment. It also has potential of allowing Heavy metals and toxins percolating deep into u/g aquifers isolated or connected to River systems. A rethink is required. Why can DJB adopt more safe and lower economic cost options rather than pulling wool over its eyes by accepting and propagating twisted technical logic.

Thanks Mathew. Authorities must rethink and not waste time and resources in options which do not address the real requirements and are likely to allow continuation of permanent damage to aquifers and habitat around. All technological innovations should be deployed. Even before a Consultant is awarded a job to present a plan, how can authorities comment in favour of any option?

I find it very hard to imagine what a reed bed treatment system for Delhi would be like for all the reasons you have mentioned Lokesh! These systems also require some maintenance but the land area required would be enormous.
