THE SUCCESS OF Bellandur and Varthur Lake Rejuvenation WILL DEPEND ON:
Good governance (too many parastatal agencies and lack of co-ordination).
Digitisation of land records (especially common lands – lakes, open spaces, parks, etc.) and
availability of this geo-referenced data with query based information system to public
Removal of encroachment of lakes / wetlands, lake beds and storm water drains (connecting
feeders) after the survey based on reliable cadastral maps;
Restriction / Preventionof the entry of untreated sewage and industrial effluents into lakes;
Decentralised treatment of sewage (preferably at ward levels). Letting only treated sewage into
the lake (as in Jakkur lake model);
Removal of nutrient rich sediments – to enhance the storage capacity, improve groundwater
recharge, to minimise further contamination of treated water, etc.
Ban on use of phosphates by appropriate agency in the manufacture of detergents may be
examined as it will minimise frothing
Regular removal of macrophytes (Eichhornia sp., Alternanthera sp. etc.) in the lakes
