Sewage pond called Mansarovar
To restore Shahpura lake, also known as Mansarovar, Bhopal Municipal Corporation must innovate its sewage treatment system UrbLanakes
THE MUNICIPAL authority of Bhopal is scrambling to save the image of the lake city, literally. Since September last year, they have been frantically removing sludge,algae and water hyacinth from Shahpura lake,one of the most polluted lakes of Bhopal.They are also installing metal mesh around the lake to prevent plastic waste and other debris from entering into it.The lake will regain its glory by April 2016, claim officials of the Bhopal Municipal Corporation (bmc).
Shahpura lake, also called Mansarovar, came into being in 1974-1975 after an earthen dam was built near Chunabhatti village in the southern part of Bhopal under the Betwa irrigation scheme.Surrounded by hillocks,it became the third important lake in Bhopal after the Upper and Lower lakes. People started depending on it for drinking water, irrigation and pisciculture. Within a few years,housing colonies replaced the hillocks and encroached the lake’s catchment area, spanning 8.29 sq km.By early 2000s,the lake turned into a sewage pond. People living in the surrounding areas repeatedly complained of the stench to bmc but to little avail.bmc’s recent attempt to clean the lake began following an order by the National Green Tribunal (ngt),which was hearing a petition by Bhopal-based environ- mentalist Subhash Chandra Pandey in 2011. Pandey had stated that the lake water has been severely contaminated by raw sewage.
Laboratory analysis of the lake water gives credence to the complaints.According to Madhya Pradesh’s Bureau of Designs for Hydel and Irrigation (bodhi), biological oxygen demand (bod) of the lake water was 19.2 mg/liltre during 2011-12.Going by the standard set by the Central Pollution Control Board, water with such high bod level is not suitable even for bathing.
