For the past few days people driving along Tank Bund or Necklace Road or coming to spend an evening along the shores of Hussainsagar have been subjected to stinking smell from the water. The foul smell is due to algal boom in the lake.
Due to rising temperatures, there is a rapid increase of algal growth as well as weeds in the polluted waters. The foul smell is a mix of chemicals, sewage and industrial effluents.
The Buddha Purnima Project and Hyderabad Metropolitan Development Authority officials said that foul smell emanating from the polluted lake is a common phenomenon during summer when temperature rise and triggers growth of algae.
Though the authorities said the water quality in Hussainsagar has improved, experts say that in summer, the concentration of waste in the water increases, leading to the stronger smell.
It may be mentioned here that the HMDA has taken up cleaning of the lake under Hussainsagar Catchment Area Improvement Project with financial assistance from Japan International Cooperation Agency (JICA) at a cost of `370 crore.
