The increased population and urbanization in Srinagar
city has resulted in an increase in the discharge of domestic
sewage into the water bodies especially Dal lake, due to
which the lake has undergone tremendous changes in
its chemical, biological and trophic status. So there is an
immediate need for trapping these pollutants before
releasing into the lake. It was in this background that
wastewater treatment plant was installed at the periphree of the Dal lake at Hazratbal to treat the wastewater coming
from Hazratbal area and University campus. In past, no
extensive study has been carried out to assess the efficiency
and quality of these STPs. Because of the associated dangers
of sewage, present study was carried out to investigate
the impact of the wastewater effluent discharged and to
estimate the removal efficiency of STPs around the Dal
lake. In addition, seasonal change in the removal efficiency
rate was evaluated.
