Restoration of Water Bodies

Sustainable solutions for restoring water bodies to their pristine glory.

Many rivers, estuaries, lakes, ponds and other water bodies across the globe are victims of urbanization and are polluted beyond their self-recovery capacity. Uncontrolled dumping of garbage, debris and sewage into water bodies leads to an influx of various pollutants including organic compounds, phosphates  and nitrates, thereby adversely impacting the water quality. These pollutants lead to eutrophication of ponds and lakes by boosting growth of algae and undesirable weeds like water hyacinth. Excessive algal growth, in turn, interferes with penetration of light and also leads to reduced dissolved oxygen levels in water bodies, thereby hampering the growth of other aquatic organisms and disruption of the balance of the aquatic ecosystem. Due to reduced dissolved oxygen, anaerobic degradation of organic matter takes place, which leads to the production of foul-smelling gases like ammonia and hydrogen sulphide, causing odour issues in the vicinity.


Effwa offers its expertise in sustainable restoration of various polluted water bodies like lakes, ponds, estuaries etc. for reversing the adverse impacts of the pollutants by bioremediation technique. Bioremediation is a treatment process in which the affected water body is restored by in-situ application of selective biocultures (yeast, fungi or bacteria) or their consortium to degrade accumulated complex organics and other hazardous substances into less toxic or non-toxic end products. Team Effwa has demonstrated its capability in the field through some of the most challenging projects including the case of restoring over 300 years old mid-water temple and complete beautification of lake and its surroundings.
