The treatment is done in two stages:

  • The conventional sedimentation, filtering and chorine treatment are given. 
  • The biologist developed a series of six connected marshes over 60 hectares of marshland. 
  • Appropriate plants, algae, fungi and bacteria were seeded into this area, which neutralize, absorb and assimilate the pollutant. 
  • The water flows through the marshes, it get purified naturally.
  • The marshes also constitute a sanctuary, with high level of biodiversity in the form of fishes, animals and birds that now reside there.
