I am from Surat and well ...

I am from Surat and well aware about Hyacinth and its carcenogenic side effects on population consuming such water.

Most of the replies below are well in line with the fact that River Tapi (& all Indian rivers) should be free from sewage and effluents. However the fact is that none of the towns and villages in the upstream of Tapi have a genuinely good waste water treatment system. People of Surat pay for in-sufficient efflorts of concerned upstream town - village authorities.

Along with Hyacinth removal, Mehulbhai, you also should intitiate for studies on increased incidences of Cancer in the city. This will confirm the fact that Hyacinth accumulates heavy metals and same are dispersed  when hyacinth decay in water body itself.

There can not be a single solution. SMC need to work out simultaneous set of holistic solutions wherein nutrient inflow is controlled, natural vortex aeration system ( stones which creat hurdles in flow are actually helpful for aeration of flowing water), competition for nutrients consumption in river etc.

We have technologies which can ensure 100% treated water discharged in the river, which can be implemented at rural & town level.  We also have systems which can raise DO level in river water.

We would be happy to be a part of SMC team to fight pollution and hyacinth growth if you wish.
