The problem of getting rid off and treating water hyacinth can be carried out in a systematic manner as below:
- Stop the sewage flowing into the river. In the portion upstream of the water hyacinth.
- Introduce Chinese or any other carp fish into affected portion, after consulting the fisheries department. This fish likes to eat the water hyacinth and can also purify the water to some extent. This can be also sold in the market after getting it tested for any damaging effect.
- Some of the water hyacinth can be taken out and treated for producing bio-gas and manure. Other green garbage and cow dung could also be mixed with it. Even sewage could be treated along with it.
- This would have to be carried out over a long period to make it economical.
- This method was tried in Kota in the Chambal River and has also been tried by the Chinese many years back.
