Tricky water hyacinth… any suggestions?

Water hyacinth is a very pretty plant to look at, but extremely difficult to get rid off. Apparently, water hyacinth spread so widely because people thought it was so pretty. Once it infests a water body, it basically explodes. Water hyacinth can double its mass within 5 days! Quite mind-boggling, I thought. Lots of water bodies are infested by water hyacinth with disastrous effects on the ecosystem and shipping. In fact the panama canal is also infested. Huge mowers regularly have to pass through the canal to make any shipping possible!

Our scope is related to the Valankulam tank in Coimbatore, South India. Siruthuli, the NGO we’re working together with, wants to control the water hyacinth growth in the tank so that it can be used for the fresh water supply of Coimbatore. Apparently, the water hyacinth thrives on the sewage water that is led into the tank. If you look at the tank on Google Maps you’ll see that the Valankulam tank looks almost entirely green!

Any suggestions on how to tackle the water hyacinth (incl. alternative uses) and smart treatment of sewage water are more than welcome!

  1. Hoi Lisa, what a challenge this will be!! But I am sure that you will enjoy it and together with the team will at least bring the locals a step further with managing their environment and controlling this hyacinth.
    Have a save journey and keep us once in a while informed on the progress and your experiences.

    Hi Lisa

    this is the link to the best/simplest way to book trains in India

  3. possible route:

    Delhi to Agra
    Agra to Ajmer ( Pushkar)
    Ajmer to Jaisalmer
    Jaisalmer to ? ( you will probably have to go back to delhi to go to Rathnambore , nearest station Sawai Madhopur,)

  4. Try to find a solution where you do not lose the beauty of the water hyacinth while getting rid of it. Maybe you can make them float in separate water ๐Ÿ™‚

  5. Lisa, why don’t you sell them if they are so pretty. Surely there will be a flower shop delighted with plants for free. ๐Ÿ™‚
