Was really fun and another good insight in
For our final presentation, Siruthuli were spreading the news and invited their trustees, APEXmembers and volunteers. When we started our presentation there were about 25 people in the audience. When the light was switched on at the end there were about 40 people.
We talked about the as is situation which we discovered during our field trips.
We needed to disillusion a bit since there is no one time solution for the water hyacinth. The only option left is to combine different control strategies and to adjust them to the local situation and facilities in
One hour before our final presentation we met Prof Dr. Kalyanasundaram, from the Institute for Entomology, Tamil Nadu Agriculture,
We recommended not to do anything about the water hyacinth at Valakulam tank for now. With the current volume of daily sewage inlet the growth rate of water hyacinth is too excessive and the harvesting effort would be a waste of money and real a Sisyphus operation. Actually at the moment water hyacinths have a positive effect on the water quality of Valankulam tank since the plant has the ability to treat sewage water.
We recommended starting water hyacinth control at a medium or low invested tank, to prevent the tank to become as bad as Valankulam and to test the new control strategy. We recommended a combination of biological and manual control were we also highlighted options to make harvesting smarter and less cost intensive. As usage option we recommended to make briquettes out of the water hyacinth. These can be used by dwellers for cooking and replace the firewood. Getting firewood gets more and more hard the faster the city grows.
In parallel a thorough water analysis needs to be carried out. Only on basis of water analysis results a sound decision can be made how the sewage water of Valankulam should be treated. For this experts and funds will be needed. We recommended Siruthuli to build knowledge partnerships and to start applying for funds. We did an in depth research of possible partners and were already able to establish first contacts. Now unfortunately our time is over. It is time for us to say good bye and start packing. We hope that Siruthuli will be successful, so that we can come back soon and take a swim in Valankulam tank.
Drivers in
To our very surprise there is one situation where nobody blows the horn: Driving against traffic.
We couldn’t believe what was going on when we drove the first time back from the office to our hotel. Driving from the office lane we got onto the main road in the wrong direction. After a while we got prepared but every time it was a surprise again. Driving against traffic is just a common practice here to take a shortcut. It seems to bother nobody in
All three of us were really impressed how Siruthuli celebrated the 80th birthday of Dr Kalam.
The program was a good combination of celebrating and making environmental statements.
The Ex-president of
He was seated on a swing a symbol for happiness in
At the end Dr. Abdul Kalam made a very encouraging speech to all the school children reminding them about their responsibility for a better life and better environment for them and their community, for
During the birthday lunch the three of us got surrounded by a class of school boys, which became so exited, and made us feel like movie stars. Everybody wanted a picture with us. We gave autographs and signed invitation letters, school books and in case of paper shortage real hands.
The TV and the News will be there. Lisa and I
went to the tailor to get dressed up for such an honourable event. What you think? We are really looking Indian now!
Unfortunately there is no option to get rid of water hyacinth, the only option left is to control their growth: The cleaner the water the more the growth of water hyacinths slows down. So it would be a big achievement if no sewage water gets into the tank.
Currently the government of
However Siruthuli and the 25 NGOs are having doubts if the target date will be achieved or even worse that the project will never be completed due to corruption. Their idea is to build a decentralized sewage treatment plant which collects and treats the sewage streams floating into Valankulam tank. The following steps are needed:
However the water hyacinth problem exists
The only option remaining at the moment is: Harvesting. Harvesting of water hyacinth is time consuming and cost intensive.
So the big question is: HOW CAN WE MINIMIZE COSTS? HOW CAN WE MAKE THE HARVESTING PORCESS AS EFFICIENT AS POSSIBLE?
What needs to be done:
Typical harvesting and transportation problems:
Hyacinth tends to float away, when manually harvested from banks. Due to their high percentage of water (95%) they are heavy to lift and are of high volume.
Problem through sewage contamination: due the high sewage water concentration in Valankulam tank the water is dangerous to health. Physical contact with the water needs to be avoided
Any idea, any creative thinking?
