A project of Siruthuli: Waste get watered with EM solution before dumped on the dump site. With help of Effective Microorganisms (EM) waste rottens quicker.
Next generation grassland? Hope not. Actually due to EM technology it doesn’t smell very badly.
The lagoon next to the dump site. From here the sewage water of
Open drainage system. Very problematic!!! Since nobody can control the let-ins of industrial wastewater.
Sewage collecting point from here the sewage water gets pumped up to the Lagoon, or hopefully soon to the new sewage treatment plant (opened Jan 2011)
The sewage treatment plant, unfortunately only 30% of

The Siruthuli team is looking into new ways to treat wastewater in Coimbatore. Does anyone have any information about designing/building a wastewater treatment plan in or next to a hospital in order to treat toxic waste?
How is hospital waste water treated in your country? how much does this system cost? What are the components?
We are new to this field, so any help would be greatly appreciated!!!

Siruthuli was founded into 2003 due to poor water situation in
Siruthuli’s first mission was to bring the ground water level back up. To achieve this goal one of their initiatives was to revive the historic water tank systems. Siruthuli revivalized 9 water tanks and the cross linking channels which lead water from the Noyyal river to and between the tanks. (For further activities by Siruthuli please visit their webpage: www.siruthuli.com).
Over the time a new problem emerged.
Are the sewage water and the growth of the water hyacinth related?

- Asexual reproduction: Water hyacinths are building daughter plants within every fifth day. This makes them double their size within round about 12 days
- Floating plant: Water hyacinths have air in their leave stems and their roots are only hanging in the water. If they run out of space, they just sail away.
- Growing in thick mats (up to two meters): The mats are causing a lot of problems, reducing light and oxygen; change water chemistry; clogging intakes of irrigation, hydropower and water supply systems; restraining shipping and fishing and at least the mats making it difficult to harvest.
- 1-1,5 mm egg shaped seeds:The seeds can last in mud or soil about 20 years. When they reconnect to water they start growing again
- 95% water: with their transpiration water hyacinth reduce water from water bodies which are 1,6 % higher then normal evaporation
- calm and slow floating water
- temperatures between 28- 30 degree Celsius, good growing between 22 degree Celsius -35 degrees

Siruthuli is asking us for a strategic plan regarding the water hyacinth growth in the Valankulam tank. This tank is essential for providing Coimbatore with water for irrigation, washing and other secondary uses but has been heavily infested with water hyacinth. The growth of this aggressive plant is boosted by various sources of waste water flowing into the tank.
Throughout our assignment we'll be posting on this blog regularly. Feel free to follow us and leave comments!
We're looking forward to working with Siruthuli on this exciting challenge.
