If there is magic on this planet, it is contained in water

- LORAN EISELY, The Immense Journey, 1957

About Water…

Page 2: Vanita Mohan -- Srithuli

� 70% of surface water reaches the Sea unharvested.

� By 2025, demand for fresh water would increase by 56%.

� Which implies, 2 out of 3 persons would face water scarcity.

Challenges on Surface Water

Page 3: Vanita Mohan -- Srithuli

� In 1957 – 231 villages were identified as “No Source Villages”

� By 2002 – 90,000 villages were identified as “No Source Villages”

� 1,57,900 villages have been declared as “Drought distress villages”

Lack of Sources on Water

Page 4: Vanita Mohan -- Srithuli

� 3 R’s – Reduce, Reuse & Recycle.

� Judicious use of fresh water.

� Adapting new technologies on agriculture. (like drip irrigation, sprinklers etc.)

� Roof water & Storm water harvesting.

� Reclaiming Sewage & Industrial effluents.

� Desalination near coastal regions.

Ways to enhance Water Resources

Page 5: Vanita Mohan -- Srithuli

� During 1970s Coimbatore district was declared as “Drought prone district”.

� During 1980s UNDP warned that Coimbatore District had the record of fastest depleting ground water level in the world.

� Still, we are one of the districts with highest number of borewells.

Coimbatore Scenario

Page 6: Vanita Mohan -- Srithuli

� Felling of trees.

� Poor Rainfall.

� Ground water getting dried-up.

� Tanks with poor storage facility.

� Contamination due to Sewage and Garbage.

Ecological Degradation

Page 7: Vanita Mohan -- Srithuli

� Indiscriminate Sand Mining.

� Pilferage and unauthorized borewells.

� Encroachments over water bodies.

� Blocking or Diverting water ways.

� Dumping of Solid Wastes.

� Letting in effluents into fresh water.

� Sewage getting mixed with potable water.

Misuse of Rivers, Canals & Tanks

Page 8: Vanita Mohan -- Srithuli

� Average rainfall data:- Whole of India is 1350 mm- Within Tamilnadu, it is between 950 and 1150 mm- Coimbatore is just 600 mm

� In the recent past, Coimbatore has witnessed decrease in rainfall like 670mm > 450 mm > 303 mm > 262 mm.

� Siruvani and Pilloor reservoirs hitting dead storage levels (80 MLPD against 18 MLPD drawn earlier from Siruvani).

Decrease in Rainfall

Page 9: Vanita Mohan -- Srithuli

Eco-conscious citizens of

Coimbatore coming together to

provide a solution.

All these led to …

Page 10: Vanita Mohan -- Srithuli

Project SiruthuliSiruthuli means “small drops”

A Non Government Organization that works towards bettering the environment

Page 11: Vanita Mohan -- Srithuli

� Founded by Corporates of Coimbatore.1. Sri Bannari Amman Group of Companies2. Pricol Limited3. Lakshmi Machine Works Limited4. Elgi Group of Companies

� Supported by the eco-conscious citizens of Coimbatore.

The Organization

Page 12: Vanita Mohan -- Srithuli

Four Pillars of Siruthuli

Page 13: Vanita Mohan -- Srithuli

Water Resources Management

i. Desilting of Water bodiesii. Noyyal Restoration

a) Formation of a Technical Advisory Committee

b) Encroachment Removal

c) Desilting of Chithiraichavadi Anaicut

d) Construction of Nandangarai Check Dam

e) River restoration through watershed concepts

iii. Roadside Rainwater Harvestingiv. Rejuvenating the Western Ghats

Page 14: Vanita Mohan -- Srithuli

Desilting Water Tanks

� 7 out of 9 tanks desilted.

� 808 acres of water spread area desilted.

� 20 kms of tank bund strengthened.

� Capacity to store 230 M.Cft. Water.

Tanks desilted:

1. Narasampathy Tank 5. Selvachinthamani Tank

2. Krishnampathy Tank 6. Periyakulam Tank

Noyyal Restoration

1. Desilting of Chithiraichavadi Anicut.

2. Construction of Nandangarai Check Dam.

3. Implementation of Madhvarayapuram

Watershed project.

Page 23: Vanita Mohan -- Srithuli

Chithiraichavadi Anicut …

Feeds water to 7 tanks located in the city through its 11.75 kms

channel

Desilted Area – 2 Ha

Page 24: Vanita Mohan -- Srithuli

� Ralegaon SiddhiCherrapunji – Rainfall 14000 mm – Water scarcityRalegaon Siddhi – Rainfall 400 mm – Fertile belt in Maharashtra through watershed concept

� Baba Seechewal

A religious man, restored the holy river “Kali Bein”from the state of a filthy drain to a pure sacred river. As the devotees cleared the river bed, natural springs started reviving one after another and very soon the river started flowing perennially.
