Water evaporation reduction from lakes
- 1. Pani Ka Bharosa Ya Bharose Ka Pani
- 2. Monsoon Rains give India Enormous, Assured, Water as a part of water cycle, owing to Evaporation, from Tropical Ocean Every year between June - Sept .
- 3. Evaporation also takes away huge water from storages Ground Water is often unreliable, expensive, and contaminated
- 4. Managing year-round needs, on stored water, is a challenging task. Only Solution Manage Existing Water wisely and Maximize utility
- 5. Three Steps towards Total Water Security Water Assessment Adequate Storage Creation Preserve Stored Water Present subject matter “Stored Water Preservation”
- 6. Being invisible and slow, Evaporation is rarely taken Seriously More than 70 % India is Hot, Arid for 8-9 months Annual Evaporation column, in major area is around 2500 to 3500 mm per year
- 7. Evaporation Reduction is being effectively done, All over India , since 1983 by using Evaloc
- 8. Recent Project Details - Tidi (HZL, Jawar) Evaloc Application – March / July - 2009
- 9. 2008 - Rains were deficient, Inflow was less, Water in Tidi had to be conserved. Reducing Evaporation loss was only option Evaloc was used to reduce Evaporation
- 10. White objects are Evaloc Bags, attached to flagged, anchored floats Evaloc spreads Continuously, Uniformly Ratio - 1 Float : 1 Hectare Surface Water Surface - 70 Hectares Approx . Water saved 35% ( average)
- 11. Novel Evaloc Spreading Technique ( SR - Sustained Release Method) Ultra thin Evaloc film is visibly evident on water surface, granting mirror like finish, not observed anywhere, usually.
- 12. Evaloc emulsion is self-spreading over water surface of stationary water body Ultra-thin film retards escape of surface water molecules into open atmosphere, thus reducing evaporation
- 13. Evaloc is Non-Toxic, vegetarian, Biodegradable, and 100% safe for living beings
- 14. Performance History Since 1983, Evaloc has saved 9 billion liters (9 mcm) water from over 100 lakes, Dams, etc.
- 15. Evaporation Measurement with Class ‘A’ Type Pans In India ‘Model Pan Factor’ is considered 0.95 (Water column being observed by PHED, Raj., Govt. Officials)
- 17. Past Performance 09. Hin. Zinc Ltd.- Jawar and Agucha Mines, Raj. 10. Nagarjuna Fertilizer Ltd.- Andhra Pradesh 11. Kirloskar Ferr. Ltd. - Hospet 12. Mukand Steel Ltd. - Hospet, Sirguppa 13. JK Tyre Ltd. - Kankroli, Raj. 14. JK Laxmi Cement Ltd. - Sirohi, Raj. 15. Novartis, Syngenta Ltd. - Goa. 16. Gandhi Agro. - Vafgav, Maha Evaloc is repeatedly used above.
- 18. Evaloc - Cost Benefit Details Evaloc reduces 30-50% evaporation At 40% average saving, cost of 1,000 lit. Water = Rs.3/ ± 10% all incl .
- 19. Evaloc Usage - Area and Period Evaloc is effective on any stationary water (Largest area covered by us, so far is 650 Ha.) Evaloc usage is most cost effective during dry period, around 200 days every year
- 20. Evaloc - Fact File Product - Fatty Acid Compound Purpose - Reduce evaporation with chemical Safety - 100% safe for living beings Utility - Effective on small, large surface History - 9 mcm water saved since 1983 Cost - Water saving cost 1,000 lit.= Rs.3/- Efficacy - Proven track record over 100 tanks
