PANEL DISCUSSION ON “RAIN WATER HARVESTING & SUSTAINABILITY

OF WATER SUPPLY”

Dr. Santosh Deshmukh, Senior Manager( Sustainability), Jain Irrigation Systems Ltd., Jalgaon 425001 Maharashtra)

Phone-0257-2258019, Mobile No: 09403080103 Email: [email protected]

Suggestions and Recommendations

For sustainable water supply for cities following suggestion and recommendations are made:

1. Water shed should be the base for rain water harvesting and supply of water for small cities. (River Basins for large cities and big industrial clusters)

2. Efficient water used at up stream for agriculture will release the pressure for down stream water supply for cities. (drip irrigation!)

4. Sufficient area should be provided for water bodies, alike for gardens and playgrounds in cities and towns in arid regions.

5. Proper utilization of treated waste water for peri urban agriculture, lawns and gardens of the cities should be on the agenda.

6. The water quality has to be maintained for upstream, down stream, treated waste water and water bodies of the cities.

7. Good agricultural practices at upstream will not affect the water quality and quantity for the water used in cities and towns

Policy, legislation and obligations

• Water foot printing approach for different users of water and charges based on slots.

• Financial instrument like Water Certificate Mechanism like REC for water harvesting for building and obligatory for those not harvesting.

• Water savings plumbing devices should be made compulsory for new buildings : including shower heads, faucets, aerators, toilets etc., (in 1990’s NYC reduced the per capita water consumption from 187gpd to 125 gpd).

• Each city/ town have to choose their own way of solving problem of sustainable water supply , any attempt to dump the idea which worked elsewhere should be avoided.

Water audit to be mandatory for cos.

Ashish Sinha: New Delhi, Jan 06 2013, 00:09 ISTMove aims to encourage companies to follow best international practices; violators to be penalized

After tax audits and mandatory corporate social responsibility norms, the government is set tointroduce water audit and yearly water footprint disclosures in annual reports a mandatoryfeature for companies. The move is aimed at encouraging companies registered in India to adoptthe best international practices on water use efficiency.

A senior official said the idea is to make it mandatory for companies to disclose the volume offresh water used by them in their production activities and the volume of recycled water use peryear. Firms will also have to commit themselves to timelines on reducing their water footprint.“This would be implemented through the corporate affairs ministry soon,” said the official.

The corporate water footprint is defined as the total volume of fresh water that is used directly orindirectly to run and support a business. The water footprint of a business consists of water usedfor producing/manufacturing or for supporting activities, and the indirect water use in theproducer’s supply chain. This will now have to be disclosed every year in the company’s annualreport

Jain Irrigations Experience

- 24 X 7 Supply is sustainable water supply for house hold

- On demand irrigation in canal command area

- Drip irrigation for lift irrigated water saves

- Piped conveyance of water for agricultural use

- Saves water- energy- cost and increases food production

Present :Un-Sustainable water supply

Intermittent

Irregular

Leakages

Possibility of contamination

Low supply pressure

Free of Cost or Fixed Cost

Tendency of public

Maintenance results in stoppageof water supply for entire ward

No Leakages in the network

No Contamination of water

Assured Water supply to all levels of society

Negligible Wastage of water by public

Unauthorized connections can be restricted

Consumption reduced - effective use of water

Pay As You Go charging basis

Regular Revenue Generation

ULTIMATELY - Customer is HAPPY

Hence 24x7 is a “Safe, Reliable and Affordable

Water Supply & Distribution System”

“By using HDPE pipes”

24X7 : Sustainable continuous water supply with constant pressure

Water consumption is reduced by 40% to 50%

Operation and Maintenance Cost is reduced by 30% to 40%

Revenue is increased by 4 to 6 times

Safe, Corrosion & Contamination free Water Supply is assured

Jain Irrigation Experience

Water shed Management

- Located at Jalgaon on the area of 600 acers

- State of the art training centre for the farmers, officials and policy makers focusing on water, agriculture and renewable energy

- All soil conservation measures, water recharge measures are taken care of.

- The conservation and enhancing the biodiversity in same watershed is possible with minimal efforts

Rain water harvesting structures

Rain water harvesting structures

Polylined Tank:

(micro catchment development):

• Useful for sandy / highly drained/ highly saline soil conditions.

• Does not allows direct seepage.

• Can be used for survival irrigation or irrigating one crop in Rabi season.

Back

Rain water harvesting structures

Earthen Bund:

• Earthen bund are small water and soil harvesting structure constructed at the end of ravine/ gullies.

Back

Rain water harvesting structures

Percolation Tank:

• Percolation tank is an earthen / masonary structure with the purpose of ground water recharge.

• It is usually built on large streams where large catchment area is available.

Back

Artificial recharge and soil moisture improvement measures

Advantages:

• Creates a groundwater ridge or mound around existing groundwater extraction structures.

• Increases discharge rates.

• Improves quality of groundwater.

• Prevents temporal decline of water table in the region.

• Increases annual ground water recharge.

• Creates scope for additional groundwater extraction.

• Maintains a safe groundwater balance.
