Due to excessive digging of new tube-wells and incessant use of existing ones, ground-water levels have depleted severely rendering many a tube-well dry. With these tube-wells being the primary source of water for farmers during non-rainy seasons (around 9-10 months a year), their agricultural output falls drastically with the going dry of the tube-wells. Having to pay exorbitant prices for water from other suppliers, decrease in crop diversity (sticking to drier crops) and limited crop cycle(s) are just a few of the challenges that arise from a dry tube-well. The result is an adverse impact on the farmers' livelihoods and ultimately on the agricultural sector in the country.

The Solution: What is your solution? Be specific!

Direct tube-well recharge technique has been perfected by SRDS. Its salient features are:

1.Quantity increase: Implementation of the technique shows a 3-6 times increase in the tube-well's water-output. Completely dry tube-wells too have been revived.

2. Quality improvement: Sending back of natural rain-water underground makes the tube-well's water-output lose its hardness.

4. Cost-effective: Use of only natural materials helps keep the cost much lower (Rs 30,000/-) compared to the cost of getting a new tube-well (Rs 1,50,000/-) which is the nearest alternative.

5. Permanent: It is a permanent solution to water-scarcity issues faced by farmers.

6. Flexible: Can be customized to meet the needs of all.

Recharged tube-wells meet the agricultural water-requirements of farmers. Thus, increased no. of crop cycles, crop diversification and higher yield lead to exponential improvement of their livelihoods. Also, eco-friendly water conservation improves ground water levels.

The Model: Walk us through a specific example of how your solution makes a difference; include the primary activities involved in your solution.

The stages in implementation of SRDS's direct bore-well recharge technique are:

1. Excavation of the primary percolation pit: A pit sized 10x10x10 in most cases is excavated around the tube-well.

2. Stone-pitching: The insides of the primary percolation pit are stone-pitched for increased sturdiness.

3. Slits in the casing pipes: Tiny slits are made in the casing pipe using a cutting machine.

4. Wrapping of wire and mesh: Wire and mesh are wrapped around the casing pipe.

5. Cement rings: Cement rings (7-8) are laid one upon another around the casing pipe thus forming a circular structure around it.

6. Packing of the primary percolation pit: The remaining area in the primary percolation pit is packed with stones, sand and jelly.

7. Excavation of a catchment area: Ponds / trenches / soak pits are excavated as catchment areas and connected to the primary percolation pit by way of underground pipes / underground canals / smaller trenches.

8. Water seepage: The water harvested in the catchment areas seeps into the primary percolation pit and after natural filtration via the stones, sand and jelly gets to the center where it again seeps in through the gaps between the cement rings.

9. Water percolation: The filtered water once inside the cement rings, goes back underground via the slits in the casing pipe after another round of filtration by the mesh.

10. Tube-well recharged: Thus naturally filtered rain-water is sent back into underground aquifers and water-tables. This increases ground-water levels and ultimately recharges the tube-well.

The Marketplace: Who are your peers and competitors? Identify others working to address the same needs as you and indicate what sets you apart from them.

Competitor 1: Only one other organisation practicing a variant of the technique.

1. Area of practice: While they practice in urban areas on a commercial basis, we deliver our services mainly to farmers in rural areas.

2. Materials and cost: While they make use of unnatural materials to implement recharge structures, we make use of only natural materials to make our services more affordable (half as compared to them) to the rural population.

Apart from, that one peer, the nearest alternative to our service is getting a new bore-well that may not yield any water at all with the depleted ground-water levels. Also, a new tube-well costs Rs 1,50,000/- as opposed to out technique which costs Rs 30,000/- and gives a guaranteed water-solution. Our technique is also more eco-friendly.

Founding Story: We want to hear about your "Aha!" moment. Share the story of where and when the founder(s) saw this solution's potential to change the world.

Kamplikoppa, a tiny village in Dharwad district is where the direct tube-well recharge pilot project was initiated. 8 tube-wells of willing farmers were chosen for the project. Among the first few was the 20 year old tube-well of Basappa Mulgundmat. Hacing seen his tube-well go completely dry in the year 2003-2004, Basappa Mulgundmat had given away his tube-well machine deeming it useless. On implementation of the tube-well recharge technique in 2009 by SRDS, the amazing water-output from the tube-well during the test run prompted Basappa to get back his machine and have it installed again. Today, the preciously 'dry' tube-well irrigates 6 acres of land for Basappa. Basappa's story, like many others in the village of Kamplikoppa reaffirmed Sikandar's already strong belief in the technique and its potential impact.

Please describe the goal of your initiative; outline what you are trying to achieve

SRDS has a very clear goal - enough water for all farmers in Karnataka by 2020. Owing to the high replicability of the technique, SRDS believes this is well within reach. Once convinced of the technique and its merits, SRDS foresees a day when every farmer implements the recharge structure by himself on his tube-well. We believe word of mouth is the fastest means by which awareness about this technique shall spread especially in rural India. Thus, SRDS believes that by 2020, every tube-well in Karnataka shall be recharged either by SRDS or by the beneficiaries themselves. The technique can also be scaled up to different parts of the country or even the world, such is its potential and replicability.

What has been the impact of your solution to date?

SRDS has reached out to 101 tube-wells with the following impact:

1. Quantity increase: The tube-wells recharged have shown an increase in water-output from 3 to 6 times. In some cases, dry tube-wells are working again.

2. Quality improvement: Sending of naturally filtered water back underground, results in decrease in the proportion of impurities in the underground water. This results in the tube-wells water losing its 'hardness'.

3. Crop cycle increase: Farmers use the recharged tube-wells to irrigate their fields even in the summer thus increasing the no. of crop cycles for them.

4. Crop diversification: In case of water-scarcity, most farmers are compelled to grow crops requiring less water. Water-availability means they are free to diversify.

5. Livelihoods impact: Higher agricultural yield improves farmers' livelihoods.

6. Conservation: The technique has resulted in immeasurably large quantities of water harvested in water-tables for use by future generations.

What is your projected impact over the next five years?

Over the next five years, we believe it is within our reach to spread our technique to at least 3000 tube-wells. With the recently increased acceptance to our technique, we believe implementation of our technique is the need of the hour and sooner or later, everyone shall realise this. Underground water tables are depleting day by day and sending water back down there to recharge them is the only solution. With the recent upswing in requests for our services, we see our demand trajectory setting a steeper upward slope over the next five years. With 3000 tube-wells recharged and healthy underground water levels, the agricultural productivity of the region should also see exponential growth along with a rise in the income of the direct beneficiaries.

What barriers might hinder the success of your project? How do you plan to overcome them?

So far, our biggest challenges have been to gain funding for our projects and to convince farmers to let us implement a new technique on their precious tube-wells. The latter however has been on a decline for a while and we now see increased acceptance for our technique. The financial issue remains our biggest challenge although, with our recent successes,we have seen a rising demand from beneficiaries who are willing to invest the entire cost of the recharge structure by themselves without availing of any subsidy from our side. We expect to see more of such demand because farmers will pay for water, if nothing else.

Tell us about your partnerships

For the sake of revenue generation, SRDS has partnered with Aquasafi Purification Systems Pvt. Ltd. Aquasafi is engaged in providing pure drinking water at affordable prices in rural India. SRDS takes care of the maintenance of the water-purifying units on a contractual basis. This provides SRDS with a steady albeit meagre revenue to meet administration expenses.

Are you currently targeting other specific populations, locations, or markets for your solution? If so, where and why?

Yes, we are planning to scale up our technique to industries, educational institutes and other organisations large enough to have a tube-well to meet their water-requirements and charge them consultancy fees in addition to the project cost. This will enable us to generate revenue to cross-subsidize our services for other beneficiaries who are not as financially well-off.

What type of operating environment and internal organizational factors make your innovation successful?

Operating environment:
An environment in which people are receptive to new ideas and possess the willingness to give them a chance is conducive to our success.

Internal Organizational factors:
A committed team that is solution-oriented is one of the keys to our success. The roles for our internal team are not very clearly defined thus helping us retain flexibility. Everybody puts in an extra shift when required is more than willing to work on the field which forms the bulk of our requirement.
