SOLAR DUAL PUMPWATER SUPPLY SCHEME
Dr Praveen Gedam, IASDirector,
Groundwater Surveys & Development Agency,Pune, Maharashtra.
Present Scenario
• Small habitations (up to750 population) need smallschemes.
• Bigger piped water supplyscheme is not possible.– Initial high per capita cost.– High operations &
maintenance cost.– Electricity bills, etc.– No electricity (power cuts)-
scheme doesn’t work.

Present Scenario
Traditional schemewith reservoir.
98000.00
91000.00
Huge electricity bills
Present Scenario
• Hand pumps have limitations.– Can’t draw water from below 120 feet.
• Agencies (govt & private), don’t usuallyventure to go to naxal affected, tribal andhilly areas.
Present Scenario
• Hand pumps, wells,river situated atdistance– Problem of fetching
water manually– Wasting of precious
time & energy– Always women do all
the hard work– Non-potable water,
especially from rivers,lakes

Method of Dual Pump Installation
• Dual pump System can be installed on a Bore well/Tube well having yield, not less than 2000 liters perhour and water should be potable.
•There should be open space free from the shadow ofany house or tree, near the Bore well, to install Solarphotovoltaic panels.
•First of all remove the existing hand pump from theBore well.

Method of Dual Pump Installation
Special water chamber, innovated by GSDA is mountedon the pedestal of hand pump.
Solar energy based Submersible pump is lowered andit’s Riser pipe which is a HDPE pipe of 25 mm dia is fixedon the nipple of this special water chamber.
Dual Pumping arrangement in a single Bore well/Tubewell is possible due to this special water chamber.
It also facilitates removal of Hand pump cylinderand riser pipes, without removing Submersible pump.
It also provide opening into the bore well for Roof toprainwater harvesting.

Prefabricated structure
Facilitation Centers for VWSCs.
Readymade Pre –Fabricated Steel Structures and Pre–Cast RCC Blocks.
Village Water Supply and Sanitation Committees can procure from thesecenters.
Specially designed anti theft nut bolts are used for Solar panels.• Bolt head is made like Rivet.• Nut is attached to another rivet head.• After tightening to required torque nut gets separated from the rivet
head.• Hence spanner can not be useful to remove the panels.

Konkandara- Daregaon a Tribal Habitation in Nashik District.
GSDA has completed1860+1= 1861 schemes in far
flung areas ofMaharashtra…… leading to
elimination of misery for about8.96 lakh people
Jalalpur – a Tribal and Hilly Habitation inAmravati District
A Hilly forest habitation Chavni, Raigad District –in Sahyadri Hill range
Adle -- a Remote Hilly habitation in Pune District.Source of drinking water - Hand pump, away from the habitation.power supply - Interrupted.Hand pump - become non functional due to depletion of water level during summer.
Now no problemSustainable water supply throughout the year without energy charges.
Use of existing structures also ..
Visit ofShri Navinkumar,Secretary ,MDWS,
andShri T.M.Vijay Bhaskar,Joint Secretary, MDWS
to Solar based Dual pump Water Supply Scheme
Name of habitation- Aadle.Dist. Pune.
Hon’ble Shri Jairam Ramesh, Union Minister, Rural Development ,proposed Solar Based Dual Pump Scheme as a Key Solution for smallhabitations in IAP Districts in the Workshop chaired byHon’ble Shri Manmohan Singh, Prime Minister,on 13 th Sept 2011 - Vigyan Bhavan, Delhi.
Govt of India decided to upscale the programme tothe whole country.
"I strongly believe that Solar Dual PumpScheme is a very appropriate model forIAP (Integrated Action Plan) and otherdistricts to provide piped water supply tosmall and remote habitations".
• Naxal affected 9 states taken in the first stage.• Plan to take it up in more than 10 thousand habitations in
the country.• It can be upscaled in non-naxal affected states also.• GSDA, though state govt agency, has been appointed as
nodal agency for the whole country

We are going ahead
• Engineers and officers of AP, UP, Jharkhand, MP,etc have seen the scheme and are in process oftaking this up in a big way in their states.
• Scheme is also well suited to other institutionslike tourist bungalows, hotels, military camps infar off places, hospitals, etc.
• Pune railway station has requested GSDA toconstruct a scheme in their premises forpassengers.

Involvement of local community
• Village water supply and sanitation committee (VWSC)formed in each village. Only villagers are members, oneof them being chairman and one secretary. (SometimesGramsevak is also secretary).
• All the funds with the GSDA are given to VWSC. (Not tocontractors).
• It is VWSC which does financial dealings includingpurchase of raw material and dealings withcontractors. Total financial transactions so far Rs 91.39crore
• GSDA does handholding.

Involvement of local community
• VWSC submits periodical reports toGramsabha.
• After completion, scheme is handed over toGram Panchayat for maintenance.
• This system involves villagers from theinception of the scheme and thus develops asense of ownership among them (AamchiYojana!). Makes the scheme sustainable inlonger run.

Results
• Providing water to– 1793 habitations– 8.96 population
• Scheme in progress in another 2000habitations with population of about 1 million
• So far, misery of almost 1.9 million peopleeliminated or being eliminated.

Effect
• Savings– Electricity bills per year
Rs 6,000 per scheme per year.• Coal need NOT to be burnt for producing this
much electricity– 0.6 to 1.2 metric tonnes per scheme per year– That is about 15-30 tonnes of coal for 25 years for
only one scheme• Due to one scheme, 30-37.5 tonnes greenhouse
gases NOT produced in one year.

Total impact on environment
• For 1793 schemes– Saving of Rs 1.07 crore on electricity bills per year.– Saving of 21.51 MT of coal per year.– 2689 MT of less greenhouse gases in a year.
• So, in 25 years, this converts to– Saving of Rs 26.75 crore (not adjusted for
inflation).– Saving of 537.75 MT of coal.– 67237.5 MT less greenhouse gases.

Total impact on environment
• These figures are for 1793 schemes.• 2000 more scheme are in progress this year.• And Govt of India intends to take such
schemes in about 10,000 habitations.• Just imagine comparable savings and effect on
environment for these figures.• If 10 thousand schemes are completed,
electricity saved can be used for lighting up3.37 lakh rural households!

•Quality and yield testing of Bore well /Tube well.
Check the quality of water of this Bore well /Tube well.If the water is potable then confirm the yield.Yield should be confirmed with the help of yield testing unit.Yield testing unit should be provided with single phase 1 HP submersible pump along withDiesel Generating Set to avoid dependency on electricity supply.
•Yield Testing.
Yield testing should be carried out with the help of 1 HP single phase submersible pumpwhich should be installed at the depth of 57 m in case of 60 m deep BW/TW.
Proper care has to be taken. Yield test should be carried out under the supervision of JuniorEngineer in the presence of Village Panchayat Chief.

Solar Panels
•It should not be far away from Bore well /Tube well to avoid current losses.•It should not be located under the Tree.•It should have space for fencing for protection.•It should have proper foundation as the steel structure of solar panel has to withstandagainst the wind of 200 Km/hr velocities. Hence don’t locate it on exposed rocks.
Storage tank
•It should not be far away from Source to minimize rising main.•It Should be located to give proper distribution by gravity to cover entire habitation.•It should have proper foundation within 2 m depth.
Distribution system• House to house connections should be provided.
