ALTERNATIVE ENERGY BASED

WATER SOLUTION MODEL

(WSM)

Concept WATER SUSTAINABILITY- CRISIS TO SOLUTION

• The Crisis is Looming over Pakistan and is expected to create many civil issues. Instead of 45 gallons (standard of WHO) Karachi citizens are getting only 25 gallons/day.

• The total being received for various utilities in Karachi for consumption is again200 million gallons less. It is therefore our responsibility to create awareness and process solutions for Water Crisis.

Concept WATER SUSTAINABILITY- CRISIS TO SOLUTION

• WATER SUSTAINABILITY – – River water will not be able to meet future

demands– Changing weather patterns may also change

water from rivers– Global and local warming is anticipated to

reduce the snow accumulation in mountains thereby affecting river water adversely

– Sustained water source is only sea

Concept WATER SUSTAINABILITY- CRISIS TO SOLUTION

• CRISIS TO SOLUTION– Provision of Fresh water– Sea water is the natural solution for lower Sindh and

Balochistan’s coastal belt– Energy cost that comprise 80%-85% of operating

cost can be reduced by using wind and other alternative means

– Use of gravity to supplement Reverse Osmosis pressure will further reduce energy requirements

• Wind lean period can be alleviated by extra additional storage

• Wind turbine once locally made will reduce the cost as well as provide additional jobs

CONCLUSION

Similar Water pumping example in Karachi, Pakistan

Concept is not theoretical as already similar examples exists in Karachi as follows

100-110 MGD Hub Dam Water ChannelArriving at Hub Water Pumping Station on

Shahrah-e-Madinat AlHikmah

HUB PUMPING STATION

• AVERAGE WATER PUMPED= 110 TO 115 MILLION GALLONS / DAY (MGD)

• HEIGHT OF STORAGE TANK= 182 FEET

• SIZE OF PIPE= 66 INCHES

• PUMPED IN TWO SETS WITH 5.8 MW AND 6.8 MW POWER
