Pakistan has remained an agricultural based economy for ages. The sector still has a lot to add in the economy mix. The diversified climate, fertile lands and good canal system make all the scores to keep on improving this sector.

Water pumping is conventionally done through large tube wells, which are operative on WAPDA Electricity or Diesel Gen Sets. These are used to store water in huge compounds and then distribute to the cultivation fields through a network of streams. The activity is termed as flood irrigation and is operative during the seasons.

The system is not only water pumping but it comes with a whole lot of delivery, storage and distribution infrastructure. Tube wells are planned at centralized location and the delivery is connected to nearby lands through streams. Thus the scattered lands, which are not connected to the distribution water streams, remain deprived of irrigation water. Even those connected through the streams are either dependent on WAPDA's electricity or burning precious fuel.

The concept of Solar Water Pumping is that of drip irrigation, which is a much appreciated practice globally. This is because it is not only an efficient irrigation system consuming optimum water quantities, it also requires relatively less delivery and distribution infrastructure. Rather, its basic principle is to have more scattered pumping units at designated places from where, the further distribution is easier. Solar water pumps having the limitation of flow rate fits well in this concept. It is partly offset by the fact that sun is available throughout the year and it even keeps pumping during off season. The water pumped during off seasons can be stored to meet the demand on peak season.

Keeping all above in view, the solar water pumps can be installed and used. The capacity calculation needs to be determined on the basis of annual delivery capacity as sun is available throughout the year to operate the pump. An appropriate storage is to be prepared/utilized, which will keep storing the water during off seasons. This approach will enable to select low delivery pumps, which will deliver less on a daily basis but meet the overall requirement on an annual basis.

It also needs to analyze the distribution requirement. There should be scattered pumping units with a relatively small network of distribution streams with each unit. This will also alive the un-utilized lands, which are waiting for supply of irrigation water from canals or tube wells.

Clean Power has a wide range of US and German products, which are specially designed and configured for solar water pumping application. With the guidelines presented in this paper, the appropriate models can be selected from the catalogue.
