Water and clean water at that is an irreplaceable resource of our day to day living. Depending on location and accessibility, there are numerous challenges encountered in delivering it to the point of use. In rural areas and most arid and semi arid areas, boreholes and wells are an important source of water. The average depth of a well is around 30m while that of a borehole is about 150m.
There are many traditional/conventional methods of getting water from wells with the most popular being a bucket tied to the end of a rope and a pulley mechanism at the top of the well to lower and raise the bucket. This method although effective is limited in terms of productivity the major reason being slow pace of work. To effectively harness water from a well, modern methods that involve using submersible pumps are available. For areas with access to the electricity grid, these pumps can be connected to the same. However, if there is no possibility to use grid power alternative sources such as solar, wind or a combination of both (hybrid) can be employed. Additionally, if the recurrent expenditure of running such a pump from grid power cannot be sustained, the best option would be to use renewable energy sources. These energy sources require no maintenance and with the right infrastructure will ensure water availability on demand.
Boreholes offer better prospects of higher water yields compared to wells. They have become increasingly popular as a solution for water needs in equal measure in urban, peri-urban as well as rural areas. It is possible to get in excess of 10m3 of water on a daily basis. This level of production makes commercial activities such as irrigation, metered distribution among others viable. As with well pumps, it is possible to use either grid or renewable energy power to operate the submersible pumps used. However, due to the extra depth achieved in boreholes considerably more power is needed. If renewable energy sources especially solar panels are used, a tracking system can be incorporated to increase power availability throughout the day. This will consequently increase water production by 15-20%.
In both cases, i.e. boreholes and wells the ideal thing is to have a reservoir into which water is stored. This ensures availability of water at night or when there is no wind or solar power production to run the pump.
We have a reliable range of submersible pumps and accessories from leading manufacturers in the world to suit either of the two categories.
