It is difficult to rely solely on tanks above the ground for massive water needs. Hence, large reservoirs are created on the ground, which can store a lot of water. It is also a better alternative for agricultural needs since it can easily collect water during the monsoon season.

Openwell Submersible Pumps are completely airtight and are placed submerged in the reservoir. In these pumps, water is sucked in through the inlet. As the motor operates, the rotary motion of the impeller moves this water upward and gives it enough energy to reach its destination.
