Water supply systems usually need high pressures so as to pump water to longer distances. It is also possible for systems that have water moving in a cycle to lose the pressure after some time. In such cases, the system requires a booster pump that will supply the extra pressure. Listed here are the various scenarios that need incorporation of booster pumping mechanisms.
Pumping Water over Long Distances
A working system of water supply makes use of pipes, valves and gates to direct water to a given location. Friction, which is an opposing force to the flow of water, acts on the water in the pipes. Frictional force is usually greatest if the water has a longer distance to cover along the pipes. The implication is that there’s a significant reduction in the pressure of the water. Due to this phenomenon, there’s need to inject in some extra pressure to ensure that the water reaches its intended endpoint. This is accomplished by installing booster pumps at certain points in the system.
Deep Well Water Extraction
Some wells from which water is to drawn have a greater than normal depth. Wells that are sunk in arid and semi-arid areas are usually of this nature. Water from such wells usually need high pressure to overcome the force of gravity and deliver it to the ground service for supply. As such, the system must be equipped with the appropriate booster pumps since a single pump may not be adequate in carrying out the task.
Systems That Have Fluctuating Demands
Municipal water supply systems have to deal with varying demands for water from their clients. In the course of a single day, different people will require various amounts of water for their use. The result is off-peak hours where demand is low and peak hours where demand for water spikes. Peak consumption rate is hardly the parameter to use when setting up a supply system since this would mean losses for the company. The best approach to ensure optimum operation would be to install a system that can comfortably handle off-peak supply, then have a system of booster pumps to take care of the peak hours. Irrespective of the conditions during operation, such a system can handle the varied loads perfectly.
Waste Management and Sewerage Systems
Municipal sewage waste also has varying degrees of viscosity. The higher the viscosity, the higher the pressure required to drive the waste so as to avoid clogging of the system. The system will therefore need to be designed with the normal flow in mind, then a separate booster pump system put on standby for those instances when the flow will be extra thick.
