Role of Rain Tank Pump in Rainwater Harvesting
Collecting rainwater for household chores or commercial objectives is a great idea for using rainwater sustainably. The idea of collecting and using rainwater for human use is called rainwater harvesting.
There is no problem conducting the collected water to different home areas if the water tank is situated on the roof. But if you collect the water at or below ground level, you need a rain tank pump to create water pressure. A water tank pump is a vital component used in rainwater harvesting.
Types of Water Tank Pumps
A variety of water tank pumps are used in rainwater collection and supply systems. These pumps may vary in design, flow rate, power input, and other features.
As two common types, the first rain tank pump type can be a submersible pump, which is submerged in the water tank to supply water to the areas where it is needed.
The second alternative is a surface pump, which sucks water from the water surface. This type of water tank pump is suitable for shorter distances.
A rainwater harvesting system in a large building may use both types, where a submersible pump supplies water to an intermediate water source, and a surface pump then pumps the water again to the final destinations.
Performance Factors
Many pumps with many features are available in the market. A house owner will choose a rain tank pump based on pre-defined factors.
These factors include:
- The distance between the water sources and destinations
- The total number of water outlets
- The size of the pipe
- The difference in altitude between the water tank pump and the highest outlet
Your pump will function better if you consider all these factors before arranging a water pumping system for rainwater harvesting.
Required Components for a Water Tank Pump
A power controller unit is a must for most rainwater tank pumps. A simple switch can do this job, or you can buy a feature-rich device with advanced systems.
Another required component of a water pump is a non-return valve. This valve prevents water from flowing back to the water source. It is primarily an automatic system that cuts the power supply when the water level is too low in the water tank. Efficient water pumps protect your tank from running out completely.
As you can see, the role of water tank pumps is crucial in a rainwater system. You must buy water pumps from reliable sources after considering all the required factors.
