Harvesting Water Pump in a Rain Barrel

The Use Of Rainwater Harvesting Water Pump In a Rain Barrel




 rainwater harvesting system


A water pump refers to a device designed to pump liquid under high pressure.The use of a water pump, depends largely on what the rainwater will be used for. Without such equipment today can not do without any private household. With the help of this unit, water is supplied from wells or wells, ensures the smooth operation of the water supply system, irrigates the garden plot, fills the tanks

If a 55-gallon rainwater barrel is placed on an elevated site, it may not need a pump if its only purpose is to water outdoor plants and other light garden needs. The force of gravity created by an elevated rain barrel should provide enough pressure to allow water to flow out of the spigot and through the hose.

A large water tank designed for heavy rains and designed to meet the basic water needs of the home, such as laundry and cleaning, may not provide sufficient water pressure by gravity alone. In this case, a water pump will be needed to increase the water head.

Household pumps come in surface pumps and submersible pumps. For domestic use, the first type is more often used. Surface pumps are used for autonomous water supply of private houses, irrigation of adjacent territory, pumping water from basements and ponds, pressure boosting for autonomous water supply to a private home.

When installing a water pump we use it for the following purposes:


Indoor plumbing – bathrooms, kitchen, laundry.


Lawn care

Car care – washing, residential RV maintenance

Before installing a rainwater pump, you should also consider the amount of rainfall. But first you need to make sure that the amount of rainfall in that particular region is sufficient to meet those needs.

Variety of pumps by design:

By design, all pumps differ from each other. They can be vertical and horizontal. All pumps differ in their assembly, depending on the model, they may have blades, vanes, and propellers.

Area of use:

Domestic – designed for:

  •  creating pressure in autonomous heating systems in private homes;
  • Water supply in the absence of centralized sources of supply;
  • pumping wastewater in sewage systems if it is impossible to provide the necessary gradients in the pipeline
  • We will consider the two most common types of water pumps for rainwater systems.


Jet pumpsJet pumps

The vortex type of pump is the most commonly used due to the ease of installation. In domestic needs, such a unit is installed in country houses to provide water supply. The circulation of water is provided by the liquid, which is fed to the blades located in the pump housing. The key element here is the wheel, to which the water is fed through the inlet. This pump is also used for wells, as they create high pressure. They are self-priming and can handle not only liquids but also gas and water mixtures.This suction is created by an electric motor that drives the rotating impellers. The rotation of these impellers creates a powerful vacuum that draws water through itself.

For domestic purposes, pumps are used for construction, pumping water from wells and wells, for drilling a well, and for heat supply. Drilling a well requires the use of a pump station or a submersible pump. The pump provides water from the well under low pressure. The main advantage of a jet pump is that it is easy to maintain. It is also cheaper than a submersible pump.


Submersible pumpsSubmersible pumps

Submersible pumps are used when working at a depth of more than eight meters. All types of submersible pumps have a cooling system, and are also made of a strong material that helps avoid deformation under pressure. Submersible pumps can be centrifugal and vibratory. The internal components of a submersible pump consist of a series of impellers that rotate to create a vortex motion, pushing the water up and through the plumbing. In the second type of pump, the liquid is drawn in by a vibrating or electromagnetic mechanism.

The advantage of the submersible pump is the silent operation of the pump motor and it does not take up much space.

One of the biggest disadvantages of submersible pumps is their high cost compared to an external pump.

What pump to choose? The choice of buyers:

Advantages of outdoor pumps:

  • effortlessly pumps water to a height of 15 to 20 meters;
  • the pump is easy to service;
  • easy to install.

Disadvantages of external pumps:

  • with its help it is impossible to pump water from a depth of more than 7-8 meters;
  • the electric motor is very noisy, of course, there is an option to purchase a silent pump, but its price will be many times higher.

The advantages of submersible pumps:

  • with extraordinary ease, such a pump is able to lift water from great depths, will cope even with a depth of 40-50 meters;
  • noiseless operation of the pump motor;
  • does not take up much space;
  • The service life of submersible pumps is up to 15 years.

Disadvantages of submersible pumps:

  • Its high cost compared to the outdoor.

In any case, you should consider the amount of rainfall in your area, where rainwater is the main source of water for the house (and where there is enough rainfall), a submersible pump may be more appropriate. Since you will need a rainwater tank that is large enough and the pump will be used much more intensively, it is worth using a submersible pump that pumps water from the tank.
