Rain Water Tank Pumps

Teknik Group specialises in rainwater tank pumps for built up city areas where noise is often an issue.

A rainwater tank pump is a device used to extract and distribute water stored in a rainwater harvesting tank. These pumps are commonly used in homes, farms, or businesses to collect rainwater, store it in tanks, and then pump it out for use in irrigation, cleaning, or even as potable water (with proper filtration and treatment).

There are different types of rainwater tank pumps, typically designed based on how the water will be used, and the size of the system:

  1. Submersible Pumps: These are placed inside the rainwater tank. They are good for deeper tanks and are quieter than other types because they operate submerged in the water. They are typically used for domestic or agricultural irrigation systems.
  2. Surface Pumps: These are installed outside the tank and are connected by a pipe to draw water. They are typically used when the tank is above ground, or the tank needs to be positioned a little further from where the water is being used.
  3. Pressure Pumps: These pumps are often used when water needs to be delivered under pressure, such as for indoor use (e.g., for flushing toilets, showers, or even for drinking water systems). Pressure pumps can provide higher flow rates and maintain consistent pressure in a plumbing system.
  4. Solar Pumps: Some systems use solar-powered pumps for eco-friendly rainwater harvesting. These are ideal for remote areas or for users who want to reduce their carbon footprint

The pump is an essential part of a rainwater harvesting system because it ensures that water stored in the tank is efficiently used when needed, especially in places where municipal water supplies might be inconsistent or unavailable.

Often there rainwater tank systems use a “Change over switch” To automatically switch to mains/town water in the event the tank water runs out.

There are several brands that manufacture rainwater to mains water changeover systems, which automatically switch between using rainwater and mains water depending on availability. Here are some popular ones:
