How To Set Up Rainwater Harvesting

A rainwater harvesting kit involves three primary areas of equipment:

  • A tank
  • A pump
  • Filters

Let's have a look at these key components of rainwater harvesting systems in more detail so you can feel confident about your set-up and ready to harvest.


When you're looking for a rainwater harvesting tank system, you'll want a tank that suits your home or business size. One of the main issues when embarking on rainwater harvesting is underestimating the size of tank you'll need, so it's always best to discuss your requirements with your rainwater tank supplier directly. Note that water tanks used commercially are typically 100,000 litres of storage upwards.

As a quick checklist, you'll be able to recognise a good tank - installed above or below ground - as it will have the following features as standard:

- An overflow trap or unit
- Calmed inlet
- Pre-tank filters


When looking at rainwater filters, be aware that there are several types available depending on your requirements, including in-tank, pre-tank and downpipe filter. If you're looking to use your rainwater harvest as drinking water, you'll want a UV unit, fine sediment filter and even self-cleaning tech as part of the filter unit.

A good rainwater harvesting kit's filter should ideally be non-blocking - in other words, not requiring a first flush diverter. These diverters are used to discard a downpour's first portion, an unnecessary component if you have a quality non-blocking filter in place.


As one of the components of rainwater harvesting systems, a pump is especially pertinent if you require your rainwater in your building, such as to flush toilets. For rainwater harvesting tanks situated below ground, this will be a necessity in order to supply the water, and to a reliable pressure.
