Rainwater Harvesting Systems
The rainwater harvesting systems and packages on this page contain everything you will need if you wish to install a rainwater harvesting system, including water butt, diverter, filter and pump. If you would prefer to buy each of these components separately, visit the corresponding pages in this section. For those new to the field, it may be easier to buy a package which includes all you need rather than having to decide on each component individually.
The types of system can be broadly categorised as below:
- Underground pumped rainwater harvesting systems - these are the gold standard for rainwater harvesting systems. Being below ground the system is out of the way and stored water remains is unaffected by ambient temperatures.
- Above ground pumped rainwater harvesting systems - these are ideal when space for an underground system is not available
- Above ground gravity rainwater harvesting systems - these systems are a low cost solutions with no electrical input. Stored water is discharge by gravity alone.
Here is a brief description of each of these components so that you know what is included in our rainwater harvesting packages. Details of each individual kit are in the individual product pages listed below these descriptions, and links to the individual pages are in the headings.
In most rainwater harvesting systems water flows from the roof down a downpipe (drainpipe) to the water butt, where it is stored. Diverters are the pipes used to connect the downpipe to the water butt. The most basic are used for this purpose only, whilst others also filter the water they divert.
Filtration is an integral part of rainwater harvesting systems. Filters typically remove contaminants such as dust, leaves, organic waste. Even if the water isn’t being used for drinking it is useful to remove these contaminants. In some systems a filter is placed in the diverter, whilst in others it’s in the downpipe or in the water butt.
However the rainwater you collect is being used, one or more pumps are usually required to move the water from the water butt to where it is needed. Pumps placed inside the water butt are termed ‘submersible pumps’, whilst those placed outside are termed ‘non-submersible’ or ‘above ground pumps’.
