Rainwater Harvesting With Rainwater Diverters

A rainwater diverter kit for rainwater harvesting is an ecologically supportive way of collecting water for use in the garden. eBay offers a variety of affordable rainwater diverters suitable for residential use.

Why use a rainwater diverter?

For keen gardeners who like to do their bit for the environment, a rainwater diverter can be an excellent way to collect water that doesn't involve turning on a tap. By diverting the water from gutterings and drainage systems, you will be using water that naturally collected, as well as feeding your foliage with water free from the chemicals traditionally used to clean the water used within your home.

Different types of rainwater diverters

Depending on your needs, there are various diverters available. These include:

  • Downpipe diverter: Usually comprised of downpipes with a release valve at the end of the pipes. The pipes hang down the main pipe flowing to the storage tank from the T-junction so that one flows to the storage tank while the other flows to the downpipe water diverter.
  • In-ground diverters: These diverters are buried underground in a wet rainwater system. The system is fitted at the lowest point of the riser pipe which then feeds the storage tank. Just like downpipe diverters, this system also separates contaminated water from clean water.
  • Wall/post diverters: The difference between this diverter and the downpipe diverter is that it allows for a bigger reservoir because several downpipes can be connected to the reservoir. These diverters can be mounted on a wall or a post.
Does a rainwater diverter cleanse the collected water?

Yes. The first-flush of rainwater is often contaminated with unwanted materials, which can include animal droppings, dust and dry leaves, twigs, and insects. The construction of a rainwater diverter includes a contamination reservoir and a storage tank. The contamination tank strips out the debris, filtering the clean water into the storage tank. In many rainwater diverter models, a small floating ball is part of the functionality, acting as a 'stopper' between the two.

Using a hose with a rainwater diverter kit

If you want to water your grass and flowerbeds, a hose might be required. You can either use the natural water pressure of the storage tank or fit a pump to increase the range and spray of your hose. For larger gardens and for those who need to extend their hose to boost its reach, a pump would be advisable.
