Summer - perfect time to install rainwater harvesting systems

You may think that summer isn't the best time to think about rainwater harvesting, but you'd be wrong. Having started with the humble water butt, there are now systems that sit under your garden that filter the water so it can be used to feed systems in the house.

Therefore, summer is the perfect time to excavate your garden, install a rainwater harvesting system and keep mess to a minimum. It is then ready to collect all the rainwater that will fall during a typical British winter!

What are rainwater harvesting systems?

As the name suggests, rainwater harvesting systems collect rainwater.

Technology has developed quite considerably and whilst there are still water butts that collect rainwater for use in your garden, you can now enjoy systems that are connected to your home's pipework. The collected rainwater will be filtered and can then be used to feed your washing machine and flush your toilet. This means that you will be reducing your water consumption and thus reducing your water bills.

As mentioned above, installing one of these systems will mean excavating your garden as the water tank will sit underground, so it is quite a big job, but it can also be extremely worthwhile.

Alternatively, there are now rainwater harvesting systems that can sit in a loft and collect rainwater straight from the roof of a home. However, due to the location of the tank, it is limited in size so won't collect as much water as an underground system.


Are there different size options?

The simple answer is yes. Before you decide what size to go for, consider the amount of rainfall you generally get and what you want to use your rainwater harvesting system for.

A small system that will generally be used in your garden can typically collect 200 litres of rainwater and the roof systems around 455 litres, whereas an underground rainwater harvesting tank can store in excess of 6,000 litres of clean water.


How do you maintain the systems?

A rainwater harvesting system needs very little specialist care. The majority of the underground systems are self cleaning and only need checking once a year. As the tank is buried underground, it isn't affected by heat and light so the water won't go off.

It's much the same with a system that sits in your loft, however, the water will go stagnant if left not used, which can be an issue when you go on holiday.

Rainwater harvesting and greywater harvesting, what's the different?

Whereas the concept of rainwater harvesting can be understood quite easily just by the name, greywater harvesting generally needs a bit of explaining.

Greywater is wastewater that has already been used in the home for domestic purposes, such as washing clothes, showering and bathing.

A greywater harvesting system will either purify the water or just redistribute it so it can be used again for things such as watering the garden and flushing the toilet.
