Water Butts: The Best Options to Help Start Saving Water Today

Water butts are basically large containers that are used to capture and collect rainwater. This is usually done by connecting the water butt to your downpipe, which will lead off your guttering.

Many water butts come complete with diverters, designed to fit on to the end of your downpipe and direct the water into the butt. Some also come fitted with hose fit taps. These not only act as taps from which to dispense your collected water, but can also be fixed to your hose.

A lid, to prevent leaves and debris falling into your water and also to act as a safety measure for those concerned about children, pets or wildlife falling into the water, is also handy.

Why Should I Get a Water Butt?

There are lots of great reasons why you should get yourself a water butt, including:



  • If you are on a water metre and find yourself regularly using your mains supply to water the garden you will see your water bill drop — particularly during the summer months
  • Waterwise states that, if every household in the UK got a standard water butt around 30,000 million litres of water could be saved each summer
  • Plants and wildlife respond better to rainwater than tap water
  • Hosepipe bans will no longer be an issue for you in the summer months as you will have stored plenty of rainwater.

How to Choose the Best Water Butt

When choosing a water butt you should take into account the space you have available for it. It will need to be located so that the downpipe that runs off the guttering of the house or building can easily reach it. Most water butts come with a diverter that fits onto the downpipe and directs water into the butt.

Water butts usually sit close to a wall, so do choose one that won't take up too much space or be in the way of any doors or windows. 

You should consider safety and practicality too. Choose a butt with a lid to prevent children or pets from falling in.

Investing in a stand to raise the water butt off the ground will make connecting a hosepipe or filling a watering can from the tap simple.
