FAQ's

+
What is Rainwater Harvesting?
Rainwater harvesting is the collection and storage of rainwater that would otherwise flow down gutters into the drain. Rainwater is collected from the roof, filtered, stored in a tank and then re-used within the home and garden. This can provide substantial savings on water bills, as well as making your home more sustainable.
+
What can you use rainwater for?
Rainwater can be used for all outdoor uses. Watering the garden, washing cars, cleaning patios, drives and windows, topping up swimming pools, ornamental ponds and hot tubs.

With some plumbing alterations, it can also be used inside the house to flush toilets and feed washing machines. Besides saving on potable mains water, rainwater use encourages less build-up of calcium deposits in appliances.

The diversion of rainwater to the storage tank can in many situations reduce the risk of flooding.

The principle uses for rainwater are:

  • Toilets (around 35% water use)
  • Washing Machines (around 15% water use)
  • Garden/Outside Use (around 5%, yet this figure can grow greatly for keen gardeners)

+
Will Rainwater Harvesting Help With My Planning Application?
Yes! The updated National Standards for Sustainable Drainage (SuDS) which was issued in July 25 gives Rainwater Harvesting ‘Priority 1’ when it comes to the preferred methods to control the discharge of rainwater from your development.

You can learn more by Clicking Here to read about the updated standards.

+
How will rainwater harvesting help me during a hosepipe ban?
In recent times many areas have had hosepipe bans, banning the use of hosepipes for watering gardens and cleaning cars.

New legislation will give water boards the right to prohibit using hosepipes for other outdoor cleaning purposes such as washing boats, patios, drives, windows, and also for filling swimming pools, ornamental ponds and hot tubs.

Installing either a Garden System or The Rain Director Gravity Feed System means that you can use the water in your underground tank. This is your water that you have collected and cannot be claimed by the Water Authorities.
