Oasis Underground Water Tanks

OASIS systems are manufactured using fibreglass underground water storage tanks, not plastic, here in the UK

Rainwater Harvesters - The Principle
Rainwater Harvesting is simple. Water from the roof is filtered and stored in the OASIS tank, from where it is pumped on demand to garden taps, washing machines and toilets.

Why Harvest the Rain?

Because rainwater harvesting makes sense. Rainwater can be used for so many domestic and commercial purposes. It is free, clean and harvesting helps to fight the effects of climate change for both drought and flooding.

Benefits of using rain instead of mains water

Rainwater is a free, natural, environmentally friendly resource. Rainwater Harvesting upholds all the ethics of Sustainablity - Reduce, Recyle and Reuse, as used by

It acts as a cushion against future price increases by the Water Companies - future Hose Pipe Bans will not affect you. - Helps to reduce flash flooding - Easy to install.

  • Designed for a simple DIY installation

  • Easy water connections for up to 110mm standard drainage
  • Screw down manhole lid.

Reduced Surface Water Soakaway Area Required

If you install a rainwater harvester then the surface water soakaway area required is reduced dramatically as it is only needed for the tank overflow during periods of heavy rain.

This has big advantages for small gardens.

Less strain on the septic tank soakaway area

As the rainwater soakaway is reduced in size it frees up more space for a septic tank soakaway.

Less energy and chemical use for rain used in the home and business compared to mains water

In the UK, every litre of water uses 280 watts of electricity to purify it. We then waste all this energy by using the water to flush our toilets and water our gardens when we could be water harvesting for free.

Many chemicals are also used in water purification and these are not required for rainwater.

Rain water harvesting saves you money and helps to save the environment
