Why not go underground with our well designed, sturdy reservoir which comes fully equipped with everything the gardener needs.
Or for smaller gardens where space is limited and the rainwater requirement is lower.
DIY shops and garden centres have been supplying 100-200 litre water butts for filling watering cans with often unfiltered rainwater. These smaller butts can run dry in conditions recently seen in southern England and many gardeners have taken to linking several butts together to maximise the rainfall harvest.
This approach is not only space consuming, but can also look fairly ugly (especially in a usually well tended garden).
By using a space saving and well designed raintec 3P wall tank, gardeners can store up to 750 litres of filtered (using our designer filter collector) rainwater.
Available in Green,Black, Sand or Grey Granite effect, the raintec 3P wall tank is a durable and premium quality product. Each tank is fitted with brass connectors for both tap and interconnectors.
The addition of a compact electric pump will also allow the use of a hosepipe, sprinkler or irrigation system.
The footprint of the raintec 3P wall tank is 800mm (31.5in) wide x 600mm (24in) deep and is 1790mm (71in) high.

If you wish to add that certain something to your garden.....
Raintec offer a wide range of stand alone or linkable tanks that can fit into your garden design or be discretely positioned to suit. Even on the garage roof!!

Designed and manufactured to the highest European standard. Each filter can remove Leaves, moss, grit etc. from collected rainwater. Thus avoiding a build up of silt in the collection tank and prolonging the life of the system pump.
If you are considering using rainwater in domestic situations for washing etc. especially where water may be heated, we can offer a limited range of Ultra Violet & Ceramic filters to reduce or illiminate bacterial contamination.
Raintec can pass on technical queries to our suppliers but do not accept responsibilty for inappropriate use or installation of this equipment.

For control of rainwater and mains back up when sytems are integrated for domestic use.
From the basic 3P unit to the more sophisticated PowerRain Models, we can supply a system to suit your purpose.

With purity of around 4 parts per million, rainwater is ideal for pole based window technology.
Many window cleaning companies now use water fed pole technology. These systems require ultra clean water wich is achieved using specialist filter equipment.
The process unfortunately means using 100% more water than is required to fill a wfp storage tank due to waste run off.
Using rainwater which has been collected, filtered for leaves/moss etc and has stood for a day or two elimintes the waste run off issue almost entirely.
As the water collected is unbelievably clean, the wfp system filters have to work less hard and thus have a longer life.
Storage from 750 litres upwards either above or below ground.

Why not give your horse, alpaca, goat, etc... a chance to drink fresh natural rainwater from one of our bespoke harvesting systems.
The roof of your animal's shelter can catch hundreds if not thousands of litres of rain. Once filtered using our well designed equipment and stored in a hygenic tank, the water can automatically fill a trough of a suitable size.
No chlorine, flourine or other tap water chemicals, just clean natural rainwater.
Raintec are pleased to be able to advise on and supply rainwater systems for all of your animal watering needs. Please e-mail us with your requirements for a fully bespoke service.
