Rain Water Tank

The Eco-friendly way of harvesting water

Rainwater Catchment Tanks are an eco-friendly way of harvesting rainwater which would normally run off your building roof and down your drains. Rainwater costs nothing. As such the system reduces the amount of potable water you would normally use for cleaning purposes.

The harvested water is captured from your roof drains, filtered if necessary and stored in the tank for on-demand uses like general cleaning, flushing toilets, and irrigation. The system typically comes with a pump to direct water via the plumbing to a specific point of use.

Useful Information

Tank Design & Shape

We ensure the tank design is aesthetically pleasing to fit the overall dimensions and look of your building. Some tanks can be an eyesore by size, shape and colour. There are various size tanks available to suite specific requirements.

Underground Installation

Tanks can be also be installed underground as an alternative.

Rainwater Is A Clean Source of Water

A water treatment system is not required if harvested water is only used outdoors or for cleaning. Water must be treated if plumbed for indoor use.

Reduces Water Downtime

The system ensures an alternative water supply in the event of water restrictions or municipal water switch off.

Payback Period

Typically 10 to 15 years but this will reduce as water supply becomes more expensive.

The Science Behind The Water Tanks

It is generally accepted that 1mm of rainfall over 1m2 will give you 1 litre of rainwater.

Additional Filtration For Human Consumption

Harvested water can also be used for human consumption with the correct filtration treatment inside the tank.

Additional Requirements

Water is typically pumped to the point of need by a small pump system which can be fitted with a timer if required.

Implementation For Garden Irrigation

The system can be connected to the garden irrigation scheme.
