Below Ground Commercial and Agricultural

A below ground rainwater harvesting tank does not take up valuable storage space at surface level. It is often the only place to install one in order to pick up existing underground drainage. Once the roof water has collected in the tank it is then pumped back to wherever it is needed. This is looked after by way of a control panel, pressure switches and floats. The tank will also have a gravity outlet drain should the rainfall exceed demand for water at certain times of the year.

Commercial and agricultural uses would be:

• Vehicle wash plants
• Crop spraying water storage
• Crop irrigation
• Dairy wash down

The main components of a large below ground harvester tank are shown below.

Above Ground Commercial and Agricultural

When you need a retrofittable large scale rainwater storage solution, the above ground Commercial RainStore rainwater storage range is the best option available on the market.

The range features capacities from 1300 to 10000 litres, sizes that will really make a difference to metered properties and areas prone to water restrictions in summer months. The tanks are rotationally moulded, tough, durable and built to last. These UV protected tanks feature on the Qualified Technology List (UK). The range has also been awarded the Waterwise Marque of Excellence (UK) which raises the awareness of water efficiency and reducing water wastage.

Typical uses include:

• WC and urinal flushing
• Vehicle washing
• Irrigation and landscape gardening
• Plate cooling
• Plant washing
• Washing down parlour

How It Works

The above ground Commercial RainStore tanks can easily be fitted to existing guttering of a building or incorporated in new build plans.

They collect rainwater from the roof via the downpipe. The rainwater flows though a filter to remove unwanted debris and then flows straight into the tank. There is an option for in-line and submersible pumps for the extraction of water.

Rainwater inlet from roof

	Filter unit to remove dirt and debris from water before it flows into the tank (optional extra)
	Dirty water removed by filter washes back into the drain 3.
	Calmed inlet at bottom of the tank so incoming water does not disturb any settled sediment (optional extra)
	Siphon overflow located at the tank fill level skims off excess water and floating debris and returns to drain
	2 bsp outlet for connecting to inline pump or for linking to additional tank
	Inline pump for extraction of water to required application. Tank fittings for a submersible pump are standard on all tanks (not included)
	16 lid for inspection and maintenance purposes
	Watchman to monitor tank water level (optional extra)

When you order a tank from the Commercial RainStore range the following will be included:

• Calmed inlet
• Overflow siphon
• 16 lid
