This 2600 litre underground water tank is manufactured in the UK from virgin Polyethylene and is used mainly for storing harvested rainwater, however it can also be used for storing water from other sources such as springs and wells.

The ribbed design provides added strength and allows for environmentally friendly pea-gravel backfills, eliminating the need for concrete bases and backfills to be used in most installations.

The tank has been designed to ensure optimal strength and is shorter in height compared to other tanks on the market today. This means that a shallower hole is needed to accommodate the tank (this can be as much as 500mm less).

The tank features a large 600mm access which allows for inspection and maintenance of the tank and its contents.

Telescopic Neck & Lid/Fitted Tanks

As standard the tank is supplied as a plain tank with no accessories or fittings, however you can choose to add a telescopic neck and lid, or add a telescopic neck and lid with a pre-installed filter (fitted tank).

The telescopic neck and lid push fits into the neck of the tank and a rubber seal towards the bottom ensures a tight fit. The telescopic part of the neck can be extended by up to 300mm and can be tilted in any direction by up to 5 degrees.

The fitted tank includes a telescopic neck and lid and a pre-installed filter installed in to the neck of the tank, with DN100 rubber seals drilled in to the flat areas in the middle of the neck section. It is also supplied with a calmed inlet and drainage connections.

The compact filter is suitable for approximately 150M² of roof area.

Pump Kit

The optional DAB Divertron 1000 or DAB Divertron 1200 submersible pump kit includes everything you need to pump stored rainwater from your tank. 

The kit includes:

  • DAB 1000 Submersible pump with float switch assembly
  • Stainless steel chain and fittings
  • Stainless steel pump hook
  • 2 metres of delivery hose
  • 2x 1” hose tails
  • 2x Stainless steel 1” jubilee style clips
  • 1x 90° 1” to 32mm MDPE fitting
  • DN100 rubber tank seal

The DAB Divertron 1000 and 1200 pumps are direct pressure pumps, meaning that if it is connected to a tap and the tap is opened, the pressure within the system will drop and the pump will initiate. When the tap is closed, the pressure will build and the pump will turn off.

The pump delivers approximately 4 bar of pressure and up to 3500 litres/hr of flow and features dry run protection as standard. However, a float switch is retrofitted at the factory alleviating any low-level dry running issues, making this a reliable, simple system.

Pump features:

  • Built-in electronic pressure switch and flow sensor
  • Dry run protection and built in non-return valve
  • 15 metre power cord
  • Weight 11 kg
