This 1200-litre low profile aboveground water storage tank is suitable for storing potable and non-potable water to be used for agricultural, domestic, commercial or industrial purposes. It’s ideal for those very awkward installations.

Moulded from Medium Density Polyethylene, this tank complies with UK Water Supply Regulations 1999, Water Byelaws 2004 Scotland and Water Supply Regulations (Northern Ireland). The UV stabilised polymer ensures that the tank is protected against potentially damaging effects of sunlight. The potable version is approved by KIWA Watertec and WRAS.

Various Installations – Can be used for agricultural, domestic, commercial or industrial premises.

Non Corrosive – manufactured from Medium Density Polyethylene (MDPE), Harlequin tanks will never corrode.

Protection against Sunlight – They are manufactured from UV stabilised polymer protecting the tank against potentially damaging effects of sunlight.

Slimline & Low Profile Options – For more awkward installations, slim and low to ground tank options are available.

This 1500-litre ‘Home Harvest Gravity’ rainwater harvesting system is ideal for efficient collection, storage and distribution of rainwater to be used during periods of water scarcity. It allows the connection of a hose to the pump within the tank to provide recycled rainwater for irrigating lawns/gardens, car washing and other outdoor water needs.

Moulded in one piece from Medium Density Polyethylene (MDPE), this seamless non-corrosive tank with a strong body, an adjustable turret and a calmed inlet can be installed very easily and reduce water costs by 50%. The system complies with BS8515 Rainwater Harvesting Code of Practice and Part G of Building Regulations in U.K.

It comes equipped with a rainwater distribution unit called the ‘Rain Director’ and a smart header tank. The ‘Rain Director’ system pumps rainwater from the storage tank to a header tank where gravity distributes it to the required water appliances such as toilets, washing machines and the garden, minimising on/off pump cycling reducing electrical costs and wear on the pump. Once rainwater has been exhausted, the unit replenishes the storage tank with mains water.

Reduce Water Costs – Collecting and reusing rainwater can save up to 50% of metered water costs.

Easy Installation – Our shallow tanks only require a shallow excavation with no concrete backfill, this also reduces your installation costs.

Non-Corrosive – Manufactured from Medium Density Polyethylene (MDPE), Harlequin tanks will not corrode.

Adjustable Turret – 4500 and 6000 model turrets have the ability to be extended or reduced to fit each installation.

Strong Tank Body – A seamless one piece moulded tank guarantees strength. There is a flat base for stability, moulded in lifting points and a flat load-bearing lid.

Legislation Compliant – The system complies with BS8515 Rainwater Harvesting Code of Practice and Building Regulations (Part G).

Calmed Inlet – This reduces the turbulence to tank sediment, improving the quality of water supplied.
