A complete garden underground rainwater harvesting system package direct from the manufacturer.  The 6800 litre is generally suitable for the medium to larger sized applications.   Our sales team will be able to confirm the most suitable size for you if you wish.

Storage tank details

6800 litre underground storage tank, complete with pedestrian rated telescopic neck and lid, push fit DN100 drainage connections. Made from virgin polyethylene plastic, ribbed for strength and in most cases, installed without the need for concrete.

Physical dimensions of the tank

Height 1250mm x Width 2700mm x Length 3420mm

In-tank filter

The system comes with a choice of in-tank filters.

1) Compact filter suitable for roof areas up to 150M2

2) PF filter suitable for roof areas up to 200M2

The filter is pre-installed into the neck of the tank, where is it joined to the also pre-fitted calming inlet. This filter removes leaves, grit and other debris from the incoming water to approximately 1mm.  Finer particles form a "scum layer" and are washed away during overflow or filtered out by the secondary filtration.  The filter is easy to clean, usually about 3-4 times per year.  There are no consumables, just lift, rinse and replace.

Pump and controls

The submersible pump is suspended from a pre-fitted hook in the neck of the storage tank by a stainless steel chain.  It comes with a high quality large handle, for easy lifting if necessary.  The pump delivers approximately 4 bar of pressure and up to 3,500 litres/hr of flow.  The pump is started automatically as the point of use  and has dry run protection as standard.  There is also an optional upgrade, click on the graph below to see the difference in the performance between the pumps.
