The unique flat tank can be installed into higher water tables than a standard round tank. The installation depth is 60% less than other rainwater tanks, whilst excavation can be up to 70% less, meaning less earth excavation and less cost.

The tank can be installed without the need for costly concrete bases or back filling, simply site on 100mm of compacted aggregate and back fill with similar material.

Positioning is flexible and each tank comes with a 635mm shaft that can be cut on site to achieve the required invert level. A pedestrian rated manhole cover is provided for the top of the shaft. Steel shaft and cover available on request for use in driveways or other areas where vehicles may need to drive over the tank cover.

The low energy management system pumps through a control unit, up to a ‘smart header tank’ usually situated in a loft space. Inside the header tank are two level sensors, upper and lower. The system fills the header tank to the upper sensor then does not use the pump again until virtually all of the water is used and the lower sensor is reached. This ‘batch filling’ process means the pump cycles 1-2 times per day, in comparison to every time a toilet is flushed with traditional systems.

Full mains override provides water in the event of low rainwater, pump failure or power cut.

Water companies now recommend, and in some cases require the use of black and green HDPE pipe to transfer the collected rainwater to the outlet/s. Each rainwater system comes with a 25m coil of 25mm black and green HDPE pipe as standard.
