Rainwater harvesting and stormwater attenuation in a single system

Flatform Rainwater Harvesting has added a wall tank rainwater harvesting and stormwater attenuation system to the Halsted Rain Flatform range which the company was exhibiting at Ecobuild 2016. It is an innovative approach to rainwater management on properties where space is severely constrained or a retrofit solution is required.

The system collects rainwater run-off for toilet flushing, irrigation and/or to manage discharge to a drain or soakaway.

The ultra slim wall tank system is modular and easy to install. It improves upon a proven 2009 design and offers the following additional benefits:

1. Larger 235 litre tank modules (only 20cm deep)

2. Easier to install galvanised steel wall mounting bracket

3. Recessed inter tank connector to create a ‘seamless’ wall of water storage

4. CAD designed internal structure to carry the vertical, horizontal and lateral loads

5. Green granite and optional colours available by special order

6. New throttle valve to manage discharge rate

To be used for toilet flushing the wall tank can be integrated into a fully automatic system by adding a low energy pump and mains water top up unit. The system is said to be ideal for domestic and light commercial installations.

The Flatform Range also includes a low profile shallow dig below ground tank which offers larger capacity.

“Rainwater harvesting and attenuation systems have to be affordable, reliable and easy to install and maintain; and in an urban environment limited space makes the Flatform range a very competitive solution,” says Andrew Lennard, Director, Flatform Rainwater Harvesting.

“By combining rainwater harvesting and stormwater attenuation in a single system we aim to simplify and reduce the installed cost of these services and it is only by achieving this and expanding the market for these systems can we hope to meet national water efficiency and stormwater management targets.”
