Stormwater Planters and Downpipes

Do something different with boring downpipes! Here’s a few examples of recent projects.

Stormwater planters can be used at the base of a downpipe or rain chain as an aesthetic solution to managing the flow of rainwater. They help to reduce flash flooding by slowing the flow and can form part of a sustainable drainage system (SuDS).

Ramsbury Primary School Rainscape

It’s raining! Watch this project come to life - a Torricelli tube downpipe, a water wheel, and three stormwater planters outflowing to a rain garden. Funded by ARK Action for the River Kennet as part of their Rainscapes initiative.

Preshute Primary School Rainwall

Preshute Primary School Rainwall

My rainwall design for Preshute Primary School in Manton, Wilts, features wiggly downpipes, with hoppers as planters, rain chains and clear sections to allow the flow of rainwater to be observed. These stormwater planters are made from cattle troughs and slow the flow of rainwater.

Designed for and funded by ARK (Action for the River Kennet).
