Residential water attenuation project in Manchester

We’ve spent a large part of the summer installing a unique water attenuation system on a residential apartment podium deck in Salford, Manchester working with IPS Group .

Start of first phase of water attenuation

The first phase covers around 1200 square metres of podium above the car park and includes a ‘Blue Roof’ comprising of syphonic drainage, Aquaten water attenuation system and substantial landscaping. The new residential blocks, situated next to the old Manchester canal, provide a beautiful outside space for the residents, however, the key objective of the landscaping is to provide a sustainable urban drainage system (SuDs) to control water run-off.

Landscaping starts on interlocking void former blocks

The build includes over 6000 sq.m. of interlocking void former blocks with a large capacity to not only hold water but also to support the weight of the detailed landscaping.  The shrub and turf areas also have a layer of Aquaten fleece which helps hold water and provides passive irrigation for plants.

Almost completed first phase of water attenuation system

The second phase starts in the autumn and is even larger; lets hope the weather is a little cooler!
