SuDS Blue Roof Project, Manchester

Our installation team spent a large part of the summer installing a unique SuDS water attenuation system (SuDS – Sustainable Drainage) at a residential apartment block. The system is for a large podium deck at Middlewood-Locks in Salford, Manchester, an exciting and growing re-development where we are working with IPS Group

The first phase covers around 2400 sq.m. 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 work is to provide a sustainable urban drainage system (SuDs) to control water run-off; an increasing problem in urban settings as our weather turns wetter and our rainfall heavier.

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.
