Blue Roof for Sustainable Drainage

At McAleer & Rushe, our project team at Wembley is installing a blue roof with ICB Projects to comply with Sustainable Drainage requirements (SuDs). The blue roof attenuates water and releases the water slowly into the local sewage system, relieving pressure from the system during storm conditions.

With the growth of urbanisation and growing lack of natural filtration options for rain water, this puts immense pressure on urban drainage systems and at times can cause flooding when capacity is reached.

A blue roof can alleviate drainage networks restricting and reducing flow rates of water from the development into drainage system. Furthermore, the blue roof can reduce the amount of cooling required in the summer and heating in the winter, providing some thermal assistance to the hotel.

The blue roof on our project will be built with a green roof. The green roof is made from recycled plastic pallets, elevating it from the attenuation area for the blue roof, so that water can be collected, and overflows installed to prevent any flooding on the roof.

This fantastic initiative allows us to meet our SuDs and ecological requirements for the project; demonstrating our continued commitment to building a sustainable future!
