We design systems for water supply and sanitation that help buildings work better for occupants, owners and the environment. Our public health engineers tackle varied challenges – from fire suppression systems and drainage in high-rise buildings to supplying ultra-pure water and piping specialist gases and fluids for healthcare, science and industry facilities.

By thinking beyond standard solutions, we shape performance-based systems that help our clients achieve their aspirations – from stunning design to ease of maintenance to LEED®, BREEAM, NABERS and Estidama ratings.

Our drainage system design helps to shape high-quality mixed-use spaces, for example in Renzo Piano’s London Bridge Tower, known as the ‘Shard of Glass’. Its apartments, hotel, restaurants and offices sit on top of each other, but our design gives them independent systems of drainage, ensuring that maintenance on one system will not impact other tenants.

The design also ensures reliable water supply up to the 87th floor of the Shard’s spire – more than 280m above ground level. To avoid the need for installation and upkeep of specialist high pressure fittings, the final solution ensured water pressures remain typical throughout the development. 

Responsible with resources

From sustainable drainage systems to water reuse, our expertise helps clients to make better use of water and energy, and to make their buildings more resilient to threats to their core services. Innovative water and wastewater system designs are increasingly what drive sustainability credentials, such as the LEED Platinum rating for Kroon Hall, the Yale University School of Forestry and Environmental Studies. Kroon Hall’s potable water use is an 81% improvement from the LEED baseline.
