mwa role
We were commissioned to design, supply and install the complete plumbing and mechanical services package to this development. Engaging with mechanical & public health specialist consultants to devise cost effective and efficient strategies across the above ground drainage and rainwater & Domestic water systems.

The Boosted cold water distribution system was quite unique on this scheme due to the high rise nature of the build. Working closely with our public health consultant we designed a system that could operate with working pressures in excess of 20 bar, whilst maintaining balanced operating pressures at each point of use. Each tower has its own domestic water plant room where high pressure booster sets are located. These booster sets pump the domestic water up and around each individual tower ensuring residents have a clean and fresh supply of drinking water at all times.
The above ground drainage system to high rise developments is often quite challenging. On this particular scheme, the drainage system used was the Terrain PAP & Pleura valve system. This particular system featured in a case study on Polypipe Terrains website.

Working closely with the Architects and the clients design team, MWA helped select a high-end specification for all traditional bathrooms, en-suite bathrooms, penthouse, and amenity areas.
The project start date for the plumbing and mechanical works was April 2019, delivering the job across a 48 month period, handing over to the client on time in June 21.
