CA’s Caskade HYDRA Specified At Wynyard Park
CA Group has been contracted to install 625 linear metres of Caskade® HYDRA at Wynyard Park, Stockton-on-Tees, by consultants Norman Disney and Young and London based architects, Househam Henderson.Caskade® HYDRA siphonic rainwater management system allows rainwater to be routed rapidly away from roofs on even the largest buildings while virtually eliminating internal pipework. The system features sealed rainwater chambers built into the body of specifically calibrated gutters, meaning no discharge pipework is needed inside the building.
The product was installed on a 26,600m2 warehouse building on the Wynyard Park development which will be used as a data centre. The over roof is to be installed by Keyclad Ltd who have employed CA Group to work on the project as a turn-key solution, providing them with the design, supply, installation and commissioning of each Caskade® HYDRA system.
Caskade® HYDRA was chosen after the original pipework installed on the building was found to be faulty. A traditional siphonic rainwater management system had been installed previously, which can suffer from problems with expansion and contraction as rainwater was previously taken from the cold exterior of the building to the warm interior through internal pipes. Due to the nature of the materials being stored within, it was vital that the water ingress issue was addressed.
Mark Walker, CA HYDRA Product Manager, explains: “Caskade® HYDRA was perfect for the building because it eliminates the many problems associated with internal pipework thanks to its innovative arrangement of two inbuilt rainwater discharge chambers – a first stage system, which drains directly into an underground system via one downpipe at the end of the building and a second stage system drains to a downpipe at the opposite end.
“The rainwater flows through individually calibrated anti-vortex inlets into the first stage system, which is designed to cater for the initial rainwater capacity of the roof. Should the first stage system reach capacity, such as in deluge conditions, the second stage system is brought into action, as an operational overflow and failsafe system to further protect the building.”
