A new approach to rainwater management is the claim being made by the County Durham-based CA Group for its recently launched Caskade Hydra system. The system is designed to allow rainwater to be rapidly routed away from large building roofs while eliminating internal pipework.
The high capacity hydraulic system features sealed rainwater chambers built into the body of the specially calibrated gutters, meaning discharge pipework is not required inside a building.
It has been tested by the University of Sheffield, whose engineers have built a full-scale operating test facility and by UKAS, the United Kingdom Accreditation Service.
