As part of the new Abraham Darby Academy, developed for Telford’s Building Schools for the Future scheme, on-site contractors Kier invited ACO Water Management to provide a sustainable drainage solution for the management of surface water in car parks 1 & 3.
It was imperative that the solutions provided by ACO were a cost-effective alternative to the porous paving solution that had been used in the construction of car park 2, which had subsequently incurred high construction costs.
The proposed solution used the Collect, Clean, Hold and Release drainage system’s principle. Consisting of four stages, the process begins with the efficient and effective collection and conveyance of surface rainwater. The water is then clean using a hydrocarbon separator, which processes any problematic substances such as silt, whilst also removing pollutants such as oil. This water is then stored to await a controlled discharge. The water is then released into the environment via and ACO Q-Brake vortex flow control, which in turn allows the system to fill the StormTank attenuation units.
ACO worked closely with Kier to ensure that all design criteria were met, and to show the versatility of the ACO product range. Kier chose ACO products due to their considerable cost savings compared to the original porous paving design, which amount to a 30% overall saving.
Speaking about ACO involvement in the project, Graham Tait, Senior Project Engineer at Kier, commented. “The ACO design made good commercial sense for the car park and the support ACO provided helped this project to run smoothly. The products were quick and easy to install and dealing with a single supplier was a real benefit.”
The ACO products use recycles materials to provide an environmentally sound solution and their compact lightweight design further reduced the carbon footprint, as there was less need for shipping of both materials to the site and of haulage waste material away.
