A Waitrose store in Stratford-upon-Avon has utilised ACO Water Managements Qmax® slot drainage system and KerbDrain®, a combined kerb and drainage system, to effectively manage surface water on the new car park and the approach to the store.
ACOs Qmax® 225 was selected, as the slot drainage can be easily integrated into a SuDS application and allows for the fast, efficient removal of water from the surface, as well as eliminating carry over in storm conditions. As a back up solution for the permeable paving, the Waitrose site required a high capacity attenuation system. Qmax® was perfectly suited water can be stored at source within the product, allowing for a much slower and more controlled discharge of water to surrounding drainage networks, so that they do not become overwhelmed, leading to possible flooding
ACOs KerbDrain® system was selected; a one-piece combined kerb and drainage solution specifically developed to form an integral part of any modern, sustainable surface water management scheme. The versatility of KerbDrain®, including its selection of depths from 255mm to 480mm allows engineers and designers to create a solution to optimise the specific hydraulic and performance requirements of a roads drainage scheme, making it much more efficient.
