Environmental performance is a priority for developers of the prestigious new Meltonwest Business Park on the rural outskirts of Hull, who have used Hydro-Brake® Flow Control technology to engineer a natural solution to surface water drainage.
Hull-based developers the Wykeland Group chose a sustainable drainage solution to regulate the expected high surface water flows created by the increased impermeable surfaces on the 50-acre site discharging into an existing open watercourse.
Aiming to achieve pre-development flow rates, two Hydro-Brake® Flow Control devices were installed to regulate the discharge from two balancing lagoons. The two Hydro-Brakes are located at the outfall of each of the lagoons to help control the onward flow of the watercourse as it continues its journey away from the site and towards the River Humber.
“Wykeland is committed to sustainable design on Meltonwest and all of its business parks,” said Wykeland architect Graham Aitchison. “Sustainable features will be incorporated into all the business units, and a sustainable travel co-ordinator has been appointed. The surface water drainage scheme has been designed to utilise the existing watercourse, by regulating the discharge with Hydro-Brake® Flow Controls supplied by Hydro International.”
When complete, the business park will accommodate approximately 14 mixed-use buildings, which with surface yards and car parks will cover an impermeable area of some 35 acres, all of which will drain into the catchment lagoons that the two Hydro-Brake® Flow Controls serve.
Andy Ringrose, Team Leader at Consulting Engineers Alan Wood & Partners added: “The drainage solution centred on widening the existing watercourse and using Hydro-Brake® Flow Controls to throttle back the flows and achieve greenfield discharge rates. The northern balancing lagoon has a storage capacity of 3,500 cubic metres and the southern lagoon of 2,050 cubic metres. The Hydro-Brake® Flow Controls regulate the outfall to the Environment Agency’s required level of 26 litres per second for the entire development.
“With flows regulated by the Hydro-Brake® Flow Controls, the watercourse leaves the site via a culvert under the adjacent railway line before flowing for a further few miles until it discharges into the River Humber.”
Meltonwest is strategically located on the A63 nine miles to the west of Hull with direct links to the M62 corridor and onward to the M1, M6 and A1. Already, well-known names have been attracted to take up the premium-quality, landscaped accommodation including a 260,000 sq ft distribution warehouse and HQ for Heron Foods, a pharmaceutical bottle facility for Paragon, and a wine distribution facility and HQ for House of Townend. The contractor was C R Reynolds Ltd.
