Siltbuster helps protect aquatic ecosystems around new project
Siltbuster has provided Costain with four modular treatment solutions to be used during the delivery of a £200 million (€224 million) project.
The leading water treatment specialist has been tasked with planning the water run-off management during the building of a new dual carriageway in the UK.
The route goes past several surface watercourses including the Savick Brook and the Lancaster Canal.
Siltbuster has deployed four water treatment systems to cover the multiple controlled watercourses where water is being released from the site.
Each location is regulated by the Environment Agency, with the Environmental Permit requiring total suspended solids be less than 100mg/l and a pH value between pH6 and pH9 to be achieved consistently.
The Preston Western Distributor Road linking Preston and southern Fylde to the M55 motorway, which is a 2.5 mile-long dual carriageway, is set to open in 2023.
In order to protect the north-west’s aquatic ecosystems and habitats, each Siltbuster unit needed to be capable of treating flows of up to 40m3/hr.
All of the systems include two-stage flow proportional chemical dosing of coagulant and flocculant to improve the settlement rates of the very fine suspended clay solids, and an 8m3 tank complete with mixers and a HB50 lamella clarifier.
Karl Heath, environmental manager at Costain, said: “We’ve been managing the water on site throughout the project starting with basic settling techniques. The Siltbuster systems have helped keep the project on track by ensuring we are in line with our environmental permit at all times, protecting the surrounding habitats as vigilantly as possible.”
James Baylis, regional technical sales engineer at Siltbuster, concluded: “We were able to advise on temporary flexible modular solutions which could be rapidly deployed from our hire fleet as soon as the need arose. As part of our service, we have also offered Costain specialist technical advice and training, helping to protect the aquatic ecosystems around the project.”
