The sewer and drain specialist restores a stormwater attenuation tank and drainage to help de-risk the site and support future Birmingham Smithfield Development
OnSite, South Staffordshire Plc’s leading sewage and drain specialist, was called in to help Birmingham City Council, who had identified an issue with an attenuation tank at the Smithfield Birmingham Development site.
OnSite’s specialist team were asked to clean the tank to return it to serviceability and to reduce the risk of future surcharging. To complete the works, a high risk confined space entry was needed, with OnSite’s specialist in-house confined space rescue and support team present throughout.
Having cleared the tank’s blocked outgoing and released a seized outlet flap valve, the OnSite team ensured the tank was workable and also cleaned the main 1750mm diameter carrier drain, which was 60% blocked, to return it to a free-flowing state.
Ian MacLeod – director of planning, transport & sustainability, inclusive growth at Birmingham City Council commented: “With future site development in mind, it was really important for us to ensure the tank was in working order to de-risk the site and the danger of water surcharges. The OnSite team did a fantastic job in remedying this for us, and I’d like to thank them for a great, high-quality service.”
Tom Rochford, national operations manager (drainage) at OnSite added: “We were delighted to be able to support Birmingham City Council with these works. Drainage, whilst not the most obvious or prestigious element of any site maintenance, is so critical both for health and safety reasons and the reduction of potential disruption, so it was really rewarding for our team to be able to help out in this way.”
