Warrenpoint Wastewater Treatment Works Being Upgraded

摘要

NI Water has taken a major step forward in the £6m upgrade of Warrenpoint Wastewater Treatment Works (WwTW) with the 'seeding' of the new Activated Sludge Plant (ASP). Building work at Warrenpoint WwTW was undertaken by Dungannon-based GEDA Construction, while Newry-based water Solutions Ireland (WSI) were responsible for the extensive mechanical, electrical and process-related work at the site. Project management was carried out by Belfast consultancy firm McAdam Design. The extensive programme of improvements at the Mound Road site forms part of the EU-funded Shared Waters Enhancement & Loughs Legacy (SWELL) project, which aims to improve water quality in Carlingford Lough and Lough Foyle through the upgrade of wastewater assets on both sides of the border. The seeding of the new Warrenpoint plant -the process whereby flows are introduced to the new infrastructure to initiate the biological treatment process - took place over a number of days and involved pumping more than five million litres of wastewater into the new tanks.Explaining how the process works, Tomasz Piadlo, NI Water SWELL Project Manager said: "The new Activated Sludge Plant at Warrenpoint is a substantial structure built to replace the smaller 40-year-old tanks on the site. With twice the volume of an Olympic-size swimming pool, the new ASP is equipped with three aeration lanes, each with over 300 diffusers, which distribute oxygen into the tanks to break down the bacteria in the wastewater.
