Event description

Belfast Wastewater Treatment Works is one of eight major wastewater treatment works around Belfast Lough located in the Duncrue | docks area of the city and is the largest wastewater facility owned and operated by Northern Ireland Water. It was built in two stages between 1992 & 1999 and serves the city centre, as well as parts of south and west Belfast.

The plant was designed to treat a domestic and trade population equivalent (PE) of 290,00, using a conventional Activated Sludge Process (ASP) prior to discharge into Belfast Lough. However, recent flow survey figures put the actual PE at over 500,000, resulting in it severely exceeding its capacity to treat effluent and meet existing discharge standards.

To resolve this issue, work has been undertaken as part of the Living With Water Programme (LWWP) to add two additional aeration lanes to the process, which should be operational later in 2024. As well as providing more treatment capacity, it will allow Northern Ireland Water to carry out essential maintenance on the existing aeration lanes which has not been possible due to the increase in PE.

Northern Ireland Water are hosting this in-person site visit organised by the CIWEM Norther Ireland new members’ group.

CIWEM members and non-members are welcome to attend this technical site visit, which is aimed at those who are interested finding out more about the work undertaken at the Belfast Wastewater Treatment Works and how this helps to deliver the aims of the Living With Water Programme and protect the Special Protection Area, SPA and Shellfish Water Protected Areas in the Belfast Lough.

Please note that as this site handles wastewater effluent, visitors should wear PPE while on the site, including a Hi Vis vest/jacket and a hard hat.

Part of the CIWEM Wastewater and Biosolids series.
