Northern Ireland Water has completed work on the £1M Strafhfoyle Siphon Header Tank. The project is part of a £21.6m investment programme to upgrade the existing sewerage network within the City of Derry. Nigel McKee, NI Water Project Manager, discusses the need for the investment. "Following recommendations made in the Londonderry Drainage Area Plan 2005, key areas were identificed as requiring improvements, namely a required level of service in terms of environmental, structural and operational performance. The Strathfoyle Siphone Header tank project set out to address these issues, by upgrading the existing NI Water works through the construction of a new combined sewer overflow chamber, a new siphon header tank and storm storage tanks".
Work on the project began in September 2007 and was completed on schedule in August 2008. The investment also ensures compliance with Northern Ireland Environment Agency regulatory standards until 2030.
Major of Derry, Councillor Gerard Diver, welcomed the completion of the works. "This new facility will undoubtedly benefit the city. The header tank has been designed to ensure sewage flows through the existing siphon pipework underneath the River Foyle are maximised and continued for treatment at the newly constructed Culmore Wastewater Treatment Works. This will ensure an appropriate infrasture is in place to accomodate future growth and development in the city".
This project is a working partnership between NI Water, Sheartwater Consortium and Halcrow Faber Maunsell.
