In June 2001 Dublin City Council commissioned the greater Dublin strategic drainage study, GDSDS, a multi-million euro engineering study of the strategic drainage requirements of the greater Dublin area. Given the history of flooding in the Tolka and on the initiative of the Office of Public Works, the city council agreed to include a study of the Tolka in the GDSDS. The flooding element of the study is funded by the Office of Public Works at a cost of €870,000. The study is expected to be completed in May 2003. Surveying is now completed and the consultants are commencing work on the hydraulic model of the catchment. Meath and Fingal county councils are also participating in the study.
