Further downstream, the catchment is dominated by urban areas (e.g. Saggart, Citywest, Clondalkin, Bluebell, Inchicore and Kilmainham) with residential, industrial, and commercial land use. Many sections of the lower reaches of the river are culverted and channelised. Site investigation works will take place across the jurisdictions of both DCC and SDCC.
