A strategy is described which was adopted to ensure compliance with the EC Directive on Drinking Water, at six rural locations in Northumberland. These areas, plus a more widespread community in the Tyne Valley, are served by Catcleugh reservoir, a typical upland coloured source. Treatment of the smaller locations was carried out by single‐stage pressure‐filter plants, and for the larger area by a two‐stage treatment works. Three of the small pressure‐filtration plants have been closed, and the supply has been replaced from the two‐stage plant. In the other three cases, two improvements are complete: one a dissolved‐air flotation scheme, the other low‐rate single‐stage pressure filtration. Improvements to the third station are in the planning stage.
