The Lowermoor Water Treatment Works supplies drinking water to the north Cornwall water distribution network. Raw water is obtained from the Crowdy Reservoir, which is 3/4 mile to the north east, and which is filled predominantly by run-off and drainage from surrounding moorland. The works were constructed in 1973.Subgroup report on the Lowermoor water pollution incident. Department of Health 2005
