An outbreak of Campylobacter jejuni infection occurred in a South Wales Valleys housing estate. Illness in estate residents was associated with tap water consumption [population attributable risk (PAR) 50%, relative risk (RR) 2 center dot 53, 95% confidence interval (CI) 1 center dot 9-3 center dot 37] and residence in the upper estate (PAR 49%, RR 2 center dot 44, 95% CI 1-83-3 center dot 24). Amongst upper estate residents, rates of diarrhoeal illness increased with rates of water consumption (OR 18, 95% CI 3 center dot 5-92 center dot 4 for heaviest consumers, X(2) trend P < 0 center dot 0001). The upper estate received mains water via a covered holding reservoir. A crack in the wall of the holding reservoir was identified. Contamination with surface water from nearby pasture land was the likely cause of this outbreak. Service reservoirs are common in rural communities and need regular maintenance and inspection. The role of water in sporadic cases of campylobacter enteritis may be underestimated.
