A horizontal wellpoint groundwater source was constructed to supply irrigation water to a golf course from a coastal dune‐sands aquifer in an area which has vulnerable wetland habitats of European importance. The source was designed to abstract the required quantities with less drawdown, compared with that from a conventional vertical wellpoint system, thus reducing any potential threat to the nature‐conservation sites. Pump testing of the source showed that the yield was more than adequate to meet the needs of the Golf Club and to allow efficient operation of the computer‐controlled course irrigation system. Data from observation wells indicated that there was no drawdown beyond the golf‐course boundaries and none of the nature‐conservation sites would be affected. The horizontal wellpoint method, which has not been widely applied in the UK, could have wider applications for irrigation water users who need to abstract water from shallow aquifers.
