Implications of Changing Groundwater Quality for Water Resources and the UK Water Industry- Phase 3: Financial and Water Resources Impact

Price: £10


Ref: 04/WR/09/8
ISBN: 1-84057-343-0

This national study shows that groundwater quality problems in the UK have cost the water industry £754  million (at 2003 prices) since 1975. Costs are based on the need for blending, treatment, and source closures. Currently about 2450 Ml/d, almost 50% of the groundwater used for public supply, is affected by groundwater quality concerns. This reflects a combination of deterioration in groundwater quality and more stringent regulatory standards for drinking water. Extrapolation using two alternative scenarios suggests that future capital investment costs could be between £73 million and £180 million for each 5-year AMP period. Further, by 2027, the volume of water treated or replaced may have doubled. If treatment is to be curtailed under the provisions of the Water Framework Directive, capital costs of the order of £2 billion seem likely for alternative sources of water.
