Pollution source control by water utilities – characterisation and implications for water management: research results from England and Wales
MetadataShow full item record
The treatment of agriculturally polluted water to potable standards is costly for water companies. Changes in agricultural practice can reduce these costs while also meeting the objectives of European Union (EU) environmental legislation. In this paper, the uptake of source control interventions (SCIs) by water and sewage companies in England and Wales as a means of controlling agricultural pollution is investigated. Data were gathered using semistructured interviews with water and sewage company representatives. Interview data were processed using thematic and content analysis. Results showed that SCIs are increasingly being adopted in England and Wales. Of the four types of SCI identified, the so-called 'Liaison' type dominated. This type of intervention requires intermediary organisations with local expertise in water catchments. Differences in pollution source control between EU countries, and England and Wales are examined. Evidence indicated that 'Liaison' SCI s types may be more prevalent in countries where water supplies are privatised.
