Water quality in Scotland is excellent, but occasionally things happen that could affect water quality. Scottish Water is required to report these events to DWQR as well as local authorities and NHS health boards. Where DWQR assesses these events as sufficiently serious they are declared incidents and Scottish Water must provide a detailed report. DWQR will investigate these incidents and make recommendations or take further action against Scottish Water. Details of DWQR incident investigations are organised by year and are accessed on the left hand side of the page.
