DWQR and the Scottish Public Services Ombudsman (SPSO) have a potentially overlapping jurisdiction in terms of water supply complaints. DWQR is responsible for ensuring the quality of drinking water in Scotland and will consider complaints from members of the public about water quality as set out in our guidance document on Complaining about Drinking Water Quality. The SPSO can consider complaints from members of the public about their water supply where there is a claim of injustice or hardship as a result of maladministration or service failure on the part of a local authority. More information on making a complaint to SPSO can be found on their website via the link Scottish Public Services Ombudsman
