Water derogation

In its widest sense, the word ‘derogation’ refers to an exemption from, or relaxation of, a rule or law. When the term derogation is applied to the subject of water management, it is defined as “The abstraction of water that prevents a person entitled to a protected right from abstracting water to the extent authorised on their licence.”

Additional guidance on water derogation in England and Wales is available from Ofwat, which defines a derogation as “a direction from Ofwat which relieves a licensee or appointee from compliance with certain of its obligations to comply with the Wholesale Retail Code (WRC) either as a result of it entering into Wholesale Contracts or as a result of the operation of the Stapling Condition. The power to grant derogations from compliance with these specific obligations will be introduced when the WRC is issued by the Authority.”
