The water companies have and will continue to make a number of representations as part of the development and review of Regional Spatial Strategies, including modifications to consider additional housing in growth areas. For example, in the recent East of England Examination In Public, Anglian Water and Thames Water both made representations to the independent panel outlining their views on the impact on water supply as a result of house building. However, such representations by water companies can be made at different stages of the planning process, both formally and informally. These are not held centrally by Government and could be provided only at disproportionate cost.
