Strategic Environmental Assessment

The Strategic Environmental Assessment (SEA) is a process for plans and programmes to undergo an environmental assessment to determine the likely significant effects on issues such as biodiversity, climatic factors, human health, population, cultural heritage (including archaeology), air, material assets, landscape and water.


The Water UK guidance on DWMPs states that, as the DWMPs are strategic plans, it would “make sense to align the assessment of impacts and benefits to the requirements of an SEA, to demonstrate that the plan delivers the best, sustainable outcomes for customers, stakeholders and the environment, including consideration of natural capital / ecosystem service provision as a result of planned investment / operation.

There is not a statutory requirement to undertake an SEA for this round of the DWMP to meet the Environmental Assessment of Plans and Programme Regulations, 2004. However, Water UK guidance states that “undertaking an SEA on the final optimised plan would be ‘best practice’ and is recommended”.

We have produced our SEA Scoping Report setting out how we are approaching SEA during the development of our DWMPs:
