National policy statement for waste water : a framework document for planning decisions on nationally significant waste water infrastructure

This Waste Water National Policy Statement (NPS) will be used by the decision maker (formerly the Infrastructure Planning Commission (IPC)) as the primary basis for deciding development consent applications for waste water developments that fall within the definition of of Nationally Significant Infrastructure Projects (NSIPs) in the Planning Act 2008.

The NPS sets out a justification for new waste water infrastructure and provides information on to two projects - the proposed treatment works at Deephams in North East London, and the Thames Tunnel which will carry waste water from sewage overflows which currently run into the Thames.

Under the new guidelines, applicants of Nationally Significant Infrastructure Projects will need to consider aspects such as the standard of design, whether any alternatives exist to the project, pollution control and wildlife conservation.

The Government is taking measures to lessen demands on waste water infrastructure in England through sustainable drainage systems.

However, more infrastructure is required to prevent environmental damage and poor water quality.
