DMSI 7 Water management

Surface water management

1.

As a minimum all development must:

  • utilise permeable surfaces (including on areas of public realm and on small surfaces such as front gardens and driveways) unless they can be shown to be unavoidable
  • have regard to advice from the Council as the Lead Local Flood Authority (LLFA) as to their preference and guidance on Sustainable Drainage Systems (SuDS).

2.

Development proposals should aim to achieve greenfield run-off rates and ensure that surface water run-off is managed as close to its source as possible in line with Policy SI 13 of the London Plan 2021 and the drainage hierarchy. All major development must incorporate SuDS into proposals, where appropriate, having regard to the government’s latest Non-Statutory Technical Standards for Sustainable Drainage Systems and the Council’s latest Strategic Flood Risk Assessment (SFRA).

3.

Minor developments are also expected to incorporate SuDS, where feasible. SuDS should provide multiple benefits and integrate with the Council’s green infrastr ucture network.

4.

Proposals for SuDS will also need to include a long-term SuDS Management and Maintenance Plan, including details of who is responsible for maintenance.

Water infrastructure

5.

All new development is required to minimise the use of mains water, water supplies and resources in residential and nonresidential development in line with Policy SI 5 of the London Plan 2021: Water Infrastructure and the Optional Requirement of the Building Regulations (residential development). The use of rainwater and grey water to minimise the use of mains water will be encouraged.

6.

The Council will support development proposals where they:

  • consider the net increase in mains water and wastewater demand to serve their developments and engage with Thames Water through the free pre-planning service at an early stage to confirm that there is adequate capacity to serve the development. The outputs of the communication can be included as evidence to support a planning application
