Our capital investment programme for rivers and the coastline

Find out about work to manage flood risk from rivers and the sea

Managing flood risk from rivers and the sea is an important part of Natural Resources Wales's work and we carry out this work in several ways:

  • By building new flood defences and other structures such as sluices and pumping stations
  • By maintaining defences and structures once built, keeping them in good condition subsequently, and repairing or improving them if and when required
  • By maintaining main river watercourses, removing obstructions, vegetation and silt or gravel, to keep water flowing and remove significant flooding risks

Statutory functions

Our capital investment programme is approved by the Flood Risk Management Wales Committee. This executive committee fulfils a number of Natural Resources Wales' statutory flood risk management functions, in accordance with Section 106 of the Water Resources Act 1991. 

The programme is composed largely of a range of prioritised interventions to reduce flood risk. It also includes some recurring activities that are necessary to support these interventions.

Our flood defence work

Each year, Natural Resources Wales spends around £9m from the Welsh Government's Capital Flood Defence Grant in Aid. This is often supplemented by additional funding from the Welsh Government and external sources. In the last five years, capital investment has averaged £16 million per year.

Economic and environmental justification

Managing flood risk from rivers and the sea is an important part of Natural Resources Wales's work and we carry out this work in several ways:

  • By building new flood defences and other structures such as sluices and pumping stations
  • By maintaining defences and structures once built, keeping them in good condition subsequently, and repairing or improving them if and when required
  • By maintaining main river watercourses, removing obstructions, vegetation and silt or gravel, to keep water flowing and remove significant flooding risks
  • Appraisal of the flood risk management options for areas at risk
  • Design and construction of new or replacement defences to protect properties at risk
  • Work on habitats to mitigate and compensate for the detrimental impacts of flood defences

Capital investment programme: 2015 - 16 onwards

Unlike routine maintenance activities, which typically take place annually, capital works are part of a rolling programme of larger projects spanning a number of years. As such, the programme is based on confirmed funding in Year 1 and indicative funding beyond that period. All projects and timings listed in the programme are subject to change, based on availability of resources, economic justification, technical feasibility and risk-based prioritisation.

Consultation

Our programme is agreed after consultation with our own fisheries, recreation and biodiversity teams. This ensures that the natural environment is maintained and, where possible, improved as a result of our maintenance work.

Works near you

A programme of investment is available for consultation below. Please refer to the spreadsheets to get an idea of the scope and timing of works we currently plan to undertake near you.

The nature of capital works means that changes to stated programmes and timetables are inevitable. These changes are formally approved by the Flood Risk Management Wales Committee. The published programme will be updated following the committee's approval of proposed changes.
