In 2014, when it became clear that the drainage infrastructure across Belfast was unable to meet the requirements expected of it, the Northern Ireland Executive approved the development of a Strategic Drainage Infrastructure Plan (SDIP) for Belfast.

This Strategic Drainage Infrastructure Plan (SDIP) for Belfast will:

  • protect against flooding by managing the flow of water through a catchment from source to sea;
  • enhance the environment through effective wastewater management and the provision of enhanced blue/green spaces to benefit local communities; and
  • grow the economy by providing the necessary capacity in our drainage and wastewater management systems to facilitate new development projects including house building.

To develop and deliver this plan, an interdepartmental group, called the Living With Water Programme (LWWP), was established.
