Living With Water Programme Risks, Issues and Aims Risk / Issue Plan Aim (Outcomes) 1 Flooding Reduce the risk (Protect) 2 Compliance with Environmental Legislation 3 Constraint to economic development due to lack of drainage & wastewater treatment capacity 4 Assets require essential maintenance Maintain 5 Climate Change Adapt Comply (Enhance) Enable growth (Grow) 6 Amenity potential lost Increase amenity value 7 Drainage operational costs a burden Optimise 8 Capital constrained Invest efficiently
Risk / Issue 1: Flooding All risks at 1 in 100 ( Surface River Sea ) A: 2.8bn

A: 2.8bn Every development and new connection: Increases foul flow Increases impermeable area, runoff & storm water flow rates Flooding: Increased likelihood of flooding + 88 Belfast properties on NI Water s Out of Sewer Flooding Register Combined Sewer Overflow Discharges: Tunnel should spill less than 15 times per year However spills more often + spills from over 90 other Belfast overflows Risk / Issue 3: Constraint to Economic Development Wastewater Effluent Treatment Discharges: Belfast WwTW design capacity: 300,000 PE Current loading: over 360,000 PE + Current consent is relaxed, likely to be more stringent
Risk / Issue 3 Constraint to Economic Development Impacts Impeding growth Limited new business No new housing Construction Revenue NI Reputation
Risk / Issue 4: Assets Require Essential Maintenance East Belfast drainage area: 62.5km surveyed for PC15, 5.5km assessed as collapse likely, imminent or occurred (300 locations) 22 July 2014: Ravenhill Road to remain closed as more holes found Risk / Issue 5: Climate Change Future Impacts on Sewer Systems in England (2011): The combined effects of climate change, growth and urban creep will lead to a median increase in 1:10 year sewer flood volumes of 51% by around 2040 compared with current predicted flooding
EU Water Framework Directive Long Term Water Strategy Drivers for an Integrated Investment Planning Approach PC15 Business Plan Development Process
NI Executive Long Term Water Strategy (LTWS) Future Focus: Sustainable Shared Solutions Firstly: Resolve ownership & capacity of private infrastructure Storm water separation Infiltration reduction Increase capacity of watercourses Then: Implement conventional solutions (bigger sewers, tanks, WwTW) Investment drivers shared by: River or Culvert B Road
Opportunity: Department for Infrastructure (May 2016) DRD Functions (incl. NI Water Transport NI, NITHC) Crumlin Road Gaol Team Inland Waterways (from DCAL) Department for Infrastructure Rivers Agency (from DARD) Vehicle Regulation, Road Safety and DVA (from DoE) Strategic Planning and Planning Policy (from DoE)
Living With Water Programme Scope & Progress Phase 1 Development of the Belfast Strategic Drainage Infrastructure Plan Phase 2 Development of the NI Integrated Drainage Investment Planning Guide and Programme 1) July 2014 - Executive agree to develop SDIP 2) Jan 2015 - LWWP Board established 3) Oct 2015 - Work Packages Defined & Commence
LWWP Board Members Visit to the Metropolitan Glasgow Strategic Drainage Partnership (June 2015) Bringing Glasgow to Life

Living With Water Programme Main Capital Outputs 1) Private drainage infrastructure ownership defined, brought up to standard 2) Storm separation - progressed for some parts of Belfast 3) Sewers - capacity increased & maintained 4) Watercourses capacity increased, maintained, increased amenity value 5) Drainage infrastructure - designed for exceedance 6) Combined Storm Overflows some closed, others improved 7) Sewage pumping stations - upgraded or replaced 8) Storm storage - increased 9) Belfast WwTW - upgraded Other activity will include: Catchment management measures to reduce diffused pollution Increased used of sustainable drainage systems (SuDS)
