NI Water - At a Glance

LTWS has Informed NI Water’s Company Strategy & PC15 Business Plan

DRD PC15 Social & Environmental Guidance NIW & CCNI PC15 Customer Views Surveys NI Water Company Strategy PC15 Business Plan DRD & CCNI LTWS Customer Views Surveys DRD Long- Term Water Strategy NI Assembly & Ministerial Input

Challenge – Constrained Capital Investment

A: £2.3bn The sum necessary to address the known current capital investment drivers by the end of the PC15 period Sums are stated in year 2012/13 prices B: £1.4bn The sum which could be efficiently invested by NI W ater in the PC15 period (subject to completion of studies & appraisals ) C: £842.5m The constrained sum available in the draft PC15 S&EG, as allocated in NI W ater’s PC15 Business Plan

B:£1.4bn A:£2.3bn C:£842.5m

Challenge – Climate Change

Flooding (Nov 2009) Drying (June 2010) 7 mths Burning (May 2011) Freezing (Dec 2010) 5 mths

The LTWS Sets out that Sustainability and Climate Change Require New Approaches 1) Water Demand Management 2) Catchment Management 3) S ustainable S ewerage 4) S ustainable WwTW

Water Demand Management

Demand Source LTWS Aim Comment

Leakage Achieve the sustainable economic level of leakage About to be achieved, will be exceeded in PC15 period. Non- household Reduce wastage through education & audits. Incentivised through metering & pricing. All in place. Domestic Current consumption 150 l/h/d LTW S target 130 l/h/d Sustained reductions only possible through education campaigns coupled with metering & billing. M etering & billing: EU - shown leadership and legislated (W FD) UK - Government policy NI - Introduction an issue for the Assembly

Deteriorating Raw Water Quality

Sustainable Catchment Area Management Planning (SCaMP NI)

Climate Change Adaptation, Reducing Opex, Avoid Capex

Carbon

Good

WTW Carbon

Bad

Consequences: CO2 emission, increased WTW capital & operational cost, reduced storage capacity, reduced summer raw water base flow, river flow more ‘ flashy’

WTW & Extension

SCAMP NI Garron Plateau Project

• 4,628ha - most extensive intact

upland bog in NI

• Important habitats (hen harrier, golden

plover, snipe, & red grouse) Key objectives:

• Restore ASSI
• Ensure appropriate grazing
• Blocking drains, preventing erosion, improve raw water, restoring hydrology
• Develop experience

The partners involved…

+ Local community groups & farmers

Next steps: CMPs for NI, EU INTEREG V Pilot led by NI and Irish Water, best practice guide

The PC15 Business Plan Sets Out the Scale of Total Investment Needs: An Appendix sets out that Investment of c£0.75bn is Required for Belfast Drainage & Wastewater Treatment Key drivers, : 1) Economic development (WWTW compliance with existing standard) 2) Flooding 3) EU UW W TD 4) EU W FD (incl. Shellfish W aters) 5) EU revised Bathing W ater Directive

Combined Sewer Overflow

Flooding (2012)

A New Approach: York Street Area Drainage

York Street Interchange drdni.gov.uk/yorkstreet

York S treet Interchange Preliminary Drainage Design

Proposed “Do Something” Option

• Storm water separation from the existing NI W ater sewerage system
• Transport NI are facilitating this work within their contract

Sustainable WwTW - Integrated Constructed Wetland (ICW) Stoneyford ICW (950 PE, £900k, Standard 15/25/3)

Stoneyford ICW Pond 2 - planted Sept 2014 Clonaslee ICW Inlet sludge pond Stoneyford ICW pond 1 – planted Aug 2014

Stoneyford ICW – June to Oct 2014

Sustainable WwTW – Willows

Agricultural Need for Sustainable Willow Effluent Recycling

Dromore Willows

Irrigation site Pumping main W wTW

£2.1m, May 2011 to Nov 2014 WwTW 2,500 PE, effluent pumped to 15 Ha willows

Conclusions

1) We are delighted with the LTWS, which has informed our Company Strategy and PC15 Business Plan

2) Sustainability and Climate Change requires new approaches, some of which need strong leadership 3) The LTWS is being implemented now

4) Success relies on all Stakeholders Working Together
