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

Deteriorating Raw Water Quality
Sustainable Catchment Area Management Planning (SCaMP NI) Climate Change Adaptation, Reducing Opex, Avoid Capex Good Carbon WTW Carbon Bad WTW & Extension Consequences: CO 2 emission, increased WTW capital & operational cost, reduced storage capacity, reduced summer raw water base flow, river flow more ‘ flashy’
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

Shellfish W aters) 5) EU revised Bathing W ater Directive Belfast WWTW Flooding (2012) Combined Sewer Overflow
A New Approach: York Street Area Drainage
