3. Potable Water – Domestic Demographics: Domestic Population served = 119,000 Average household occupancy = 2.6 Number of households = 55,311 Domestic demand per property = 390 litres per day Average Daily domestic demand = 21.57 million litres

4. Non- Domestic demand = 11.4 million litres Total daily demand (Accounted for Water), i.e. domestic & non-domestic = 32.97 million litres Average daily volume of water supplied to Cork City plus contiguous areas = 67.8 million litres Unaccounted for Water (UFW) = 34.83 million litres (51%) Potable Water – Non-Domestic

7. Cork Drainage Catchment Carrigrennan

8. Water Service Investment Programme Works Completed to-date City Watermain Network Replacement programme in conjunction with Cork Main Drainage works – 9m (4.7m recouped from DOECLG) City divided into 47 District Meter Areas (DMAs) UFW varies from 22% to 64% in DMAs Cork Main Drainage scheme – 340 million

9. District Meter Areas

10. Water Replacement & Rehabilitation Study Proposals: Creation of District Meter Areas Update Hydraulic Model and GIS Develop system for condition and performance grading of individual mains Prioritisation of DMAs for Watermain rehabilitation and/or replacement

11. Rehabilitation Study: -20 DMAs and 28 high priority trunk mains requiring significant replacement/rehabilitation -Daily saving of 15.5 million litres of potable water at present being lost through the network -Reduced production and network maintenance costs - Reduction in unaccounted for water levels to 28% - Reduction in callouts for leaks to watermains -Reduced pressure to acceptable levels across all DMAs

12. Water Service Investment Programme Contracts listed to Start by 2012 Lee Road New Waterworks – 17.5m Network Rising Mains to Reservoirs - 1.9m City/County network Interconnector – 2.9m Docklands Water Supply Scheme - 5.6m St. Patricks Street Culvert - 0.5m Watermain Rehabilitation Stage 1 - 12.6m Elimination of Backyard Services - 2.75m
