Format of Presentation: G eneral Overview Providing an Efficient Infrastructure for the Supply and Disposal of Water Alternatives Sources of Supply, Storage and Disposal of Water Administration and Cost of the Supply and Disposal of Water

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 = million litres

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

Supply & Storage of Water for Cork City

Wastewater Collection from the City and contiguous County areas Secondary Treatment at Carrigrennan, Little Island 78 million litres per day from City 22 million litres per day from County Design capacity of Treatment Plant 413,000 p.e. Current loading – 310,000 p.e. 54% of load is non-domestic

Cork Drainage Catchment Carrigrennan

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

District Meter Areas

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

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

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 m Elimination of Backyard Services m
