The implementation of leakage reduction measures is one of my Department's key strategies for ensuring an adequate supply of good quality water to all users. A number of initiatives to give practical effect to this strategy have already been completed and others are under way or planned.
The most comprehensive study undertaken here into the operation and management of water supply systems was carried out in the Dublin region in 1995 on my initiative and that of my Department. It covered more than one third of households and its main purpose was to assess existing levels of service and water supply problems in the Dublin region and to advise on the cost effective future development of the water supply networks. It was commissioned in the belief that leakage reduction measures should be central to developing an investment strategy to meet the future water needs of the region.
One of the key findings of the study was that more than 40 per cent of the water produced in the supply systems in the Dublin region was being lost through leaks. The consultants recommended that comprehensive works be undertaken to significantly reduce the level of loss. On foot of this recommendation, I approved a five year programme of works in April 1996 costing £32 million with a view to saving approximately 22 million gallons of water per day, or approximately half of the current loss. Dublin Corporation is well advanced in the procedures for awarding the contract and the European Commission, in recognition of the real benefits to be achieved from the project, approved Cohesion Funding for it in July 1996. Since completion of the study, Dublin Corporation has already intensified its leaks control systems, including employing a contractor to undertake specific works which, to date, has saved almost two million gallons of water per day.
Studies of the water supply networks in the cities of Galway and Waterford were commissioned by my Department in October 1995. The results of pilot tests, which covered approximately one third of each city, have shown leaks running at approximately 60 per cent of the total water demand. The studies are well advanced and final reports are due to be completed within a matter of weeks. The final reports will be set out in a programme of mains rehabilitation and leaks control and they will be given urgent consideration by my Department when they are submitted. Similar projects were completed in the last few years in Dundalk and parts of County Meath under the European Commission funded SPRINT programme. In addition, projects under my Department's resorts initiative have been completed in Tramore and commenced in Westport.
The benefits arising from the leakage reduction measures identified in the final report of the Dublin study and the interim reports from the studies in Galway and Waterford confirm the need to make a national assessment of the condition of water supply systems. Plans are well advanced for engaging consultants to undertake a national water audit to determine for each local authority area, among other things, the need for new measures to reduce leakage. Results should be available by the middle of next year.
A number of specific projects are also being advanced in the cities of Cork and Limerick and in County Wexford. Proposals submitted to my Department by the local authorities concerned envisage that almost seven million gallons of water a day can be saved by implementing these projects which are due to start this year under my Department's water and sewerage services capital work programme. Local authorities generally have been provided with copies of a guidance manual prepared by consultants on ways to reduce leakage and have been invited to put forward proposals in this area. A number of such proposals have been received and are under consideration in my Department.
