The existing infrastructure and network are in a perilous state, at high risk of failure, and not fit for purpose for Ireland’s future needs. To date, a myriad of systems, processes and work practices have operated across the 34 Local Authorities (LAs). The approach to service delivery has relied significantly on personal knowledge and commitment of staff in individual LAs across the country. Management of water services delivery has suffered from incomplete or very poor data collection, inconsistent and inadequate asset analysis, varied local application of policy and standards, ad-hoc investment planning and limited application of risk management. This is not a sustainable approach to achieve effective and efficient service delivery. The establishment of Irish Water (IW) and the transfer of functions and assets, previously undertaken by the LAs, is a significant development for the State and an opportunity to deliver a more effective and efficient service. IW’s main priority, during the transfer of functions and assets, is to ensure that there is continuity of service and no negative impact on customers at this time. The focus from 2014 will be to continue with the work of the Irish Water Programme (IWP) in establishing the people, processes and systems required to deliver water and wastewater services across Ireland. IW will, during the Interim Price Control period, identify areas where opportunities for improvement and efficiencies exist and deliver them for customers. This is against a backdrop of increased pressure on operational costs due to growth in the services delivered, in particular compliance driven growth. The key challenge for IW will be to transition processes and systems from the 34 LAs, circa 1,000 Water Supply Zones (WSZs) and circa 1,100 waste water agglomerations to a single set of processes and systems in a High Performance Utility Model. Central to this will be a concerted effort to collect data on the existing assets and operations and convert it to information and knowledge that can be used to deliver affordable services to meet the needs and expectations of IW’s 1.8m customers. The Operations & Maintenance function in IW will play a key role in the delivery of safe, affordable and environmentally compliant water services to all customers. To this end, IW will require sufficient funding and resources to meet its vision, objectives and obligations. The absence of adequate funding would severely constrain the level to which services can be improved, economic growth supported and environmental compliance achieved. 4 2 Introduction This document sets out the framework, systems and processes for operation and maintenance of water services following the transfer of assets from the 34 LAs to a single national utility, Irish Water. The objectives of this submission are: . To provide an overview of operations and maintenance activities associated with the delivery of public water services prior to transfer of responsibility to Irish Water on 1st January, 2014; . To outline IW’s plans to integrate water services delivery from 34 LAs into a single public utility to improve the asset operations and maintenance function; . To outline the roadmap for improved service delivery; . To outline the measures that IW will take to improve efficiencies in the delivery of water services and highlight the impact these efficiency measures; and, . To set out the budget for Operations & Maintenance. The scope of this document includes the following: . The operation and maintenance of public water supplies from source to tap, including the abstraction, treatment, storage and distribution of drinking water and treatment and disposal of all wastes and residues; . The operation and maintenance of all public waste water services, including the collection, transfer, treatment and disposal of wastewater and the treatment and disposal of all wastes and residues. A glossary of terms and abbreviations used in this document is included in Appendix No. 1. 5 3 Background Prior to 1st January, 2014, public water and waste water services in Ireland were managed by 34 Water Services Authorities (WSAs. 3.1 Overview The IW Operations & Maintenance function will be responsible for assets which are used in the provision of water and wastewater services. They include: . The above ground assets for water supply (abstraction works, treatment plants, pumping stations and storage reservoirs) and below ground assets (trunk and distribution mains) used in the provision of drinking water for public water supplies; and . The above ground assets (wastewater treatment, sludge treatment, pumping stations) and below ground assets (foul and combined sewers, sewage rising mains and outfall pipelines) used in the provision of public wastewater services. There are 1,027 Water Supply Zones (WSZs) and 1,069 Wastewater Agglomerations, spread across the State. There is a considerable difference in the scale of these WSZs and Waste water Agglomerations as shown in Tables 1 and 2 below.

There are c. 163 WWTP, serving approximately 75% of the total wastewater load, currently being operated by private service providers; a full listing is included in Appendix 4. The DBO model has not been used to the same extent for water treatment works (WTW); there are circa 36 WTW currently operated by private service providers; a full listing is included in Appendix 5. 3.2 Legislative Background Prior to the enactment of the Water Services (No. 2) Act, 2013, LAs were defined under the Water Services Act 2007 as the WSAs and were responsible for the provision of water services in their respective areas. Prior to the introduction of the Act in 2007, the LAs provided the service in their role as Sanitary Authority, based on a suite of legislation, dating back to the Public Health (Ireland), Act, 1878. 3.2.1 European Directives The European Union has been responsible for introducing a number of Directives that impact directly or indirectly on the delivery of water and wastewater services in Ireland as they are transposed into Irish legislation. These Directives together with the Water Services Act 2007, were the key legislative instruments governing water services provision and operation in Ireland2. 3.3 Key Stakeholders – Previous model 3.3.1 Department of Environment Community and Local Government The Department of Environment, Community and Local Government (DECLG) controlled the water service capital expenditure programme. Investment by the LAs in water services was guided by the policies and procedures of the DECLG.
