Levels of Service Define / Review Levels of Service • Statutory - • Water Quality – SI 278/2007 • Discharge Standards – SI 684 of 2007 • Customer – • Service Pressures • Adequate Capacity – treatment & storage • Leakage/Infiltration • Fireflows
Performance Indicators Define / Review Levels of Service • Water Quality – Compliance with quality standards. • Discharge Standards – Compliance with licence or certificate conditions. • Service Pressures – % and number of connections with adequate pressure. • Adequate Capacity – % of WTPs / WwTPs with 10% headroom. • Leakage/Infiltration – % compliance with ELL / % of Infiltration. • Cost of Water Services – Cost per capita / M3
Distribution Input (DI) Domestic Demand Households x Occupancy x pcc Non-Domestic Demand Metered consumption Operational Use – 2% of DI Peaking Factor – Average Day in Peak Week / Average Day Accounted for Water (AFW) Measured or assessed legitimate water use Unaccounted for Water (UFW) = DI - AFW Demand for Water Services • Current Demand - Water Audit Demand Assessment
Dry Weather Flow (DWF) Domestic DWF Flow = Households x Occupancy x per capita flow Load = population x per capita load Accounted for DWF Measured or assessed legitimate waste water flow and load Non-Domestic DWF Flow based on water in = water out Load based on EPA Guidance Unaccounted for DWF Flow = Min night flow – metered flow – domestic allowance Load = Measured load less accounted for domestic and non- domestic load Demand for Water Services • Current Demand – Waste Water Assessment • Current Demand Demand Assessment Peaking Factor
Reduce water losses and infiltration. • Reduce water consumption and associated waste water production. Demand for Water Services • Current Demand • Demand Management Demand Assessment
Demand for Water Services • Current Demand • Demand Management • Future Demand • Population growth (25-Year Horizon) - Top Down: Planning guidelines, CSO - Bottom Up: Availability of zoned land Demand Assessment • Water & Waste Water – Domestic demand as per audit using projected pcc, losses etc. - Non-domestic demand growth in line with domestic - UFW/Infiltration in line with level of service objectives
Asset Data • Water Supply Assets (National Water Study 2000) • Source type/capacity • Treatment type/capacity • Water quality compliance status • Length of network • Number/capacity of pumping stations • Number and total volume of storage reservoirs • Value of total asset (Modern Equivalent Asset (MEA) value) • Value of assets to be replaced over next 5 years (MEA value) • Annual operating and maintenance costs Collect Strategic Asset Data
Asset Data • Water Supply Assets (National Water Study 2000) • Waste Water Assets (National Urban Waste Water Study 2004) • Treatment type/capacity (flow and load - p.e.) • Discharge standard compliance status • Length of collection system • Number/capacity of pumping stations • Number of combined storm overflows (cSO’s) • Sludge treatment type/capacity • Value of total asset (MEA value) • Value of assets to be replaced over next 5 years (MEA value) • Annual operating and maintenance costs Collect Strategic Asset Data

Identifying Scheme Options • Existing arrangements in place – Arrangements already planned or in place for meeting scheme deficits. • Operational Options – Reduction in demand through demand management or leakage through active leakage control. • Rehabilitation/Renewal Options – Increasing capacity when renewing or replacing assets that have reached the end of their useful life. • Augmentation Options – Increasing scheme capacity by augmenting from an adjacent scheme that has surplus capacity. • Replacement/Upgrade Options – Increasing capacity to meet scheme deficits by adding new infrastructure. Strategic Options
Stage 1 - SEA Scoping Report, Issue to Environmental Authorities – sets out environmental issues to be addressed in the plan. • Stage 2 - SEA Environmental Report – developed in parallelwith the draft plan. • Stage 3 – Statutory Consultation – on Environmental Report and relevant elements of Draft Plan. • Stage 4 - SEA Statement, Published with the Water Services Strategic Plan and issued to Environmental Authorities. Strategic Environmental Assessment Strategic Options
Asset Management Planning • Levels of Service –Existing & Target, performance indicators. • Demand for Water Services – Existing & projected. • Asset Inventory –As per NWS & NUWWS. • Operational Plan – Summary of primary objectives in the operational plan and any sub-plans. Asset Management Plan • Maintenance Plan – Summary of the planned asset maintenance. • Rehabilitation/Renewal Plan – Summaryof the planned asset rehabilitation/renewal activities. • Asset Replacement– Summary of theplanned asset replacement. • Financial Plan – Summaryof the projected Opex & Capex over 6-year period from the date of making the plan.
Sustainable level of expenditure to cover future investment needs Covering cash costs and providing for maintaining current asset condition – no planning for the future Just covering cash costs Financial Planning • Water Services Expenditure Requirements Financial Plan Funding for Loan Repayment Funding for System Growth Funding for Service Enhancement Funding for Historic Under-investment Asset Depreciation Interest Expenditure (if any) Operation and Maintenance Expenditure
Financial Planning • Water Services Funding Categories Financial Plan Domestic Non-Domestic Local Government Fund Water Charges Opex Water Services Investment Programme Water Charges Capex SLI Funding (40%) Development Levies (60%) Development Levies
Financial Planning Financial Plan • Financial Plan • Prepare income statement & yearly forecast. • Forecast capital expenditure on:- • asset replacement and renewal. • service enhancement and growth (new assets). • Funding requirements. • Review and set charges. • Review and update.
Plan Review & Improvement Plan Review (At least every 6 years) • Levels of Service • Demand for Water Services • Asset Management Planning • Financial Planning • SEA
