2. Strategies for reforming the utilities3. Tariff setting policy and related issues
List of Challenges / Changes
• Decentralization• Economic transformation• Lower consumption / production• Inefficient operations• Degrading infrastructure• Accession to the EU• Problems with water resources
Decentralization of Public Services
Local, and not central decisions about most questions of operation
More suited to local circumstancesSelf-financing, no more central government subsidies• but there are some exceptions: e.g. in Hungary
disadvantaged areas with high operating costs get subsidiesFragmentation of companies• in Hungary 33 water utilities in 1990, more than 300 today• driven by differences in costs – a mix of new tariffs instead of
past uniform tariffs Confronting interests of local governments as owners, regulators,
customers, and political actors:• good quality service• low tariffs• dividend• no lay-offsTariff increases are less likely to happen in election years
Economic Transformation in Central and Eastern Europe
• High inflation, especially in the 1990s– water and sewage tariffs often lagged behind costs– depreciation of assets does not keep pace with inflation
• Poor credit facilities initially– but improved lately
• Open economies– world market prices prevail, e.g. recent surge in fuel
costs
• Unemployed population– lower consumption– unpaid bills
• Migration of workers– lower household water consumption– loss of skilled employees
Economic Transformation in Central and Eastern Europe
• Industrial facilities – shut down or face financial problems - lower demand for
water, unpaid bills– experience competitive pressure - water conservation to
save costs– introduce new technologies – decreased water use
• Example: sugar industry in Hungary - all major factories shut down during the last 15 years
• General infrastructural problems may also have an impact on water services
– E.g. Electricity shortage in Albania

Consequences of Lower Consumption
In most places there is a variable tariff system less revenue
Lower production somewhat lower operating costs, e.g. less
chemical used
Existing capacities (water extraction, treatment, pipelines, wastewater treatment) are underutilized
higher unit costs sometimes redesign needed
Low Operating Efficiency of Some Water Utilities
• Workforce – low productivity, too many employees, motivational problems
• Poor organization of working routine• Old technology – high fuel consumption, loss
of water• Poor administration, e.g. database of
consumption and payments– e.g. Inkassator in Karlovac
• Certain skills are missing:– e.g. modeling capacities, advanced financial
planning, sometimes management skills
Operating costs are too high - but there is room for more efficient operation, reduction of costs
Degrading Infrastructure Due to Poor Finances
Focus on emergency repair instead of regular maintenance and replacement
• Service may become less reliable• Quality of water may get worse• Network loss may increase• Wastewater backflows• Inefficient wastewater treatment
Creates a vicious circleIt gets more expensive to provide service e.g.
– have to pump more water because of leakage– old machinery consumes more energy
Revenues may be lower e.g.– Unreliable water meters
Accession to the European Union
Regulatory requirements:• Drinking water quality• Wastewater collection• Sewage treatment• Full cost recovery• Integrated planning of river basins (Water Framework
Directive)EU regulations also coincide with local interests:• Protection of water resources and nature• Sustainable services• Economic efficiencyEU also provides investment grants, but• Grants are not sufficient to satisfy all needs• Operating costs also increase, sometimes substantially
Problems with Water Resources
Climate change -> more volatile rain pattern, longer arid periods
• Climate change forecasts• Example from outside of CEE: recent water shortage
in BarcelonaMultiple water uses (agriculture, water utilities, industry,
transportation, hydro power etc.)• Coordination problems• Decisions are rarely made with economic rationale• Example: water abstraction fee in HungaryPollution of water bodies• Accidental pollution: cyanide in the Tisza river in
2000• Sewage discharge: drinking water of Bucharest
polluted by Pitesti
Part 2
1. Key challenges for water utilities in the process of transformation
2. Strategies for reforming the utilities3. Tariff setting policy and related issues
Main Groups of Reform Strategies
• Metering of Consumption• Invoicing and Collection of Tariffs• Improved Management of the Utility• Cost Saving Investments• Independent Performance Audits• Benchmarking• Private Participation• Reforms at the Regulatory Level
Metering Reforms
Introduction of water metering and consumption based tariffs
• Costs of water meters and their installation• Lower consumption – lower operating costs• More equitable scheme – payment can be linked to
consumption• Improved acceptance of future tariff increases
Switching to water metering within apartment buildings• The building itself has already been metered• Individual apartments get a direct incentive to mind
their consumption• Lower consumption – lower average household bill –
lower revenues in the short run• Lower operating costs
Metering Reforms
Calibration of meters• Regulatory requirement in many countries• Increase trust of consumers• Reduced the gap between metered amounts and
actual consumption
By-pass meters are planned in apartment buildings in Karlovac, Croatia
• Large diameter meters (for big apartment buildings) cannot measure low flows precisely
• “By-pass” meter has two meters. For low flows a smaller, more precise meter, for high flows a larger meter.
Metering Reforms
Other reforms connected to metering• Garden meters to measure consumption of water
that will not reach the sewer• Big industrial facilities: water consumption and
wastewater discharge as separately metered• Metering of pollution loads at the industrial
discharge points into the sewer, usually based on samples – pollution charges can be introduced
• Automated meter reading through radio signals – this technology is becoming cheaper and cheaper – quicker and no human error
• Less frequent reading of meters
Invoicing and Collection of Tariffs
Integrated information system of invoices and payments – to know the exact situation
Example: after the first careful examination of records in one of our case studies, the water company found out that about 20% their own employees did not properly pay the water bills.
Invoicing as internal or outsourced activity• Large utilities in CEE often outsource meter
reading and invoicing to specialized companies, selected through competitive bidding
Invoicing and Collection of Tariffs
Strategies to deal with non-payment and delayed payment:• Issuing a reminder after the payment deadline has
passed – requires up-to-date records• Selling the debts to debt collection enterprises• Well publicized legal procedures• Installation of low pressure valves• Cutting off service - depends on the regulations on
access to drinking water – public wells in the vicinity• Publication of the names of non-payers• Social tariff schemes• Prepaid water – with automated meter reading this is
becoming an option• Discounted debt payment• Community relations – explain the strategy for active
collection of bills and the consequences of non-payment
Invoicing and Collection of Tariffs
Methods of invoice payment• In cash at the consumer – most expensive
method, but sometimes the only practical one• In cash at the customer service• Postal cheque• Individual bank transfer • Authorized collection from the bank account
Incentives to choose bank transfers. • E.g. discount from the invoice; participation in a
lottery
Improved Management of the Utility
• Incentive based compensation – annual assessment of the performance of employees
• Management incentives provided by the owners• Internal performance targets
– Example: Nyirsegviz in Hungary has such targets for time need of emergency repairs, and speed of network rehabilitation (meter/day)
• Outsourcing of certain activities after competitive bidding
– For example meter reading, invoicing, laboratory tasks, vehicle maintenance, information technology
• Reduction of redundant workforce• Strategic and annual planning• Introduction of standards (e.g. ISO 9000, 14000 series)• Investigation of illegal connections, water as well as
wastewater
Cost Saving Investments
• Repair of network sections to reduce water loss– Does not always reduces costs. E.g. Karlovac, Croatia water is so
cheap that savings in operating costs do not reach the investment costs
• Replacement of old technologies with new, fuel efficient ones– E.g. Water pumps, vehicles
• New technological procedures– Debreceni Vizmu in Hungary in a research collaboration
developed new bacteria and chemicals to be used in wastewater treatment during the summer season. Savings of chemical costs and energy
• Process engineering– Example: Nyirsegviz in Hungary – Water and wastewater flows are registered real time, electricity
consumption is modeled for the next 15, 30 minutes, 1 hour– Electricity tariffs are based on keeping a predetermined schedule
broken down to 15 minute segments– Electricity consumption is influenced through controlling
water/wastewater flows
Independent Performance Audit
• To reveal cost saving and revenue enhancing opportunities
• Independent – no interest in keeping existing practices
• External expertise and experience
Benchmarking
• Water utilities compare various aspects of their performance to identify areas for improvement and to share best practices
• The process of benchmarking:– Develop the concept of benchmarking (which areas to
investigate, what data to collect, determine participants)– Supply data– Evaluate data, make corrections– Compute indicators– Compare indicator values across participants– Learn from best practices

Benchmarking
• World Bank water utility benchmarking exercise – IBNET
• www.ib-net.org• 85 countries, more than 2000 utilities• About 70 indicators• In-country and inter-country comparisons• Participating countries from CEE:
– Hungary, Czech Republic, Romania, Croatia, BiH, Moldova and Albania
– Planned extension: Montenegro, Slovakia, Poland, Bulgaria
Private Participation in Water Utilities
Advantages:• Municipality or state receives instant revenue instead of future
dividends• Additional access to capital for the utility• Sharing of risks between the municipality and the investor• Privatization is often accompanied with specific reforms, e.g.
service contract between the utility and the city, tariff schedule• Additional reforms are more likely to happen, e.g. metering,
billing, invoicing, cost reductions• New owner may bring useful experience, know-how
Disadvantages:• Long term agreements – difficult or costly to break• Financial achievements (e.g. cost saving) to be shared with
investors• Questions about the fulfillment of long terms goals, such as
protection of water bases, replacement of infrastructure
Private Participation in Water Utilities
Percentage of privately operated water and wastewater service in the World
• The Netherlands 0%• Germany 4%• United States 15%• France 80%• England 100%
In CEE some major privately operated utilities:Budapest, Bucharest, Zagreb (wastewater), Sofia,
Prague
Reforms at the State Level
Central tariff administration:• Should be less bureaucratic• Depreciation to be allowed to be fully covered• Novel tariff designs to be accommodated (e.g.
fixed tariffs)Taxation• Effluent charges to be linked to pollution – to
reward efforts at pollution reduction– Croatia – m3 based effluent charges
• Water abstraction fees to be based on resource scarcity, renewability
– Hungary – abstraction fee depends on activity too
Investment grants are not used efficiently

2. Strategies for reforming the utilities3. Tariff setting policy and related issues
Sequence of Tariff Reforms
Metering of consumption is a prerequisiteIdentify the purpose of the reform• Cost recovery?• Equity among customers?• Savings for rehabilitation or future expansion?• Social considerations?Select tariff designs• Simple variable tariff• Fixed tariff component• Block tariffsAnalysis, modeling of tariff reformDetermine tariff levelsPublic consultationIntroduction of new tariffs, with other, supporting reforms
Tariff Designs
• Simple, variable tariff: EUR/m3 – most common in CEE• Fixed and variable tariff: EUR/month + EUR/m3 after
consumption.– Variable tariff may not always apply to the first few m3/month
• Increasing block tariffs: tariff blocks, the price rises with consumption. Especially at places with capacity problems (water sources or infrastructural bottlenecks)
• Decreasing block tariffs: tariff blocks, the price decreases with consumption. To reflect economies of scale.
• Pollution charges based on measured or estimated pollution releases. Mostly applies to industrial facilities on the sewer.

Cost Recovery
• Customers should recover the costs associated with their service – to ensure sustainable services
• Economic justification – to avoid overuse• EU requirement (Water Framework Directive)• Cost recovery for major customer groups
eliminates cross-financing between– Customer categories: households vs. industry
The case of the Karlovac Brewery
– Customer categories: permanent vs. seasonal consumers
– Services: water vs. wastewater– Geographical locations: e.g. inner city, suburb
Levels of Cost Recovery for the Utility as a Whole
• Operating costs (e.g. labor, eletricity, chemicals, fuel)
• ... + maintenance, replacement of existing infrastructure
• ... + upgrade of infrastructure including extension
• ... + environmental costs
Affordability
How will low income households pay their water and wastewater bills?
• Increasing block tariff for all customers – first part of consumption is cheaper, then it becomes more expensive. Also helps to conserve water resources
• State subsidies to household consumption at locations with high costs (e.g. polluted water resource; small, isolated villages) – Czech Republic, Greece, Hungary, Slovakia
• Reduced wastewater charge, or at a flat rate, sometimes linked to property value (Belgium, Japan, Netherlands)
• Social water tariffs for selected groups, such as the poor, or large families
• General income support – and the family will make the consumption choices
ASTEC Model – Account Simulations for Tariffs and Effluent Charges
• Developed under the UNDP/GEF Danube Regional Project
• Purpose: Automated calculation of the physical and financial consequences of changes in the operation of W&WW utilities
• Tool for structured analysis of operational changes, investment projects, and policy reform proposals
• Based on the spreadsheets of Excel, Solver, and Visual Basic
• “Freeware” (anyone can use it without paying for it), but needs a fair amount of learning before effective use
Data Need for Impact Assessment of Tariff Reforms
Knowledge about customer categories e.g.• Number of accounts• Consumption level and pattern• Outstanding revenuesDetailed knowledge of present and future costs• By activities (water, wastewater, ...)• By cost types (investment costs, operating costs)• By customer categoriesResponse of customers to changes in tariffs• Elasticity of demandOther considerations• Ability to pay• Regulatory requirements

Cost Saving Potential in Karlovac
Measures:• Restructuring collection of revenues• Better organization of work – lower labor costs• Lower leakage of water from the network• More efficient machines and equipment• Automation of water monitoring and dispatch
system• Subcontracting repair and maintenance
Potential size of cost reduction is about 2 HRK/m3, equivalent to 25% of baseline, and 10-12% of future household tariffs
