person has a clear picture of what the change looks like, rate this person’s knowledge or level of training in these areas on a 1 to 5 scale.
In this area evidently IWA methodology should be foundation for knowledge build-up, but also we need to expand and integrate additional new know-how (for example here presented Change
Management methods, general company management, and document management).
Of course important will be also new kills about technology (DMAs, pressure management, measuring, monitoring, leak detection, pipe location, GIS, mathematic modelling, AMR).
Considering the skills and knowledge identified in the previous question, evaluate the person’s ability to perform these skills or act on this knowledge.
Rate this person’s ability to implement the new skills, knowledge and behaviors to support the change on a 1 – 5 scale.
Here is very important understanding of required time for implementation. Learning and applying new skills and knowledge takes time. Use of new technologies requires investments. We need
to have clear vision and strategy (plan) how to implement change, what are the goals, how we will know when we reached them (performance indicators, evaluations, milestones). We are living in a constantly changing environment (new knowledge, new technologies, economic situation, social situation, political influences) and our capacities for adaptation and flexibility will be very important.
This is critical element of change. Without carefully planned and then dedicatedly implemented reinforcement plan, previously conducted steps can fall short. List the reinforcements that will help
to retain the change. Are incentives in place to reinforce the change and make it stick? Rate the reinforcements as helping support the change on a 1 to 5 scale.
Within reinforcement elements most important is support from top manager (general manager of the water utility). With his/her support we can count on structural change needed within the company,finances, guaranteed rewards scheme, improved communication (regular meetings, practical use of performance indicators) and recognition that our measures and activities have purpose. In majority of water utilities in our region involvement of general managers creates difference between successful and unsuccessful companies. This issue is very delicate especially considering that many general managers are politically elected to manage public utilities.
First of all water losses (and with losses related repair works, lost income, high maintenance costs, etc.) must be presented through financial perspective (not just in m3 but also in euro or local
currency). Next step is to establish regular update of information’s regarding costs produced by high water losses (monthly balance). Then, regularly we must present success examples and fi nancial outcomes (with cost-benefit analysis). Change champion must realize that he/she is the only one who can do this promotion toward top manager.
No one can or has capacity for this. Eventually one alternative exist; to hire outside consultant/expert who will influence top manager.
This is often very successful option. Reason or this is rather simple and sometimes absurd; top manager has high level of distrust in lower management and in combination with own arrogance and low level of personal knowledge in the subject of water losses creates impossible conditions for change. Here can be very important role of outside consultant (beneficial will be water loss expert/or company, but who has also knowledge in change management), since he comes with credentials and can overcome communication dysfunction within the utility.
When we have defined and organized change management process as described in previous chapter, next phase is implementation.
Implementation should be organized with following elements:
Making sense of change:
We must be result oriented what in water loss management is easy to do. Important to mention is that anticipated results must logical and rational (do not overestimate your capabilities, this can ruin your credibility toward top manager). Start small, build experience and con fi dence, build trust from top manager, build communication channel.
Using tools for change:
We must be aware that some management tools are necessary for successful change process. Here is list of them (many tools exist and here is possible selection, for more research Project management):
Roles and responsibilities
Explaining each of these tools is beyond scope of this paper, and those of you interested will need to look for explanations in widely available management resources (Google is best place to
We just need to measure, monitor and gather data, produce PIs and evaluate results after particular improvement measure was implemented (volumes of water, burst frequency,
financial aspects, KPI – for guidelines use IWA Performance indicators). We must have ability to compare situation (PI) before and after some measure was implemented. So, start measuring
and data collecting as soon as possible (before starting to change things). This way you will gather valuable data to compare with when results come.
In previous chapter was advised to evaluate people regarding ADKAR model. Use this evaluation (from 1 to 5) to analyze gaps. This will help you to understand dif
fi culties and to consider different options. It is necessary to develop gap monitoring plan.
For every problem there exists a solution. An important advice is development of good communication channel between all sides should be involved. Most of the problems in companies are related with poor communication and misunderstanding.
Create Change Managers:
Recognizing people within the company with capacities and motivation to lead change process is very important. Creating change process is one thing (and can be initiated
and developed by one person), but running it is different. We need more people motivated to take responsibilities and even more important, those who will take initiative.
Every person is important, no matter what position he/she holds. Good ideas and recommendations can come from anybody. Those people must be
rewarded and encouraged (important element of Reinforcement planning). The more people rise-up to the level of change developer, higher are chances your plan will proceed and accomplish
long term sustainability (and goals of course).
Having more people actively involved (not as passive executors) improves one of the key elements in any project – communication.
Public recognition for accomplished results is final and also critical success factor. Contributors in success must have public recognition in own company. Here is again important role of top manager. A top manager must express satisfaction and admiration with people (teams and whole departments) who have accomplished good results.
This should be done each year, and if and when particular projects are fi nished and results are known. In water utilities is complicated to establish good financial reward scheme, and minimum
what can be done very easy (and with no costs) is to have public recognition.
Of course this needs to be based on clear rules and with consideration regarding all employees in the utility. Best way is to establish PIs system for each employee and function, and emphasis should be given to those who have added value to their work (innovation, motivation, etc.).
Evaluation should be organized in a way that beside PIs, additional values can be rewarded from colleagues, supervisors and coworkers.
Example of Success
Pula Water Utility, Croatia, 900 km Network: Equipping, organizing and training personnel (trainings, seminars, conferences, literature, etc.) for activities of leakage detection are part of the regular annual improvement program and are identified from year 2004 as a key element of the strategy.
The management of the company has a clear understanding that only trained, organized and motivated people can achieve results, and technology is only a tool that can help in that.
Communication among key managers and with general manager is regular (daily) and proactive. Leakage control has been organized using a special service team for leakage control
fi eldwork (2 teams with 4 workers in total). They use all today available equipment – ground microphones, correlators, mobile flow and pressure meters,pipe locators. Important to mention is that
ground microphones and other frequently used equipment is regularly replaced every 5 years.
Targeted night-time acoustic testing of pipelines is carried out extensively each year in May and June, the oldest parts of the system and elsewhere where frequent leaks were detected is necessarily examined. These tests are conducted by a team for leakage detection and another team works during the day to resolve reported leaks. The rest of the year two teams cover the activities of reported leakages and unreported leakages i.e. monitoring the DMA zones (and testing in zones when an increase in the minimum night flow is noticed).
From 2004 till 2013 NRW was reduced from 34.5% to 22.8%. Considering problems in presenting losses in percentage Waterworks Pula introduced use of other indicators based
on IWA methodology (ILI, CARL in liters/service connection/day) and for 2013 ILI was 2.9 (among the best waterworks in Croatia). The volume of NRW in 2004 was 3.77 Mm
3, and in 2013 it was 1.94 Mm 3, making a difference of 1.83 Mm3 (48.5% savings in volume), but making also a financial impact by reducing expenses for more than euro 700.000 in one year!
Water Loss Management is complex and continuous activity. For utilities to succeed (and that means to maintain losses on acceptable level), it is important to recognize that people make change. Technology helps, but without good and motivated people there is no long term success.
Some general recommendations for water utilities:
Importance of Water Loss Team:
In today’s water utilities becomes evident need to have permanent Water Loss Control Teams. In small utilities maybe this team requires only one or two persons, but it must be recognized that water loss control is one of most important activities in any water utility.
Top Managers must realize that water loss control is not just leak detection, but today involves many additional activities like; flow and pressure measuring, pressure control valves control and
maintenance, data gathering, data analysis, reporting, use of advanced tools like GIS, SCADA, AMR, involvement in network design (DMAs, PMAs, pumping protocols, measuring locations) etc.
Position and Influence:
Water Loss Team should be part of Maintenance Department or closely related with it. In addition, people responsible for water loss control should be actively connected with Planning Department since they have firsthand experience with the network and can give valuable recommendations in new network design (and reconstruction of existing network).
As mentioned before, active communication (horizontal and vertical) is crucial and from this point everything else proceeds. So water loss team members or leader must have excellent and regular communication up to the top manager in the water utility.
Leadership and Staffing:
It is advisable that jung engineer (technical sciences) lead water loss team, considering complexity of responsibilities and needed know-how, but in small utilities this
role can be performed also by someone without university degree. Important to emphasize is that very important foundation for anybody involved in water losses is good knowledge about water
network (pipes, valves, basic hydraulics) and perfect solution to start with, is to have older employee who knows network well and new jung
employee who is friendly with new technologies and computers. To become expert in water loss control takes time (couple of years).
Number of people in a team depends on the network size, complexity, level of losses, number of DMAs, pressure management, available leak locating and measuring technology, level of knowledge, costs, etc.
In today’s conditions and with networks becoming larger and older various technologies are needed for water loss control teams.
Following equipments are necessary:
Leak locating correlators
Mobile ultrasonic flowmeters
Mobile pressure loggers
Leak noise loggers
Number and variations for mentioned equipment depends on the network and people responsible.
Important is to have established policy of regular replacement of old or used-up equipment (for example for ground microphones every 5 years, for correlators every 5-7 years, mobile meters
every 7-10 years).
Education must be constant and planned. Our water networks become more complex every day, and in the same time technology we use for water loss control become more sophisticated as well. Water loss issue requires various know-how and time factor is very important (personal practical experience).
Various performance indicators can be used (for more details see IWA PIs), depending on level of development
in particular water utility, but for beginning key numbers to look for are; volumes of water according to IWA water balance, ILI, CARL, pressure, MNF.
Very important is to collect data about leaks (reported and unreported) and establish burst frequency index for pipes and service connections.
Managing water loss control team in water utility company in context of South East Europe is very complex issue. High water losses ware mainly related with neglected position and importance of
people responsible for leaks detection.
It is important that key people and top managers in water utilities realize that water loss control teams are essential and crucial for successful control and reduction of water losses. Companies
who are successful in water loss control have very good management in all aspects of water supply and water loss control teams are highly valuable and respected.
