2. Objective of the IWRM approach is not water
management as such
but human development.
IWRM approach can only work
if it does not focus exclusively on water.

10. Application of IRWM tools in WSS
• Managing Demand and Supply (C3.1-3.3)
– Better efficiency of water use and better efficiency of water supply
• Technologies exist
• Metering and pricing systems act as incentives
• Education and communication campaigns should target direct users
– Recycling and resuse
• Technologies exist but are very costly and not always user-friendly
– Sustainable sanitation concept
• Ecological sanitation
• Open waste water planning

12. Application of IWRM tools in WSS
• Better governance and institutional reforms (B1 and
B2)
– Camdessus: ”increasing financial flows will make no
sense unless there is an equally effort to reform the
way the world tackles its water problem” – pouring
new $ into old managment will not be sustainable
solution.

C7.1-7.3
14. Application of IWRM tools in WSS
• Role of economic instruments (C7.2-C7.3)
– Internalize external environmental costs
– Incentives for environmental investments
– Cost-effective pollution control
– Raising revenue

17. Why do we need a Case study?
Theoretical description
Synthezied memory
Practical implementation
18. Typical format of case study
1. Problem(s) to be addressed
2. Actions taken
3. Outcomes (expected & unexpected, impact of action,
resources needed, sustainability of outcomes)
4. Lessons learned (what is useful for others)
5. Links and other supporting information/publications
19. Criteria for the case study
• Cases are not limited to “good” stories – “bad”
stories are also welcomed
• Cases should
– illustrate the application of IWRM tools
– have overall relevance to IWRM – with lessons
about how an IWRM approach supports water
management across sectors
– Reflect both pros and cons
20. What is not a case study
• Something what did not happen (“theoretical”
issues, recommendations, advise)
• Guidelines on how and what should be done
• Something what did not bring the results (good
or bad) – reports on workshops, conferences
21. What did I see at students papers:
• Title: Improvement of sanitation in XX town
– Analytical part (details about needs to provide local citizens with sanitation;
technological aspects, level of treatment and pollution control, enginnering
solutions)
– Synthesis part (recommendations to City Hall to build infrastructure)
– Why sanitation service?
– Alternatives? (involvement of other sectors, including energy sector!!)
– Who pays for investments? Who pays for O&M running cost (taxes, fees)?
– Sanitation & Water supply (two integral services)
– Stakeholders analysis, involvement?
– Future demands (increasing/decreasing)
