3 1. Introduction What Is Capacity? <Comprehensive Process> Capacity = Capabilities for handling issues = Set of various elements including the institutional, policy and social system Society scale (Social environment, institutional/political environment ) Organization scale Individual scale 3

4 Necessity of Capacity Assessment To improve overall capability of water utilities and water sector Assessment of current capacity and performance Project of the Japan International Cooperation Agency (JICA) Conducted by the Japan Water Research Center () and Nihon Suido Consultants Co., Ltd. The report is available on the JICA Library website. 4

5 2. Purpose of the Handbook Providing Capacity Assessment (CA) Tools Water Utilities + Water Sector (Supervisory & Regulatory Organization) 5

6 3. Methodology of Capacity Assessment Features of the Capacity Assessment Methodology (1) Capacity + Performance + Impact C : Capacity Ability of staff for water quality control & using water quality analyzers P : Performance Utility can control water quality. I : Impact People can obtain safe water. 6

7 Features of the Capacity Assessment Methodology (2) Quantitative + Qualitative Quantitative Indicators Qualitative Questions Mutual complementation (3) Expansion of assessment target scope Analysis of core capacity Accessibility of poor urban areas to water (4) Dialogue tool with the stakeholders in a developing country 7

8 4. Goals of Capacity Assessment Tools Water Sector CA of sector agencies Analysis mainly by qualitative questions Which one is the problem? CA by comparison of water utilities within a country Analysis by quantitative indicators 8

9 Assessment Items for Respective Targets Water Utility General information Pair CA for understanding outline In more details CA for detailed analysis (including improvement status) Analysis mainly by qualitative questions Multiple analyses by both quantitative indicators and qualitative questions Analysis by qualitative questions followed by quantitative indicators 9

10 Supplementary Tool Basic Tool Composition of Assessment Tools Goal of Assess -ment Goal A : Understanding Entire Water Sector Goal B : Understanding Outline of Water Utility Goal C : Understanding Details of Water Utility [1]List of Performance Indicators [2]Sector Checklist Environmental Scan [3]Utility General Form [4]Utility Basic Checklist [5]Utility Detailed Checklist [1]List of Performance Indicators Environmental Scan / Capacity Vulnerability Analysis 10

11 5. Examples of Using Basic Tool Case studies of using Utility Basic Checklist for grasping outline of water utilities capacity Each question is graded on five scales below. Level 1: Very serious Level 2: Serious Level 3: Not good enough Level 4: Good (target level of developing country) Level 5: Very good (level of developed country) Evaluation of Levels and the scores through on-site discussion with stakeholders Accurate results and capacity development 11

12 Questionnaire Items of Utility Basic Checklist (1) Category Overall Question Q1: Existence of Long or Mid-term Plan Q2: Continuity of Supply Aspects to be Improved Mainly by Facility Investment (FI) Expansion Rehabilitation & Replacement Water Supply Service Coverage Purification Plant Conditions of Facilities Q3: Overall Water Supply Coverage Q4: Water Supply Coverage over the Poor Q5: Reserve Capacity of Purification Plant Q6: Conditions of Civil Structures Q7: Conditions of Trans. & Distrib. Mains Q8: Conditions of Service Connections Q9: Conditions of M&E Equipment 12

13 Questionnaire Items of Utility Basic Checklist (2) Aspects to be Improved Mainly by Capacity Development (CD) Category Technical Aspects Nontechnical Aspects Aspects to be Improved Mainly by Sector Approach Overall Distribution Network Management NRW Reduction Water Quality Control Financial Improvement Organizational Development Public Relations Question Q10: O&M of the Facilities Q11: Drawings of Distribution Network Q12: Zoning of Distribution Network Q13: Water Pressure at Supply Points Q14: NRW Ratio Q15: Installation of Customer Meters Q16: Installation of Bulk Meters Q17: Water Quality Tests at Purification Q18: Drinkability of Tap Water Q19: Cost Recovery Level Q20: Collection Ratio Q21: Rules for Human Affairs & Incentives Q22: Implementation of Training Q23: Public Complaint Handling Q24: Public Awareness Enhancement Q25: Laws and Regulations on Waterworks Q26: Sewerage Coverage 13

14 Case Studies in Urban Water Utilities Small City B Pop. Approx. 0.18million Water Supply Coverage Approx. 73% Large City C Pop. Approx. 5.6million Water Supply Coverage Approx. 82% 14

15 Sector Approach Q1: Long / Mid-term Plan Q2: Continuity of Supply Q3: Supply Coverage Q4: Supply over the Poor Q5: Reserve Capacity Q6: Civil Structures Q7: Trans. / Distrib. Mains Q8: Service Connections Q9: M&E Equipment Q10: Facilities O&M Q11: Drawings of Network Q12: Zoning of Network Q13: Supply Pressure Q14: NRW Ratio Q15: Customer Meters Q16: Bulk Meters Q17: Water Quality Q18: Drinkability Q19: Cost Recovery Q20: Collection Ratio Q21: Human Affairs Q22: Training Q23: Complaint Handling Q24: Public Awareness Q25: Laws & Regulations Q26: Sewerage Coverage Target Level Case in a Small City B Average Score Overall Expansion Rehabilitation & Replacement Technical Aspects Non-technical Aspects Improvement by Facility Investment Improvement by Capacity Development Overall Level of the Water Utility

16 Recommendations for Small City B Capacity development focused on Level 1 and 2 items Facility investment in line with mid/long term plan Improved management of mechanical and electrical equipment, control of water distribution pressure, and human resources development 16

17 Sector Approach Q1: Long / Mid-term Plan Q2: Continuity of Supply Q3: Supply Coverage Q4: Supply over the Poor Q5: Reserve Capacity Q6: Civil Structures Q7: Trans. / Distrib. Mains Q8: Service Connections Q9: M&E Equipment Q10: Facilities O&M Q11: Drawings of Network Q12: Zoning of Network Q13: Supply Pressure Q14: NRW Ratio Q15: Customer Meters Q16: Bulk Meters Q17: Water Quality Q18: Drinkability Q19: Cost Recovery Q20: Collection Ratio Q21: Human Affairs Q22: Training Q23: Complaint Handling Q24: Public Awareness Q25: Laws & Regulations Q26: Sewerage Coverage Target Level Case in a Large City C Average Score Overall Expansion Rehabilitation & Replacement Technical Aspects Non-technical Aspects Improvement by Facility Investment Improvement by Capacity Development Overall Level of the Water Utility

18 Recommendations for Large City C Making future investment concentrating on the facility expansion such as increasing capacity of water treatment plants 18

19 6. Conclusions Features of Capacity Assessment in an Urban Waterworks Field (1) Covering both urban water utilities and water sector (2) Assessing all capacity, performance and impact (3) Quantitative indicators combined with qualitative questions (4) Broad areas for analysis (5) Emphasis on dialogue with stakeholders 19

20 Future Improvement and Expansion (1) Practical application in developing countries Improvement of CA methodology (2) Not considering different water sources and treatment methods Possible to combine CA with more detailed assessment method 20
