Implementing Zonal Management Approach to Urban Water Supplies
RATIONALE
Some 700 million people in the Asia and Pacific region still lacks access to improved water supply.
People who are not connected often spend 15% of their household income for water. They buy their water from neighbours at inflated costs, or get it from standpipes or stand-posts, where access to water is only available for short durations.
The core issue is getting connected to piped water promptly and on affordable terms, especially for the poor. Once connected, people are likely to pay only 1–2% of their household income for piped water.
Unfortunately, it is not so easy to improve operational performance of the whole distribution network.
A possible solution would be to sub-divide the network into smaller, more manageable hydraulically isolated zones. This would enable operators to focus resources and efforts within each zone, thereby increasing the chances of improved performance, reduced levels of non-revenue water (NRW), increased water conservation through effective consumer revenue metering, and more. The savings resulting from these service efficiencies could be directed to adjacent zones and the process progressively repeated until the whole network has been covered and overall performance improved.
This is the “zonal approach” to urban water supplies.

OBJECTIVES
The zonal approach’s main objectives can be summarized as follows:
- 24-hour piped water to all
- Affordable water
- Conservation of resources
- Sustainability of service
- Speedy implementation of development
Top
SCOPE
The zonal approach should not be implemented in isolation but must always be part of an integrated package that includes:
- Policy and the Political Enabling Environment
Government endorsed and civil society informed policy on service levels, tariffs, tariff revisions, subsidies, private sector participation, etc.
- Technical, Financial, and Organizational Analysis
Covers water source and hydraulic zone selection, water audit, and assessment of financial viability, organizational and social aspects, and environmental impact.
- Project Management and Procurement
Project and utility management covering the development of people through leadership and strong management, with managers free to manage without political interference, as well as the procurement of services.
- Operational Management
Based on management at the lowest practicable level, for example sub-zone caretakers.
