IWS in Jordan

Continuous Water Supply

Intermittent Water Supply

• Jordan is one of the most water-scarce countries.

• Most of the distribution networks are supplied intermittently.

• Average supply duration is 2-3 days per week.

• Very high infrastructure replacement costs due to supply conditions

‒ Delivered September 2018

‒ Project Owner: Water Authority of Jordan/Ministry of

Water and Irrigation

‒ Under the Water Management Initiative Project (WMI)

‒ Implemented by the Arab Countries Water Utility

Association (ACWUA)

‒ International consultant: B. Charalambous

‒ Local consultant: M. Shafei

Jordan NRW Master Plan

Physical losses:

• Pressure management: Extreme difficulty in stabilizing and pressure during supply periods.

• ALC: Extreme difficulty in using leak detection techniques. Impossible to apply DMA Minimum-Night-Flow monitoring.

• Speed of repairs: Difficulty in locating reported leakage when the network is depressurized.

• Asset management: High deterioration rate, uncontrolled cross-connections, and unpredictable asset conditions.

IWS and NRW Management

Commercial losses:

• Metering accuracy: High meter deterioration rate,

some customers with air registration.

• Control of Unauthorized consumption: Extreme

difficulty in locating illegal connections, high

dissatisfaction rates increase the number of

cases.

IWS and NRW Management

Reliability

Any solution or standard presented herein is focused on

increasing the reliability of water supply systems in Jordan.

Therefore, the solution targets:

– Intermittent water supply

– Lack of sufficient maintenance capacity

– Lossy data infrastructure

– Risk of infrastructure and equipment vandalism

– Lack of NRW-focused design standards

Key Values

Accountability

Any solution presented herein is focused on delivering the impact sought from the investment by establishing the groundwork for an accountability system that ensures the data, reporting, and accountability targets needed under the current and future local conditions that include:

– Lack of enforceable responsibility over NRW targets in water utilities

– Lack of management-by-results approach.

– Lack of understanding of the lifecycle of NRW management

– Lack of incentives to utility upper management and staff

– Improper use of NRW percentages to establish targets and benchmarks

– Lack of accurate operational data

Key Values

Sustainability

Any solution presented herein is focused on sustainable performance and maximizing the benefit of infrastructure investments. Therefore, the solution targets:

– Lack of established internal management reporting system for monitoring and assessing NRW

– Lack of association between operational data and supply zones

– Lack of focus on daily NRW related activities in favor of reactive complaint response

– Shortage of qualified and incentivized staff

– Prevalent belief in magical solutions such as network replacement or smart meters
