Outline of the Project

Project Name

The Federal Capital Territory Reduction of Non-Revenue Water Project

Implementaiton Organisation

Federal Capital Territory Administration (FCTA)
Federal Capital Territory Water Board (FCTWB)

Target Area

Federal Capital Territory (FCT)
Pilot Areas: Gudu, Jabi and Garki I

Project Period

October 2014 - September 2018

Project Background

Water supply services has not met water demand due to rapid growth of urban population in Nigeria, as a result, access ratio to improved water source is decreasing in urban area from 79% in 1990 to 74% in 2010 (Unicef, 2012). In particular, one of the Federal Capital Territory (FCT or Abuja) is 41% in 2011 (IBNET, 2011), which is much lower than nationwide access ratio, because of mass-migration into FCT to seek employment. Specifically, population is 2.15 million and its annual growth is 4.7% in FCT (Demographia, 2011).

Another challenge FCTWB has confronted is high ratio of non-revenue water (NRW) at approximately 40%. Although FCTA set the target of NRW ratio at 25% by 2015 in strategic plan (2011-2015), FCTWB has not taken effective measures due to lack of technology for NRW reduction and knowledge of planning. Monetary loss by NRW is estimated at about JPY 800 million (USD 7.3 million, October 2014) per annum. Water supply facility has been developed based on the existing plan applying NRW ratio at 20%, so current status of NRW causes difficulty in water supply services according to the plan as well as increasing access ratio to improved water source. FCTWB is a division of FCTA and expected to be autonomous in the future, of which a bill for an act was submitted to national assembly, so strengthening of management framework is an urgent issue.

The Project aims at enhancement in NRW reduction capacity of FCTWB through the following outputs and ultimately NRW reduction in FCT:

  1. Regular monitoring of level of NRW in water supply service area of FCTWB
  2. Establishment of methods and operational procedures for effective NRW reduction (leakage, water meter malfunctioning and illegal connection) through pilot projects, and
  3. Development of a medium-term strategic plan of NRW reduction particularly by utilizing the above outputs.

Japan has assisted Nigeria in the field of rural water supply, but the Project is the first assistance in the field of urban water supply.


Overall Goal

Level of Non-Revenue Water (NRW) is reduced at the service area of FCTWB.

Project Purpose

Capacity of FCTWB for NRW reduction is strengthened.


  1. Level of NRW of both the service area of FCWTB and water distribution areas is monitored regularly.
  2. Methods/operational procedures for effective NRW reduction are established through pilot projects at Pilot Metering Areas (PMAs) under pilot Area Offices.
  3. A medium-term strategic plan of FCTWB for NRW reduction is developed, utilizing the results of Output 1 and 2.

Main Activities

1-1 Install bulk meters to water treatment plants 1 and 2
1-2 Measure monthly water production of water treatment plants 1, 2, 3 and 4
1-3 Tally the above water production data monthly
1-4 Calculate the monthly water consumption based on the billing data
1-5 Calculate monthly NRW ratio of the service area of FCTWB using the data obtained from Activity 1-3 and 1-4
1-6 Install zonal meters, water pressure sensor and pilot remote monitoring (telemetry) system
1-7 Measure and collect data for water distribution management such as water flow of zonal meters and water pressure
2-1 Review existing NRW reduction operations at each pilot Area Office
2-2 Conduct capacity assessment of the relevant staff of each pilot Area Office
2-3 Identify and select a Pilot Metering Area (PMA) for each pilot Area Office based on the selection criteria of PMA
2-4 Prepare/update distribution network drawings for each PMA
2-5 Install water flow-meters to each PMA and measure in/outflows monthly
2-6 Zone each PMA into Sub Metering Areas (SMA)
2-7 Isolate a SMA by installing valves
2-8 Update the distribution network drawings for each SMA
2-9 Measure an initial level of NRW of each SMA
2-10 Detect target NRW components (i.e. invisible leakage, customer meter malfunction, and illegal connection) of each SMA
2-11 Develop a NRW reduction operation plan of each SMA, including reduction target, for review by Head of Distribution Department
2-12 Review and approve NRW reduction operation plan of each SMA
2-13 Implement the NRW reduction operations at each SMA
2-14 Monitor the progress of the NRW reduction operations of each SMA
2-15 Measure level of NRW of each SMA at the end of the respective operations
2-16 Prepare a report on pilot projects, covering Activity 2-1~2-15
2-17 Develop manuals for NRW reduction for Area Office managers and field operators (i.e. technical officers and meter readers), including audio visual materials
3-1 Establish a Working Group for NRW planning
3-2 Review existing plans, implementation structure, on-the-job training mechanism, etc. related to NRW reduction at FCTWB
3-3 Conduct hydraulic and water pressure distribution analyses of the pipeline networks
3-4 Develop outlines of the medium-term strategic plan and its annual NRW reduction plan
3-5 Develop the first medium-term strategic plan (2018-2022) for approval by FCTA
3-6 Develop an annual NRW reduction plan based on the strategic plan as an integral part of an annual recurrent and capital plan of FCTWB for approval by FCTA
3-7 Develop a planning manual for NRW reduction
3-8 Review existing plans, activities and implementing structure, etc. related to water distribution management
3-9 Establish framework of water distribution management
