Kiribati Adaptation Project III (KAPIII) - Non-Revenue Water Reduction

Country: Kiribati - South Tarawa

Project period: 09/2014 - 08/2018

Client: Public Utilities Board (PUB)

Investment amount: EUR 815,245 (consulting)


This project is part of the Government of Kiribati’s Climate Change Adaptation Program III, which aims at improving Kiribati’s resilience to the impacts of climate change on freshwater supply and coastal infrastructure. The piped water supply system of South Tarawa is managed by the Public Utilities Board (PUB). Supply to consumers is on an intermittent basis, two hours every second day, due to high non-revenue water (NRW) of around 67% and limited sweet water resources.


The main objectives of this assignment are leak detection, repair of transmission mains and reservoirs, physical improvement of the water distribution systems in three pilot zones, trainings for PUB staff in leak detection and repair, introduction of a basic asset management system, as well as the establishment of a leak detection unit at the utility. Further prepare bidding documents for material and works, assist PUB in tendering and contract preparation, perform construction supervision and construction management for the works, partly implemented through contractors, partly through force account

Services provided:

  • Procurement of leak detection equipment and water supply material
  • Physical leak detection, supervision of repair works
  • Development of a repair concept for leaking reservoirs, tender documents, and construction supervision
  • Distribution system mapping and assessment
  • Network modelling and calibration
  • Establishment of a leak detection and repair unit at the utility
  • Development and introduction of an asset management system at the utility
