November 24, 2021
Kubota Corporation

Kubota Construction Co., Ltd., (a wholly owned subsidiary of Kubota Corporation; Head Office: Naniwa-ku, Osaka City, President: Noriyuki Arakawa, hereinafter, “Company”) is pleased to announce that it has been awarded a contract for the Project for the Expansion of Water Supply System in Luang Prabang City, the main capital city in the northern part of the Lao People’s Democratic Republic.
This project is part of the ODA Grant* signed by the Japanese and Lao governments in October 2019.
Making maximal use of technology and know-how acquired over many years in the construction of water supply systems in Laos and other parts of Asia, the Company will help to improve the water supply capacity of Luang Prabang City.

  • ODA Grants are a form of financial assistance whereby funds are provided to a developing country to support development of facilities and other activities necessary for economic and social development.

1. Background and Objectives

  • The Lao government has set a goal of increasing water supply coverage to 90% in the central areas of cities nationwide by 2030.
  • Luang Prabang City currently meets that water supply coverage target but the city faces problems in supplying adequate water quality due to leakage and insufficient water pressure resulting from aging of reticulation reservoirs and pipelines in the city center, as well as high-turbidity water caused by inadequate capacity of the Nam Khan Water Treatment Plant, which is responsible for supplying water in the area.
  • The city, which is registered as a World Heritage Site, attracts some 650,000 tourists annually (as at 2017) and is expecting water demand to increase. Thus, it is imperative to secure a sustainable and stable supply of safe water.
  • This project will include rehabilitation and improvement of the existing Nam Khan Water Treatment Plant, construction of a water distribution reservoir, and expansion of the city's water distribution pipelines, thereby increasing water supply coverage from 90.2% (as at 2017) to 96.2% (by 2025), with the population served by piped water expanding from approx.. 59,000 (2017) to some 71,000 people (2025). The project will contribute to development of a sustainable urban environment in the city by improving the water supply capacity through stabilization of water volume, and enhanced water quality and pressure.
