Phnom Penh Water Supply Authority

Defining a GIS data model + data integration
Reorganising service process
Training staff and users

2 450 km of water supply networks
+ 140 km of additional network per year



With its 1,500,000 inhabitants, 1800 km of water mains, 270,000 service connections and an annual water supply capacity of 145 million m³, Phnom Penh, the economic and political center of Cambodia, possesses an extremely efficient water supply system. Whilst the average non-revenue water level is more than 25% in France, for instance, it doesn’t exceed 6% in Phnom Penh. The city has become a leading example in Asia in this respect.

Within the framework of the “Greater Phnom Penh Water Supply System” project, which aims to structure water service within the metropolitan area, PPWSA acquired the service of Altereo informatique to set up a GIS for the management and capitalization of the information relating to drinking water production and distribution infrastructures.


Project Description

KIS Water is a ‘full web’ solution offering the whole feature panel traditionally proposed by desktop GIS software. KIS Water provided the PPWSA managers and operators with a complete ‘water supply’ toolbox, ranging from navigation and topology features to the management of workflows.

Furthermore, KIS Water is expected to be a turnkey solution delivered to PPWSA. In addition to this, KIS Admin is an additional module for customisation. GIS specialists and system administrators will have a simple and ergonomic tool to:

  • model and integrate data,
  • manage users and rights, and
  • set up applications, forms and even workflows

It will allow PPWSA to directly manage the evolution of the system according to new requirements, including data exchange with third-party applications in different formats.
