While renewing its GIS solution for underground network cadastral data in 2011, the SIGE took the opportunity of confronting an open-source solution to generic commercial solutions. The SIGE took the risk of developing its own solution based on existing open-source GIS softwares (QGIS, PostgreSQL, Postgis), but made the most of the flexibility offered by such approach. And so was born QWAT, which is in production since December 2013.

Some communities of the surrounding area were facing the same question about renewal of their GIS solution and went visiting the SIGE to discover QWAT at its early development stage. Pully, Morges and finally Lausanne decided to join their effort and decided to perform a proof-of-concept with a live-test of QWAT into their infrastructure.

With the success of this proof-of-concept, they decided to choose Oslandia as a preferred integrating company to bring QWAT to an industrial grade quality. With its support, QWAT was brought into production in Pully and is about to be soon in Lausanne and Morges. By joining their forces and different points of view, QWAT is about to become a complete solution: easy to use, rich in terms of features, documented and with support available.
