OiEAU ANNUAL REPORT - 2019

Inter Laboratory Tests (ILE): an increased partnership with AGLAE In 2019, OiEau and AGLAE (Association Générale des Laboratoires d’Analyses et d'Essais - General Association of Analysis and Testing Laboratories) combined their resources and expertise to organize the 1 st ILE samplings in all types of water. These tests were carried out in La Souterraine, at the OiEau training center, supplemented by tests in the municipal swimming pool and wastewater treatment plant and in the Saint-Pardoux Lake. The OiEau site has real capacities for taking samples while meeting many constraints: access authorizations, beaconing, personal protective equipment, equipment, representativeness of sampling points, in situ measurements, coordi- nation of the various stakeholders. These ILEs gathered French and European participants (Ger- many, Belgium) and revealed various practices depending on the participants, while demonstra- ting that the differences were not significant. Other ILE projects are in preparation, with the objective of a biannual frequency, as from 2020. Pilot facilities & tests: at the core of the partnership with INRAE As part of the Oriented Pipe Renewal Project, OiEau provides its leak detection unit and en- riches it with new functionalities to meet the needs of the “Water Stewardship in Structures” team INRAE Bordeaux (new sections, calibrated leaks, instrumentation structure to study the ef- fectiveness of reducing water losses, etc.). INRAE Bordeaux has entrusted OiEau with the establishment of a mobile pilot facility on a trailer for quantifying water leaks, to carry out field tests. INRAE Montpellier commissioned OiEau to mo- dernize its Platform for Research in Science and Technology for Irrigation: improvement of the test bench dedicated to measuring water distribution under irrigation sprinklers. 4 modules produced by OiEau in 2015 were completed by new ones, manufactured and tested by our technical ser- vices, then delivered and put into service in Mont- pellier. Mobile and connected via WiFi to a super- visor and coupled with additional measurements (drop size, wind speed and direction, spraying rate, etc.), they allow an industry to characterize the water distribution of its irrigation sprinklers according to ISO 15886-3. It is the largest measurement bench of this type in the world! « We appreciated the availability, the multidisciplinary expertise as well as the quality support provided by OiEau throughout the construction of our bench. » Mr. Froment, Technical Manager of the Platform - INRAE Montpellier.
