As part of the project, SAFEWATER is committed to a user-driven iterative development process that will be performed in two trial cycles against realistic usage cases. SAFEWATER Release 1 was launched in the summer of 2015 and trialled in the second part of 2015 in 3 water utilities: Agua do Algarve (AdA), Portugal; Zürich Wasserversorgung (WVZ), Zurich and Hagihon, Jerusalem. It simulated realistic scenarios preparing the ground for Release 2 and the second set of usage cases' trials.
AdA performed their trial against Usage Case 1 - Chemical contamination of a water reservoir by an unknown organic compound caused by deliberate sabotage. The SAFEWATER solution was checked with an emphasis on the chemical sensor developed by BioMonitech. Below are images from AdA's beta site in Algarve where different reagents, bacteria and toxic organic compounds were investigated:
Hagihon performed their trial against Usage Case 2 - Radioactive contamination of a municipal storage tank by different radionuclides due to deliberate sabotage. Trials were carried out in two locations: CEA premises, testing the radiological sensor against beta isotopes and Hagihon's beta site in Jerusalem, testing the integration of the radiological sensor and the SAFEWATER solution against simulative data mimicking radiological event. Below are images from Hagihon's beta site:
In addition, Hagihon installed Low Energy Sensors (Domestic Sensors) in two separate monitoring stations to support the development and testing of the Spatial Model and Virtual Sensors' model. Images of the installation at the monitoring stations are below:
WVZ performed their trial against Usage Case 3 - Biological contamination of the secondary water main by sewage intrusion due to an accident or carelessness. The experiments included dilution experiments with waste water determining the sensitivity of different parameters for the detection of faecal contamination in tap water. For the purpose of testing the biological sensor, the SAFEWATER solution as well as the simulators, WVZ constructed a unique Beta Site, with 100m of pipelines including shafts, cross points and a smart control system. This enables WVZ to performed various tests and simulations with real case studies and support the development of software components and models (such as a hydraulic model). Images from the Beta Site can be seen below:
Similar to Hagihon, WVZ has also installed Low Energy Sensors in two seperate monitoring stations, enabling testing of the whole SAFEWATER solution including the Spatial Model and Virtual Sensor Model. Images of the monitoring stations are below:
All the trials have been carried out with promising results. Useful conclusions have been drawn from the results and will serve as the basis for a second set of experiments to be carried out by the end of the project, as well as support the definition of the requirements for Release 2 of the sensors and software components.
