Aqua Robur Technologies was by April 2017 rewarded a runner up from Vinnova, the Swedish Innovation Agency, for the soft funding programme “SME Instruments”, phase 1. The project “Self-powering flow indicator for leakage management in public water pipelines” was successfully performed during Q2-Q3 2017.


The company will during early 2018 apply for the next phase of the programme.


Abstract of project, phase 1: 

Between 25 and 50% of fresh water is lost in European pipelines, costing billions of Euros every year. Moreover, the possibility of contaminated water running from  taps is a serious concern. Water utilities are investing billions of Euros in installing water meters and sensors that allow them to detect leakages and to monitor water quality more precisely and in real time. However, these devices must be connected to a power supply, either the grid or batteries. This increases installation and maintenance costs considerably, while also limiting where the sensors can be deployed to accessible areas.


Consequently, it is impossible for water utilities to deploy an optimum number of sensors, thereby reducing considerably the potential of smart water management. The energy harvester is a small hydro turbine, which converts a small part of the water flow into electricity, which then can be used to power the Fenix Hub and on-site sensors. Additionally energy is sent to the intelligent energy storage, which guarantees energy supply to the sensors, even when water is not flowing. Water data are then sent to water utilities that can easily monitor water flow and quality in real time, thereby quickly identifying the location of leakages. The technology is easily installed in the pipeline and does not require maintenance works.
