Dutch water supply company WML, serving the province of Limburg, has published its data driven approach for asset management in ‘Water matters’. WML intended to verify if the annual replacement ratio for the drinking water network of 1,25% per year was still optimal. A lower ratio would obviously save money, whereas a higher ratio would be likely to lead to less leakages and a lower non-revenue-water percentage. To calculate the optimum objectively and accountably, Spatial Insight’s Asset data Integrator (ADI) and the SI-Cluster was implemented and applied.
To minimise the total societal costs of the replacement of underground infrastructure, alignment of projects with the net managers of gas, electricity and sewers are crucial. WML used Spatial Insight’s SynergieNL to facilitate the cooperation with the external parties.
