Blauwe Ader: Hasseltstraat - Midden Brabantweg

Project description

This pipeline transports (rain) water from the centre to the border of the city. During the first 15 years after completion, both rainwater and first flush wastewater will be collected in the pipeline, which will be pumped out by a pump station to a Wastewater Treatment Plant (WWTP). After 15 years, the Blauwe Ader will act as a discharge pipe for rainwater which will be discharged in a waterpark. Only the first flush wastewater will still be pumped to the WWTP.
