Timely replacing aging ...

Timely replacing aging infrastructure would save much money and limit business interruptions. In the Netherlands the problem of aging sewage system is also a current issue in major cities. One example is Nijmegen, where the city council realized replacing the structures simultaneously would be impossible and deliberated with citizens in the different areas on how to go about the time schedule of replacing the old structures. An important problem in Nijmegen is how to manage archaeological findings when performing engineering work underground, as the city was originally founded by Romans and many remains of 2000 years old can still be found. The issues of how to prioritize between timely replacement, not interrupting local businesses, and treating historical artifacts are discussed between several stakeholders before commencing the actual work, in different phases. This is combined with informing residents about the possibilities of decoupling the rainwater they collected from their roofs or gardens from the sewer and saving it for water use; as well as new asphalt and street lights.
