Water sludge transport

Primary challenge owner: Waterschap Noorderzijlvest 

Secondary challenge owner(s): None



Water board Noorderzijlvest is responsible for maintaining sufficient, safe and clean surface water, which differs from the work of water companies, who only provide drinking water. One of the main tasks of our organization is to clean wastewater from our surface area. We do this at 13 wastewater treatment plants (WWTPs), where waste water sludge is produced. This sludge is transported by truck to a central location, where it’s processed. However, the transported sludge is only 3% dry matter and 97% water. We would like to reduce the amount of transport needed, for example by reducing the production of sludge, reducing the amount of water before transport or provide a tool for determining the best routes -based on buffer levels/location/traffic, for example. The reduction of transport reduces our environmental impact, with an added financial benefit.


The question/challenge for startups

Reduce the environmental and financial impact of the transport of wastewater sludge. 



  • In the case of developing a software tool for transport, we would like to make a scan on before hand of the possible yield;
  • Most communication in our organisation is in Dutch, English is however possible.
