Wastewater

Taking measures to safeguard public health is getting more important. Witteveen+Bos works on improving the chemical and ecological surface water quality and closing water and raw materials chains to create a basis for a circular economy. We do this in newbuild projects, in refurbishments and capacity upgrades of existing treatment plants for both water authorities and industrial clients. To that end, we employ tried-and-tested concepts as well as new technologies, developed by us or combined with third-party solutions as a systems integrator.

We possess extensive knowledge and have over 40 years of experience in biological wastewater and sludge treatment as well as wastewater purification, in particular the extensive removal of nutrients and drug residues and other micropollutants to enable reuse or improve surface water quality. We also work on efficient sludge treatment and raw materials and energy reclamation from wastewater, sewage sludge and other biomass. Our expertise also includes energy, chemicals and costs, and minimising waste materials and greenhouse gas emissions during the construction and operational phases in the lifecycle of wastewater treatment plants.

Our work in the wastewater field spans the entire spectrum of transport and treatment systems, from the study phase through to the implementation and operational phases. We do this on both large-scale and small-scale facilities, and both in the Netherlands and around the world. We provide:

  • Strategic consultancy and feasibility studies
  • Systems integration, design and construction supervision of wastewater treatment infrastructure
  • Coordination of tender process and contract negotiation
  • Applied research and development of new technologies
  • Training, troubleshooting, optimisation and hands-on operational support
