A “GO” for Water Factory

Gepubliceerd op 31 januari 2019

Vallei en Veluwe gives agreement for the Life Water Factory in Wilp. The new water plant to be built will become an "all-in-one treatment" and will eventually replace part of the sewage treatment plant in Terwolde. In addition to producing clean water, the water plant extracts raw materials so that they can be reused. In this way the water board is building on its ambition to be circular in 2050. At the end of last year, the general board approved the plan for the new water plant in Wilp (municipality of Voorst).

Working circularly in 2050

With the water factory, Vallei en Veluwe is taking an important step to be fully circular in 2050. This includes separate collection and processing of sewage and rain water, so that the rain water no longer has to go through the purification system. Part of the purified water from the water factory is used to supply the Twellos stream with water, so that this stream again contains sufficient water of good quality. The new water plant extracts no less than 75% more nitrogen and phosphate from the polluted water than a regular purification plant. The aim is also to remove 80% of the drug residues, to keep 90% less sludge and to use 90% fewer chemicals.

Pilot project and collaboration

In this project, Vallei en Veluwe cooperates with the municipality of Voorst, the Province of Gelderland and the Ministry of Infrastructure and Water Management. Collaboration also takes place with the companies Attero and Schoneveld Breeding and the knowledge partners Aquaminerals, STOWA and Wageningen University & Research (WUR). Witteveen + Bos and Royal HaskoningDHV, as a construction team, will first carry out a pilot with Vallei en Veluwe to test whether the innovative idea is practically feasible. They will also start working on the further design of the installations. In addition, a suitable location is being sought on and near the Schoneveld Breeding and Attero companies on the Sluinerweg in Wilp.

Het is een uniek concept, aldus heemraad Bert van Vreeswijk. Als Waterschap Vallei en Veluwe hebben we samen met Witteveen+Bos het afgelopen jaar gekeken naar kansen en verbeteringen van dit nieuwe zuiveringsconcept. Ik ben blij met de uitkomst van een ‘alles in één’ waterfabriek die circulair werkt.
