Centralization; from 4 to 1 sewage treatment plant
About Water Board Rivierenland
Water Board Rivierenland ensures safe dikes and a balanced water system. Various governments have drawn up rules for this. European (including the Water Framework Directive), national (including the National Administrative Agreement on Water) and regional (including water level decisions) regulations. Water Board Rivierenland applies these rules in its own policy.
The Rivierenland Water Board ensures good water quality. Clean water contributes to a good living environment for people, animals and plants. The waste water from villages and towns is treated and to ensure that the surface water is not polluted.
The Rivierenland regional water authority has decided to centralize the treatment of waste water in the Land van Heusden and Altena. The waste water that is now treated in the three wastewater treatment plants in the southern part will be treated in the future at 1 central WWTP in Sleeuwijk.
Before this happens, the sewage treatment system in Sleeuwijk must be renovated and expanded in terms of capacity. This is necessary because the treatment plants in Wijk and Aalburg, Eethen and Dussen will eventually be decommissioned. The waste water from these places is then transported directly to Sleeuwijk.
One of the requirements of this project was that the current treatment system must remain in operation at all times
After expansion, a treatment capacity equivalent to 64.000 inhabitants will be created.
In the area waste water is treated via three smaller wastewater treatment plants: the WWTP Dussen with a capacity of 9,500 p.e. and 360 m³/h; the WWTP Eethen with a capacity of 8,000 p.e. and 200 m³/h; the WWTP Wijk & Aalburg with a capacity of 13,000 p.e. and 480 m³/h.
In order to achieve the objective of the project, new pressure pipes and so-called transit pumping stations have to be constructed, and the WWTP has to be extended and renovated.
The work is being carried out by the consortium Van der Ven – Pannekoek GWW, in which Van der Ven is building the pumping stations and pressure pipes, and Pannekoek GWW is building the treatment plant. RWB is responsible for the mechanical work of the RWZI Sleeuwijk.
What is realized?
Our customer speaks
“The expansion and modernization of WWTP Sleeuwijk is necessary in order to be able to continue to work efficiently and to be able to meet all the legal requirements in the field of waste water treatment in the future. RWB takes care of the crucial mechanical work in this respect.”

“Scaling up and expansion of the installation in Sleeuwijk.”
In order to purify more efficient and sustainable waste water, the Rivierenland water board will centralize.
Centralization of WWTP Sleeuwijk leads to concrete results in the area of economies of scale. Due to economies of scale, there is relatively less maintenance and effects can be treated, resulting in cost savings. The increased capacity offers opportunities for an energy plant in the future.
