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.
Our project
The Rivierenland regional water authority has decided to centralize the treatment of waste water in the Land of Heusden and Altena. The waste water previously treated in the three sewage treatment plants in the southern part will now all be treated at 1 central WWTP in Sleeuwijk.
Before that happened, the sewage treatment system in Sleeuwijk had to be renovated and expanded in terms of capacity. This was necessary because the treatment plants in Wijk and Aalburg, Eethen and Dussen were eventually decommissioned. Waste water from those places was transported directly to Sleeuwijk from then on.
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 was created.
In the area waste water was 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 had to be constructed, and the WWTP had to be extended and renovated.
The work was carried out by the consortium Van der Ven – Pannekoek GWW, in which Van der Ven was building the pumping stations and pressure pipes, and Pannekoek GWW was building the treatment plant. RWB took care of the mechanical work of the RWZI Sleeuwijk.
What is realized?
- Request for development of the preliminary design
- Grating system, sand catcher, bulkhead pre-set tank with cover
- Mixers, propellers, blower aeration system
- Recirculation pumps, reamer systems, re-sedimentation tanks
- Various (sludge) pumps, various mixers, gravity thickeners, belt thickeners
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 is centralized.
Centralization of WWTP Sleeuwijk has led to concrete results in the area of economies of scale. Due to economies of scale, there is relatively less maintenance and more effective treatment, resulting in cost savings. The increased capacity has also led to the construction of an energy plant.
