Water storage at former MOB complex in Odijk combats waterlogging and dehydration
A water storage facility has been created at the grounds of the former MOB complex in Odijk in order to combat waterlogging and dehydration. A rainwater sewer drains precipitation to a natural water storage area.
Water management at the grounds of the former MOB complex (comprising military buildings and the associated infrastructure) in Odijk will be structured in a sustainable and climate-adaptive manner. Clean rainwater flowing off the roofs and the grounds normally ends up in the sewer system to be discharged to a water purification plant. Under this project, rainwater is collected and discharged to a natural water storage area through a pipe system.
To achieve this, room is being created in the existing strip of greenery on the west side of the grounds. Here, a “tray” will be excavated to store the rainwater. To lead the collected water to this natural water storage area, a central pipe, a rainwater sewer, will be constructed over a distance of some 250 metres on two lots of the MOB complex. This sewer consists of a concrete tube with a 600 mm diameter, set approx. two metres beneath the surface.
The water storage area gradually returns the water to the natural environment, on the one hand through local infiltration into the soil and on the other, by gradually returning the water to the district water board’s water system. This water system is subsequently used to irrigate the various farmland and horticultural areas in the region, thus combating dehydration.
Lesson learned from the project
A complicating factor in this project was that the rainwater pipe is located on private property. Its construction and right in rem required extensive consultations with local businesses. In such cases, environmental management is the main success factor for a project.
