Water management involves much more than building dykes and windmills. The work also entails water level management, water quality management, adapting to climate change, dredging, and wastewater treatment. These projects are open for visits from international delegations.

Verdygo is a new standard in wastewater treatment. An important feature of Verdygo is its modular industrial construction, which allows a sewage treatment plant to expand or contract quickly and easily to respond to, for example, population ageing or growth.
Verdygo also helps the reuse of effluent at local level, for example in industry or greenhouses, thus making a considerable contribution to sustainable water treatment.

In 1953, the Netherlands was shocked by major floods. More than 1.500 people lost their lives during this disaster. To prevent that happening again, the Dutch authorities took major measures, of which the Delta Works are the most well known.
Recently, regional water authority ‘Brabantse Delta’ opened the Volkerak Zoommeer water storage area. With a capacity of 200 million cubic metres, this is the largest water storage area in the Netherlands. This capacity may be needed during a storm in combination with high water levels on the major rivers.

In the Pure Water Factory in Emmen, sewage is transformed into ultrapure water. Ultrapure water is so pure that it does not even contain minerals and calcium. With the smallest amount of chemicals, raw sewage is processed into this ultraclean form of water.
Scarcity of groundwater is one of the issues for which Dutch Water Authorities is trying to find a sustainable solution. With this factory, it hopes to take a firm step towards keeping water available and affordable for the local inhabitants.

Several sewage treatment plants operated by the Dutch regional water authority De Dommel discharge water into small streams with high ecological value. Purified sewage is more or less ‘dead’ water, and discharging it into these streams is not beneficial for the environment.
The water authority therefore aerates the water and passes it through several ponds before it reaches the surface water in the streams. In this way, the water collects more nutrients and organic material, so that it will not harm the ecology of the area.

Fresh water is becoming increasingly scarce. On the island of Texel, Dutch Water Authorities and its partners are exploring the possibilities of growing crops on salty ground. Researchers are testing the salt tolerance of crops like potatoes, carrots, and strawberries in an ultramodern open air laboratory.
They want to show that it is possible to grow crops on land that has been contaminated by salt.

Due to the consequences of climate change, the city of Rotterdam has to deal with higher levels of rainfall. Rotterdam is a crowded city with little space to store excess water. To relieve the pressure on the sewer system, ‘water squares’ are being created within the city.
One of these is the Benthemplein in the north of Rotterdam. When it rains heavily, the water is collected in special tanks in the square. Once it is dry, the water is discharged again.

Strong dikes are of vital importance for the Netherlands. This certainly applies to the area around the major rivers, where 4 million people live and work. The regional water authorities assure that these dikes stay in top condition.
Currently, the regional water authority ‘waterschap Rivierenland’ is conducting a large number of dike improvement projects in its area. As a result of climate change, the rivers have to store more water. Some dikes cannot deal with the expected increase in the quantity of river water. To reinforce the dikes, Rivierenland uses innovative techniques, such as geotextiles and dike dowels.

Live dikes are dikes equipped with sensor systems. A good example is the ‘LiveDijk’ in Groningen. The sensor systems measure the current strength of the dikes and predict their strength in the future. In this way, the sensor system contributes to better control and maintenance of the dike.
