The ‘Waterwinst’ (water gain) website presents building blocks for and examples of function combinations of drinking water extraction and other land use: nature, agriculture, urban area, recreation, water storage and more. This information helps and inspires people looking for possibilities to work together within the soil and water system in order to combine the various functions the landscape offers as optimally as possible. KWR created the website by order of the Dutch water companies to illustrate how collaboration between different regional partners can lead to wonderful results, give them the opportunity to share knowledge and gain greater insight into each other’s interests and motives.
Water companies supply us with drinking water obtained from ground and surface water in areas that many other parties use as well. Water extraction sites, as well as functions such as agriculture and nature, are usually highly location-specific and all have their own demands on the (ground) water system. And these don’t always coincide. Together with partners, the Dutch drinking water companies made an inventory of the function combinations that already exist and what benefits they have provided in terms of usage functions. Many great initiatives have been realised in recent years, but the inventory also shows that there is room for improvement and that there are often different options for realising successful function combinations. This knowledge is summarised on the Waterwinst web page, using fifteen examples we have worked out. We hope that the Internet page will also inspire other function combinations in which collaboration and smart use of the water supply are important.
What is water gain?
It is the ambition of the water companies to sustainably incorporate their extraction efforts in the environment that they have a strong connection with. But how do you ensure that in the increasingly populated Netherlands the water extraction combines well with the other functions? Or, even better: how do you ensure that the functions enhance each other, creating water gain?
This question is approached based on the water systems in the different Dutch landscape types. Where are the user functions in the water system, how do they influence each other and what solutions are there? Such solutions may be technical measures to improve existing situations, but also a new combination of functions, developed in an area-based process. It is important that the parties involved understand each other’s motives and interests and respect them. To promote the understanding between the sectors, the interests and motives are also summarised on the website. In the description of the existing examples we look at the preferences, measures and (success) factors for realisation.
What can you find on the web page?
On the web page we present building blocks for and examples of function combinations of drinking water extraction and other land use: nature, agriculture, urban area, recreation, water storage and more. This information is intended to help and inspire people looking for possibilities to work together in order to combine the various functions as optimally as possible. A section is also dedicated to the different landscape types in the Netherlands and the opportunities they offer for function combinations. Lines of thought have been worked out for the sandy soil areas and lateral moraine areas that can be used in future area-based processes.
Where do we go from here?
The web page is now online! We look forward to filling the website with new knowledge and inspiring examples over the coming years. They don’t all need to be function combinations with water extraction, other examples in which ground or surface water plays a role can also contain building blocks that provide a solution in other situations. But even more, we hope that the examples and background knowledge invite area managers, experts and policy officers to approach the subject of function combination differently and get together sooner to look for water gain situations.
