Stakeholders in and around Park Lingezegen play an active role at RichWaterWorld, meaning that the results can be applied on a regional scale and help to promote integrated area development. The work package 'Integrale gebiedsontwikkeling' ('Integrated regional development') is aimed at the integration of services and products that are related to activities of RichWaterWorld's partners, which aim to create a self-sufficient region in terms of water, energy, raw materials and food.
Park Lingezegen is a 1,700-hectare landscape park located between the Dutch cities of Arnhem and Nijmegen. 80% of the park has already been completed. It acts as a green lung for this urban region and revolves around recreational and environment-related activities as well as landscape development. To achieve this, the planners designed a basic configuration of facilities, with beautiful landscaping elements, cycle paths and cultural activities. Alongside this, a water storage location was installed in the 'Waterrijk' area of Park Lingezegen, which protects the city district of Arnhem-Zuid from flooding.
Water and energy landscape
The theme 'Water' combines water storage with a retention function, making it possible to retain surplus water due to extreme rainfall for use in dry periods. This is especially important for the horticultural and fruit-growing activities in 'de Kop van de Betuwe' area. As this water is also purified using biocascade technology, a clean water supply can be achieved and used for nature-related purposes, recreation and possibly also as a drinking water supply in the future. The plants which have been incorporated as eco-engineers in the purification process produce a great deal of biomass. The biomass can be utilised in various biobased industries for the production of new raw materials, biogas, green organic fertiliser and high-quality components from hormonal streams, for instance. This multifunctional approach for water-related tasks represents an initial practical example during the implementation of the Dutch Delta Programme.
The theme 'Energy' places Park Lingezegen in a regional context. For example, the neighbouring horticultural area of Bergerden is locally a considerable energy producer as well as user. Furthermore, the Dutch cities of Arnhem and Nijmegen have difficulty achieving their renewable energy ambitions within their municipalities without a contribution from the 'de Kop van de Betuwe' area.
Biomass from biocascade water purification at Park Lingezegen can produce biogas through fermentation. Growers at Bergerden can use this energy to heat their greenhouses and produce the CO2 that their plants need. This is sure to form a substantial energy source by combining this source of energy with biomass from elsewhere in the region. As a consequence of climate change, forecasters predict a sharp increase in the quantity of biomass in the water courses of the Dutch Water Authority Rivierenland.
The combination of Park Lingezegen and Bergerden horticultural area can also play an important role in the region's ambitions in terms of heat production. The municipalities of Arnhem and Nijmegen would like to connect their existing networks in the future in order to give rise to one united and robust 'heat' network. The desired connection between the networks of Nijmegen and Arnhem cuts through Park Lingezegen. By connecting the Bergerden horticultural area to this transport line, the heating requirements of this area can be met in a sustainable manner. Not only that, but the existing heat supplier to the growers can, in times of large demand, supply heat to other connected houses and companies. Finally, the 'heat' network can also be connected to local 'heat' networks, which will be primarily supplied from thermal energy storage systems. By harnessing their potential, the 'heat' network can also boost the local and regional economy.
