“An integrated solution for groundwater, rainwater, waste water, streams and ponds creates attractive housing in a new suburb (NyE), with room for exciting architecture. The water cycle plays a key role in urban development in Denmark, and water is one of the ever-present elements in our lives. Århus needs to prevent flooding caused by climate change, avoid polluting our groundwater, and improve the environment in streams and ponds to allow the use of water to create recreational value for the residents. This way, Århus can build a balanced aquatic environment, which will ultimately create a better city.” (Ref. 1) The establishment of the first stage consisting of 650 homes, day care center and grocery store was initiated in the autumn of 2016 after more than 10 years of planning, and in the summer of 2018, the first residents moved into Nye. More homes are on the way. (Ref 14). In its current form of just over 150 ha, it has a capacity of approx. 15,000-20,000 inhabitants or approx. 10,000 homes at full expansion (Ref 15)

Focus

Creation of new green areas, Maintenance and management of urban nature, Management of rivers and other blue areas, Ecological restoration of degraded ecosystems

Project objectives

The objectives of the intervention are to integrate solutions for groundwater, rainwater, wastewater, streams and ponds that create attractive housing. The aims are to prevent flooding caused by climate change, avoid pollution in the groundwater and improve the environment in streams and ponds, and to use the water for recreational values. Green and blue spaces (mostly connected to water) are included in the vision of Nye. A long-term goal is the development of a climate park that can be created in the form of a nature reservation with marshy areas, trees and bushes, in the undeveloped area west of Nye. The climate park will make it possible to tackle extreme rainfall caused by climate changes over the next few years, through a collection of rainwater and controlled flooding into the park. (Ref. 1, 5) A long-term goal is the development of a climate park that can be created in the form of a nature reservation with marshy areas, trees and bushes, in the undeveloped area west of Nye. (Ref 5)

Implementation activities

Using the integrated streams and ponds (which provide the possibility for architectural solutions) for outdoor activities. (Ref. 1) "Aarhus Water and the Tækker Group are working to think up better ways of using rainwater integrated into the development plan right from the start. The project group is currently looking beyond the boundaries of the city for ideas and working on a development plan that incorporates them." (Ref. 13) Also, NIRAS has developed an ambitious strategy for handling the water, which means to integrate rainwater as a recreational element, as well as to use water for toilet flushing. (Ref. 12) The finished city is seen as an independent city with shopping opportunities, schools, day care institutions, sports facilities, medical center, cafes, church, playgrounds, etc (Ref 15) The climate park will make it possible to tackle extreme rainfall caused by climate changes over the next few years, through collection of rainwater and controlled flooding into the park. (Ref. 1, 5); repurpose water: integrate rainwater as a recreational element, as well as to use water for toilet flushing. (Ref. 12)

Climate-focused activities

Climate change adaptation:

  • Restore wetlands and/or coastal ecosystems to dissipate the effects of flooding and/or storms
  • Implement sustainable urban drainage infrastructure (e.g. to make space for water)

Biodiversity conservation or restoration-focused activities

Biodiversity restoration:

  • Rehabilitate and restore damaged or destroyed ecosystems
  • Restore species (native, endangered, or unspecified)
  • Other

Main beneficiaries

  • Local government/Municipality
  • Private sector/Corporate/Company
  • Citizens or community groups

Governance

Management set-up

  • Co-governance with government and non-government actors

Type of initiating organisation

  • Private sector/corporate actor/company

Participatory approaches/ community involvement

  • Co-planning

Details on the roles of the organisations involved in the project

Property developer Tækker Group joined forces with the City Council and Aarhus Vand (Aarhus Water) to put together an integrated solution for water in the town. Furthermore, Nye sets new standards for how a private developer can join forces with the local authority, water utility and consultants to create the town of the future, by focusing on a cohesive approach, balance and sustainability. (Ref. 1)
