Partnership for local management of rain water

A partnership was established, in April 2011, between the Danish Ministry of the Environment (the Nature Agency and the Environment Protection Agency) and Haveselskabet. The first step was creating a platform between research institutions, companies, governments, municipalities, landscapers, sewer masters, garden centres, garden owners, etc. with the aim of developing tools for municipalities and others that can be used when they want citizens in an area to decouple rainwater from the municipal sewage systems. The partnership completed its work in spring 2012.

The Danish Technological Institute (DTI), functioned as the secretariat and facilitator of the partnership.

Initially, the Partnership has identified barriers for citizens to decouple rainwater from the sewage systems, through meetings and workshops. Based on this, a series of workshops has focused on how to address these barriers and suggest possible solutions.

The barriers that has been examined in relation to local management of rainwater are e.g.:
• Legislation and administration
• Technological solutions
• Organization of citizens and authorities
• Citizen behaviour

The project was implemented as a partnership with grants from the Action Plan for eco-efficient technology, with a total of DKK 500,000.

Background on the co-operation for local management of rainwater
Heavy rains and resulting floods have highlighted the need to cope with large volumes of surface water and thus pressure on sewer systems. Last seen with floods among other Greve and in northern Copenhagen.
Environment Minister has indicated that rainwater should be seen as a resource that not only should be sent to sewer. Many municipalities also have a desire to promote the decoupling of rainwater from the sewer in residential areas where sewer capacity is too small. But there are no or few examples of how a municipality can successfully help that to happen in areas where the municipality wishes.

Steering committee
The steering committee consisted of Haveselskabet and the Ministry of the Environment (the Nature Agency and the Environment Protection Agency).

Environmental technologies

Any technology, that either directly or indirectly improves the environment. It includes technologies for limiting pollution with the held of cleaning, more environmentally friendly products and production processes, more efficient energy and ressource management as well as technological systems that reduce the environmental impact.

Examples include e.g. technology flue gas cleaning, wind turbines, water treatment, enzymes for animal feed and washing powder, biofuel production, energy-efficient pumps and substitution of chemicals with more environmentally friendly solutions.
