REWAISE

REWAISE was one of five innovation projects supported by the Horizon 2020 framework program. The goal was to reduce the use of drinking water and use water in a smarter and more efficient way.

The project was a collaboration between water companies from Spain, Great Britain and Sweden, where VA SYD led the Swedish part.

The collaboration consisted of 24 partners in 11 countries, divided into three geographically different areas, so-called hubs. In addition to 5 water and wastewater companies, the partnership also included 9 universities and research institutes and 8 small and medium-sized companies. The overall goal was to reduce the use of drinking water and use water in a smarter and more efficient way.

The purpose of the Swedish part of the project was to investigate how water-use can be improved with examples from the urban development processes in Sege Park in Malmö, and Brunnshög in Lund. We did this through new innovative solutions that focused on harvesting and reusing stormwater, local cycles with nutrients from urine-sorting toilets and digital methods.

Test and evaluation with test beds

REWAISE worked with testing and evaluating new methods within three principles. To know what works, new knowledge and technology needed to be realized in test beds on a smaller scale, before large-scale introduction. From theory to practical implementation.

Value in water can be extracted by locally recycling nutrients from toilets and reducing the consumption of drinking water.
Value from water can be created by using rainwater for different purposes and developing local water services and related products and services, e.g. local production of water for irrigation, fertilizers and cultivation that creates new jobs, directly or indirectly.
Value through water intended to lead to an improved living environment where health and well-being increase, while emissions, risks and vulnerability decrease.

Innovation & new business opportunities

REWAISE was also about creating business opportunities and market niches for new technologies and services. Because the utilities provided test beds, it was possible for innovation companies to get early feedback and support directly from the market. Small and medium-sized companies were involved in the work of, among others, WIN Water.

The Swedish consortium

The Swedish consortium is led by VA SYD with joint project management from Sweden Water Research.

Other partners in the project are

City of Malmö, Lund University, MKB, P-Malmö, WIN Water, Lund Municipality and SLU.
