MACRO is an innovation project that continued to receive support form Vinnova during the 2019. The project, which has been running since 2015, helped ensure that Stockholm Vatten och Avfall was commissioned in 2020 to develop and test a source-separated waste water system in Stockholm Royal Seaport.
"This project is extremely interesting and may lead to a paradigm shift in Stockholm's development of waste water systems," says Erik Karlsson, Director of Strategic Planning, Stockholm Vatten och Avfall.
By dividing wastewater streams into separate systems in residential properties, resources such as water, energy and plant nutrients can be managed more efficiently. One of the world's largest areas with a soure-separated waste water system is now planned for the last phases of Stockholm Royal Seaport. Two waste water sewers rather than one are planned in Värtahamnen and Loudden. The system will connect 6,000 apartments and 170,000 m2 of commercial space once the area is built.
The City of Stockholm is one of 10 partner organisations along with three municipalities, business, and academia. The budget for the third phase of MACRO is SEK 18.4 million and the project is expected to have considerable significance for the future of wastewater management in Stockholm.
