AquaClim – Triplicate (2023-2027)
AquaClim is a project financed by the Research council Formas and is led by Lund University, in cooperation with Luleå University of Technology, Uppsala University and Chalmers, as well as a number of water utilities and Swedish water and wastewater association “Svenskt Vatten”. The project runs for five years and finances five PhD candidates and a research school (Water Research School). The Water Research School gathers the PhD candidates who belong to the research clusters, partly financed by Svenskt Vatten. Today around 80 PhD candidates are part of the research school.
The overall aim of the research projects connected to AquaClim is to build transdisciplinary competences by today’s and the future experts to be able to transform the water sector and specifically work with questions related to climate change.
Triplicate is the subproject that is carried out at Luleå University of Technology, in cooperation with Lumire AB. I this project it is investigated in what contexts source separating sewage systems with three pipes (triplicate system) can be resource efficient in relation to material use, CO2 emissions and other environmental impacts. It will also be investigated from which economic perspectives it is profitable to produce fertilisers from the toilet fraction of the wastewater. Are there any other drivers for introducing triplicate systems, such as water scarcity, limitations in existing infrastructure or need for technical water? In new areas it is easier to install triplicate systems with greywater and black water in sperate pipes. But how would the transformation look like in existing areas. Is it legal and/or are economic measures needed to support this transformation? These questions will also be studied in the project. At Luleå University of Technology, researchers from the research subjects Urban Water Engineering, Building Construction Management and Building Technology as well as Economics are involved in the project.
