Our projects

Sweden Water Research conducts research into water and develops new, effective solutions to meet the future challenges facing the water services industry.

We create, run, participate in and initiate projects that seek out suitable partnerships, with the ultimate aim of increasing knowledge of successful methods for the development and climate change adaptation of the cities of the future. Projects within Sweden Water Research are run in close collaboration with the owner municipalities and will, in either the short or the long term, benefit day-to-day operations.

The conventional municipal wastewater systems recover only a small part of the plant nutrients found in the wastewater to farmland. The purpose of the project is to gather important stakeholders in the flow of nutrients from the households to farmland to assess the potential and, hopefully, further develop a urine separation system that has been developed by SLU.

BONUS CLEANWATER was a research project working with solutions to reduce microplastics and micropollutans in the Baltic Sea. The project focused on innovative research on water technology to remove micropollutants and microplastic from wastewater. The solutions were developed in close collaboration with end-users.

URINITE – Stabilisation of urine by nitrification

The urine separation systems of the future will include volume reduction to further decrease transport and storage needs and to obtain a more concentrated fertiliser. Stabilisation of the urine is required to not lose the nitrogen through ammonia volatilization during the volume reduction treatment. Nitrification is a promising method for stabilising urine.


The maintenance approach with underground pipes is often reactive and intervention takes often place after the pipe has failed. In the Pipestatus project we will develop methods for condition assessment for pipe inspections to help the pipe owners to be able to increase intervention before a pipe failure. None of the methods require interruption of supply or excavations. Non-dig methods and technical solutions are highly attractive for players both in Sweden and internationally. New solutions have therefore great market potential.

Back to the basics: high-loaded activated sludge

Degradation of organic substances in municipal wastewater is conventionally performed in the activated sludge process in presence of enhanced nitrogen removal processes. In the future, new nitrogen removal processes could demand a wastewater already treated for organics. The project "Back to the basics: high-loaded activated sludge" aims to make the high-loaded activated sludge process more efficient.

Membrane against brownification – ”GenoMembran”

Northern lakes and rivers have become browner and browner. Explanations to this brownification are a few, but they can be summarized as the influence from humans – both an increase of some and a decrease of others.


Emissions of the very potent greenhouse gas nitrous oxide contribute often very much to the sum of greenhouse gas emissions from wastewater treatment with enhanced biological nitrogen removal. The Danish project LaGas aims to identify, implement and validate new control strategies to mitigate nitrous oxide emissions in wastewater treatment.

Blue-green stormwater solutions

Open (blue-green) stormwater solutions get more common and are about to play a central role in the management of stormwater in Sweden and other countries in the world. However, there is a need for evaluation of existing systems and to find out what role the system plays in the overall management of the city's water. It is also considered to examine the importance of systems with regard to the quantity and quality of the stormwater that reaches the recipient.

Adaptive urban landscape

The project aims to collect and analyze different types of urban landscapes which are capable to adapt to climate change. The project concentrates on urban landscape and the opportunities it offers to cities in overcoming the water challenges. The focus is gaining more knowledge on design based techniques to make the cities more sustainable and resilient towards climate changes and the consequences.

The Warm and Clean City

Wastewater treatment is an important function of society, and one that confronts many challenges. The project, “The Warm and Clean City” is developing and testing new total solutions for the world’s wastewater treatment plants. The solutions are resource-efficient and facilitate utilizing substances in the wastewater for generating saleable products, while at the same time closing the water and nutrient loops.
