Creaternity Impact Moments: Circular Sanitation Systems

How can sanitation systems be designed to support circular and sustainable resource use?

On 2 February 2026 at 15:00 – 16:00 Creaternity invites you to a digital seminar where Inga Herrmann (Luleå University of Technology, Stormwater&Sewers) will share insights from current research and practice on circular solutions for small-scale sanitation systems. The seminar is part of the Creaternity’s Impact Moments series.

No.33 From silos to collaboration – the stormwater management of the future

17 February 2026, 10:00-11:00

How do we prepare our cities for cloudbursts and climate change?

The SODA project has, over four years, brought together 26 actors from different organizations to develop new working methods, technical solutions, and training programs that strengthen sustainable management of stormwater and cloudbursts on local plots. To break down organizational silos and raise the level of knowledge, the project has produced checklists, climate calculations, collaboration guides, training programs, and even introduced a new professional role – all aimed at creating robust, green, and pleasant environments. The results live on in handbooks, standards, and new collaborations that make Swedish municipalities better prepared for the future.

No.34 Graph theory applications in Urban Drainage Networks: Practical Insights from an Illustrative Case

17 March 2026, 10:00-11:00

Urban drainage systems can be represented as graphs, where manholes and junctions are nodes and pipes are edges. This allows the use of graph-theoretical tools to interrogate networks with very practical questions: Which pipes are structurally critical for the network, and where should inspection, maintenance and renewal be focused to reduce risk most effectively?

In this presentation, Emmanuel Okwori from Luleå University of Technology introduces key graph concepts for urban drainage in accessible terms and shows how they can be combined with data that utilities already have, such as CCTV inspections, blockage history and basic hydraulic indicators. Using an illustrative case from real sewer sub-networks, he demonstrates how edge-based centrality measures and simple spatial analysis can highlight “critical” pipes that are both important for connectivity and vulnerable in practice.

He also briefly points to other promising applications of graph theory for utilities – for example sensor placement, tracing pollution or flood pathways, and coordinating renewal across multiple networks – to show the broader potential of these methods for asset management.

No.35 Doing more with fewer sensors; prioritizing stormwater measurement locations

14 april 2026, 10:00-11:00

In this seminar, Emmanuel Bangura, PhD student at Luleå University of Technology, will present his research focused on balancing monitoring efforts and data needs for urban stormwater models. He will highlight practical guidelines for strategically deploying flow and level sensors to obtain data for reliable model calibration, along with key lessons learned in the field. Results from a study examining urban drainage behaviour across nested sub-catchments will also be discussed.

No.36 Treatment Performance and Micropollutant Removal in Decentralized and Centralized Wastewater Treatment Plants in Luleå municipality

26 May 2026, 10:00-11:00

In this seminar, Rayssa Jacob, visiting researcher in environmental engineering from Rio de Janeiro State University – Brazil, will present insights from a comparative evaluation of decentralized and centralized wastewater treatment plants operating under subarctic climatic conditions in the municipality of Luleå as part of the ArcticSewlutions Project. The presentation will discuss how wastewater treatment plant scale, technology type, and cold-region conditions affect overall treatment performance, including general trends related to micropollutant removal.

Water and sanitation seminar and industry day at Luleå University of Technology

🕘 24 February 2026, 13:00-17:00

🏠 A117 Luleå University of Technology

On February 24, 2026, it is time for the annual Urban Water Engineering seminar at LTU. This year's theme is Stormwater. The seminar and industry day are arranged in collaboration with the water and sanitation cluster StormwaterSewers at LTU and the national organization Swedish Water. The seminar takes place from 1:00 PM to 5:00 PM. During the coffee break, there is an opportunity to talk and mingle with companies and municipalities outside room A117 (LKAB-hall).

The water and sanitation seminar is arranged for students taking the course Water and sanitation systems in the master's programs Natural Resources Engineering, Väg- och Vattenbyggnad and Civil Engineering Engineering as well as the two-year program Civil Engineering. The seminar is also open to other interested students and professionals in the industry (free of charge, but registration is required).

After the seminar, the evening continues with a dinner buffet for students, industry professionals and employees at Urban Water Engineering, LTU.

The program and registration link will be published in January.
