Projects - Eawag

The Urban Water Management department projects are organised according to four research areas:

Systems Engineering (Tove Larsen, Max Maurer, Joao Leitao) looks at the engineering options and methodologies to lead urban water infrastructure into a sustainable future.

Source typing and tracking (Christoph Ort, Jörg Rieckermann, Frank Blumensaat) The quantification of pollutant loads in wastewater is, on the one hand, a requirement to minimize impacts of pollutants to the environment, and, on the other hand, it also offers a unique opportunity to learn about human lifestyle changes and also to develop early warning systems.

Intelligent Network Operations (Jörg Rieckermann, Joao Leitao, Andreas Scheidegger, Frank Blumensaat) aims to (i) develop methods to improve data on key variables and states of our wastewater systems, such as, rainfall, flows, and pollutant discharges to receiving waters, (ii) provide better models to assess water and pollutant fluxes, as well as, urban flood risk and aging infrastructure.

Urban Water Observatory (Max Maurer, Frank Blumensaat, Andreas Scheidegger) is a test-bed where modern measurement equipment provides us with a detailed picture about the processes in an urban water catchment.

Goal is an improved planning procedure for sustainable water supply and wastewater infrastructure management that links into the existing Swiss governance structures.

Sustainable Water Infrastructure Planning (SWIP)

An inter- and transdisciplinary strategic research program that strives to develop novel non-gridconnected water and sani- tation systems that can function as comparable alternatives to network-based systems.

The aim of this project is to gain more insight about sustainable infrastructure management and to develop tools and methods for complex decision making for infrastructure planning.

Sustainable Network Infrastructure Planning (SNIP)

The aim is to develop systematic methods for the generation of locally appropriate sanitation system options and for the quantification of sustainability performance indicators

We are identifying the challenges of modular infrastructure systems for the Swiss economy and society using the example of urban water management.

COMIX: Challenges and Opportunities of Modular water Infrastructures

Decentralisation changes wastewater quantity and quality that is discharged to the sewer. We investigate the effects of these changes on the operation of existing centralised sewer systems.

Transition to decentralised wastewater treatment systems - its effects on the operation of sewers

We quantify the physical disintegration of faeces in sewers - a stochastic detrition model is developed and calibrated by flow reactor experiments using PIV and image analysis backlight illumination

The ‘Transitions Pathways Generator’ (TPG) model aims at the systematic generation of transition pathways describing technical adaptations of the urban drainage infrastructure.
