Department Urban Water Management

Projects

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

Systems Engineering  (Tove Larsen, Max Maurer, Joao Leitao) looks at the engineering options and methodologies to lead the urban water infrastructures 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 study options on the minimization of impact on the environment, on the other hand it also offers unique opportunities to learn about changes of society’s lifestyle and also to develop early warning systems.

Intelligent Network Operations (Jörg Rieckermann, Joao Leitao, Andreas Scheidegger, Frank Blumensaat) aims at (i) developing methods to obtain better 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 of our 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 a urban water catchment.

Projects Systems Engineering

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.

Water and sanitation innovations for non-grid solutions (Wings)

The population has a high willingness to pay for reducing risks of wastewater flooding or combined sewer overflows

Valuing Adaptation to Climate Change Risks in the Water Sector

Urban Water Infrastructure Model (UWIM)

How can the overall performance of distributed treatment systems be estimated and maintained?

Model-based monitoring and management of distributed treatment systems (DSyM)

The costs of uncertainty

Network condition simulator for benchmarking sewer deterioration models

Network Condition Simulator

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

GRASP - Generation and Assessment of Sanitation Systems

Managing Uncertainty in the Design of Urban Water Infrastructure

Design of urban water infrastructure

Project aim is participative decision support for the long-term transition to innovative wastewater infrastructures.

Decision-making for wastewater infrastructure transitions

We aim at facilitating the use of Multi-Criteria Decision Analysis in urban water management practice.

Value-focused wastewater infrastructure planning

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

Physical disintegration of faeces in sewers

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