Future City Flow | Webinar Series

Fall 2022

Learn how Future City Flow, a decision-support system for integrated stormwater management, can help optimise wastewater system control strategies to reduce overflows and get the highest return on investment.

High flows and infiltration/inflow in both combined and separate sewer networks is a rising concern.

To ensure an ample supply of safe water, comply with environmental legislation and save costs, water utilities and operators need a more efficient way to manage wastewater inflow.

Meet Future City Flow, a subscription-based cloud service that provides access to real-time simulation software and scenario-based planning tools to help buffer weather impact, population growth, resulting densification and aging infrastructure. Accessible from anywhere, Future City Flow allows users to identify potential improvements in existing wastewater systems within a set budget and timeline, effectively targeting I&I reduction.

Want to learn more? Join our upcoming four-part webinar series to see how Future City Flow optimises wastewater system control strategies and daily operations to reduce overflows and get the highest return on investment.

Episode 1: Inflow and Infiltration

Recording available below

In this first episode of our four-webinar series about inflow and infiltration (I&I) and Future City Flow (FCF), we will describe key performance indicators (KPIs) and methodology for efficient and strategic inflow and infiltration measures.

More specifically, we will investigate:

    • The different sources of inflow and infiltration
    • Weather independent KPIs
    • Our methodology in Future City Flow

Understanding the relationship between the problem you are having and the source of Inflow and Infiltration that causes your problem are crucial.

With a methodical approach to set targets, planning, investigation and follow-up, a good cost-effectiveness on what measures to apply now, and in the future, can be achieved despite a complex and often extensive problem.

DHI has extensive experience of inflow and infiltration studies and has in recent years developed principles and tools for methodically calculating, analyzing, and comparing inflow and infiltration with the Future City Flow solution.

This episode will touch upon the principles of Future City Flow. The following three episodes, will provide a more detailed walk through of the three different modules:

    • FCF Data
    • FCF Real-time control
    • FCF Planning


Dr. Lars-Göran Gustafsson

Dr. Lars-Göran Gustafsson is DHI Sweden AB’s Managing Director and holds 35 years’ experience in the collection system sector in addition to  modeling a variety of water environments. This includes interaction between hydro geology, infra structures and surface water.

He carries a PhD in urban hydrology with focus on analyzing and modelling inflow and infiltration. Dr. Gustafsson has also participated in a long list of RDI initiatives over the last 30 years.

Today he is responsible for digital solution developments within the Water in Cities business area, where Future City Flow plays a key role.

Episode 2: Insights and data analysis (FCF Data)

Recording available below

In this second episode of our four-webinar series about inflow and infiltration (I&I) and Future City Flow (FCF), we will dive into the FCF Data module. The data module focuses on analysing, visualising and reporting on data from sensors and gauges.

FCF Data provides the opportunity to perform advanced analysis on time series flow and rain data, as well as automated overflow reporting. Understand your historical data, receive target-based performance evaluations, get insights into the causes of your Inflow and Infiltration problems and report on overflows and rain events.


Dr. Peter Dimberg

Dr. Peter Dimberg holds a MSc degree in Aquatic and Environmental Engineering as well as a PhD degree in Earth Science with specialization in Environmental Analysis.

Peter has experience working within water supply and sewer networks since 2015 and joined DHI in December 2021.

His professional interests include analysing data, build models, GIS-analysis, and understanding the general big picture from scarcity of data.

Episode 3: Real time control (FCF RTC)

Recording available below

In this third episode of our four-webinar series about inflow and infiltration (I&I) and Future City Flow (FCF), we will dive into the FCF RTC module. The RTC module focuses on providing a status on your infrastructure here and now as well as expected future load.
At the core of the module is a weather forecast that is updated as often as the meteorological source allows. When connected to real-time sensors/gauges and/or a supervisory system, the system looks at:
    • State variables and current conditions – measured flows and levels
    • Calculated flows and levels in the catchment
    • Current and calculated CSO volumes
    • Water volumes in the network and basins, both hindcast and forecast
    • The estimated run-off from each subcatchment area for each flow component, i.e. inflow, infiltration
What you can expect from utilising the RTC module:
    • Minimise the impact of flow variations in extreme weather
    • Improve water quality in receiving water bodies
    • Attenuate flows to the WRRF
    • Reduce CSO’s
    • Control where CSO’s occur to minimize environmental impact
    • Better utilise the flow attenuation capacity in the conveyance system


Dr. Maria Roldin

Dr. Maria Roldin holds a MSc degree in Environmental Engineering with specialization in Water Resources Management from Lund University in Sweden (2007), and a PhD degree in Water and Environmental Engineering from the Technical University of Denmark (2012).

She has been working as a consultant at DHI Sweden since 2012, and specializes in integrated water modeling, sustainable stormwater systems, and real time control and forecasting systems of sewer networks.

Episode 4: Strategic planning (FCF Planning)

Tuesday, 8 November, 2022

08:00 or 14:00 UTC

In this fourth and final episode of our four-webinar series about inflow and infiltration (I&I) and Future City Flow (FCF), we will dive into the FCF Planning module. The Planning module focuses on helping you plan your public budget by providing insights into what measures will have the biggest effect on your main problem.
Easily create and compare I&I reduction, cost efficiency and expected ROI on planned mitigation measures based on modelled and measured data.  You achieve this by being able to compare different catchments with respect to:
    • How they contribute to inflow and infiltration
    • Different KPIs depending on what problem the I&I is causing in your network
    • Which measures will generate the greatest impact at the lowest cost in a given catchment
Apart from providing a crucial understanding of the relationship between the problem you are having, the source of Inflow and Infiltration that causes your problem and what measures that most effectively mitigates those consequences, the planning module also has a very strong communications aspect. It allows people with domain knowledge to discuss budgets and effects with people not having wastewater domain knowledge.


Emelie Alenius

Emelie Alenius has worked with issues around Inflow and Infiltration for the last 10 years.

She has experience from many aspects and viewpoints of I&I, having worked with the topic in both in public and private companies, in large and small, combined, duplicate and mixed networks and with field surveys as well as strategic and long-term action portfolio planning.
