Remove I/I where it makes sense
We believe that Inflow and Infiltration (I/I) should be removed where it makes sense. Therefore, we have developed a tool, InflowGo, that reveals where capacity problems are best solved by removing I/I. The tool also shows where the savings achieved by reducing I&I are greater than the costs of removal.
Always up-to-date analyses at hand
Boundary conditions change quickly and wastewater systems need to keep up. Whether you are faced with new urban development, new environmental regulations, new political winds or new climate change predictions, InflowGo helps you stay on top. The economic and service-related consequences of changes become apparent through intuitive graphics.
Infographics for shared insight
Dynamic infographics makes it easy to see where and why I/I should or should not be removed. The intuitive illustrations improve the dialog between stakeholders.
Be the expert of your wastewater systems
As municipality or utility, you are the expert of your own wastewater systems. Retain and strengthen this expertise within your own teams: let InflowGo do the routine work and get more time to explore the solutions of the future.
The right perspective for the issue
The issue at hand determines the relevant perspective. Issues may relate to delivering the required level of service, reducing environmental pollution, minimizing investment costs, maximizing asset lifetime or reducing energy consumption.
Follow impacts and meet your goals
Are things moving in the right direction? When have we reached our targets? The continuous analysis of operational data makes it easy to follow-up on the impact of individual efforts. The desired goals are converted to KPI's in InflowGo so its easy to see when goals are met. Experience from both your own and others' efforts are used in InflowGo to improve both impact forecasts and suggested actions.
Browse between past, present and future
InflowGo is made to understand the present with the aim of exploring and planning the future. In this context, one often needs to go back in time to past analyses or even to a specific event. With InflowGo you have got the past, the present and the future at your fingertips.

Technology from your digital future
Inflow and infiltration in the cloud
InflowGo is a cloud service designed to help wastewater utilities incorporate inflow and infiltration in their continuous planning. InflowGo continuously receives existing data from flow meters and pumping stastions in the sewer network. Users see the analysis reports in their web-browser.
You configure and you modify
InflowGo is user configured and user maintained. It is easy to configure sub-catchment stations, add new stations or modify existing stations when new measurements come available or when equipment has changed. Should you need it, WaterZerv's support is always available and included in your subscription.
Data Analytics at its Best
InflowGo builds on a combination of the most recent research in the fields of flow data analysis, urban hydrology and hydraulics, pattern recognition, rainfall-runoff modelling, parameter estimation, optimization routines, data assimilation and parallel computing. And your data is spiced up with data from global and local climate and weather models.
InflowGo's browser based user interface is tailored to give you insight into inflow and infiltration. You can also seamlessly integrate InflowGo analysis results into your existing GIS tools through InflowGo's standard WMS server. InflowGo also provides a REST API for a tighter integration with your existing asset management or CCTV tools.

Water research going to waste.
At WaterZerv we believe that only a fraction of scientific, mathematical and engineering research within the field of urban water management is exploited to its full potential.
Putting water research to work.
Our ambition is to mobilize these large pools of knowledge to create real value in the world of urban water.
InflowGo is our first. More will follow.
With utilities, researchers and partners alike.
