Visualising corrosion and odour hotspots in municipal sewer networks before assets fail

  • Visualising corrosion and odour hotspots in municipal sewer networks before assets fail

About the entity

Envirosuite
Envirosuite is a trusted partner to major water utilities across the world. We build world-leading solutions that enable our customers to make responsible operational and development decisions with localised data and insights.

Sewer corrosion can severely limit the lifetime of assets and costs millions to repair. Assets can fail well before the expected life of the equipment and costly manual inspection methods can only cover a small fraction of the network each year.

The cost of replacement and maintenance for unexpected issues can be in the millions. Odour issues in the network can be highly disruptive and understanding and managing safety issues related to sulfide and methane generation is a critical issue to most water utilities.

SeweX identifies sewer corrosion issues before costly and disruptive incidents occur. Dynamic modelling of corrosion risk is translated to provide rapid analysis of the likely cause of corrosion risk that has occurred or is emerging. Alternative operating and control scenarios can then be simulated to identify the best approach for short-term response and long-term asset management at water utilities.

What is SeweX?

SeweX is based on an advanced mathematical model that describes the physical, chemical and biological processes in sewers.

SeweX has integrated complex models used to represent sulfide and methane generation in sewer networks into a solution that can be used by decision makers to:

  • Quickly and easily identify major cost savings in the design of a network.
  • Pinpoint the source of pollution events in real-time.
  • Make operational and design decisions to avoid corrosion, odour and safety issues.
  • Identify sewer corrosion and odour risk priority areas quickly and predict the outcome of different operating scenarios to solve those issues

Real-time management of corrosion, odour and safety risks in sewer networks

The cause of odour complaints in the network can be quickly identified with EVS SeweX, together with analysis of potential dosing approaches to minimize ongoing costs for managing the issue. Safety risk related to sulfide and methane generation is also easily understood with network-wide mapping of risk before sewer inspection.

Market alternatives offer only simple storage and display of monitoring information. SeweX provides rapid understanding of risk as it develops and supports science-based decision making for making the best short-term and long-term decisions for improvement.
