Siemens expands its digital portfolio for water, wastewater and waste management
SIWA Treatment Optimizer reduces energy consumption and emissions in wastewater treatment
New solutions for water, wastewater, and waste
SIWA Quality Inspector is a software module for data-driven water quality decision making. It analyzes water quality parameters in real time – from treatment all the way to the end consumer – and helps operators detect changes in the network early, such as water age, mixing effects in tanks, or quality deviations in distribution. In doing so, it provides the foundation for more proactive operating strategies and preventative maintenance.
For wastewater treatment,
Siemens has developed the SIWA Treatment Optimizer – a software solution based
on physics-based models that supports plant operators with real-time process
control. At its core, the solution uses mechanistic process models to analyze
the treatment process in real-time and deliver explicit control recommendations
for plant operation. Digital twin technology also enables the simulation of
design scenarios. All SIWA applications are part of the Siemens Xcelerator
portfolio.
Soft sensors further expand the data foundation: they continuously calculate process variables such as total suspended solids, biological oxygen demand, and nitrous oxide emissions — even where physical instrumentation is unavailable. This gives operators a deeper view of actual process performance and helps ensure compliance with regulatory limits, even under fluctuating influent conditions. Depending on the use case, energy cost savings of up to 25 percent are achievable.
Amrutha Venugopal, Head of the
Water and Waste business at Siemens said: “Water and wastewater operations are
often difficult to assess in real time, leading operators to rely on experience
or safety margins. Our digital solutions bring greater transparency to process
behavior. With SIWA applications, soft sensing and real-time water quality
monitoring, operators can make more precise decisions -for example on aeration
or chlorine dosing - reducing uncertainty as well as energy and chemical
consumption. These scalable solutions are built for the realities of today’s
plants and networks.”
Efficient material flow monitoring and plant operations in waste management
Siemens is expanding its
portfolio at IFAT 2026
to include waste management alongside its established water and wastewater
solutions. The enhanced portfolio covers the entire waste lifecycle – from
collection and sorting to treatment, recycling and energy recovery. To support
this, Siemens’ Totally Integrated Automation (TIA) portfolio enables efficient,
secure and integrated operation of recycling plants.
The portfolio is rounded out by two additional solutions from the
automation and communications space. Simatic WinCC Unified ResCon introduces a
fully integrated load management system into Siemens’ Simatic WinCC Unified
SCADA solutions: it automatically monitors and controls electricity, gas, and
other utilities, helps to prevent costly demand peaks, and delivers real-time
transparency into energy flows.
The CP1243-1 communications
processor enables flexible integration of distributed assets into a wide range
of industrial communication protocols as well as modern cloud and Internet of
Things (IoT) platforms. With built-in IPv6 support, web server and diagnostic
functions, and event-based alerting, it is designed to meet the demands of
modern, connected infrastructure environments.
Siemens at IFAT 2026 – Hall C1, booth 305
With its new solutions for
drinking water, wastewater and waste management, Siemens is bringing together
digital tools for three core areas of municipal and industrial environmental
infrastructure at IFAT 2026 – while also showcasing its full automation and
digitalization portfolio for the water sector. At the center of the exhibit is
the integrated control center: it gives operators a unified, transparent view
of all their assets and facilities. It consolidates data from a wide range of
subsystems into a single platform, regardless of the infrastructure domain.
Open interfaces and a scalable architecture create the foundation for
data-driven operations, predictive maintenance, and advanced digital services.
Siemens will also demonstrate how the integrated
control center can be combined with additional digital tools: AI-based
solutions for leak detection, process modeling and simulation for wastewater
treatment, and modern energy management systems that provide transparency into
resource flows and help reduce emissions and operating costs. Cybersecurity is
another key focus: Siemens supports operators of critical water infrastructure
in protecting their assets and meeting regulatory requirements.
