What Is Sewer Thermal Technology?

David Valentine, STEN Director • October 10, 2024

Sewer Thermal Technology Explained in Non-Academic Terms

In short, sewer thermal technology is like turning a source of waste heat into something useful and environmentally friendly, making our energy systems more efficient and sustainable.


What It Is

  • Sewer thermal technology uses the heat that's already present in our sewer systems to help heat or cool buildings. Think of it like harnessing the warmth from the pipes below our streets.


How It Works

  • Heat Source:  Sewers carry wastewater, which is often warmer than the surrounding ground. This warmth comes from things like hot showers or industrial processes.
  • Energy Extraction:  Special systems can capture this heat from the sewers and use it to warm up buildings.


Why It’s Good

  • Eco-Friendly:  It’s a sustainable way to use energy that’s already being produced, which helps reduce our reliance on fossil fuels and cuts greenhouse gas emissions.
  • Cost-Effective:  By using the heat from sewers, we can lower energy bills because we're utilizing a resource that’s already available and doesn’t require additional energy to produce.
  • Reduces Waste:  It makes use of a byproduct (wastewater) in a useful way, which helps in managing resources more efficiently.



Real-World Impact

  • Energy Savings:  Imagine your building or home being heated with energy that would otherwise go to waste. It’s like getting free heating from the infrastructure we already have.
  • Environmental Benefits:  By cutting down on the need for other heating sources, we’re reducing pollution and our carbon footprint.

What Are Some Basic Ways of Learning About the Environmental Benefits of Sewer Thermal Technology?

By using these basic methods, you can gain a broader understanding of the introductory concepts of environmental benefits of sewer thermal technology.


Informational Websites:

  • Wikipedia:  Look up sewer thermal technology or waste heat recovery to get a general overview of how it works and its environmental benefits.
  • Environmental Organizations:  Visit websites of organizations like the Environmental Protection Agency (EPA) or the World Resources Institute (WRI) which might have accessible summaries or articles on related topics.
  • STEN:  A non-profit focus on developing the marketplace for sewage thermal energy use. 


Educational Videos:

  • YouTube:  Search for videos explaining sewer thermal technology and its benefits. Look for content aimed at a general audience that simplifies complex concepts.
  • TED Talks:  Watch talks on sustainable energy or waste heat recovery that might touch on sewer thermal systems.


News Articles:

  • Local & National News:  Find news articles that cover recent developments or projects involving sewer thermal technology. They often highlight the environmental benefits in an accessible way.


Infographics & Fact Sheets:

  • Infographics:  Search for visual representations that explain sewer thermal technology. Infographics can illustrate how it works and its positive environmental impacts.
  • Fact Sheets:  Look for fact sheets from environmental or energy organizations that summarize the benefits and key points about sewer thermal technology.


Brochures & Public Information Documents:

  • Local Government Publications:  Check out brochures or public documents from local municipalities that may have implemented sewer thermal projects and detail their environmental benefits.

A Sustainable Path Forward

Discover the potential of unused resources with the utilization of freely available heat contained within a sewer system for heating and cooling of the built environment. Wastewater heat recovery presents a compelling opportunity to enhance energy efficiency, reduce costs, and promote environmental sustainability across various industries and applications. By harnessing the untapped thermal energy present in wastewater streams, organizations can make significant strides towards a more resource-efficient future. With careful planning, implementation, and maintenance, wastewater heat recovery systems can deliver long-term benefits for both the bottom line and the planet.The Sewer Thermal Energy Network (STEN) invites you to send a message to begin a conversation that will give you the answers you need…
