Wastewater for District Energy

Harness wastewater to reduce CO2, costs & energy consumption!

Why are cities turning to wastewater for clean energy?





How does wastewater work with district energy?

The collective wastewater from city blocks & large industrial areas carries a massive amount of energy that can be recaptured and redirected to supplement existing heat/energy production. 

For cooling, you can inject unwanted heat into wastewater to get rid of it, thereby reducing the load on other cooling & air-conditioning.  In hot climates or draught conditions, this can save millions of gallons of fresh water that would be used by cooling towers.

Key benefits of wastewater for district energy

Reduces load on Cooling Towers

Cooling Towers require enormous amounts of fresh water to do cooling, so by offloading them using wastewater energy you save huge amounts of fresh water.

Feeds District-level Thermal Loops

Wastewater can contribute to thermal loops that other buildings utilize for heating/cooling.

Supplements hot water production

You can redirect unwanted building heat to supplement hot water production, reducing energy requirements on boilers & other heating.

Forward-thinking cities, states and countries are discovering the forgotten power of wastewater to help them achieve their climate goals ahead of schedule.

Case Study

Seattle's King County

A clean energy template for other cities to follow

Other cities can repeat the proven success of Seattle’s King County Clean Energy District and leap their sustainability goals forward and support the local clean energy economy.
