National Western Center and Partners Launch Largest Wastewater Heat Recovery System in the United States

New district energy system will heat and cool buildings with recycled thermal energy from nearby wastewater pipeline, in pursuit of a low-carbon campus

DENVER – The National Western Center (NWC) and its partners are striving to create a low-carbon campus that’s sustainable and regenerative. Today the partners celebrated taking the next steps in the implementation of that vision by launching the largest wastewater heat recovery system in the United States to date.

Used water that goes down the drains of our showers, sinks, bathtubs, dishwashers, washing machines and toilets travels through a main sewer pipeline. Within the NWC’s wastewater heat recovery system, a plate and frame heat exchanger captures the warmth of that wastewater and transfers it to a clean water distribution pipe. The system is housed in an 8,790-square-foot central utility plant (CUP) constructed of a pre-engineered metal building. The distribution pipe enters into individual buildings using a closed-loop system (clean water never touches wastewater) and harnesses the energy from the system to heat and cool the buildings.

“We made a promise to be at the forefront of sustainability, and we’re delivering,” National Western Center CEO Brad Buchanan said. “Knowing we have to heat and cool our buildings one way or another, we chose an innovative, clean-energy system that’s both beneficial for our campus but also for our community.”

The system was designed, built and will be operated by EAS Energy Partners (EAS), through an agreement with the National Western Center. EAS is comprised of CenTrio, the largest core-competency district energy operator in the United States, AECOM Technical Services Inc., and Colorado-based Saunders Construction. The system is being delivered at a cost comparable to traditional natural gas systems but is low carbon, consistent and sustainable.

“The leadership from all the partners helped bring about the largest sewer heat recovery system in the United States and demonstrates the sustainability success we can have when we work together to create and deliver innovative, affordable and reliable energy solutions to our customers.  EAS is excited about this milestone in the project as the district comes on-line.  CenTrio is looking forward to its continued partnership with the National Western Center Authority as we integrate this asset into our operations and become a trusted partner to the community.”

Reducing fossil fuel use means reducing air pollution and associated health impacts. To build the system, the City and County of Denver’s construction team had to bury the 72-inch wastewater pipeline that once ran alongside the South Platte River, alleviating its odors and opening up recreational space for people enjoy.

“The District Energy System exemplifies the City’s commitment to innovation, sustainability, and resiliency. This system will serve as a model for other cities and help to educate and promote clean energy solutions,” said Tykus Holloway, Executive Director for the Mayor’s Office of the National Western Center / City and County of Denver.
