Vancouver pursues claim that “almost any building can recover heat from wastewater to reduce natural gas consumption by 30-100%”

By  August 10th, 2016 

Under the aegis of its Renewable City Strategy, the city of Vancouver has committed to generate 100% of its energy from renewable sources before 2050.

In implementing this renewable energy goal, International Wastewater Systems (IWS) has announced a series of wastewater heat recovery projects will be installed in Vancouver. The installations will be launched in partnership with both public and private sector interests.

Ontario recently announced its $8.3 billion climate change plan with initiatives focusing on encouraging buildings to switch to more energy-efficient heating systems. IWS is developing its pipeline of projects in British Columbia and Ontario which are expected to contribute to the implementation of Canadian policy initiatives.

“The simple fact is water enters our buildings at 7-9 degrees Celsius and leaves at 20-25 degrees Celsius. If captured, this wasted heat could be used to fulfill 40-50% of our buildings energy requirements,” said IWS CEO Lynn Mueller in a press announcement.

IWS has stated it will manufacture, install and service the equipment for the following newly announced sewage heat recovery projects:

  • Metro Vancouver’s inaugural wastewater heat recovery project at The South East False Creek Neighborhood Energy Utility, a wastewater heat recovery project supplying a District Heating Network. The project represents the first installation of the SHARC 880 wastewater heat recovery system. The installation will include two SHARC 880 systems working in tandem.
  • British Columbia Housing Management Commission and IWselected the initial buildings to be retrofitted with IWS’s PIRANHA technology, a self-contained heat pump which extracts thermal energy from wastewater for domestic hot water production.

“We are enthusiastic to partner with the province in the implementation of its carbon reduction strategy,” said Mueller. ‘Using IWS technology, almost any building can recover heat from wastewater to reduce natural gas consumption by 30-100%.”

These wastewater recovery systems are expected to be significant tools in meeting the Renewable City Strategy of Vancouver.
