@Source-Energy Pipe:
A carbon neutral reliable energy source

Concrete sewage pipe heat recovery system

@Source-Energy Pipe

The @Source-Energy Pipe is a precast concrete sewage (sanitary and storm) pipe with a heat recovery system embedded in the pipe wall. The system recovers heat from sewage effluent in the pipe and/or the ground surrounding the pipe. The system also rejects heat to the sewage effluent, the pipe and the ground surrounding the pipe, thus becoming a thermal battery.

The System is connected to and controlled by heat pumps in buildings. The heat pump functions to upgrade the low-level heat collected by the @Source-Energy System and to distribute the upgraded heat into the building.

In hot weather, the heat pumps reverse, removing heat from the building and rejecting that heat to the @Source-Energy Pipe, cooling the building. Heat rejected to the pipes is stored in the ground for recovery in cold weather to heat the building.

Composition of the System

@Source-Energy Pipes are installed as the public sewage pipe line which is usually buried along the street in front of the building. Each building is assigned a length of pipes as a heat recovery system. Plastic (HDPE) pipes connect the building to the System and are located at the lot line. A valve at the lot line is used to open or close the heat recovery System to that building. The building owner is usually responsible to connect a heat pump in the building to the heat recovery connections (pipes) at the lot line. Precast concrete pipes are custom engineered products with superior strength and durability. The @Source-Energy Pipes exceed the structural strength requirements of the CSA standard 3-edge bearing test.

What are the benefits from using @Source-Energy Pipes?

Who benefits from using @Source-Energy System?

  • Heating requirements for a 10-unit condominium – estimated to be to be 193,000 BTU/hr, could be met with approximately 600 ft of 300 mm @Source-Energy Pipe.
  • This could result in a saving of approximately $52,000 over installing geothermal wells, and the elimination of approximately 78.4T of CO2 per year over natural gas as the energy source, equivalent to removing 17 cars off the road.
  • Since a sewage line is being installed anyway, there is little additional work to installing @Source-Energy Pipes.
  • If the sewer line is on the condominium property, the ownership of their energy source can be very attractive to condominium purchasers.
  • A municipality converts its sewage pipes into a revenue source through selling energy to homeowners/businesses.
  • @Source-Energy Pipes are carbon neutral thereby assisting municipalities to meet their carbon targets.
  • Green communities are more attractive to residential and business property purchasers, thereby increasing the municipality’s tax base.
  • In a 10,000-home community the CO2 reduction would be approximately 78,000 T of CO2 per year and the equivalent of elimination of 17,000 cars off the road.
  • Manufacturing of @Source-Energy Pipes creates local jobs in the community.
  • @Source-Energy Pipes can be the primary component of a district energy system.
  • Homeowners have the advantage of a dependable energy source without the burden of annual increases in costs associated with conventional energy sources.
  • Home resale values are higher for those with green energy.
  • @Source-Energy Pipes provide a safe, reliable energy source.
  • Homes on the @Source-Energy System do not have an unsightly chimney belching out carbon gas into the atmosphere.
  • There are no geothermal loops or wells on the home-owners property.
  • A license to manufacture @Source-Energy Pipes is a new business opportunity.
  • Local concrete pipe manufacturers licensed by R3C to manufacture @Source-Energy Pipes creates jobs and brings new revenue to the community.
  • Energy providers are licensed by R3C to manage the energy moved through @Source-Energy Pipes.
  • Energy providers fund the installation of the @Source-Energy Pipes and collect energy delivery fees from homeowners and businesses connected to the energy system. This reduces the cost to developers.
  • @Source-Energy Pipes can be the primary component of a district energy system.
  • Energy providers may be electrical utilities, municipal works and industrial enterprises.
