Hi Mike, The grey water geothermal heat pump system operates exactly the same as the domestic water supply connections you see in the video. Yes you may connect a single family home to it. Of course, there must be a pressurized grey water line from the utility there. We have identified these lines in CA, TX, NM, CO, CT,NV,IN AZ. Most new housing developments will incorporate them as well. Lake water sourced heat exchangers work great too, like our Lake Travis project.
