A heat exchanger placed underneath an elevated tub or shower stall or under the bathroom floor includes a flat top heat conductive plate. The top plate is fastened to a flat lower plate, having a serpentine pattern with a shallow depth embedded into the top surface. When the top plate is fastened and sealed to the lower plate, the flow of the incoming cold water is contained within the confines of the serpentine lower plate of the heat exchanger. Heat is transferred from the grey waste water falling onto the top plate to preheat the incoming cold water flowing underneath the top plate in the serpentine conduit chamber of the lower plate in contact with a bottom surface of the top plate. The cold water is thereby preheated and used as a substitute for the incoming cold water that would be normally plumbed to the discharge shower head.

Embodiments of the present invention provide a system to direct water flow through a lavatory and to cleanse grey water through a series of treatment steps. The water may then be re-directed to the faucet for re-use in hand washing or other potable water use or to the toilet for flush water. The treatment steps are altered, depending upon the ultimate use of the water, as flush water need not be treated to the same level as potable water. The system may also function via a cascade of logic commands given by a series of electronic controllers, valves, and sensors which are fine-tuned to supply enough water to each component of the system.
