An exchanger for a pool, large storage tank, or pond is described herein. In one embodiment, the exchanger includes a diffuser hub, exchanger extension arms that extend radially outward from the diffuser hub, one or more exchanger rings that intersect with the heat exchanger extension arms, and a fill tube that extends to the diffuser hub. One or both of the heat exchanger arms and/or the exchanger rings include fluid apertures that direct fluid into the pool. Fluid pumped into the fill tube may flow through into the diffuser, through the exchanger extension arms and/or the one or more exchanger rings, and out through the fluid apertures at various locations into the pool. As such, heated fluid, or fluid to be mixed, for example, may be more evenly and quickly distributed into the pool.

The invention relates to wastewater treatment systems with decentralized disposal of treated wastewater and methods of using the same. The invention further relates to methods of converting existing septic systems to a wastewater treatment plant system.

A system for transporting and collecting bio-waste without the use of water as a carrier of the bio-waste is disclosed. The system comprises a plurality of bio-waste carts configured to receive and transport bio-waste along a plurality of predefined pathways to a central chute. The system further comprises a bio-waste depository associated with the central chute. The system further comprises a transport system comprising a plurality of locomotive devices configured to advance and return the plurality of bio-waste carts along predefined pathways and through tunnel-like structures to and from the central chute.

A system for receiving and transporting bio-waste without the use of water as a carrier of the bio-waste is disclosed. The system comprises a bio-waste receptacle configured to receive bio-waste and is associated with an exterior wall of a structure. The system further comprises a bio-waste cart receivable at least partially within the bio-waste receptacle and comprising a base and a collection bucket for receiving the bio-waste, the base having a plurality of wheels for transporting the collection bucket. The system further comprises a transport system for moving the bio-waste cart along a pre-defined pathway, the transport system comprising a tunnel-like structure and a mechanical, manually operated locomotive device and wherein the tunnel-like structure conceals the pre-defined pathway and at least a portion of the mechanical, manually operated locomotive device. The system further comprises a bio-waste depository positioned on the pre-defined pathway for receiving the transported bio-waste.

A tank for waste water partially or fully buried in the ground or immersed in water includes a wall made of a high thermal conductivity material, which in turn has a pair of walls forming a cavity creating a circuit of a convective fluid for heat exchange with both the waste water contained inside the tank and with the ground and/or groundwater external to the tank.
