What is claimed is:

1. A wastewater treatment system comprising:
a potable water subsystem in valved fluid communication with a potable water user source;
a gray water subsysten in valved fluid communication with a drain associated with at least one potable water user source and at least one toilet whereby water used by the potable water source passes to the gray water subsystem and is used for toilet flushing;
a black water subsystem in valved fluid communication with at least one blackwater source whereby water passes to the black water subsystem upon use.
2. The wastewater treatment system of claim 1 wherein the system is installed on a vehicle selected from the group consisting of RVs, boats, trains, cruiseships and planes.
3. The wastewater treatment system of claim 1 wherein movement of water is controlled by a programmable logic controller (PLC).
4. The wastewater treatment system of claim 1 wherein a water filter is disposed between the gray water subsystem and potable water subsystem.
5. The wastewater treatment system of claim 4 wherein the water filter is a reverse-osmosis filter.
6. The wastewater treatment system of claim 1 further comprising an oxidation source.
7. The wastewater treatment system of claim 6 wherein the oxidation source is an ozone generator.
8. The wastewater treatment system of claim 3 wherein the graywater subsystem further comprises:
a water level sensor communicatively coupled to the PLC;
an ORP sensor communicatively couple to the PLC for transmitting a signal responsive to the detection of a predetermined ORP level in the water; and a disinfection/oxidation loop.
9. The wastewater treatment system of claim 8 wherein water enters the disinfection/oxidation loop responsive to the detection of a predetermined ORP level in the water.
10. The wastewater treatment system of claim 8 further comprising an oxidation source.
11. The wastewater treatment system of claim 10 wherein the oxidation source is an ozone generator.
12. The wastewater treatment system of claim 10 wherein the oxidation source is in valved fluid communication with the disinfection/oxidation loop.
13. The wastewater treatment system of claim 3 wherein the potable water subsystem further comprises:
a water level sensor;
an ORP sensor communicatively coupled to the PLC for transmitting a signal responsive to the detection of a predetermined ORP level in the water; and
a disinfection/oxidation loop.
14. The wastewater treatment system of claim 13 wherein water enters the disinfection loop responsive to the detection of a predetermined ORP level in the water.
15. The wastewater treatment system of claim 13 further comprising an oxidation source.
16. The wastewater treatment system of claim 15 wherein the oxidation is an ozone generator.
17. The wastewater treatment system of claim 15 wherein the oxidation source is in valved, fluid communication with the disinfection loop.
18. The wastewater treatment system of claim 3 wherein the blackwater subsystem further comprises:
a water level sensor;
a temperature sensor;
a heater; and
a mixing/aeration loop.

19. The wastewater treatment system of claim 18 further comprising a settling unit in valved fluid communication with the blackwater subsystem and graywater subsystem.
20. The wastewater treatment system of claim 19 wherein the settling unit is chosen from the group consisting of a column and conical-bottom tank.
21. The wastewater system of claim 19 wherein the settling unit further comprises a level sensor communicatively coupled to the PLC.
22. The wastewater treatment system of claim 3 wherein the blackwater subsystem further comprises:
an oxic tank having a mixing/aeration loop; and
an anoxic tank having a mixing loop in valved fluid communication with the oxic tank.
23. The wastewater treatment system of claim 22 further comprising a settling unit in valved fluid communication with the anoxic tank.
24. The wastewater treatment system of claim 23 wherein the settling unit is chosen from the group consisting of a column and conical-bottom tank.
25. The wastewater system of claim 23 wherein the settling unit further comprises a level sensor communicatively coupled to the PLC.
26. The wastewater system of claim 1 wherein a macerator pump is disposed between at least one blackwater source and the blackwater subsystem.
