An improved greywater disposal system is provided which substantially eliminates onboard standing greywater. The system includes one or more onboard plumbing fixtures fluidly connected to a greywater sump. The bottom of the greywater sump is sloped toward a drain therein at a low end. The prongs of a sensor may be suspended in the sump drain and/or in an inlet chamber defined at an inlet end of the greywater sump. The sensor is associated with a controller and sump or bilge pump. The pump is turned on when the prong tips of the sensor become immersed in greywater which occurs substantially simultaneously with the production of the greywater. The onboard plumbing fixtures include one or more sinks, showers, bathtubs, washing machines and air conditioning units. The system may be used on boats, ships, RVs, campers or the like.

I claim: 1. A greywater disposal system for onboard plumbing fixtures, comprising: a greywater sump for receiving greywater from one or more onboard plumbing fixtures, the greywater sump having a sump drain in a bottom wall, the bottom wall sloped toward the sump drain; a pump in fluid communication with the greywater sump; at least one sensor mounted within the greywater sump and associated with a controller for automatically activating the pump simultaneously with the introduction of greywater into the sump to dispose of the greywater within the greywater sump; wherein the sump drain has an upper portion and a lower portion; wherein the at least one sensor is a conductive electrode sensor with a pair of sensor prongs; and wherein the conductive electrode sensor is suspended vertically above a center of the sump drain and both tips of the sensor prongs are positioned in the upper portion of the sump drain. 2. The greywater disposal system of claim 1, wherein the greywater sump comprises a first and second endwall, a pair of sidewalls, a top wall, and the bottom wall, the bottom wall sloped from the first and second endwalls toward the sump drain and from the pair of sidewalls toward the sump drain. 3. The greywater disposal system of claim 1, wherein the greywater sump further comprises a chamber wall between the first endwall and the sump drain, the chamber wall defining an inlet chamber at one end of the greywater sump and the chamber wall extending to the bottom wall of the sump and having at least one opening at a bottom portion thereof to permit egress of greywater from the inlet chamber to the sump drain, the at least one sensor mounted on the chamber wall. 4. The greywater disposal system of claim 3, wherein the at least one sensor is mounted on the chamber wall within the inlet chamber of the greywater sump and wherein the tips of the sensor prongs extend across a portion of the opening at the bottom portion of the chamber wall and are positioned in the upper portion of the sump drain. 5. The greywater disposal system of claim 3, wherein one sensor is mounted proximate the sump drain and at least a portion of the pair of sensor prongs is positioned within an upper portion of the sump drain and wherein a second sensor is mounted on the chamber wall within the inlet chamber of the greywater sump. 6. The greywater disposal system of claim 1, wherein the one or more onboard plumbing fixtures are on a boat. 7. The greywater disposal system of claim 1, wherein the pump is a bilge pump suspended within the greywater sump. 8. The greywater disposal system of claim 1, wherein the pump is a sump pump. 9. A greywater disposal system, comprising: a greywater sump having a first and second endwall, a pair of sidewalls, a top wall, and a bottom wall, the bottom wall defining a sump drain and sloped toward the sump drain; a plurality of inlet ports in the first endwall and an inlet chamber defined at one end of the greywater sump by a chamber wall between the first endwall and the sump drain, the chamber wall having an opening at the bottom thereof to permit egress of the greywater from at least one of the plurality of inlet ports to the sump drain; a pump for pumping the greywater out of the greywater sump; and at least one sensor mounted on the chamber wall inside the inlet chamber of the greywater sump and associated with a controller for automatically activating the pump as greywater exits the inlet chamber through the opening in the chamber wall to discharge the greywater from the greywater sump simultaneously with the introduction of greywater into the sump; wherein the at least one sensor is a conductive electrode sensor with a pair of sensor prongs; and wherein tips of the sensor prongs extend across a portion of the opening at the bottom of the chamber wall, are suspended vertically above a center of the sump drain, and are positioned in an upper portion of the sump drain. 10. The greywater disposal system of claim 9, wherein the greywater sump receives greywater through one or more drain pipes from one or more onboard plumbing fixtures. 11. The greywater disposal system of claim 10 wherein the one or more onboard plumbing fixtures are on a boat. 12. The greywater disposal system of claim 9, wherein the pump turns off after a delay to substantially empty the greywater sump. 13. A method of disposing of onboard greywater comprising the steps of: providing a greywater sump for receiving greywater from onboard washing activity using one or more onboard plumbing fixtures, said greywater sump having a sump drain at a low point thereof; and providing at least one sensor in said greywater sump to close an electrical circuit to automatically activate an associated pump to pump said greywater out of the greywater sump during the onboard washing activity simultaneously with the introduction of greywater into the sump; wherein the sump drain has an upper portion and a lower portion; wherein the at least one sensor is a conductive electrode sensor with a pair of sensor prongs; and wherein the conductive electrode sensor is suspended vertically above a center of the sump drain and both tips of the sensor prongs are positioned in the upper portion of the sump drain. 14. The method of claim 13, wherein the electrical circuit opens when the greywater sump is substantially empty and the pump turns off after a delay following the opening of the electrical circuit. 15. The method of claim 13, wherein the greywater sump comprises a first and second endwall, a pair of sidewalls, a top wall, and a bottom wall, the bottom wall sloped toward the sump drain defined therein. 16. The method of claim 15, wherein the greywater sump further comprises a chamber wall between the first endwall and the sump drain, the chamber wall defining an inlet chamber at one end of the greywater sump and having at least one opening therein to permit egress of the greywater from the inlet chamber to the sump drain, the at least one sensor mounted on the chamber wall.
