## Abstract

A disposal system utilizing a direct injection of water for an amount of time to sufficiently sanitize a chamber of the disposal system. The disposal system includes a chamber coupled to a drain of a sink at a first end of the chamber, and to a drainpipe at a second end of the chamber. A cutting mechanism, such as a rotary cutting blade, is positioned within the chamber near a floor of the chamber. A fluid-injection unit, such as a flange attachment, coupled to the first end of the chamber and the drain of the sink, includes a plurality of nozzles for introducing a fluid in a variety of streams in different directions to reach substantially an entirety of the chamber. The flange attachment can also include a water line attachment for connecting to a water line, with an optional ozone generator upstream from the disposal system.

### Claim 3 (depends on 2)

The waste disposal system of claim 2, wherein each nozzle of the plurality of nozzles is oriented at an angle a radius defined by the inner surface of the hollow ring such that the fluid-injection unit is configured to deliver fluid into the chamber as a plurality of angled fluid streams.

### Claim 4 (depends on 1)

The waste disposal system of claim 1, wherein the fluid inlet comprises a stem, and wherein the fluid source is removably couplable to the stem.

### Claim 5 (depends on 1)

The waste disposal system of claim 1, further comprising an ozone generator positioned between the fluid source and the fluid inlet, wherein the system is configured to direct fluid from the fluid source through the ozone generator, the ozone generator being configured to generate ozonated water for injection into the waste disposal unit.

### Claim 6 (depends on 1)

The waste disposal system of claim 1, further comprising a cleaning agent repository in fluid communication with the structure, wherein the system is configured to direct a cleaning agent from the cleaning agent repository into the fluid for cleaning the chamber.

### Claim 7 (depends on 1)

The waste disposal system of claim 1, further comprising a solenoid assembly having at least a first solenoid valve, wherein the solenoid assembly is configured to receive signals from associated sensors or actuators, and wherein, in response to received signals, the solenoid assembly causes the first solenoid valve to open and allow fluid to enter the direct injection assembly.

### Claim 8 (depends on 1)

The waste disposal system of claim 1, further comprising a valve configured to control and operate waste disposal unit, wherein the valve includes an independent power source and a relay to activate and deactivate the waste disposal unit.

### Claim 9 (depends on 8)

The waste disposal system of claim 8, wherein the valve includes an integrated power monitor configured to measure electrical current to determine a loaded consumption and an unloaded consumption of the cutting mechanism, thereby indicating when the cutting mechanism is in active use.

### Claim 10 (depends on 9)

The waste disposal system of claim 9, wherein the integrated power monitor is further configured to monitor run-cycle timing to enhance elimination of wastewater from the waste disposal unit.

### Claim 11 (depends on 1)

The waste disposal system of claim 1, further comprising:
a splashguard configured to seat in the drain opening of the sink assembly, the splashguard comprising a sidewall, a base portion extending below a bottom edge of the sidewall, and a plurality of inverted petals extending within a perimeter of the sidewall.

### Claim 12 (depends on 11)
