Waste Pumping System
A waste pumping system is provided that includes a tank having a floor, a body, and a tank inlet. Embodiments include those wherein the system includes a first designated area formed by a first baffle portion and the body, a second designated area formed by a second baffle portion and the body, and a third baffle portion for directing material toward the first designated area. In some embodiments, the system includes a pump substantially disposed within the first designated area and a sensing system substantially disposed within the second designated area for activating the pump when material within the tank reaches a predetermined level.

6 . The pumping system of claim 3 , wherein the fourth baffle portion is substantially vertical and has a concave surface with respect to the tank inlet.
7 . The pumping system of claim 1 , wherein the first baffle portion and the second baffle portion are substantially vertical and semi-circular.
8 . The pumping system of claim 1 , further comprising a gap between the first baffle portion and one of: the floor and the body, and a gap between the second baffle portion and one of: the floor and the body.
9 . The pumping system of claim 1 , wherein the third baffle portion extends from the second baffle portion.
10 . The pumping system of claim 1 , wherein the third baffle portion comprises a ramp sloping downward toward the first designated area.
11 . The pumping system of claim 10 , wherein the third baffle portion has a curved surface.
12 . The pumping system of claim 1 , further comprising a pump substantially disposed within the first designated area.
13 . The pumping system of claim 12 , further comprising a sensing system substantially disposed within the second designated area for activating the pump when material within the tank reaches a predetermined level.
14 . The pumping system of claim 1 , further comprising a sensing system substantially disposed within the second designated area.
15 . The pumping system of claim 1 , further comprising a toilet having an outlet in fluid communication with the tank inlet.
16 . The pumping system of claim 1 , wherein the floor descends from a portion of the tank opposite the first designated area toward the first designated area.
17 . A pumping system comprising:
a tank having a floor, a body, and a tank inlet;
a pump disposed substantially within the tank;
a sensing system disposed substantially within the tank for activating the pump when material within the tank reaches a predetermined level;
means for shielding the pump;
means for shielding the sensing system; and
means for directing flow toward the pump.
18 . The pumping system of claim 17 , wherein the pump is substantially contained within a first designated area and the sensing system is substantially contained within a second designated area.
19 . The pumping system of claim 17 , wherein the means for shielding the pump, the means for shielding the sensing system, and the means for directing flow toward the pump are formed from a single structural element.
20 . The pumping system of claim 17 , further comprising means for deflecting the inlet flow.
21 . The pumping system of claim 20 , wherein the means for shielding the pump, the means for shielding the sensing system, the means for directing flow toward the pump, and the means for deflecting the inlet flow are formed from a single structural element.
22 . The pumping system of claim 17 , further comprising a toilet having an outlet in fluid communication with the tank inlet.
23 . The pumping system of claim 17 , wherein the floor descends from a portion of the tank opposite the pump toward the pump.
24 . A pumping system comprising:
a tank having a floor, a body, and a tank inlet;
a first designated area formed by a first baffle portion and the body;
a second designated area formed by a second baffle portion and the body;
