Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. patent application Ser. No. 18/612,490, filed Mar. 21, 2024, which claims the benefit of U.S. Provisional Application No. 63/495,018, filed Apr. 7, 2023, and titled “DUMPSTER SIDEWALL EXTENSION” the disclosure of which is hereby incorporated herein by reference. TECHNICAL FIELD The present disclosure relates generally to waste collection systems, and more particularly to a combined waste collection and sanitation system incorporating a dumpster and portable toilet unit with integrated sidewall extensions and a roll-off tarp coverage mechanism. BACKGROUND A combination roll-off dumpster with a portable toilet, sometimes referred to as a combination dumpster, can be particularly useful on construction sites and renovation projects, where both waste disposal and sanitation facilities are needed. The combination dumpster integrates a portable restroom with a standard roll-off dumpster, providing a two-in-one solution that saves space and offers convenience to workers on the site. One example of a combination roll-off dumpster with a portable toilet is disclosed in U.S. Pat. No. 7,966,675, filed Mar. 18, 2007, the contents of which are incorporated by reference herein in their entirety. During transport both the portable toilet and the roll-off dumpster are covered with a tarp, typically extending from front to back. The problem, however, is that the top of the portable toilet typically extends about two to three feet higher than the top edge of the walls surrounding the roll-off dumpster enclosure. Accordingly, when the tarp is stretched from front to back a large triangular void or opening is present on the sides, between tarp and the top edge of the roll-off dumpster wall potentially allowing debris and litter to escape during transit. The need to address this potential containment issue is not only a matter of maintaining cleanliness and safety standards during transport, but also a regulatory requirement. SUMMARY Embodiments described herein can provide a combined waste removal and sanitation solution, and may incorporate various aspects as disclosed herein in any combination. In one aspect, a chassis forms the foundational support for a combined dumpster and portable toilet system, enhancing structural integrity and mobility.
