US 12,188,219 B1 · Portable restroom system and a noise-reducing and less labor-intensive method for draining portable restrooms

Abstract

A portable restroom system for use in a multilevel building under construction, a noise-reducing and less labor-intensive method for draining the portable restrooms in the inventive system, and a method of remotely controlling the power take-off (PTO) mechanism of a sanitation truck, which powers the truck's vacuum system, are provided. A notable advantage of the present invention is that it allows for the PTO of a sanitation truck to be controlled remotely. This allows the truck's vacuum system to be operated intermittently or only as needed, thereby limiting the high levels of noise from the exhaust airflow, which is disruptive to areas adjacent to the construction site. Another notable advantage of the present invention is that it obviates the need to transport each portable restroom down to a ground level or floor of the building under construction for service (e.g., drainage and cleaning/sanitizing), which saves both time and labor.

Dependent claims

A portable restroom system for use in a multilevel building under construction, which comprises:

a plurality of portable restrooms, each having at least one sanitary fixture;
and
a pipe and a water line that each extend substantially vertically through the multilevel building,
wherein a first portable restroom is located on one level or floor of the building, and a second portable restroom is located on another level or floor of the building,
wherein the pipe and the water line each have a plumbing connection located on each level or floor of the building with one or more portable restrooms,
wherein the pipe also has a plumbing connection on a ground floor of the building allowing for fluid access to a vacuum system of a sanitation truck having a power take-off device, and
wherein the vacuum system is powered by the truck's power take-off device,
wherein the multilevel building under construction has more than ten floors, and wherein the substantially vertically extending pipe located at or above the tenth floor has at least one of:
(a) one or more reduced diameter sections;
and (b) one or more power booster sub-stations positioned along and in fluid communication with the pipe.

A noise-reducing and less labor-intensive method for draining a plurality of portable restrooms in a portable restroom system for use in a multilevel building under construction, which includes:

a plurality of portable restrooms, each having at least one sanitary fixture;
and a pipe and a water line that each extend substantially vertically through the multilevel building, wherein a first portable restroom is located on one level or floor of the building, and a second portable restroom is located on another level or floor of the building, wherein the pipe and the water line each have a plumbing connection located on each level or floor of the building with one or more portable restrooms, wherein the pipe also has a plumbing connection on a ground floor of the building allowing for fluid access to a vacuum system of a sanitation truck having a power take-off device, and wherein the vacuum system is powered by the truck's power take-off device, wherein the method comprises:
fluidly connecting a vacuum-like hose from the sanitation truck to the pipe's ground floor plumbing connection;
and
in succession on each floor of the building containing the one or more portable restrooms:
(a) opening the pipe's plumbing connection;
(b) fluidly connecting the pipe to a portable restroom;
(c) remotely starting the vacuum system of the sanitation truck;
(d) removing waste from the portable restroom;
(e) remotely stopping the vacuum system of the sanitation truck;
(f) repeating steps (b)-(e) until waste has been removed from each portable restroom on the floor;
and then
(g) closing the pipe's plumbing connection,
wherein the method further comprises cleaning the one or more portable restrooms after waste removal,
wherein the at least one sanitary fixture of the plurality of portable restrooms includes a toilet with a toilet bowl, at least one holding or septic tank, and optionally, one or more plumbing connections, wherein cleaning the one or more portable restrooms after waste removal comprises cleaning the toilet bowl using pressurized water from the water line and a biocidal spray to kill bacteria and microbes, and refilling the at least one holding or septic tank with water from the water line, and a chemical deodorizer.
