Portable toilet in the context of "Unisex"

Container-based sanitation (abbreviated as CBS) refers to a sanitation system where toilets collect human excreta in sealable, removable containers (also called cartridges) that are transported to treatment facilities. This type of sanitation involves a commercial service which provides certain types of portable toilets, and delivers empty containers when picking up full ones. The service transports and safely disposes of or reuses collected excreta. The cost of collection of excreta is usually borne by the users. With suitable development, support and functioning partnerships, CBS can be used to provide low-income urban populations with safe collection, transport and treatment of excrement at a lower cost than installing and maintaining sewers. In most cases, CBS is based on the use of urine-diverting dry toilets.

A key benefit of container-based sanitation systems is its relative low-cost. In addition, the process assures there is no human contact with excreta. Feces can be contained, carried, transported and emptied into treatment facilities without exposing humans to pathogens.

A chemical toilet collects human waste in a holding tank and uses chemicals to minimize odors. They do not require a connection to a water supply and are used in a wide variety of situations. These toilets are usually, but not always, self-contained and movable. A chemical toilet is structured around a relatively small tank, which requires frequent emptying. It is not connected to a hole in the ground (like a pit latrine), nor to a septic tank, nor is it plumbed into a municipal system leading to a sewage treatment plant. When the tank is emptied, the contents are usually pumped into a sanitary sewer or directly to a treatment plant.

The enclosed portable toilets used on construction sites and at large gatherings such as music festivals are well-known types of chemical toilets. As they are usually used for short periods and because of their high prices, they are mostly rented rather than bought, often including servicing and cleaning.

A public toilet, restroom, bathroom or washroom is a room or small building with toilets (or urinals) and sinks for use by the general public. The facilities are available to customers, travelers, employees of a business, school pupils or prisoners. Public toilets are typically found in many different places: inner-city locations, offices, factories, schools, universities and other places of work and study. Similarly, museums, cinemas, bars, restaurants, and entertainment venues usually provide public toilets. Railway stations, filling stations, and long distance public transport vehicles such as trains, ferries, and planes usually provide toilets for general use. Portable toilets are often available at large outdoor events.

Public toilets are commonly separated by sex (or gender) into male and female toilets, although some are unisex (gender-neutral), especially for small or single-occupancy public toilets. Public toilets are sometimes accessible to people with disabilities. Depending on the culture, there may be varying degrees of separation between males and females and different levels of privacy. Typically, the entire room, or a stall or cubicle containing a toilet, is lockable. Urinals, if present in a male toilet, are typically mounted on a wall with or without a divider between them.

A Hesco bastion,also known as a Hesco barrier, and formally Concertainer, is a gabion introduced in 1989 and primarily used for flood control and military fortifications. It is made of a collapsible wire mesh container and heavy-duty geotextile fabric liner and is used as a temporary to semi-permanent levee or blast wall against small-arms fire or explosives. It has been used in military applications in Iraq and Afghanistan.
