Outhouse

Outhouse is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Outhouse rather than just read about it. In short: An outhouse — known variously across the English-speaking world otherwise as bog, dunny, long-drop, or privy — is a small structure, separate from a house or main building, which covers a toilet. This is typically either a pit latrine or a bucket toilet, but other forms of dry (non-flushing) toilets may be encountered.

Key takeaways

  • Outhouse belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Outhouse to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Outhouse from memory before moving on to harder problems.

Reference excerpt

An outhouse — known variously across the English-speaking world otherwise as bog, dunny, long-drop, or privy — is a small structure, separate from a house or main building, which covers a toilet. This is typically either a pit latrine or a bucket toilet, but other forms of dry (non-flushing) toilets may be encountered. The term may also be used to denote the toilet itself, not just the structure. Outhouses were in use in cities of developed countries (e.g. Australia) well into the second half of the twentieth century. They are still common in rural areas and also in cities of developing countries. Outhouses that are covering pit latrines in densely populated areas can cause groundwater pollution.

Design aspects

Common features

Outhouses vary in design and construction. They are by definition outside the dwelling, and are not connected to plumbing, sewer, or septic system. The World Health Organization recommends they be built a reasonable distance from the house balancing issues of easy access versus that of smell. The superstructure exists to shelter the user, and also to protect the toilet itself. The primary purpose of the building is for privacy and human comfort, and the walls and roof provide a visual screen and some protection from the elements. The outhouse also has the secondary role of protecting the toilet hole from sudden influxes of rainwater, which would flood the hole and flush untreated wastes into the underlying soils before they can decompose. Outhouses are commonly humble and utilitarian, made of lumber or plywood. This is especially so they can easily be moved when the earthen pit fills up. Depending on the size of the pit and the amount of use, this can be fairly frequent, sometimes yearly. As pundit "Jackpine" Bob Cary wrote: "Anyone can build an outhouse, but not everyone can build a good outhouse." Floor plans typically are rectangular or square, but hexagonal outhouses have been built. The arrangements inside the outhouse vary by culture. In Western societies, many, though not all, have at least one seat with a hole in it, above a small pit. Others, often in more rural, older areas in European countries, simply have a hole with two indents on either side for the user's feet. In Eastern societies, there is a hole in the floor, over which the user crouches. A roll of toilet paper is usually available. Old corn cob, leaves, or other types of paper may instead be used. The decoration on the outhouse door has no standard. The well-known crescent moon on American outhouses was popularized by cartoonists and had a questionable basis in fact. There are authors who claim the practice began during the colonial period as an early "mens"/"ladies" designation for an illiterate populace (the sun and moon being popular symbols for the sexes during those times). Others dismiss the claim as an urban legend. What is certain is that the purpose of the hole is for venting and light and there were a wide variety of shapes and placements employed.

Toilet types covered by outhouse shelters The shelter may cover very different sorts of toilets.

Pit latrines

An outhouse often provides the shelter for a pit latrine, which collects human feces in a hole in the ground. When properly built and maintained they can decrease the spread of disease by reducing the amount of human feces in the environment from open defecation. When the pit fills to the top, it should be either emptied or a new pit constructed and the shelter moved or re-built at the new location. The management of the fecal sludge removed from the pit is complicated. There are both environment and health risks if not done properly. As of 2013 pit latrines are used by an estimated 1.77 billion people. This is mostly in the developing world as well as in rural and wilderness areas.

Bucket toilet

Another system is the bucket toilet, consisting of a seat and a portable receptacle (bucket or pail). These may be emptied by their owners into composting piles in the garden (a low-tech composting toilet), or collected by contractors for larger-scale disposal. Historically, this was known as the pail closet; the municipality employed workers, often known as "nightmen" (from night soil), to empty and replace the buckets. This system was associated in particular with the English town of Rochdale, to the extent that it was described as the "Rochdale System" of sanitation. 20th century books report that similar systems were in operation in parts of France and elsewhere in continental Europe. The system of municipal collection was widespread in Australia; "dunny cans" persisted well into the second half of the twentieth century, see below. In Scandinavia and some other countries, outhouses are built over removable containers that enable easy removal of the waste and enable much more rapid composting in separate piles. A similar system operates in India, where hundreds of thousands of workers engage in manual scavenging, i.e. emptying pit latrines and bucket toilets without any personal protective equipment.

Drums and barrels in national parks

A variety of systems are used in some national parks and popular wilderness areas, to cope with the increased volume of people engaged in activities such as mountaineering and kayaking. The growing popularity of paddling, hiking, and climbing has created special waste disposal issues throughout the world. It is a dominant topic for outdoor organizations and their members. For example, in some places the human waste is collected in drums which need to be helicoptered in and out at considerable expense. Alternatively, some parks mandate a "pack it in, pack it out" rule. Many reports document the use of containers for the removal of excrement, which must be packed in and packed out on Mount Everest. Also known as "expedition barrels" or "bog barrels", the cans are weighed to make sure that groups do not dump them along the way. "Toilet tents" are erected. There has been an increasing awareness that the mountain needs to be kept clean, for the health of the climbers at least.

Composting toilets

Worm hold privies, another variant of the composting toilet, are being used by Vermont's Green Mountain Club. These simple outhouses are stocked with red worms (a staple used by home composters). Composting toilets are also subject to regulations. The "Clivus Multrum" is another type of composting toilet which can be inside of an outhouse.

Worked examples

Example 1 — a first encounter with Outhouse

Start with the simplest possible case. Write down what Outhouse claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Outhouse before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Outhouse ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Outhouse

In research
Outhouse appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Outhouse in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Outhouse is common in secondary-school and first-year university syllabi. It links to neighbouring topics Appropriate technology, Toilets, Wooden buildings and structures, so understanding it makes those chapters shorter.
In everyday life
Look for Outhouse outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
