Today I would like to take the entire toilet thing to a new level. We have spoken about female toilets in my last blog – but have you ever given the men’s urinal any thought?
Coming from a man – the urinal is probably the single closest object that take man back to his caveman days – The main differential being – we actually stand in front of a porcelain object instead of a tree.
A urinal is a specialized toilet for urinating into generally used by males. It has the form of a container or simply a wall, with drainage and automatic or manual flushing.
The different types of urinal, for single or multiple users in trough style designs are intended to be utilized from a standing position- probably to remind us men about the time we where cavemen.
Public urinals often contain a deodorizing urinal deodorizer block contained within a plastic mesh guard container or a plastic mesh guard without a urinal cake. The plastic mesh guard is designed to prevent solid objects (such as cigarette butts, feces, chewing gum, or other objects) from being flushed and possibly causing a plumbing stoppage.
Purposes
In busy men’s washrooms, urinals are installed for efficiency: compared with urination in a general toilet, usage is faster because within the room there are no additional doors, no locks, and no seat to turn up; also a urinal takes less space, is simpler, and consumes less water per flush than a toilet. Urinals also come in different heights, which help for those who might be very tall or very short (here I refer to the distance your winkie is from the floor). Often there are barriers dividing the urinals, which add to privacy.
Flushing
Most public urinals incorporate a flushing system to rinse urine from the bowl of the device to prevent foul odors. The flush can be triggered by one of several methods:
Manual handles
This type of flush might be regarded as standard. Each urinal is equipped with a button or short lever to activate the flush, with users expected to operate it as they leave. Such a directly-controlled system is considered the most efficient provided that patrons remember to use it. This is far from certain, however, often because of fear of touching the handle, which is located too high to kick. Urinals with foot-activated flushing systems are sometimes found in high-traffic areas; these systems have a button set into the floor or a pedal on the wall at ankle height. The Americans with Disabilities Act requires that flush valves be mounted no higher than 44 in. AFF (above the finished floor). Additionally, the urinal shall be mounted no higher than 17 in. AFF, which has a rim that is tapered and elongated and protrudes at least 14 in. from the wall. This enables users in wheelchairs to straddle the lip of the urinal and urinate without having to “arc” the flow of urine too high and because it’s a rest
Timed flush
In Europe, manual flush handles are unusual. Instead, the traditional system is a timed flush that operates automatically at regular intervals. Groups of up to ten or so urinals will be connected to a single overhead cistern, which contains the timing mechanism. A constant drip-feed of water slowly fills the cistern, until a tripping point is reached, the valve opens (or a siphon begins to drain the cistern), and all the urinals in the group are flushed. Electronic controllers performing the same function are also used.
This system does not require any action from its users, but it is wasteful of water where the toilets are used irregularly. However, in these countries men are so used to the automatic system; attempts to install manual flushes to save water are generally unsuccessful. Users ignore these not because of deliberate laziness or fear of infection, but because activating the flush is not habitual.
To help reduce water usage when restrooms are closed, some restrooms with timed flushing use an electric water valve connected to the restroom light switch. When the building is in active use during the day and the lights are on, the timed flush operates normally. At night when the building is closed, the lights are turned off and the flushing action stops.
A flushing system connected to the opening of the washroom door can count the number of users and operate when the count reaches a certain value. At night, the door never opens, so flushing never occurs.
Automatic flush
Electronic automatic flushes solve the problems of both previous approaches, and are common in new installations. Active or (more usually) passive infrared sensors identify when the urinal has been used (or when someone has stood in front of it and moved away), and activate the flush. Thus the urinal is cleaned, where with a manual flush it might not have been, but water is not wasted when the toilet is not used.
Automatic flush facilities can be retrofitted to existing systems. The handle-operated valves of a manual system can be replaced with a suitably-designed self-contained electronic valve, often battery-powered to avoid the need to add cables. Timed-flush installations may add a device that regulates the water flow to the cistern according to the overall activity detected in the room. This does not provide true per-fixture automatic flushing, but is simple and cheap to add because only one device is required for the whole system.
To prevent false-triggering of the automatic flush, most infra-red detectors require that a presence be detected for at least five seconds, such as when a person is standing in front of it. This prevents a whole line of automatic flush units from triggering in series if someone just walks past them.
The automatic flush mechanism also typically waits for the presence to go out of sensor range before flushing. This reduces water usage, compared to a sensor that would trigger a continuous flushing action all the while a presence is being detected.
Door-regulated flush
This is an older method of water-saving automatic flushing, which only operates when the room is being used. A push-button switch is mounted in the door frame of the restroom, and triggers the flush valve for all restroom urinals every time the door is opened. While it can’t detect the use of individual urinals, it provides reasonable flushing action without wasting excessive amounts of water when the restroom is not being used. This method requires a spring-operated automatic door closer, since the flush mechanism only operates when the restroom door opens.
Waterless urinals
A more recent innovation is urinals that use no water at all. The innovation is secured with several patents. Models later introduced, utilize a trap insert filled with a sealant liquid instead of water. The lighter-than-water sealant floats on top of the urine collected in the U-bend, preventing odors from being released into the air. Although the cartridge and sealant must be periodically replaced, boosters claim the system saves anywhere between 55,000 and 170,000 liters of water per urinal per year.
Other companies do not use a cartridge; instead they have developed an outlet system that traps the odor, preventing the smell often present in toilet blocks. Another method to eliminate odor was introduced a deodorizing block in their waterless urinal that was activated during use. Waterless urinals can be installed in high-traffic facilities and in situations where providing a water supply may be difficult or where water conservation is desired.
Most waterless urinals however do not remove odor staining on the surface of the urinals, if not normally cleaned. Even when maintained according to recommendations, flush-free urinals emit a fish-like odor that most people find unpleasant. In February, 2010, the headquarters of the California EPA removed waterless urinals that were installed in 2003 due to “hundreds of complaints” including odors and splashed urine on the floors.
Arrangement of urinals
Urinals in high capacity men’s washrooms are usually arranged in one or more rows. In men’s bathrooms, the urinals are usually placed directly opposite the door, so that men have their back to those who enter or stand outside. Those in the street may come in sets arranged in a circle, with all men facing the center, with screens high enough that men cannot wet each other, and usually high enough that they cannot see over it. In a street urinal with an outside screen or wall, the men may stand back to back.
Urinals used in a high throughput capacity area are part of efficiently designed washroom architecture. Large numbers of them are usually installed along a common supply pipe and drain. There may be partitions for privacy.
Often, one or two of the urinals, typically at one end of a long row of urinals, will be mounted lower than the others; they are meant for young boys and other males who cannot reach the regular urinals. In facilities where males of various heights are present, such as schools, urinals that extend down to floor level may be used to allow anyone of any height to use any urinal. In other bathrooms, trough urinals are placed, which most of the time can hold large numbers of men and boys.
Once used exclusively in commercial or institutional washrooms, urinals for private home installation are now available. They offer the advantage of substantial savings of water in homes with multiple male occupants.
Street urinals and vespasiennes
In some localities, urinals may be located on public sidewalks or in public areas such as parks. These urinals are usually equipped with partitions for the sake of privacy. They may or may not be equipped with flush mechanisms.
A city famous for its street urinals is Paris, France. Until the 1990s, street urinals were a common sight in the city, and in the 1930s more than 1200 were in service. Parisians referred to them as vespasiennes, the name being derived from that of the Roman Emperor Vespasian, who, according to an anecdote, imposed a tax on urine. Beginning in the 1990s, the vespasiennes (renowned for their smell and lack of hygiene) were gradually replaced by Sanisettes. Today only one vespasienne remains in the city (on the boulevard Arago), and it is still regularly used. They still exist in other French cities, and in other countries. The Netherlands has a number of strategically-placed street pissoirs in various cities.
In the Philippines, Marikina city was the first city to install street urinals in the late 1990s. When the Marikina mayor Bayani Fernando was appointed chair of the Metropolitan Manila Development Authority, he installed street urinals in the rest of the capital as well.
Makeshift urinals
During the Korean War, Vietnam War, Operation Desert Storm etc., “piss tubes” were used as makeshift urinals. To make one, soldiers would affix an inverted water bottle on one end of a rigid tube, burying the other end. Removing the base of the bottle made a funnel which would be left at the proper height. Deposited urine simply soaked into the ground. When the area became saturated, the device was relocated.
Urinals for women
Nearly all urinals are intended for use by males, but a few have been designed for use by women. From 1950 to 1974, the American Standard company offered the mass-produced “Ladies’ Home Urinal”. It did not provide significant advantages over conventional toilets, because it used just as much floor space and flushing water. Its main selling point was that women could use the fixture without touching it.
Several other designs have been tried since then, but they either required the user to hover awkwardly or to bring her genitals into close contact with the fixture. Most have not caught on. Current clothes fashion such as panty hose and slacks inhibit women from using them because they do not want their garments to touch the urinals or the floor. Often, women have little experience with them and do not know whether to approach them forward or backward.
More recently, models that use specialized funnels have been introduced, with some success, at outdoor festivals such as Glastonbury (to reduce cycle times and alleviate long lines).
So you thought you knew everything about taking a leak?
The flush of a urinal either mechanically or automated is equally disturbing and can easily be equated the toilet sneeze of a toilet bowl distributing fine droplets of faecal matter, human body fluids and pathogens in the same manner.
Then there is the strange phenomenon that only man can manage – picture this – there is this beautiful porcelain vase like devise mounted on the wall designed as a catchment area for urine the height, width and depth of the collection area is totally disproportionate to the size of mans penis yet by some incredible manner man seems to distribute a substantial volume of urine onto the floor.
Now is this because the penis is to short or is it that man does not stand close enough. (Tough one)
If man stands to close then there is the possibility of back-slash and your trousers get splashed and every one outside of the restroom knows what you have done – oh so embarrassing. If you stand a bit further back you stand the risk of splashing on your shoes and on the tiles. Now the shoe part is not that bad but urine on the tiled floor presents a total different janitorial problem. Urine seeps into the cement grouting between the tiles and deposits itself under the tile. This is where most of the foul stale urine odour emerges from and no known chemical can get there to eradicate this stench.
There are ways to remedy this odour by using a biological product that eliminates such organic matter. (You may wish to visit our website and learn more about the products designed to eliminate odour)
Then there is the risk of contaminating other areas within the bathroom i.e. the basin tap – you have just touched yourself, a bit of spray back has contaminated your hand or hands (big boy) and God forbid that you have actually remembered to flush as you do – you have touched the button or lever.
If you do decide to wash your hands – how many people that have experienced the same as you have touched the tap? The big question – do I wash my hands or not?
And you thought you were just going to have a leak – this is so complicated – perhaps we need to resort back to the caveman – find a tree and pee against it.
