ARRANGEMENTS FOR SEQUITABLE WATER SELECTIONS: 1 water abstraction; 2 pumping stations for the first rise of water; 3 septic tanks; 4 filters; 5 chlorinatorial; 6 water tanks; 7 water pumping stations for the second rise; 8 water wells; 9 water pumping towers for the discharge of water from the underground water well: 1 artesian well; 2 pumping stations for the first rise of water; 3 water tanks; 4 pump stations for the second rise of water; 5 pipelines; 6 water pipes from which water flows into the water network of the built-up area

LAUGHTER SYSTEMS: (a) In the case of a constant (satisfying) pressure b — in the case of a periodic pressure with a water tank in — in the case of a periodic pressure with a pump g — in the case of a continuous lack of pressure, MULTIZONAL SYSTEMS: (d) in the case of the supply of water by a single pipe to all areas from one pump station e — in the case of a steady supply of water g — in the case of the parallel supply of water 1 — parking points 2 — shut-off fixtures 3 — routes 4 — descent crane 5 — water meter 6 — pump 7 — non-return valve 8 — water tank

1 — Washing machine 2 — water thinner 3 — water thinner 4 — cold water collector 5 — hot water collector 6 — non-return valves 7 — hot water counter 8 — cold water counter 9 — pressure adjusters 10 — rough cleaning filters 11 — cut-off cranes 12 — hot and cold water freezers

Sprinkler systems respond to changes in the ambient parameters of an object with a high fire risk. Drenchers are activated automatically or manually, allowing fires to be put out immediately for large areas. The second type of system may be used for low temperature spaces, as the water in the pipes is supplied after the control signal. The drenching system is activated almost immediately, while the springclairs require time to destroy the thermally controlled bulb or lock.

In the Orkney Islands (Scotland), 3,000 B.C.E., houses were provided with special drips to address the needs associated with sewage gutters. In Pakistan, a drainage system is used in the Mohenjo Daro settlement in the Indus region, where the sewage from each house falls into a common ditch. On the island of Bahrain, the first flush toilet of the 69th type was discovered in the Persian Gulf. A tax on toilets of 1214 is first introduced in the Ottoman (Tureška) Empire. Public toilets of 1596 are being introduced in Europe. John Harrington invents waterclothes of 1669. A police decree is being issued in Paris ordering the construction of separate toilets for men and women in the 1739s. In Paris, separate toilets for men and women are being built. The first public toilet is opened in Paris in 1883. For Queen Victoria, the first ceramic toilet of 1959 is being manufactured in Paris.

In Milan, Leonardo da Vinci was responsible for the construction of the city ' s sewage system, and the contemporaries observed the cleanness of the city, as underground ditches were laid beneath every street, in which runoff and sewage came through special holes in the stone plates with a bridge. When, at the invitation of French King Francis I Leonardo, he arrived in Paris and was so shocked by the stench of Paris that in 1516, he designed a toilet that was washed away for his patron. In the drawings of the great seer, both the water pipes, the water pipes, the vents, and the vents, and the valve for the regulation of the discharge water, and even the toilet lid, which was intended to limit the introduction of unpleasant odour into the room. Unfortunately, Leonardo’s ideas were still on paper. Francis, who had honored Da Vinci, did not want to build his image, as it would have required running water and sewers, which cost a lot of money. In addition, he already had a throne toilet, a subject of envy and the role of many chiefs.

The first revolution was by Scottish mechanic and watchmaker Alexander Cummings, who in 1775 obtained a British patent for a discharge hole filler and an S-shaped tube (water shutter) that prevented odor from entering the premises. After three years, the system was improved by the mechanic Joseph Brahm (the future inventor of the hydraulic press), who offered a flap and developed a float system for Queen Victoria’s Board of Directors as a golden age for British plumbers. In 1852, George Jennings built a cup with a valve, which only opened for the time of flushing under the weight of water, and the rest of the time effectively covered the discharge hole. In the 1870s, the plumber and entrepreneur Thomas Krepper proposed to raise the plumber to the ceiling to increase the pressure of water, and to extend the chain of handle to the lever. He also completely abandoned the mechanical latches and flaps in favour of the water shutter and for the first time used the syphonic system extensively instead of constantly running float valves. In 1883, Thomas Twiford introduced his masterpiece, a single design of a bowl and a water lock, not of metal, but of a much more aesthetic and sanitary fayance. An aggregate called Unatas (translated from Latin «Unity») was equipped with an upper barrel of Krepper’s structure, as well as a lifting wooden seat. This masterpiece was the real star of the 1884 international exhibition on health in London. It is this model that shaped the modern toilet and, according to one version, gave it a name (there is another version — it is alleged that the name of the toilet was derived from the name of the Spanish company Unitas, which supplied waterclothes to Russia). < https://www.popmech.ru/diy/10394-unitaz-izobretenie-tysyacheletia-bez-schutok/ >
