July 5, 2013: Tel Aviv Water War

July 5, 2013:  Every summer the city of Tel Aviv cools off with a big water fight: the Tel Aviv Water War. 2013 was the ninth year that this event has taken place, and each year it gets bigger and better with thousands of residents and visitors taking part in the unique event in Kikar Rabin in the center of town. In a weird way, the stability and consistency of the water war, has stood as an annual tradition amid an ever-changing world, and ever-changing region! The 2013 Tel Aviv Water War took place on Friday July 5, 2013 at 3:15pm. In 2014, the water war took place on July 4.

The Tel Aviv Water War is of course, free to enter. Be sure to bring your best beach clothes. The Tel Aviv Water War is a totally unique Tel Aviv event! It couldn’t happen anywhere else in the world like it does here!



On February 1, I tried a new posting system for this blog and it resulted in the folks following me and expecting email delivery to not get their deliveries. I apologize for the mistake and confusion this has caused. I will be going back to the old blog publishing system tomorrow, March 12. Many thanks to all of my faithful readers.

November 28, 1837: Birth of John Wesley Hyatt.

1128 John W HyattNovember 28, 1837: Birth of John Wesley Hyatt. Hyatt was an inventor who developed new materials and machines that resulted in hundreds of patents. He is mostly known for his invention of a commercially viable way of producing solid, stable nitrocellulose, which he patented in the United States in 1869 as “Celluloid.” However, he was one of the early developers of commercial filtration systems in the U.S. He invented improvements to mechanical filtration systems, which are called rapid sand filters or granular media filters today. During the 1880s, mechanical filters were installed to remove particles and “organic matter.” Filtration to control microbial pathogens would come later with better bacteriological methods and the maturation of the germ theory of disease.

“John Hyatt, an inventor and manufacturer of Newark, N.J., applied for a patent February 11, 1881, on what was virtually a stack of Clark’s filters, placed in a closed tank and operated each independently of the others by means of common supply, delivery and wash pipes. His application, like Clark’s, was granted on June 21, 1881, and assigned to the Newark Filtering Co. On the same day, Hyatt obtained a patent in England.

Col. L. H. Gardner, Superintendent of the New Orleans Water Co., after making small-scale experiments on coagulation at New Orleans, was convinced that it was more efficacious than filtration for the clarification of muddy water.

Isaiah Smith Hyatt, older brother of John, while acting as sales agent for the Newark Filtering Co., was baffled in attempts to clarify Mississippi River water for a New Orleans industrial plant. Colonel Gardner suggested using a coagulant. This was a success. Isaiah Hyatt obtained on February 19, 1884, a patent on simultaneous coagulation-filtration. Although unsound in principle, it largely dominated mechanical filtration for many years….

Thus in 1880-85 did four men join in the evolution of mechanical or rapid filtration. Clark soon faded out of the picture. Gardner entered it only by suggesting to Isaiah Hyatt the use of a coagulant, and Isaiah Hyatt, still a young man, died in March 1885. John Hyatt was then alone. Already he had taken out 20 filter patents while only two were granted to his older brother. By the close of 1889, John had obtained about 50 patents. Scattered grants in the 1890’s brought his record above 60. Most notable of all these were three on washing systems, including sectional wash; several on strainers for underdrain systems; and two on aeration, primarily in connection with filtration. The Hyatt aeration patents, like those granted to Professor Albert R. Leeds a little earlier, were of little practical importance, but they marked an era in water purification during which stress was laid on the removal of organic matter.”

November 14, 1765: Death of Robert Fulton; 1840: Birth of Claude Monet; 1919: Death of John Aitken

1114 Robert FultonNovember 14, 1765: Today in Science History. Robert Fulton–Born 14 Nov 1765; died 24 Feb 1815 at age 49. “American inventor, engineer, and artist who brought steamboating from the experimental stage to commercial success. He did not invent the steamboat, which had been built in the early 1700’s, but rather applied his engineering skills to their design. He changed the proportions, arrangements, and velocities of already proposed ideas. In 1807, work was completed on the Clermont, the first steamboat that was truly successful, and the culmination of many years of work. It’s maiden voyage was on 17 Aug from New York City to Albany, a distance of 150 miles completed in 32 hours. A mechanical genius with many talents, he also designed a system of inland waterways, a submarine (Nautilus, 1801), and a steam warship.”

1114 Water LiliesNovember 14, 1840: “Claude Monet (14 November 1840 – 5 December 1926) is born. He was a founder of French impressionist painting, and the most consistent and prolific practitioner of the movement’s philosophy of expressing one’s perceptions before nature, especially as applied to plein-air landscape painting…. Monet was fond of painting controlled nature: his own gardens in Giverny, with its water lilies, pond, and bridge. He also painted up and down the banks of the Seine, producing paintings such as Break-up of the ice on the Seine.” Perhaps Monet’s most famous series of paintings is his Water Lilies.

1114 John AitkenNovember 14, 1919: Today in Science History. John Aitken died. (born 18 Sep 1839) “Scottish physicist and meteorologist known for his research work on atmospheric dust, the formation of dew, cyclones and evaporation. He invented the koniscope to detect and study atmospheric dust particles. He determined that condensation of atmospheric water vapor from clouds and fogs begins on the surface of microscopic particles (now known as Aitken nuclei) as a crucial step in the formation of rain and dew. Combustion produces a profusion of such particles. Suffering from ill health, he worked from a laboratory in his Falkirk home.”

October 14, 1842: Croton Water Celebration; 1862: Mixing Water with Milk; 1859: Dedication of Glasgow Water Supply

1014 Croton celebrationOctober 14, 1842: Celebration of the delivery of the Croton water supply to New York City. “Two days before the holiday Hone wrote in his diary: ‘Nothing is talked of or thought of in New York but Croton water; fountains, aqueducts, hydrants, and hose attract our attention and impede our progress through the streets. Political spouting has given place to water spouts, and the free current of water has diverted the attention of the people from the vexed questions of the confused state of the national currency.’

The great day began with the discharge of one hundred cannon and the ringing of church bells. Thousands of jubilant spectators crowded the windows, balconies, and sidewalks to watch a five-mile-long parade pass by. First came an impressive military escort, then a dozen barouches bearing Governor Seward, Mayor Morris, Samuel Stevens, Stephen Allen, Philip Hone, and other dignitaries. These were followed by regiments of soldiers, by fifty-two companies of firemen with bright uniforms, banners, and well-polished machines, by the butchers on horseback, by numerous marching temperance societies, and by organizations of mechanics….

The fountains were a special delight. Of one erected in Union Square, a contemporary newspaper declared: ‘It throws up a noble column of water to a height as great almost as the houses which surround the square …. In the evening, by the moonlight, the effect of the fountain showering its spray on every side, was exceedingly fine.’”

Commentary: They really knew how to celebrate a new water supply back then. Can you imagine a salute of 100 cannons for delivering State Project water to Southern California in the 1960s? How about we shoot off the cannons when the desalination plant at Carlsbad, CA is operational?

1014 Baby drinking milk from bottleOctober 14, 1862:  New York Times headline–Mixing of Water with Milk Not an Adulteration. “The People ex rel. Jacob Fauerbach vs. Court of Sessions. — The relator was convicted in the Court of Sessions of vending adulterated milk, and sentenced to pay a fine of $55.

He appealed the case to the New York Supreme Court, contending that the act under which he was convicted was purely a sanitary measure, intending to prevent traffic in impure, diseased and unwholesome milk, and not to prevent fraud in the sale of diluted milk. That to put water into milk was not to corrupt it, according to dictionary definition. Water was not a foreign admixture of milk, but its chief ingredient in its natural state, and it could not be adulterated by adding a little more.

The Court, in an opinion by Justice Ingraham, have now reversed the decision of the Judge at the General Sessions, upon the ground that to put water in milk is not per se such an adulteration as necessarily brings the relator within the late law upon that subject.” Commentary: Adding water to milk to increase profits was a common occurrence in the latter half of the 19th century. The problem was that most of the drinking water in cities during this period was laced with pathogenic organisms. The death of infants before one year of age in U.S. cities from diarrheal diseases was 20% to 40% of live births (that is not a misprint). Diluting cow’s milk with contaminated water was one of the chief means of killing babies. The judges did not help matters by overturning this crook’s conviction.

Glasgow Waterworks—Loch Katrine Outlet, 1859: antique wood engraved print

October 14, 1859:  Dedication of the Loch Katrine Water Works for the City of Glasgow, Scotland, by Queen Victoria. “It is with no ordinary feelings of pride and satisfaction that we are enabled this day to state to your Majesty that we have completed one of the most interesting and difficult works of engineering, and, at the same time, the largest and most comprehensive scheme for the supply of water which has yet been accomplished in your Majesty’s dominions. The deficient and unsatisfactory condition of the water supply, on which so much of the health and comfort of the inhabitants depended, determined the Corporation of Glasgow, some years ago, to purchase the works of the Water Companies then existing, and to take the supply of water into their own hands. For this purpose an Act of Parliament was obtained, which received your Majesty’s royal assent on the 2d day of July, 1855. Empowered by this Act, the Commissioners came to these wild and romantic regions for that copious supply of pure water of which the large and rapidly increasing population of Glasgow stood in need. This beautiful and extensive loch of pure water, fed by a large amount of annual rainfall, and lying at an elevation of 360 feet above the sea, was selected as the fountain-head. The rugged district, of 34 miles in extent, which intervenes between the loch and the city, has been penetrated by tunnels, crossed by aqueducts, or traversed by iron pipes, in the execution of the necessary works for ultimately conveying to the city no less than 50,000,000 gallons of water per day.”

October 25, 1949: Patent issued on ductile iron pipe; 1848: Lake Cochituate water delivered to Boston; San Antonio Water Company incorporated; 1987: Sewers below Paris.

1025 Ductile Iron PipeOctober 25, 1949: Patent issued on Ductile Iron pipe. On this day, patent Number 2,485,761 was issued to Mr. K. D. Millis and others of the International Nickel Company, for “Gray Cast Iron having Improved Properties.” It has since become known as ductile iron.   Gray iron becomes ductile iron through the inoculation of the molten mix with magnesium, changing the graphitic carbon from random flake forms into a more geometrically arrayed and spherical form. The new matrix provides greater yield strength, ultimate strength, and elongation properties.

Cast iron pipe producers had raced International Nickel to the patent office, but International Nickel got there first. Cast iron pipe producers soon began the commercial production of ductile iron pipe, which has supplanted cast iron due to its greater strength and toughness. Cast iron and ductile iron pipes form the backbone of America’s drinking water distribution systems.

Lake Cochituate Dam

Lake Cochituate Dam

October 25, 1848: First delivery of water from Lake Cochituate into Boston. “Lake Cochituate was created by the construction of Lake Cochituate Dam to provide a reservoir for water supply to the City of Boston, via the 14-mile Cochituate Aqueduct. Lake Cochituate was the first major water supply system built for the city, and replaced the previous usage of Jamaica Pond. Developed from 1848 to 1863, it supplied Boston’s water until 1951, when the larger Wachusett and Quabbin Reservoirs replaced it. The surveys and plans for the project were performed by American civil engineer James Fowle Baldwin (1782–1862), the son of Loammi Baldwin who designed the Middlesex Canal, and younger brother of Loammi Baldwin, Jr. (1780–1838) who authored the earlier studies for a Boston water supply. The dam, located on the lake’s former northwestern outlet, formed the headworks of the water supply system, and is now listed on the National Register of Historic Places.”

1025 San Antonio Water CompanyOctober 25, 1882San Antonio (California) Water Company, Mutual Water Company, incorporated; natural waters of area part of ‘The Cucamonga Rancho’, 1839 land grant, portion of original territory granted to San Gabriel Mission; statement of purpose: “Acquiring by appropriation, purchase, or otherwise, water, water rights, water privileges and right of way in the Counties of Los Angeles and San Bernardino and to furnish, lease or sell the same for irrigation, milling, manufacturing and other purposes. To own, hold, construct and maintain canals, ditches and all structures, lands, easements and rights appertaining thereto for the purpose of taking and conveying water as herein mentioned to owners of lots and blocks in the Village of Ontario and to stockholders in this Corporation and none others. To make improvements, borrow money and transact any and all business and things connected with the business of the Corporation and relating thereto”; development of water rights, delivery services initiated as migration of people resulted in development of agriculture, business, residency; 1890s – irrigation by Zanjeros (ditch walkers; derived from Spanish words “zanja”, meaning “deep ditch or irrigation ditch”, and “zanjon”, which means, “ditch rider or overseer”; employees who constructed acequias (canals) to provide controlled, dependable water supply to farmers; gave way to automated systems.

1025 Paris SewersOctober 25, 1987: New York Times headline–The Worlds Beneath Paris. “The great historian of the Paris sewers was, of course, Victor Hugo, who not only has his hero Jean Valjean escape the authorities through the sewers, carrying the wounded Marius Pontmercy on his back, but who also devotes six chapters of ‘Les Miserables’ to a history of the sewers and their peculiarities and dangers. Paris, Hugo wrote, ‘has another Paris under herself: a Paris of sewers, which has its streets, its crossroads, its squares, its blind alleys, its arteries, and its circulation . . . .’

By the time he wrote these words (the book was published in 1862) the city’s ancient sewer system had been considerably modernized. It has been continuously and ingeniously improved since then so that today a 1,305-mile network of canals – one so extensive that if straightened it would reach to Istanbul – carries off, treats and returns to the Seine the city’s daily discharge within the span of a single day. If in a sunny street you have ever paused to wonder at the primitive-seeming phenomenon of Parisian street-cleaning, the gurgling gutter waters directed this way and that by bundles of rags, down here you learn just how sophisticated waste disposal really is.

The tour begins with the smell, which no amount of cleansing can quite eradicate. But once into the small, well-done Musee des Egouts you quickly forget it. Here in documents, engravings, photos, diagrams and models of machinery is a short course in the evolution of the sewer system from the time when chamberpots were dumped into the streets to the present gravity-flow system whose complex network is shown in a map.”

Commentary:  I have crawled through my share of sanitary sewers and there is no way that any museum will ever help me forget the smell.
