#TDIWH—February 28, 1895: Los Angeles Sewer System

0228 LA Sewer system aFebruary 28, 1895: Engineering News article. The Sewerage System of Los Angeles, Cal. by Burr Bassell. “The City of Los Angeles is built upon both sides of a torrential stream, called the Los Angeles River, at a point 20 miles from its mouth. The corporate limits of the city may be described as a square, more than five miles on a side, containing 18,597 acres….

The present river channel is dependent upon artificial means for the confinement of its waters. Its bed is 30 ft. higher at the point where it leaves the south charter boundary, than at the southwest corner of the city. This change of channel is probably due to the influence of a tributary, called the Arroyo Seco, which empties its storm-waters laden with sand, gravel and boulders from the mountains on the north into the very center of the city….

The census of 1880 gave a population of 11,183, that of 1890, 50,395. A conservative estimate for 1894 is 70,000.

The first comprehensive plan for sewering the city was prepared in 1887 by Mr. Fred Eaton, M. Am. Soc. C. E., at the time city surveyor. It was designed on the separate system, with an outfall sewer to the sea, via the Centinela Rancho. His estimated cost of the internal system was $533,846, and for an outfall sewer to the ocean by the Centinela route, 11.5 miles in length, $466,154, making a total of $1,000,000.

Mr. Rudolph Hering, M. Am. Soc. C. E., reported favorably on Mr. Eaton’s plans, and stated that the problem of designing a good sewerage system for the city presented no serious difficulties.

Reference: Bassell, Burr, 1895. “The Sewerage System of Los Angeles, Cal.” Engineering News. 33:9(February 28, 1895): 139.

Commentary: This article is remarkable in so many ways. Los Angeles was only 25 square miles and the population was only 70,000! Obviously, the city has grown a bit since the article was written. Incidentally, the article goes on at length to describe other sewering options. The plot plan below represented the preferred option. As near as I can tell, the outfall for this sewer is right about where the Los Angeles International Airport (LAX) is now located.

Mr. Fred Eaton went on to play an infamous role in Los Angeles water wars. In 1905, Eaton was a central character in the purchase of the Owens Valley lands that formed the basis for the Los Angeles water supply imported from the Eastern Sierras. Eaton’s actions were conducted under the inappropriate cloak of respectability of the U.S. Reclamation Service which has caused hard feelings in the region for the past 109 years. Rudolph Hering played a role in this project. He has been portrayed many times in this blog including two days ago when we celebrated the anniversary of his birth.

#TDIWH—February 27, 1913: Croton Chlorination Plant

0227 Croton Cl2 plantcFebruary 27, 1913: Engineering News article. Chlorinating Plants, Croton Water Supply. “Synopsis—Operating results of a temporary plant, which treated with hypochlorite of lime more than 100 billion gallons of Croton water for New York City in 1912, are given. A permanent hypochlorite or chlorinating plant, to treat the flow through both the old and the new Croton aqueducts, is described and fully illustrated. Brief descriptions are given of four other chlorination plants in the Croton drainage area: Three to treat the waters of tributaries of the Croton before it reaches the main supply and one to treat another tributary and a part of the sewage of the village of Brewster, N. Y.”

In June, 1910, I. M. de Varona, chief engineer of the Department of Water Supply, Gas and Electricity of the City of New York, made trials of hypochlorite treatment in connection with the Croton water-supply. The results were so satisfactory that its use has been extended until the city now maintains five of these plants: one on the New Aqueduct at Pocantico, treating the entire supply from the Croton, and the other four upon various tributaries of the reservoirs.

The continuous treatment of the flow of the New Croton Aqueduct was commenced in June, 1911, the plant being located at Shaft No. 9, north of Tarrytown, N. Y., known as the Pocantico plant. It consists of a rough frame building which houses two cement-lined cypress tanks, 12 ft. in diameter and 6 ft. in height, and a constant-level feeding tank with adjustable orifice discharging through a manhole into the crown of the aqueduct. Within the aqueduct, there is suspended a wooden grid to secure a proper mixture of the chlorine solution and the flowing water. The operating floor is just above the solution tanks and in it are two screened mixing pits.

In operation, a drum of lime, weighing about 800 lb., is rolled into position over a pit and the contents washed out into the pit by a hose stream under pressure. Enough ‘bleach’ is dissolved to treat the aqueduct flow for 12 hours. The tank is then filled with water and stirred to assure the thorough absorption of the chlorine. Four men operate the plant, two on the clay shift, making solution, and one on each of the night shifts, maintaining a constant, uniform flow of the solution.

0227 Croton Cl2 plantbExperience has shown the desirable amount of chlorine to be between 0.40 and 0.65 p.p.m. (parts per million). The lower amount is used in warm weather and when Croton Lake is near the high water line. The amount is gradually increased as the storage in Croton Lake drops or the temperature of the water approaches freezing. The amount of ‘bleach’ to be used daily is determined from a chart (Fig. 1), which shows that the daily amount of chemical is about 4000 lb. Where so much chemical is used, the chart shows the economy resulting from varying the charge of ‘bleach’ in accordance with the amount of its available chlorine, as determined by laboratory analysis.”

Commentary: New York City began testing chloride of lime to disinfect the Croton water supply shortly after the findings of the special master in the second Jersey City trial which has been described at length in The Chlorine Revolution: Water Disinfection and the Fight to Save Lives.

#TDIWH—February 26, 1847: Birth of Rudolph Hering

Rudolph Hering

Rudolph Hering

February 26, 1847: Rudolph Hering was born. “Although Dr. Hering was one of the first to recommend mechanical filters for pumping the water supplies at Atlanta, and elsewhere, and was connected with important water supply investigations at New York, Philadelphia, Washington, New Orleans, Columbus, Montreal, Minneapolis and numerous smaller places, his accomplishments were greatest in the field of sewerage and sewage disposal and led to his having been designated years ago as the ‘Dean of Sanitary Engineering” in this country. Recognition of such standing was perhaps first made by President Harrison, who, in 1889, appointed him Chairman of a Commission to prepare a program for sewerage improvements for Washington, D. C.

Dr. Hering was an active worker on the committees of various professional organizations as well as civic movements. His most important work was undoubtedly that for the American Public Health Association in the matter of the collection and disposal of refuse. He gathered statistics as to results of operation and otherwise elucidated practice in this country and Europe. Some twenty-five years ago he gave liberally of his own time and money for gathering information upon this subject, although his activities in the field of water supply and sewerage did not permit him to publish the results of his investigations in the disposal of solid wastes of the municipalities.

Dr. Hering was in partnership with George W. Fuller, M. Am. Soc. C. E., from 1901 to 1911 and with John H. Gregory, M. Am. Soc. C. E., from 1911 to 1915. After the latter date his activities were confined largely to work upon a book on ‘Collection and Disposal of Refuse’ of which he was a joint author with Samuel A. Greeley, M. Am. Soc. C. E….

He received an honorary degree of Doctor of Science from the University of Pennsylvania in 1907, and an honorary degree of Doctor of Engineering from the Polytechnic Institute at Dresden in 1922. He was a member of a large number of engineering societies both in this country and in Europe. He was an honorary member of the New England Water Works Association and of the American Water Works Association and a Past President of the American Public Health Association. He became a member of the American Society of Civil Engineers in 1876, was Director in 1891, 1897 to 1899, and Vice President in 1900 to 1901.”

#TDIWH—February 25, 1910: Chlorine Disinfection in Minneapolis

The East Side Pumping Station was built on Hennepin Island in 1885 and efficiently delivered sewage-contaminated drinking water to Minneapolis

The East Side Pumping Station was built on Hennepin Island in 1885 and efficiently delivered sewage-contaminated drinking water to Minneapolis

February 25, 1910: The first use of chlorine as a drinking water disinfectant in Minneapolis, MN. “The water source for Minneapolis, Minnesota, in 1910 was the Mississippi River. At that time, the city had a population of about 380,000, and average daily water use was about 20 mgd. Water was pumped from the river into two rectangular basins with a total capacity of 97 million gallons. Plagued with outbreaks of typhoid fever, the city had considered several treatment options including the installation of slow sand filters. However, none of these plans came to fruition because of the resistance of the electorate and the costs of the projects. On February 25, 1910, a chloride of lime treatment system was put into operation after an alarming increase in typhoid cases and deaths in the city.”

#TDIWH—February 24, 1953: Birth of Pat Mulroy; 1815: Death of Robert Fulton

0224 Pat MulroyFebruary 24, 1953: Pat Mulroy was born. Patricia Mulroy is the general manager of the Southern Nevada Water Authority. Her job is to make sure that Las Vegas and the surrounding metropolitan area has enough water, now and in the future. Mulroy is the German-born daughter of an American father and a German mother. She was hired in 1978 when she was working for the University of Las Vegas to work in an administrative job at the Las Vegas Valley Water District. She became general manager of that organization in 1989 and in 1991 she was chosen as the general manage of the newly formed Southern Nevada Water Authority.

Because Las Vegas has one of the lowest priorities of water rights on the Colorado River, her tenure has been marked by some of the most innovative efforts to increase the region’s water supply and revolutionary ideas to conserve water. She has gone way beyond the usual approaches of low flow showerheads and low flush toilets. The Authority’s program to buy back turf grass in people’s yards at a price of up to two dollars a square foot has been called by some as a historic turning point in the war against municipal water over-use in the arid West.

She has been called ruthless, scheming and tough. And those are some of the nice things that people who have gone up against her say about her. She is also scary smart and not afraid to take on the biggest and the baddest opponents to get what she wants. And what she wants is what is best for the Authority and the people served by it. Some people say that she has mellowed over the years and is now approaching the task of squeezing more water out of a drought-stricken Colorado River with a more strategic approach.

“Her preferred strategy now [2010] is to weight it [Colorado River water rights] down with subsequent agreements so numerous that the contract is in effect suffocated. In her words, ‘Put enough agreements on top of it that it becomes meaningless.’ While her style remains blunt and no-nonsense, her grasp of the realpolitik of the Colorado River water users has grown more sure and subtle. She is a deal maker when necessary, looking to expand the possibilities for trading water rights or to provide incentives for others to compromise. She infuriated residents of northeastern Nevada and western Utah by pushing for a 285-mile pipeline to bring groundwater from the Snake Valley to Las Vegas but eventually struck a deal, although resentment remains and Utah is not yet formally on board.” (Barringer 2010)

Pat Mulroy is one of a kind. She has shaken up the good-old-boys network of water resources experts in the Western U.S. and we are all better off because of it.

1114 Robert FultonFebruary 24, 1815: Robert Fulton dies. 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.”

#TDIWH–February 23, 1893: Interstate Quarantine Act Becomes Law

0223 Interstate Quarantine RegulationsFebruary 23, 1893: Interstate Quarantine Act becomes law. “In 1893 Congress passed the Interstate Quarantine Act to reduce the spread of communicable diseases through interstate commerce. The act gave the Department of the Treasury broad powers to establish regulations preventing the spread of disease from one state to another in the following clause (Cumming 1932; Kraut 1994):

‘The Secretary of the Treasury shall, if in his judgment it is necessary and proper, make such additional rules and regulations as are necessary to prevent the introduction of such diseases (communicable) into the United States from foreign countries, or into one State or Territory or the District of Columbia from another State or Territory or the District of Columbia ….’

This clause was not immediately perceived as requiring any regulations relating to drinking water. In fact, methods of bacteriological analysis and water treatment were not sufficiently developed at this time for the establishment of quantitative standards.”

Reference: Fischbeck, Paul S. and R. Scott Farrow eds. Improving Regulation: Cases in Environment, Health and Safety. Washington, DC:Resources for the Future. 2001, p. 52.

Commentary: However, in 1912 the common cup was banned on interstate carriers using this law as the basis for regulation by the Treasury Department. In 1914, the first microbiological drinking water regulations were adopted under the Interstate Quarantine Act that governed the quality of water served aboard interstate carriers (trains, riverboats and Great Lakes steamers).

#TDIWH–February 22, 1913: Wallace and Tiernan and Over 100 years of Chlorination; 1989: Abel Wolman Dies

0222 Old Number OneFebruary 22, 1913: Over 100 Years of chlorination by Wallace & Tiernan. The company’s first gas-feed chlorinator, an experimental apparatus, was installed on a tributary of the Rockaway River at Dover, New Jersey, on February 22, 1913. Wallace & Tiernan was the dominant producer of chlorination equipment in the first decades of the twentieth century. Wallace & Tiernan were first founded in New York City, but shortly thereafter, they moved their administrative and manufacturing operations to Belleville, New Jersey. There were many connections between the early days of Wallace & Tiernan and the Jersey City water supply. William Griffin, superintendent of the Jersey City water department, hired Charles F. Wallace and Martin F. Tiernan to disinfect the polluted stream near Dover that was contaminating the Rockaway River as it flowed into Boonton Reservoir. Two of the expert witness in the Jersey City trials, Charles E. North and Earle B. Phelps, hired the two men in the very beginning of their careers to help install disinfection systems in cities as part of North and Phelps’s consulting practice. Tiernan actually ran the chloride of lime feed system at Boonton Reservoir in the early fall of 1912 when the chemist was on vacation.

0222 Abel WolmanFebruary 22, 1989: Abel Wolman dies. “Abel Wolman (June 10, 1892 – February 22, 1989) was an American inventor, scientist, professor and pioneer of modern sanitary engineering.

Wolman was born, grew up, was educated, lived and died in Baltimore, Maryland. He graduated from the Baltimore City College in 1909, got a B.A. from the Johns Hopkins University in 1913 and then a B.S. in engineering from Hopkins in 1915. From 1914 to 1939, Wolman worked for the Maryland State Department of Health, serving as Chief Engineer from 1922 to 1939. It was during his early years there that he made his most important contribution. Working in cooperation with chemist Linn Enslow, he standardized the methods used to chlorinate Baltimore’s drinking-water supply. His efforts there helped develop the plan for Baltimore’s water supply so thoroughly and effectively that it remains well-provided for growth through the 21st century. His work also benefited water systems in New York, Detroit and Columbus, Ohio. A collection of his writings has been published: Water, Health and Society, Selected Papers. Wolman served as the Chairman of the Advisory Council for planning Israel’s National Water Carrier project (1950-1956).

Wolman taught for many years on the faculty of Johns Hopkins University, where he established the Department of Sanitary Engineering in 1937. He served as the department’s chairman until his official retirement in 1962….

Wolman became Editor of the American Water Works Association’s Journal AWWA in 1919 and was responsible for making it into a monthly publication in 1924. The Association presents the Abel Wolman Award of Excellence each year to recognize those whose careers in the water works industry exemplify vision, creativity, and excellent professional performance characteristic of Wolman’s long and productive career.”

Commentary: It is fitting that the anniversary of the first use of a Wallace & Tiernan chlorinator falls on the anniversary of Abel Wolman’s death. In the early 1920s, he and Linn Enslow modernized the system for determining the needed chlorine dose to provide safe drinking water. Prior to their work, chlorine doses were a matter of much guesswork.

#TDIWH—February 21, 1895: Aeration to Purify Sewage and a Letter from George Warren Fuller

Spray Aeration

Spray Aeration

February 21, 1895: Letter to Engineering News. Aeration as a Means of Purifying Sewage and Water. by J.H. Curtis. “The subject of sewage disposal and the purification of alluvial river water has been long considered and well digested by chemists, but the engineering end of the question has seemed to lag. About a year ago the subject was experimented on at St. Louis, and the result of these experiments may be given as follows:

Aeration was employed in which the liquid to be treated is absolutely disintegrated or reduced to spray. At the same instant of time and in juxtaposition with the liquid spray must be an atom of disintegrated air. What is the result? Organic matter accompanying the liquid is at once seized by the different constituents of the air, and there is produced pure water and harmless inorganic compounds. How performed? By a screen floor, say, with pepper-box perforations, over which is a layer of coarse river sand, somewhere below another layer of sand, leaving an air chamber between the two. Then, to duplicate nature, cause a rain storm of the liquid to be purified by forcing air into the chamber of a little less pressure than what is sufficient to sustain the weight of the liquid in the tank.

These drops falling on the fine sand, which must be kept unsubmerged, are then and there purified. [Mr. Curtis then goes on to quote the results from some experiments conducted at the Lawrence Experiment Station in Massachusetts. The experiments were run by none other than George Warren Fuller. The article continues…]

At the request of Mr. Curtis we have submitted proofs of his communication to Mr. Geo. W. Fuller, Biologist-in-Charge of the Lawrence Experiment Station of the Massachusetts State Board of Health. Mr. Fuller has made some comments on the subject, which are given immediately below. -Ed.)

Sir: The reference by Mr. Curtis to the Report of the Massachusetts State Board of Health on the purification of sewage by intermittent filtration, where artificial aeration is used for the removal of air in the filters, shows such a complete misapprehension of the process of purification by bacterial action, as well as misconception of the results of our work, that it is difficult to comment on the statements In his letter. He has entirely missed the idea of purification in the series of intermittent sewage filters Nos. 12A, 15B and 16B, which have been described in our Reports for 1892 and 1893.

It seems to me unnecessary to comment on his scheme until he has some facts to give with regard to this bacterial and organic purification of water and sewage by his system.

Truly yours,

George W. Fuller.

Commentary: There are very few letters written by George Warren Fuller that have survived to the present day. It is clear from this letter that he did not suffer fools gladly even at the tender age of 27 when the letter was written.

#TDIWH–February 20, 1862: Willie Lincoln Dies of Typhoid

250px-WILLIEFebruary 20, 1862: President Abraham Lincoln and Mary Todd Lincoln were grief stricken when their eleven-year-old son, Willie, died from typhoid fever, which may have been due to polluted drinking water delivered to the White House. His full name was William Wallace Lincoln but his parents called him Willie.

“Willie and his younger brother Tad were considered “notorious hellions” during the period they lived in Springfield. They’re recorded by Abraham’s law partner William Herndon for turning their law office upside down; pulling the books off the shelves while their father appeared oblivious to their behavior.

Upon their father’s election as President both Willie and Tad moved into the White House and it became their new playground. At the request of Mrs. Lincoln, Julia Taft brought her younger brothers, 12-year-old “Bud” and 8-year-old “Holly” to the White House and they became playmates of Willie and Tad.

Willie and Tad both became ill in early 1862, and although Tad recovered, Willie’s condition fluctuated from day to day. The most likely cause of the illness was typhoid fever, which was usually contracted by consumption of fecally contaminated food/water. The White House drew its water from the Potomac River, along which thousands of soldiers and horses were camped. Gradually Willie weakened, and both parents spent much time at his bedside. Finally, on Thursday, February 20, 1862, at 5:00 p.m., Willie died. Abraham said, ‘My poor boy. He was too good for this earth. God has called him home. I know that he is much better off in heaven, but then we loved him so. It is hard, hard to have him die!’”

Willie was only 11 years old when he died.

Commentary: Typhoid fever caused by contaminated water killed by the hundreds of thousands every year. The suffering of the parents of children was great and avoidable. It would take Louis Pasteur, the germ theory of disease, Dr. John Snow, public health professionals and the sanitary engineers of the late 19th and early 20th centuries to eventually break the death spiral of sewage contaminated drinking water.

#TDIWH—February 19, 1914: Large Steel Water Tank in Youngstown, OH

0219 Steel TankFebruary 19, 1914: Engineering News article. “A steel tank 100 ft. diameter and 50 ft. high, with a capacity of 2,938,000 gal., is being built at Youngstown, Ohio, in connection with the water-supply service. The design is shown in Fig. 1. There are ten rings of plate, with double-strap butt joints for the vertical seams. These have ten rows of rivets (staggered) in the first two rings, eight in the third, six up to the eighth ring, four in the ninth and two in the tenth or top ring. There is a 20-in. inlet pipe with lead- and oakum-calked joint in the bottom plate, and a 24-in. overflow pipe of 3/8-in. riveted plate….

The tank is built without a roof, but has around the top a steel balcony with hand-rail. This balcony not only serves as a walk but also acts as a horizontal girder to stiffen the top of the tank.

The riveting is done with a large compression yoke riveter, except that the riveting of the bottom and the balcony is done with air hammers. The yoke riveter is suspended from a stiff-leg derrick, as shown in Fig. 3. The mast of this derrick is pivoted in the center of the tank and each stiff-leg is mounted on a small truck riding on a circular track, so that the boom and derrick frame can revolve through a complete circle. The power plant, air compressor and hoisting engine are located just outside the tank. The estimated weight of the tank complete is approximately 500 tons, and there are about 70,000 field rivets.

Reference: “A Large Steel Water Tank.” 1914. Engineering News 71:8(February 19, 1914):412-3.

Commentary: Note the lead and oakum-caulked joint. Lead would still be used in water works facility construction for many decades after 1914. Also, note that the reservoir did not have a roof. Uncovered finished water reservoirs finally suffered their death blow with the USEPA regulation—Long Term 2 Enhanced Surface Water Treatment Rule. This story interested me because of the yoke riveter (on right center of Fig 3 with man standing on top) and derrick. This technology is long gone (I think), but it is interesting to see how they built reservoirs 99 years ago.
