American Water Works Section Holds Its Fourth Annual Convention-Many Excellent Exhibits Are Shown-Nearly Every California City Represented

WITH very nearly every city in the state represented and with a large attendance, the California Section of the American Water Works Association held its fourth annual convention at the American Legion Hall, Fresno, Cal., on October 25 to 27. A feature of the convention was an excellent line of exhibits by manufacturers from all parts of the country.

Opening Session, October 25

The convention was officially opened on October 25 at 2 p. m. by President L. M. Anderson, comptroller of the department of public service of Los Angeles. The delegates were welcomed by A. E. Wishon. general manager, of San Joaquin Light ft Power Corporation and the Fresno CityWater Corporation. In his address, Mr. Wishon traced the history of water supply through the ages and compared the present session to a conference held in Rome almost two thousand years ago when the question of economic and efficient distribution of pure water for domestic use in Rome was the great problem. Mr. Wishon said: “You gentlemen

in session here today are meeting for the same purpose. Although civilization has progressed far, and the methods of the distribution of water for domestic use have improved much, your purpose is the same—to bring about greater efficiency and economy in the distribution of pure water for domestic use.” He welcomed the members and hoped that they would accomplish much during the session. He said that the latchstring was always hanging out for the members now and at all times.

A paper was read by E. K. Barnum, engineer of the Fresno City Water Corporation, which described the system of Fresno and gave a brief historical description of it taken from a report made by the J. G. White Company in 1911. In that year, the population of Fresno was about 30,000 with a distribution system of 68.2 miles of pipe from 3 to 12 inches in size, supplying approximately 4,500 services. Today the population is estimated at 69,000, the figure being based on the entire area served by the water company, or approximately six square miles. There are now being operated 27 pumping plants with a total capacity of 33,400 gallons per minute, or 48.15 million gallons daily. The second paper was by George Read, superintendent of meters and services, bureau of water works and supply, Los Angeles. This paper, the title of which was “Proper Arrangement of Plumbing for Buildings Higher than can be Adequately Served Directly from Distributing System,” was read by Samuel B. Morris, chief engineer, Los Angeles, who is secretary of the section, in the absence of Mr. Read. Mr. Morris also discussed types of pipes for main water construction. This was followed by a general discussion of the members. During this session the ladies of the convention were taken on a motor tour through the city and were guests at a luncheon and musicale at the Sunny Side Country Club. At 6 p. m. there was an informal dinner at the Fresno Hotel, which was followed by the evening session with reading of papers.

Sessions of Second Day, October 26

The two sessions of the second day were given up to the reading of several papers and their discussion. Among these was a paper by Dr. Carl Wilson, bacteriologist, bureau of water works and supply, Los Angeles, on “Reasonable Water Sanitation Requirements.” Dr. Wilson said that two facts which may serve as guide posts when attempting to arrive at a standard, are these: “The public health must be pro-

tected at any cost, and we should never pay more for a thing than it is worth.” Dr. Wilson continued, “Our course, then, is plain. We must prevent water borne disease at all cost, but purification or treatment of water beyond a point which will eliminate typhoid and allied diseases is an unjustifiable expense.”

He quoted various authorities on the origin of diseases which might be laid to impure water, and outlined precautions to he taken by water works for the treatment of water in catchment areas, impounding systems, and distributing systems. Dr. Wilson further said: “1 do not believe in

one standard to fit all kinds of water. I may even go further, saying that the stored supplies of two cities such as San Francisco and Ixs Angeles, might he equally safe, and yet have widely variant normal (harmless) colon content. Individual study, coustant vigilanci and good engineering judgment must determine what is sa» on any surface supply, and no hard and fast bacterial standard, however strict, can ever supercede them in the control of water.”

Louis Stocklmeir, engineer of the Pacific Board of Fire L nderwriters. spoke on the “Etfect ot Distributing Svstem Design Upon Fire Insurance Rates.” He said that thedeficiency points of any given city are taken into consideration when basing insurance rates of certain classes alter building deficiencies and other basic points have been computed. The total number of pointof deficiency affecting the rates is five thousand of which 17 hundred points depend on the supply of the city in question, 1 his is more deficiency points than is controlled by any other of the seven gradingwhich are on water supply, fire department, fire alarm system, police, building laws, hazards and structural conditions.

Other papers read were, “Softening of Public Water SupPlies” by Gale S. Strout. consulting engineer, San Francisco, and Mater Measuring Devices, by R. L. Daugherty, prolessor of mechanical engineering and hydraulics, California Institute of Technology. Pasadena.

Luncheon to the Exhibitors

At noon, the exhibitors at the convention were tendered a luncheon at the Sunny Side Country Club. Alexander Bell, Pacific Coast manager, M’allace & Ticrnan Company, Inc., Newark, N. J., was chairman and the speaker was C. B. Jackson, superintendent of the Fresno City Water Corporation. Among those who exhibited at the convention were the following: M’atcr M’orks Supply Company of San Francisco, James Jones (v Co., Los Angeles; Worthington Pump and Machinery Corp.. New York City; l’ittsburghDes Moines Steel Co.. Pittsburgh, Pa.; Art Concrete Co., Pasadena; DeLaval Steam Turbine Co., Trenton. N. I.; C. E. Sirch, filtration engineer, Los Angeles; Me El wain Co.’, Los Angeles; Hersey Manufacturing Co., South Boston, Mass.; United States Cast Iron Pipe & Foundry Co. Burlington, N. J.; National Meter Co., New York City; H. Mueller Manufacturing Co., Decatur, 111.; M’allace A Ticrnan Co., Inc., Newark, N. J., and others.

In the evening, an address was given at the Fresno Hotel by Charles Gilman Hyde, professor of sanitary engineering, university of CJnliforiiis, on “European Expcrinccs.” It was announced that the convention city for 1924 would be Sacramento.

Automobile Trip on Saturday

On Saturday the entire convention was taken on an automobile trip to Kerchoff Dam and power house of the San Joaquin Light & Power Corporation. Luncheon was provided at the power house by the company. The return to Fresno was at 4 p. m. and in the evening there were fiveminute talks on a great number of important water works subjects.
