MEETING OF 4-STATE SECTION OF AMERICAN WATER WORKS ASSOCIATION

MEETING OF 4-STATE SECTION OF AMERICAN WATER WORKS ASSOCIATION

The last meeting of the 4-State Section of the American Water Works Association was held at the Bellevue-Stratford Hotel, Philadelphia, Pa., on last Wednesday. Luncheon was first served, after which Chairman C. E. Davis called the meeting to order. Chairman Davis expressed his apprecaition of the perfect co-operation he received from the various members of the executive committee, and particularly gave credit to Mr. Charles R. Wood, the efficient secretary and treasurer of the local organization. The chairman spoke shortly on the duty of water works men in cooperating with the government to protect industries from water shortage due to damage to water plants. John C. Trautwine, Jr., represented the Mayor in welcoming the delegates to the city. He introduced Mayor Ellis of Camden, N. J., who delivered a very interesting talk on city co-operation with the Federal Government during the present crisis. Mayor Ellis spoke of the conditions which administrative heads of cities are now facing and the necessity of ruling with a strong hand. “The importance of the water works plant,” he said, “cannot be overestimated. Let it go out of business for 48 hours and see what a tremendous uprising there will be. Let a little dirty water get into the mains and see how quickly the inquiries come in. The failure of the water works plant will stop everything. The industries can protect themselves by placing barbed wire, etc., around, but the water plant is still more important, for its failure means a shutdown. The present is not a time to question duty, and it is the duty of every water works man to urge co-operation in protecting the water plant. The city of Camden made an original investment of $500,000 in its water works plant and less than this amount later on for repairs and replacings. At the present time we could sell it for $5,000,000. At the present hour typhoid fever is not known at Camden, for the artesian system supplies an abundant quantity of pure water, and the source seems to be inexhaustible. It is a credit to the association that it took members of it to design the Camden work.” Mayor Ellis ended up his talk by inviting the section to hold its next meeting at Camden.

The nominating committee presented the names of the following, all present officers of the association, for re-election:

President, C. E. Davis, chief engineer, Bureau of Water, Philadelphia, Pa.; vice-president, E. M. Hoops, chief engineer of water department, Wilmington, Del.; vice-president,

L.Van Gilder, superintendent of water works, Atlantic City, N. J.; secretary-treasurer, Chas.

R.Wood. Philadelphia, Pa.; executive committee, J. W. I.adoux, American Pipe and Construction Company. These names were presented for vote and the election was unanimous.

The paper of the afternoon, by J. N. Chester, consulting engineer of Pittsburgh, Pa., was entitled “Service Charge, How Constituted.” The speaker described the various systems of charging for the service connection and especially compared the system recommended by the committee of the New England Water Works Association to the system which he himself developed.

The paper was discussed by Mr. Ladoux, E. M. Nichols, E. M. Hoops, John C. Trautwein, Jr., and Mr. Gibson.

MEETING OF “4-STATE SECTION” OF AMERICAN WATER WORKS ASSOCIATION

The first meeting of the season of the “4 State Section” of the American Water Works Association was held at Wilmington, Del., last Wednesday. Those delegates who arrived at Wilmington in the morning were taken by automobiles to see the reservoir and the filtration plant now under course of construction, hollowing the trip over the new work, luncheon was served at the Hotel du font, alter which the business session was held. Chairman Hilies, of the Wilmington Water Board, welcomed the guests to the city, after which Thos. W. Miller, representing the city, made a few remarks, calling attention to the work that Wilmington has done towards bettering its water supply. He pointed out that it was one of the first cities to install a filration plan for the purification of the domestic water supply, and also one of the first to construct intercepting sewers to aid in keeping the water supply pure. C. E. Davis, Chief Engineer of the Philadelphia Water Bureau, and chairman of the Section, spoke briefly before introducing the main speaker of the session, George W. Fuller, and called attention to the fact that while the “4 State Section” was the youngest of all sections of the American Water Works Association, its membership is. rapidly gaining on other divisions, and it promises to become a leader.

Address by George W. Fuller.

George W. Fuller started his talk with a brief review of the history of the Wilmington water works. Many important features in water works improvement, he said, have originated in Wilmington. With regard to the Wilmington water works, there are tnree distinct phases in its development. The first dates hack to 1870, and from thence to 1903. During that period the city tried out the “Sellers” fitration plant, it was during 1892, when the cholera epidemic broke out in Hamburg, and Wilmington feared for the safety ol her citizens, that the filter was built. A similar plant had been ereettd at Lawrence and placed in operation. The “Sellers” filter m the city consisted of five units. Each was 15 feet by approximately 130 feet. Between the third and fourth units an intercepting sewer was built. This plant aroused a great deal of interest, for it showed tne results of filtering the polluted water of Brandywine creek. Water was taken from a diverting dam on the creek and was led through a headrace to the old Wheel House, where the pumps were located. This filter and piping arrangement were employed until 1903. It was then time to reorganize the water works.

Under the second phase of the city water works, Mr. Fuller told of what had been done in recent years for its improvement, adding: “The water department has placed a meter on every service in the city—no consumers being missed. The department is aide to account for 76 per cent, of the water that is emptied into the distribution system. In the majority of metered cities only 55 to 65 per cent, of the water pumped can be accounted for. This period also saw the ipt reduction of the first commercial application of devices for administering liquid chlorine to purify water.

“Coming up to the third phase, in 1916, I will state briefly the developments, for they are those which you saw to-day. fit this city there is a great demand for water at the present time, due, no doubt, to the large industrial demand. The present slow sand filters are to be repaired and improved this year. They have heretofore been very efficient in removing the color and suspended matter in the water. It was, however, my recommendation that mechanical filters be installed. Greater flexibility is needed in the filter plant. The mechanical filters arc being built near the present pumping plant, and the water will leave a large share of its turbidity there. From the filters water will pass through a 48-inch cast iron water pipe to the suction well in the old Wheel House. It may be of interest to state that the old Wheel House was a house which contained water wheels used in running the old pumping engines. The new pumps to ue installed will be of the centrituga type. Tne new tcodney street reservoir now being built will replace tne old one. It will have a capacity of 7,500,000 gallons, will be of concrete construction, and covered, it will be so arranged that during tne summer montns a roller skating will be provided thereon for children, while in the winter it may be Hooded and used as an ice skating rink. The two filters will work in steps. Generally speaking, the two will be available, but at the start, the new one will be put to work alone while the old one is being repaired. When they are both in shape, the one which is best suited for the conditions at any particular time will be used. I should make one other comment, relative to the different pressure zones. In Wilmington there are three zones: The low service, which serves the commercial section; a middle zone, and the extreme high service zone at the western end of the city, which is supplied from a tower tank.

An effort was made some time ago by the water commissioners to see if the water, supply could not be drawn from Brandywine creek above the city. Difficulties were met in securing rights to property involved, so the scheme fell through. During recent years I have looked over the operating end of many water works plants, and I must admit that this is one of the best managed plants I have ever met with. It is operated under very efficient conditions indeed. I compliment the management for their every efficient showing.

Talk by John Groves.

John Groves said : For many years I was registrar of the Wilmington Water Dept, and so have taken a great interest in the progress of the Wilmington water works. I feel highly honored in being invited to speak here. In the first place I might mention that the water supply of this city is of the very best. It is improving continually. It was in 1886 that I first became connected with the water works. At that time the Sellers filter was in operation. It was an upward process filter. In 1883, William T. Porter made the statement that the City Water Department could be self-sustaining. Many opposed his views. However, at the beginning, the Commissioners who were chosen to manage the water department had to go out and borrow sufficient money to put the plant on an operating basis. In 1184 they were permitted to take over the control of the water department. Since that time the management of the water board has proven very efficient. Following Mr. Grove’s brief talk, Chairman Davis read a communication from John C. Trautwine, Jr., of Philadelphia. A discussion was then invited on Mr. Fuller’s paper, but no one responded.

Remarks by Edgar M. Hoopes, Jr.

By request of the chairman, Mr. Edgar M. Hoopes, Jr., chief engineer of the Wilmington Water Department, spoke in part as follows: “I cannot add very much to Mr. Fuller’s remarks, in Wilmington we have had almost all of the filtered troubles conceivable, terminating with the recent air-binding troubles. The water works were purchased from the water company in 1820. It is one of the oldest in the country. When the filter was first installed iron was used as a coagulant. Scrap iron was passed through the water on a moving belt, and it was figured that sufficient iron would be liberated in the water to coagulate the small particles in suspension. This city has had many typhoid epidemics but it was not until 1902 that the question of filtration was started. The slow sand filters which w»ere installed have done very good work. At times they have been called upon to remove turbidity of thirty-six parts per million. The point which was of most interest occurred one vear after the filter was installed when an exceptionally cold winter set in. Twelve inches of ice formed over the filter beds. It was necessary to remove the ice by blasting and other means. Shortly alter the opening of the filter there developed the peculiar phenomena of air-binding. When this takes place all beds go out ot service at once without warning, and as the dear water basin holds only 6,000,000 gallons while our daily consumpuon is12,000,000. There was only one-half day’s supply to fall back upon so we had to get tne filtersin operation within this period. We realized that the air-binding here was due to structural defects. Air-binding usually occurs at low temperatures. When this situation developed we realized: we had a very serious problem to solve. We must either build a duplicate set of the samekind of filters or depart completely from this practice. It is finally decided to employ mechanical filters.

In increasing our pumping capacity we decided to use centrifugal pumps instead of h gh duty reciprocating pumps. Our action in this matter was the result of three imposed conditions; namely, time to manufacturer, space available, and cost-

Owing to war conditions the manufacturers of heavy pumping machinery were unable to guarantee deliverey in less than nine months. On the other hand the space available in our pumping situation was not sufficient for large machinery after leaving space open for a future installation of a duplicate of one of the high duty reciprocating now in service.”

Following Mr. Hoopes’ talk a short discussion as to the classification of laundries when arranging water rates was held. The concensus of opinion was that they should be classed entirely on their consumption: that is, if they consume a large amount of water they should enjoy the industrial rate, while if the amount of water used was very small, charge therefore should he made at dwelling house rates.
