EXAMPLE OF WELL DESIGNED SMALL CITY WATER SUPPLY SYSTEM
Improvements, Much Needed, Endorsed by Vote of Citizens and Successfully Carried Out—Excellent Water Supply Through Wells
THE water system of Ellsworth, Kan., according to Mr. Sulentic, who is consulting engineer in charge of the city’s water works improvement, was first installed 37 years ago. This original supply, ample at the time, eventually was outgrown by the population and early in 1921 tests were made for an entirely new system. In May, 1922, renewed efforts were inaugurated. The further procedure in installing the new water works of Ellsworth is thus described by Mr. Sulentic to whom we are indebted for the illustrations herewith.
A well was dug in the site of block 3, Minnick’s addition, and actual quality and quantity tests started in June, 1922. Continuous pumping developed the fact that this well would deliver one hundred gallons per minute. The water was the kind that had been sought. On recommendation of the city engineer, the council had four more wells drilled near the first one. Each of these wells is thirteen inches in diameter and a little more than twenty Icet deep, with about six feet of water bearing sand and gravel in the bottom.
The old well north of the Frisco depot and west of the track was also tested. Both quantity and quality supply were satisfactory, so it was decided to reconstruct it and install pumps.
Having found the supply desired, it was then decided to further improve the system by connecting all “dead ends” and re-newing all old and deteriorated mains. Extensions were also made to afford fire protection to parts of the city that had been without it.
It was also decided that economy demanded a new steel tank to replace the old wooden tank, found to be rotten in places and liable to collapse in a heavy wind. The height of the old tank, too, was not sufficient to give needed pressure in all parts of town.
The question of making all these improvements was laid before the people at a special election. They gave their approval, and the work was at once pushed rapidly along. The battery of five wells was connected with suction line from three to six inches in diameter, and this line to a vertical turbine pump of nine stage construction, latest type and high efficiency. This pump is directly connected with a 30-horse power vertical induction motor, rotating 1200 revolutions per minute, and delivering 210 gallons of water per minute. Pump, motor and meters are located in neatly and substantially built brick buildings. This battery of wells is known as No. 2 pumping unit, and at the present time it is only necessary to operate this unit four hours a day to furnish all the water needed by the city.
The large well north of the Frisco station is pumping station No. 1. This old well was perfectly cleaned out, sanitary seal of concrete was put in about five feet above the water line, balance of well was plastered, and then concrete top put over it. No. 1 pumping station is equipped same as No. 2 with exception that No. 1 motor is 25 horse-power.
All improvements and changes were made in accordance with instructions from the state board of health, and were made under the supervision of the writer.
A new river crossing line was put in, as shown in the illustration, because it was found that the old steel pipe was corroded and in bad shape.
The wells northwest of town were drilled by W. D. Lough. The brick and concrete work was done by Hayes Storey.
the wiring and electrical apparatus was supplied by the Weber Electric Power Company. Tower and tank were built and put in place by the Chicago Bridge and Iron Works Co.
The city now has a water supply satisfactory in every way. Soft water and plenty of it, and a pressure in the down town districts of 78 pounds.
Fostoria, Ohio, May Electrify Water Works—The proposition to electrify the water works plant of Fostoria, Ohio, is under consideration.
Water Supply in Sight for Weldon—After several unsuccessful attempts in securing an adequate water supply for Weldon, Ill., a contractor has secured what is thought to be a strong vein, at depth of 170 feet.
Pumpage Indicates Waste of Water—The city officials of Bellefontaine, Ohio, announced on Friday, June 22, that over 1,600,000 gallons of water were pumped at the water works on Thursday. This indicates that water is being wasted in various ways and consumers’ have been requested to be less wasteful and use only that amount which is necessary.
