Improvement in the Source of Water Supply at Winfield, Kansas.
The supply for the water-works system at Winfield, Kansas, was formerly taken from a well on the west side of the Walnut river. This well, however, being supplied directly from the river was subject to all the contamination which the parent stream received from Timber Creek which empties into it but one hundred and fifty yards above.
When the water-works plant changed hands, rather more than a year ago, the first move was in the direction of securing a supply that would be above reproach. Several months were spent in testing for a ground water supply. This having been determined to be out of the question, the second move was to secure it from the river, but above all possible source of sewage contamination, and where the water is of most excellent quality, excepting perhaps the large percentage of carbonates of lime and magnesia, as shown by the following analysis :
How to accomplish this end was the question. To remove the pumping station would be a matter of great expense, so it was determined to reverse the case of Mahomet and fetch the “mountain.” In this case, however, it was a river. Accordingly a circular wood conduit, made from Southern hard pine, sixteen inches internal diameter was built in the manner shown in the illustration.
This being connected directly with the suction pipe crossing the river was carried up to a point 1500 feet above the pumping station, where it terminates in a crib 14′ X 14′ X 8’, with centre well 4′ X 6′, the rest of crib being filled with clean, broken stone, the size of ordinary top course macadam. The crib is well riprapped on the outside, and provided with an apron to throw off floating logs and debris. The supply pipe has direct connection, through a valve, with the reservoir, so that at any time it can be cleansed by having back water run through it at a pressure of seventy pounds to the square inch.
This improvement places the source of supply beyond all possibility of sewage or drainage contamination from the city, and gives the best water supply obtainable.
The present management has been unceasing in its efforts as well as unsparing in expenditure not only to give Winfield, one of the most beautiful little cities of southern Kansas, an inapproachable water supply, but a perfect system in every particular.
Our illustrations show the method adopted in the construction of the wooden conduit, and the intake crib completed with the conduit ready to be sunk.
The improvements, when finished, were inspected by the members of the city council of Winfield and the editors of the local newspapers, and the enterprise of the company as well as the ingenuity and skill of Superintendent J. H. Decker, under whose supervision the work was carried out, were heartily commended.
