Topeka’s New Water Supply.
The engineers having charge of the new addition to the water-works system in Topeka, Kan., promise to flow water through the pipes by the middle of next month. The new building is built of Cottonwood Falls stone, finished in the rough. A Knowles pump having a capacity of 3,000,000 gallons in twenty-four hours is up and connected with the mains. A 4,000,000 gallon pump will be taken from the present station and placed in the new building.
The drive wells, from which the water is derived, are a new source of supply for Topeka, Heretofore the water has been obtained from large wells on an island in the river, supplied by percolations through the sand at the new station. There are twenty-three of these wells, and the pumps recently erected will connect with them by means of a 24-inch suction pipe. This pipe, however, is only twenty-four inches where it joins the pump, and it thence extends to the sand bur by means of a number of graduating pipes, one for each well. The area covered by the wells is some 250 square feet. The tubes are driven thirty feet to solid rock, and are perforated for a distance of twelve feet only from the bottom. The connections with the main are made just below water level, and the water sucked through the pipes will come from a point eighteen feet below the water line. The pumping station is three miles west of the city, and considerably above factories, etc. The water is of exceptional quality.
