PLATE No. 151. SUGGESTED DESIGN FOR CONCRETE WADING POOL 



(Used through the courtesy of the Portland Cement Association.) 



A suggested design for a wading pool is shown on this page. As planned, the maximum depth of water is 

 uniformly 12 inches. This maximum can be decreased if desirable by placing the outlet lower, thus lowering the 

 water level correspondingly. This pool has an over-all diameter of 50 feet. A sloping pavement permits easy 

 entrance to the water. The construction throughout should be of 1:2:3 concrete, mixed and otherwise handled 

 as recommended in the construction of swimming pools. On account of the sloping sides of the pool formed by the 

 slabs that constitute its rim, there is little or no possibility of the pool being injured by allowing the water to freeze. 

 For this reason the pool will form a safe skating pond during the winter months. An approximate estimate of the 

 materials necessary to construct a wading pool of this plan and dimensions is as follows: Portland cement, 91 

 barrels; sand, 27 cubic yards; pebbles or broken stone, 41 cubic yards; reinforcement, 735 pounds of wire fabric 

 (0.35 pound per square foot); concrete tile, 190 feet of six-inch.
