crosswall and then two inches of the top of the center crosswall knocked out, giving you a two-inch channel in the block. The full block is scored as shown on the right of the illustration, the crosswall knocked out is shown in the center view. On the left is shown a two-inch thick concrete block which is used under special cases. Figure CZ shows this block being set up in a wall, fully enforced with steel vertically and horizontally in the little channel which you see in this arrangement. This particular picture also shows the end cross wall in the Ovoid pool which gives you the specific length of pool required and squares up the ends for acquatic meets. Figure C3 shows some precast concrete pieces which go into the wall. Toward the back are the Depth Sign blocks which are put on the deck around the pool and on the side of which is printed the depth of the pool. In the foreground and to the left there is a block which takes the place of one of the concrete blocks, but on which there

is an extension which forms a step which you will see in a later picture. This same block is shown upside down to the right of the picture and shows the scoring at the edge of the wall and the hole through the block for the steel to pass through it. Figure C4, shows the wall entirely built up. On the face of the wall is laid a steel mesh, which is held against the main wall with wires which have been cast in the wall when it was laid up. Then onto the wall is placed a one inch surface of concrete for a facing. And finally figure C5 shows the completed wall with the step and handhold, and also shows an underwater light where such a. light might be used.

Now we might say that the particular ladder in this illustration, made up in this fashion, will cost about $10. To buy a ladder to put into the pool would cost, today, about $38. Now that is just one example of how proper professional service will pay for itself many times over in such a structure. Incidentally,

FIGURE C-4 shows the wall entirely built up. A steel mesh and one inch of concrete is applied.

this block construction will also save about 70 cents per square foot of wall by eliminating the form work required normally for a poured wall. There are a lot of other details that cant be shown in such an article as this, but the above two items on the wall and the steps indicate just how proper professional service is necessary to anyone who decides to build a swimming pool.

Pool Operation

With the pool built, it must be operated. Cash outlays are required to pay for electric current-power and light for the pool, sterilizing agentseto keep the pool sterile, laundry supplies*to clean up and sweep around the pool, vacuum cleaner#to clean the pool bottom, and the personnel to operate the pool and the bathhouse. In the table prepared especially for this article the probable operating costs for the several sizes have been set up. These costs are not as high as a great many people think, but are predicated on one-third of a century of pool service by the writer and will cover costs if the pool is operated at maximum efliciency.


In the matter of maintenance, there is much or little depending upon how the structure is built. If the structure is properly built, properly engineered, the pool should have very little service requirements except repainting every two or three years. As far as the bathhouse is concerned, the same thing applies. If it is a cheap little wooden structure, itill take a lot of paint and maintenance. If it is of a more permanent structure of brick and stone and concrete, then the maintenance again amounts to a. very little with the exception of repainting every two or three years. This item is also covered in the accompanying table.

We might add here that the matter of operation and maintenance are two different items. One is the cost of running the pool and servicing the bathers, and the other is keeping the capital investment intact over the years, due to the depreciation that enters into every structure.

The pool and bathhouse, depending upon how it is built and assuming that it is properly built, should have a depreciation figure of about two and onehalf per cent per year. The equipment, such as filters, lockers and so forth, should carry a depreciation item of about five per cent a year. In other words, figure the pool with a 40-year life and the equipment with a 20-year life.

State Board of Health

Now a word about the State Board of Health. The plans and specifications for a swimming pool must be approved by the State Board of Health before any swimming pool is built. To start a pool and not get such approval would merely result in being held up until such time as such plans and specifications have been prepared. These plans must be submitted to the State Board of Health before construction starts, and the
