Allen Director of Physical Education Varsity Basket Ball Coach University of Kansas Lawrence, Kansas Dear Sir: On May 13th the writter made a final inspection of the swimming pool filter and recirculating system which is located in the gymnasium building, Incidentally, we discovered that the pool is of obselete design and, of course, it is very difficult to obtain the desired results, inasmuch as the pool has no scum gutters and, furthermore, a depth of water of approximately 8t is maintained over the entire area, Modern pools, as you no doubt know, have a shallow end of approximately 3! to ' of water, and slope down to a depth of be- tween 8' and 9! of water. This is to enable beginners to use the shallow end and, of course, the experienced swimmers the deep end. There is nothing that can be done to improve the pool as the cost would be prohibitive. However, the final results that are now being obtained under the present set-up should be appreciated and, no doubt, such — results are due to careful operation, Now, in regard to rehabilitating the present filter and recirculating system, we recommend the following: 1. A jie ‘Lestebinitne pump and motor should be install- ed as the present unit has too small a capacity. In other words, according to our figures, with your pre- sent pump the contents of the pool are turned over once every 18-1/2 hours and by furnishing a larger pump and motor the contents of the pool would be turned over every 12-1/2 hours. However, according to the best practice, the pool should be turned over once every 8 hours, but this cannot be done, owing to the size of your present filter itself. It is not advisable to furnish a larger filter at this time as it would be impractical to do so, because of the space available and also the question of re- moving the present filter and installing a new one,
