A Tight Set

   While the pool itself laid out nicely in the available space, the equipment pad was another matter. confined to a six-by-six foot space, it made us unusually conscious of layout and equipment selection.
   In all, there are five WhisperFlo pumps (Pentair Pool Products, Sanford, N.C.) and dual diatomaceous-earth filters (Hayward Pool Products, Elizabeth, N.J.) - one for the edge effect, the other for the main circulation/heating system. All of the pumps are plumbed with dual suction lines to prevent any chance of suction entrapment.
   The main circulation system is designed for a six- hour turnover. Everything runs on two-inch (or larger) plumbing sizes to maximize hydraulic efficiency. We actually downsized the perimeter-overflow pump because the leveling is so tight that the entire effect runs on less than 100 gallons per minute.
  the square spa measures seven by seven feet and also features a perimeter overflow on two sides - one flowing to the trough, the other into the pool. It has 17 jets in all, placed in accordance with the homeowner's preferences. We avoided specialty therapy jets to avoid disrupting the appearance of the interior finish.
   With contemporary designs such as this one, the key to success is paying attention to the elegant simplicity of the details. The project (and the one described in the sidebar on page 57) demonstrates how basic, rectilinear pools with carefully selected design elements have a power and beauty you don't often see, even in more elaborate projects.
   When a designer with Singer's deft touch and flair for visual drama is on the case, the results are truly memorable - and a builder's delight.
