Water’s Flip Side
'For years,' wrote Bruce Zaretsky to open his On the Level column in the January 2011 edition, WaterShapes 'has celebrated the beauty, majesty and positive potential of water in the landscape.  We've seen it flowing down waterfalls, over vanishing edges, across slopes and through the air.  We've seen what happens to colors immersed in it, how it creates shimmering light patterns, how it works its way over stone and, perhaps most important, the

Seeking Perfection
Through the past two years, a handful of voices in this magazine and elsewhere have called for building pools without drains as a means of virtually eliminating suction-entrapment incidents.  The response to this suggestion has been strong, both for and against. In sifting through some of these discussions – including a key interview with Dr. William N. Rowley that appeared online last fall on the WaterShapes Web site – one item caught my eye:  It came from a watershaper who clearly didn’t have
When Pools Crack
Even though many swimming pools look similar in lots of fundamental ways, every one of them is actually quite unique. From soil and groundwater conditions or the specifics of their structural designs to the ways in which they have been installed, water-containing vessels of all shapes, types and sizes are, in fact, subject to a wide array of site- and workmanship-specific variables that can influence the way their concrete shells will perform through the years. When a watershape cracks, any number of things might have gone wrong.  To the owner of a watershape, of course, such cracking is obviously a source of concern.  The fix is often expensive, and it's not at all unusual for contractors to defend their work as a means of avoiding the necessity of paying to remedy the situation. This can leave the owner in a very difficult position in which experts must be called in to determine the true cause of the problem - and then he or she might be left alone to pressure the contractor who installed the vessel to take responsibility and
Reasonable Choices
It's one of the most horrific things that can happen to anyone who enters a pool or a spa:  One moment you're having fun or relaxing, and in a terrible instant you're caught in a devastatingly painful and potentially fatal situation. Most people who become entrapped by pool, spa or wading-pool plumbing do survive, but all too often they suffer life-altering injuries.  As with any aquatic safety issue, we all agree these incidents should be prevented, and a great many talented people from government, trade associations, research institutions, equipment manufacturers and consumer-safety groups have invested a tremendous amount of time in examining suction entrapment.  For all of that effort, however, seeing our way to
Sound Solutions
Developing a simple, reliable swimming pool alarm system offers a remarkable range of technical challenges, observes Robert Jechart of RJE Technologies - even when your point of departure is years of experience with ultra-sophisticated military and commercial sonar technology.  Here, he discusses a four-year process in which his company has addressed its goal of making watershapes safe for families with small children.
