If ever there was an example of the power of simplicity, it's been the rise of what we call floating-granite-ball fountains. They've been around since the early 1990s and are now found in a range of commercial and even residential settings. I hadn't ever seen one when I joined HydroDramatics back in 1996, but I do know that soon after I started we began receiving a steady flow on inquiries about them - and it wasn't long before we received our first commission for a floating sphere for a major automobile manufacturer in Detroit. As has been the case every time a prospect has asked about one of these fountains since then, school administrators wanted

As watershapes have become increasingly complex, the need for reliable hydraulic designs that maximize efficiency and reliability is now more pressing than it’s ever been, says hydraulics expert Steve Gutai. With this installment of his ongoing series on hydraulics, he launches a sequence of articles that will explore principles behind the fluid mechanics and hydraulics of custom
It's a fact: A great many of the ponds and lakes in the western United States are simply not part of nature's scheme. Whether used for water retention, landscape beautification, fishing or swimming, these artificial, man-made bodies of water are inclined (and in some cases doomed) to be troubled, usually because of fertilizer- and pesticide-laced runoff from surrounding developed areas. Indeed, some of these problem watershapes are filled with just about the worst water the environment has to offer. As our business has developed, a large portion of what we do has focused on setting things right in these troubled watershapes and
Fifteen years ago, aquatic play attractions were found mainly in commercial waterparks in the form of large, multi-level, themed structures. Some smaller elements were found in the shallow ends of swimming pools, but they were generally limited to a few play apparatuses such as water umbrellas. Much has changed in recent years, and aquatic play systems are now featured in a greater variety of settings including city parks, recreation centers, resorts and a range of other recreational spaces. This trend did not burst forth overnight: For more than ten years, our firm and others have been helping things along by focusing attention on the value of concepts related to zero-depth aquatic play. We at Vortex Aquatic Structures in Montreal, for example, have designed our "Splashpads" to bring the joy and recreational value of aquatic play to almost any space. Among our objectives is bringing a measure of the commercial waterpark experience to places such as neighborhood parks, housing developments, campgrounds and other facilities, thereby allowing everyone within a community to experience
A couple months back, the National Association of Home Builders held its annual convention in Orlando, Fla. - a massive January affair that drew more than 120,000 attendees to view all manner of products falling under the broad umbrella of "home construction." One of the annual centerpieces of NAHB's event is the New American Home program. Each year, select local contractors build a state-of-the-art home in the show's host city to put the absolute cutting edge of residential design and construction on display. During the convention, show organizers sell tickets for tours, and thousands of people tour the home. Once the tours are concluded, the home is sold and becomes a deluxe private residence - and a lot of money from ticket sales flows to charity. I was fortunate enough to be asked to
Backwash valves are the unsung heroes of many a fine hydraulic system. Seldom considered other than when in use, these handy devices simplify filter maintenance, significantly extend filter cycles and even serve to stretch the service lives of a filter’s internal components. Ensuring that level of reliable performance, says hydraulics expert Steve Gutai, is a matter of understanding the role these valves play and selecting the right one for the given application. Backwash valves are simple in concept: They reverse the flow of water through a filter and, in so doing, dislodge dirt and debris that has built up on the surface of and in the filter medium. This procedure has a couple of key benefits in both sand and diatomaceous-earth filters: First, it improves filter performance by breaking up and flushing out the near-solid cakes of dirt and oil particles that build up in the media over time. Second, it prolongs filter cycles and extends the time between major (and messy) cleanings. Third, because they minimize those invasive cleanings, backwashing helps to extend the service lives of a filter’s internal components. For all that, I keep seeing systems in the field in which backwash valves are
As much I enjoy seeing my own projects come to fruition, there's something wonderful in seeing watershapers I know achieve great results in their work. I admire and encourage the effort, especially when the outstanding outcomes are the result of a professional's concentrated efforts to improve his or her own skills. This is one of the reasons I teach: I take great satisfaction in sharing my techniques, sensibilities and the conviction that what I do is special, a true form of art.Sometimes I speak with former
Watershape construction is far more sophisticated now than at any time in history. Swimming pools, for instance, are commonly designed to include spas with complex jet manifolds and a wide variety of controllable effects, while vanishing edges, perimeter-overflow details, multiple water levels and various water-in-transit designs are also increasing in popularity. Fountains and waterfalls and the full range of other waterfeatures also are more elaborate, and what all of them require are well-planned systems of valves to control and divert water to all the necessary components, effects and details. These are situations in which valve choice is, in fact, critical to hydraulic-system design. The many types of valves can be separated into three specific categories roughly according to application. There are some that divert water, others that isolate water and still others that
The Shenandoah Valley of western Virginia is one of the most beautiful places I've ever been. The site to which we were summoned in January 2004 - a 220-acre estate set amidst its rolling hills - confirmed that opinion in every possible way by offering incredible views of nearby valleys, forests, farmland and mountains. We'd been called to take over a grand-scale swimming-pool project, one as outsized as the property with respect to scope and complexity - and one that required constant, detailed interaction with
