Other Waterfeatures (from birdbaths to lakes)

A Splashy Statement
It was the perfect confluence of needs and ideas: Mattamy Homes, a Canadian developer based in Toronto, was working on a project in Edmonton, Alberta - a new community called Stillwater that they wanted to elevate with an "amenity center." This key space, we learned, was meant to promote healthy, active lifestyles by offering residents a play area that would include both a skating rink and a unique splash pad. As planned, the community was set up with wilderness areas, hiking trails and other opportunities meant to encourage enjoyment of the great outdoors. To capture that spirit in the splash pad and playground, Mattamy Homes enlisted the services of Calgary, Alberta-based Park N Play Design, a designer and installer of custom indoor and outdoor recreation spaces throughout Canada. The resulting splash-pad design includes a large, custom-fabricated set of spray rings that provides fun for children of all ages while at the same time creating an eye-catching, artistic visual at the heart of
Dressed for Success
A glance at our portfolio of dozens of golf-course projects dating back to 1990 shows that no two of them are exactly alike - despite the fact that our mission in each case has been exactly the same: It's our goal with every project to leave behind grassy patches that have seemingly been draped across natural terrain that has been there, untouched and untrammeled, since time immemorial. In other words, we've crafted elevation changes, watercourses, plantings and other defining features so carefully that it seems like folks who enjoy chasing little white, dimpled
Moving a Mountain
We've participated in the construction of lots of great golf courses through the years, but this one was something special. It started for us at Pinnacle Design (Palm Desert, Calif.) with a call from one of the world's top golf-course architects, Ted Robinson, Jr., who let us know that we had to rush to prepare a presentation for a client in South Korea. As he explained the situation, if we couldn't win over the chairman of the conglomerate that was building the 27-hole course, the job would go to
Healing Ways
Through the years, Bruce Zaretsky has designed enough healing gardens that he knows just how comforting they can be for patients, caregivers and loved ones.  But they only work, he notes, when designers keep some basic principles and several user-specific design factors in mind.  
Painting in Water
From the start, the systems I call "Graphical Waterfalls" have always been about combining art and technology to create something unusual and visually arresting. As discussed in a WaterShapes article in August 2007 (click here), it was an idea that began in the first year of my professional teaching career at the University of South Florida in Tampa. It became an earnest professional pursuit when I asked a professor in the music department if I could borrow some time on his then-new paper-tape computer to experiment with controlling streams of falling water. That was the early 1970s, and even then I figured it might be possible to create recognizable visual patterns with streams of droplets. The music professor wasn't particularly enthusiastic about my request, but he said that if I saw a way to use it for a musical purpose or at least to create a sound effect, he'd give me the access I needed. Long story short, the work I did in collaboration with some of my students and a colleague in the mechanical engineering department led to development of the first three-dimensional, computer-controlled waterfall. That initial system consisted of a horizontal, four-foot-square array of 64 nozzles - modest, but a good start. BUILDING BLOCKS I continued working with this original system for about three more years and made enough progress so that by 1977 I was able to display the first falling-water graphics - a vertical sine wave and a diamond. The first big leap came when I was given a Project Design Fellowship by the National Endowment for the Arts: I used the support to develop a square, 576-nozzle system that operated off a single modular valve and, by 1982, I was finally able to spell out words. The technology had its modest beginning with this 64-nozzle system. Completed in 1977, it showed a diamond moving vertically through space. A larger system and spelling with letters was funded with a second Project Design Fellowship. This allowed me to develop the networking of four of these 576 nozzle valve modules to form a two-by-two-foot. horizontal square system with 2,304 nozzles. The result was first exhibited at Navy Pier in Chicago in 1988 by the Klein Gallery during the International Art Exposition. The next big leap took the form of a private grant from the Kohler Company: I used that funding to create a 12-foot-wide, 6,912-nozzle waterfall made up of a dozen of my one-foot-square modules. Kohler had offered its support in exchange for an agreement to exhibit my work at two of their national trade shows each year, using equipment I'd made through their grant. That was just the break I needed: Once I went public at a few of these shows, exhibit companies started calling and our graphical waterfalls (called at that time "The Rainfall Project") began appearing at trade shows, both to display marketing messages and to draw attention to booths. As I continued my research in valve design, I always aimed at producing denser, more visible water droplets. By 1983, I assembled my first 576-nozzle module and could produce helical structures that turned as they fell. I'd never considered trade shows as being the outlet or venue for these effects, but off I went - and the great thing was that the sponsoring companies had no hesitation at all about funding the necessary transport, set-up and dismantling of the systems while covering our other expenses. Fast forward about three decades and 160 national and international displays and permanent installations as well as the involvement of other professionals, and we move past dozens of intermediate steps that saw our displays become larger and more visually diverse. Now we've completed the project highlighted below: a cylindrical Graphical Waterfall we fabricated as a temporary installation for the Toyota National Dealer Meeting held in Las Vegas, Nev., in August 2014. To get a sense of what's involved, let's move through the installation process in a stepwise fashion and then, finally, arrive at a video link that shows the display in action. Making Ready The housing for the 16-foot, 4-inch wide Graphical Waterfall system includes 576 nozzles per module hung within a faceted, 16-sided theatrical truss. In all, there are 9,216 nozzles set up in six-nozzle-deep rows. We also attached lighting systems to the truss; they're seen in the image (at left) outside the framework; they were moved inside a bit later on. In all, the upper assembly weighed 8,000 pounds once water was added to the system. With our equipment in place, we made connections with eight one-ton chain hoists attached to the ceiling of the convention center. By this point, we'd threaded all of the necessary hoses into position on the upper truss along with all of the electrical wiring and Ethernet control cables. Shown complete in the middle image, the truss had an overall diameter on center of 21-1/2 feet. With the hoists engaged, we raised the truss to a point 12 feet above the floor as measured from the bottom of the assembly (right). It took two motor controllers to synchronize the chain hoists. This was definitely a precision operation: Everything had to be aligned per plan. To that end, each of the hoist motors was monitored with a strain gauge and all levels were checked with floor-mounted lasers that communicated with the motor-control systems. Tank Technique The cylindrical water tank is actually four 90-degree arcs of swimming pool vinyl draped over prefabricated, U-shaped aluminum forms (left). These are clevis-pinned with horizontal struts to form the inner and outer walls of the cylinder. We also placed four three-horsepower pumps, one behind each of the tank segments, to achieve the target circulation rate of 550 gallons per minute. The top of the cylindrical tank is fitted with PVC arms that straddle the inside and outside of the tank. (We took great care in placing these arms to avoid harming the vinyl liner.) The joints between the four pool arcs are cut down a bit to allow for equalizing tank volumes if there are any fill discrepancies (middle). The PVC arms serve to support polypropylene grills (right). Finally, the tank system is clad in an exhibit shrouding made of plywood covered with a plastic laminate. These are attached to the sides of the tank structure with Velcro - everything specified for easy assembly and even-more-rapid post-event removal. An Uplifting Process With the tank ready, we lowered the cylindrical truss to a level about two feet above the cylindrical tank (top left). Once we were certain that the tank and truss were vertically aligned (obviously an important task!) we filled the tank with water and connected the hoses. The system was then run in place to check for any problems: We knew the entire convention center floor had been covered with new beige carpeting under the plastic sheeting beneath our feet, and soaking it was not an option! With these test runs complete, we started threading our four two-inch-diameter hoses through a single vertical truss, placing it alongside the electrical wiring and Ethernet cabling (top middle left). All of these connections had to fit within this foot-square box, an operation that eventually involved various members of our staff along with some show riggers (top middle right). We knew it would all fit, but dealing with the flexibility of the hoses and cables along with the openings in the truss made for an unusual weaving exercise. We completed this threading process with, in all, three sections of vertical truss, raising the upper assembly another section-length notch each time to put a bit of gravity to work in our favor (top right). The completed height of the waterfall was about 24 feet. With the vertical truss complete and in final position (bottom left), we ran another quick alignment check and used diagonal steel cables to adjust and perfect the radial orientation of the upper assembly. Good to Go We formally initiated the system on the morning of a day that would close with the three-and-a-half-hour opening reception for 3,500 people in attendance at the 2015 Toyota National Dealer Meeting. We spent our time productively, running through the graphics we'd developed and turning them into a complete show. (We couldn't effectively do this beforehand: Although our fabrication facility in Milwaukee, Wis., is tall enough and large enough, the ceiling is not strong enough to take the weight of a system this large.) As the images show, lighting is a key component in the impression these displays make. In this case, Toyota had retained the George P. Johnson Company (Torrance, Calif.) to stage the event. In turn, GPJ hired a company to control the overall lighting system for the show. Our systems include built-in lighting controllers, but GPJ wanted their lighting contractor to manage the entire hall, so we left everything in their hands and worked together very well. High Art Before the Toyota display went into fabrication, we presented drawings to the staff at the George P. Johnson Company (Torrance, Calif.) and to the company that fabricated our tanks. After the show, photos were inserted into the drawings and they were framed for an art exhibition. One major consideration about working primarily in the trade-show world is that everything is so ephemeral: In these environments, a whole lot of work goes into installing a system that operates for the duration of the meeting - never a long lifespan. In the case of the Toyota meeting discussed here, for example, the display ran during the three-and-a-half-hour opening reception - and that was that. There are, of course, some advantages to everything being so temporary and, happily, so recyclable for use in other installations. But it doesn't relieve us of the need to think of each and every project as a permanent installation: We need to size and select circulation systems to meet specific requirements and think through system hydraulics with extreme care. We also have to anticipate and accommodate water losses in our closed systems and maintain proper operating levels with lots of water in transit. Even for this short exhibition, we had to cover filtration needs to ensure perfect performance throughout. It's rigorous work, but it's exciting, too - and incredibly rewarding when you watch the looks on peoples' faces as they stare, utterly amazed, at the fruits of our labors. -- S.P. Within the waterfalls, the water droplets can be programmed in two independently programmable layers that cover three rows of nozzles each in our six-nozzle-deep modules. This allows us to create ribbon forms that can be seen crossing over each other - a very cool effect, especially when lights in the vicinity are dimmed and the system's own lighting takes over. The theme for the event was "Best in Town," which appears in a sequence that also features the Toyota logo, stars (as shown in this article's opening image), dancing water ribbons, a winding road and the show's grand welcoming message (click here to see a full test run of the system's graphic sequence). The scale of the installation is seen in the human figures who pass through the space. Later in the day, crews came through and removed the protective covering from the carpet: After a few days of furious activity, everything was finally ready for the big event.

Community in Action
When New York's Long Island comes up in conversation, most people think about the Hamptons, exclusive summer resorts, incredible estates and beaches by the mile. But that image has a flip side:  For many years, in fact, Wyandanch, a hamlet within the town of Babylon, N.Y., has been a community that has had very little go its way, with poverty-stricken streets, gang activity and not much going on that would make its citizens hopeful about
Liquid Mettle
From the beginning of my career as a sculptor, I’ve mostly given myself over to two simple elements – metal and water – and have tried to develop approaches that turn one into an extension of the other. I like the sense that a sheet of flowing water completes the simple stainless steel shapes I create.  I also like to play with illusion by creating the impression that
Liquid Glass
As a designer and artist, I believe that water and glass walk hand in hand: Both are transparent and translucent. They distort and reflect surrounding colors and forms. And depending upon whom you ask, water and glass are both liquids. The visual and physical resonance between these two fascinating materials is important to me: I know that their interplay adds
Mile-High Gallop
It’s not every day you get the chance to work on a project that’s going to be seen around the world by millions of people for decades to come. That was exactly the opportunity that came our way in October 1999, when we were asked by the Denver Broncos to construct an elaborate waterfeature at Invesco Field at Mile High, a brand-new stadium that
Making Water Dance
These days, clients who’ve been out to see a bit of the world come at designers and builders with all sorts of interesting ideas and requests.  For the most part, they’ve seen something they or their children really like and want to get an appropriately scaled version of the same sort of water effect as part of their own backyard resorts.
