For professionals who tirelessly commit themselves to excellence in all aspects of their work, challenging projects are the butter on the bread. At Drakeley Swimming Pool Co. of Bethlehem, Conn., we truly enjoy jobs with higher-than-usual degrees of difficulty because they generally involve us with clients who have strong ideas about what they want, force us to develop solutions to unique and interesting problems and see us perform on a level that invariably makes us proud. As we see it, these jobs are the reward we get for years of focusing on doing our absolute best. True, these projects can be tough, but we’ve found that by sticking to our “quality without compromise” philosophy, we’ve managed to thrive through tough times and have always earned our share of interesting commissions. It’s proof of the old adage that good things follow hard work, even in a soft economy. That was certainly
If you’re like most people, you probably don’t give much thought to where the water we drink originates. Our supplies of this precious commodity are so reliable, ample and safe that we mostly just go to the tap and use what we need. I was once that carefree, but no more. As I see it, ignorant bliss is actually inexcusable these days, not only because each of us needs a ready supply of potable water to survive and maintain the quality of our lives, but also because
{Multithumb} Ever since people decided to contain and control water for recreational and decorative uses, there have been competing ideas about how to treat it so that it remains safe for human contact. That environment has become even more intense in recent years, as questions and concerns have arisen about the continuing use of traditional chlorine chemistry to get this important job done. Today, for example, we hear a lot about “natural pools” – systems using plant material to absorb the nutrients that feed algae and bacteria. There’s also ozone technology, which needs to be combined with stabilized halogen to treat water effectively. Then there are copper/silver ionization systems and their cousins, the saltwater chlorinators, which have taken root and gained support in many quarters. My career working with alternative sanitizers began a few decades ago. About three years ago, my firm – Fluid Logics of Upland, Calif. – entered this arena with the thought in mind that the watershaping industry needed to take a broader view of the last of those alternatives, digging back through the 100-year history of electrolytic chemical generation and expanding the capacity of these systems to oxidize organic compounds and sanitize the water. For several years before then, I had
I was out of a job in Gloucester, England, several years back when I came across a collection of wonderfully unusual sculptures that changed my life. These compositions, called Flowforms, were the work of British sculptor John Wilkes, an inspired artist who for most of his professional life has explored ways to use water’s nature and characteristics as his medium. I was immediately drawn to what I saw: I’d worked as an estate gardener before being trained as a sculptor at the St. Martin School of Art in London and had always had an interest in natural forms and all sorts of experimental media. I had also spent a good part of
It seems that everyone’s talking about “sustainability” these days, with the usual thought being that, as exterior designers, good environmental stewardship must be one of our main missions. But what is sustainability? What do watershapers need to do to encompass this philosophy? As important, what does it mean to our clients, and where are they in all of this? According the numerous sources I’ve consulted, sustainability is defined as striving for the best outcome for both human and natural environments, now and well into the future. In other words, it’s about
I may be revealing a professional bias here, but ozone is fascinating stuff. In nature, it's among the most essential chemicals on the planet, existing most prominently as a gaseous component of our upper atmosphere. Formed there by sunlight's reaction with atmospheric oxygen, it collectively constitutes the famous Ozone Layer that protects us from the sun's ultraviolet rays and is crucial to the very existence of life on earth. Closer to the ground, ozone is widely used across a broad spectrum of applications. It's well known in the pool and spa market as a water sanitizer, for example, either as a chlorine alternative or an adjunct. It's also widely used in food processing and municipal drinking and wastewater treatment systems and plays key roles in the production of cosmetics and with air freshening and purification systems. For all that, one of the most interesting applications of ozone-generating systems in the past 20 years - and the subject of this article - is the use of ozone in the life-support systems for aquatic animals held in captivity or for
Local historians claim that the image of Philadelphia's Fairmount Water Works was the most reproduced of any industrial site in the United States through the first half of the 19th Century - and for good reason. At that time, the facility represented the absolute state of the art and served as a major point of pride for local residents as well as a source of fascination to visitors from near and far. Throughout its long history, the facility was indeed at the leading edge of water-delivery technology and is now the ideal place to capture and tell the story of the development of environmentalism in the 19th and 20th centuries. The story begins
Composition of this article began with an e-mail I received a while ago from a colleague working in Australia. "What," he asked, "is the maximum allowable depth for a fountain in the United States?" As simple as it sounded, when I took the time to research the issue I found that there was a noticeable lack of definition. I took the next logical step and called various people I know in the watershaping industry and asked them the same question. Surprisingly enough, nobody could point me to any code, regulation or standard that defined what depth a waterfeature's pool could
It was a rainy Wednesday morning in January when I first toured the Clearwater Marine Aquarium. I was on hand to inspect the recent installation of a pair of our horizontal sand filters for the facility's marine-mammal pool and see just how well the pool-filtration products were faring in this somewhat unusual (but not unheard of) application. Located on Island Estates in Clearwater, Fla., the aquarium was bustling with activity from the moment the doors opened at 9 a.m. On this day, a group of pre-school children had arrived to see the aquarium's newest dolphin, Presley, and his friend, Panama. The staff also explained to me that the aquarium, like other indoor attractions, is always busier when the rain falls. I joined right in with the crowd, fascinated by everything I was seeing. My guide, the aquarium's director of life support and marine facilities, Bill Meier, led me to the marine mammal pool - currently home to Presley and Panama but with the capacity to hold several more. This was the vessel on which my company, Pentair Pool Products of Sanford, N.C., had installed the sand filters. As I watched the children's faces as they in turn watched the dolphins, I began to realize that we were
