Pipes are pipes, right? Anything that moves water from point A to point B will get the job done, so long as it doesn't leak, right? Well, not right, as I discuss in the video linked below. Of all the conceptual advances made within the watershaping industry in the past 20 years, I'd have to say that watershapers' awareness that pipe size really does matter and that big pipes are
In our business, when we talk about people with disabilities, we always put people first: We speak of "people with brain injuries," for instance, or "people with arthritis" or "people with spinal injuries." That's an important distinction, because the language informs the entire mindset needed to help them improve their situations in the most effective ways. For starters, this "people-first" approach helps us avoid misleading generalizations: Often, we find that two people with nominally similar conditions or disabilities will have significantly different needs and that the methods used to treat each may prove to be significantly different as well. Everything we do at the Brown Center, in other words, must be based on the individual's own

Of all the concepts of hydraulic-system design, there are few that have more importance than the correlation between water flow (that is, capacity expressed as gallons per minute) and line velocity (the speed at which the water travels). As water travels through a pipe, its increase in speed (that is, its line velocity) results in an increase in resistance (expressed as feet of head) and in a reduction of end pressure, which is measured in pounds per square inch (psi). In other words, an increase in friction losses and a drop in pressure is the result of increased water velocity at a given flow. If that makes sense to you without further explanation, then you know much of what you need to know when it comes to selecting pipes and fittings and setting up a watershape's plumbing system. If it doesn't, this article will cover the basics - from selecting pipes and sizing lines to
As you spend your days creating structures that contain and control water, it's easy to lose sight of the water itself. Yes, we're conscious of the fact that we have to filter, treat and sometimes heat it, but in its role as the defining feature in our products, water is so familiar a participant that in some ways it almost becomes invisible. This time around, I want us all to step back from the intricacies of the design, engineering and construction tasks we all perform to consider the water itself. As we do, you'll find yourself thinking (as I often do) that we're in a special, healing trade that
