The quickly growing and environmentally aware community of Welby has many residents seeking to reduce their ecological footprint, starting with their homes. Plumbing that is friendly to the ecology offers a variety of benefits, the most important of which is that it helps save water—lots of it. Even with our current water conservation efforts, the American Society of Plumbing Engineers (ASPE) estimates that we are still losing a billion gallons of potable water a day. Picture that water flowing down the Los Angeles River, and you get the idea. Quite simply, saving water saves energy. So of all the things we can do to make our homes greener, saving water (and the energy it takes to make more of it) is at or near the top of the list.
Another eco-friendly plumbing choice that Welby residents might make is the solar water heating system. This system uses solar panels to capture energy from the sun and convert it into usable power for the home. Unlike most plumbing choices, this one allows for the possibility of plumbing that uses absolutely no fossil fuels whatsoever. That's a nice thing to contemplate. Of course, the solar water heating system involves an up-front expense, and in the end, you have plumbing that works just like any other plumbing system, and when you factor in all the possibilities, that seems like a pretty dull thing to make a choice about.
As a final point, think about what it can mean to have a greywater system in your home. What is greywater? It is not the toxic waste of a 1950s science-fiction movie; it is the moderately polluted water coming from your sinks, showers, and washing machines. It can be treated (not as in a monster movie but as in a water-recycling plant), and when it is, the water may be used for nearly anything—except drinking—for a very long time (like when it rains). What I mean is that the water recycled from your showers can be used to irrigate plants in your yard. Water recycled from your kitchen sink can be used to flush your toilet. Although you may not see the bathroom plants in a greywater system sanctuary as very welcoming, trust me: those plants do not give a damn if you are using rainwater, recycled water, or ocean water; they will thrive.
