Thread: Designing a rain harvesting system

    Default Designing a rain harvesting system

    One of the first steps to water collection is the gutter system, and I came across an article a while back in a free magazine they sent to my architectural office, called "Residential Architect". They have an online version here: www.residentialarchitect.com

    Quote Originally Posted by Residential Architect
    Eggleston Farkas Architects practices in the Pacific Northwest, where precipitation is a constant companion, so the firm is continually exploring ways to celebrate water and its conveyance. “We like to look at how gutters and downspouts can work with the architecture,” says Allan Farkas, AIA.

    The Port Hadlock Cabin is a perfect example of the firm's objective. Located on a sloping site with a wetlands area, the 1,965-square-foot retreat consists of two volumes: a main house with a bedroom, living area, and screen porch and a guest wing with a bedroom, loft, and playroom. Each volume is topped by a corrugated metal shed roof that slopes to a shared gutter. The firm rejected a conventional water-collection system, however, in favor of a creative design inspired by one firm co-principal John Eggleston, AIA, saw while traveling in the Caribbean.

    First, the architects designed the roof of the smaller volume to hang over the larger building by roughly 12 inches, creating a covered exterior walkway between the two buildings. They then cut away about 1/8 of the circumference of a large pipe and attached it to the main house with 12 brackets. Each strap is sandwiched between the 2x6 rafter tails of the main house and attaches to the underside of the guest wing's roof framing. “It's a simple hot-dipped galvanized steel pipe, but the straps were custom-designed and the general contractor found a fabricator,” Farkas explains.

    A 1-inch-by-1-inch drip tab at the end of the pipe gets the water started. “Otherwise, it has a tendency to run backwards,” Farkas says. The water falls into a concrete receptacle that channels it away from the house into a holding cistern, where it slowly releases to the wetlands.

    After they get done privatizing the water system, it will be illegal to collect even the rainwater that falls on your roof (seriously).

    The Sandinistas already started nailing people for utilizing unregistered wells without paying for the water used, anything can happen with them!

    Might as well have a breath tax, then.

    Unregistered wells is one thing. The water table below your house is shared across the region. Without such restrictions, there's nothing stopping an individual from pumping the water table dry to irrigate their fields and leaving their neighbors with nothing.

    Collecting rainwater, however, is a new twist on the privatization of public utilities game. I'll have to look for the references another day when I have more time, but it was either Bolivia or Paraguay where a private company (Bechtel) "purchased" control of the water utility. One of the clauses of that contract was that private citizens were not permitted to collect rainwater as that would be stealing "privately owned" water that would otherwise flow to the rivers and lakes.

    Of course, privatizing the water system brought down the Bolivian government.

    Speaking of the river kind, central Florida is trying to siphon off part of the St. John's River for their water supply, and those down river are fighting it, saying the change in water flow will re-shape the ecosystem.

    There's always been a butterfly effect, only now the butterflies are HUGE.

    We're getting to the point where we'll have to have a serious discussion about water allocation. There simply isn't going to be enough to go around soon.

    I don't know what was going on down there, though considering the geography and the size of Miami, it's probably a pretty bad situation.

    Look for Atlanta and El Paso to go dry soon. Then it will get interesting. There simply isn't anywhere else for them to draw from. This is happening to big cities everywhere. It will be the primary resource problem in the 21st century.

    No sweat! 75% of the earth's fresh water is locked up in the frozen ice of the arctic and antarctic and Greenland.... all that will be flowing soon!

    I'm afraid so.

    But diseases prefer a weakended host, so it will probably happen at the tail end of a major war. We're just one Spanish influenza away from going back to a billion people in under a year.

    The pipe system is quite common in Panama. It does a better job keeping the leaves out.
