What better way to study inventions but to design them yourself? What better way to learn how easy it is to recycle water than to design a drainage system that enables every student to water plants when they wash their hands?
I am bursting with hope for the future to announce that our third and forth grade gardeners have sucessfully designed and implemented a beautiful and functional greywater system off the wasted art room sink water. Where once a drain poured perfectly useful dirty water into the gravel now lies a bamboo french drain irrigating 10 feet of space.
The greywater system is a school-wide effort. Seventh and eighth grade gardeners harvested and hauled old-growth bamboo from a friend's coffee farm. Third and fourth graders worked with IPCS Fascilities Specialist Alex Garcia using a simple wedge to split in half longways yellow-with-green-stripes bamboo the circumference of my thigh and approx 8 feet long. Students loved seeing the power of the humble wedge at work. Mr. G brought the ever-popular power drill so students could take turns drilling drain holes the legnth of the bamboo. And students lined up patiently for their turn with the awesome power sander for the smooth finishing touch.
Another class of third and fourth grades carried the bamboo to the greywater site. They hacked out spider lilies taller than they are with the efficency of a herd of beavers. Students dug a trough to lay the system's pipe, connected the bamboo to the sink drain pipe, and turned on the facet for a test run.
But alas, like any new invention, it did not work right at first. Too wide were the holes, too tall were the segment separaters in the bamboo, and not enough slope prevented water from trickling more than five inches.
I was amazed that within a few powerful seconds of thought, more than one inventor noted that added height would work with gravity to push more water down the bamboo and rocks could easily help plug the holes. We rigged up a support system for the drain connector and dug a trough to help stabalize the bamboo pipe.
Our whole ohana can see now how simple ingenuity can help recycle water. Using greywater efficiently will be a huge resource in upcoming decades. With these inventors at the helm of our country, we should be able to incorporate greywater systems into the everyday fiber of our existance.
