Greywater pond made from six-foot diameter, two-foot deep stock tank in fenced area near our house.
Water flows in underground pipe from indoor washing machine. Desert monsoons added an inch or two of water on Thursday night.
The floating water hyacinths pictured at the rear of the pond, donated by a permaculture friend, metabolize toxins from the water. They are doubling every two weeks.
In the foreground (forewater?): three floating water irises, purchased from a local nursery, have begun to sprout new leafs, as the old ones decay.
UPDATE – OCT 3, 2013: This greywater pond project FAILED. The hyacinths never multiplied fast enough and died off, killed by either the bright summer sunlight and heat, or the greywater and the algae that started to grow (or a combination of all of those factors). Friend’s successful project was in a much smaller pond, in almost complete shade. So it goes.
