Call me a dreamer. I want to flush with rainwater. Rain barrels already anchor my downspouts. I want to hitch them to my toilet tank. It would save me money and leave my city’s drinking water for better uses.
Yet so far local plumbing rules aren’t helping me, or thousands of others, make the rain-barrel connection. It’s not so much that rules prohibit it, but that even local authorities do not really understand what the rules mean. A little clarification -- and publicity -- would go a long way.
Already, outside my house in Seattle’s Ballard neighborhood, I’ve managed to irrigate my Victory Garden all summer from nothing but the 500 gallons of rain I collect in 10 barrels. During the other three seasons, though, the garden doesn’t need extra moisture, so my barrels sit unused and, often, full to the brim.
So I’m flushing my toilet with pure, treated drinking water that’s piped scores of miles from the Cascades while I’ve got hundreds of gallons of free, naturally delivered, and naturally replenished rain stockpiled just outside my bathroom wall. Perhaps you now understand the intensity of my dream? A Rain Water Toilet Flush system (RWTF)!
