Two Letters Re: A Practical Tip on Using Roof Catchment Rainwater
JWR:
In response to today's post, I would like to offer an alternate method
to avoid going outside in the rain to flip the value after five minutes.
Cut the down drain pipe into about 5 feet from the discharge elbow. At the
elbow end install a blank over the opening. Drill a small hole in the blank,
perhaps 1/8th inch diameter, and reattached the outlet ducting to a container
to catch the runoff.
At the above cut in the drain pipe, install a "T" and an ell to move
the water downward into a barrel.
[During each fresh rain shower,] the pipe that is blanked off should hold the
initial water that would contain bird droppings and other unpleasant things
before
it starts
to
run
out the "T" above
into the clean water receptacle. This method gives you clean water for drinking
and dirty water for the garden. Of course run your clean water through the
Berkey before drinking.
I wish I could take credit for this method, but the thanks will have to go
to Mel Tappan. - JH in Arkansas
Jim,
I found a rainwater diverter that
looks interesting.
It can be turned on and off in seconds so you can let the first few minutes
of rain wash the bird poop off the roof before you start collecting water.
I imagine with a rain sensor and a little effort, it could be made to start
diverting water automatically a few minutes after it starts raining. - Matt
