Tom Connolly : Could you see if you could find that video again?
My quick thought is, if it was run through a rudimentary filter bed of Aquatic Plants- cattails etc. like for a grey water recycling set up, it could definitely go for plants
After that, I think I would probably use my nose to tell me if that flow
should be allowed to soak into the ground, or run to a duck
pond.
I Googled ''Rainwater diverting downspouts pictures'' and got lots of devices that are setup to divert trash, bird droppings and other stuff before it goes to a barrel/
tote/holding tank! For the grey water set-up above, a syphon hose to slowly let the full barrel drain through the Aquatic plants should enhance that operation-
Eventually the barrel bottom will gather some detritus .
A few of the
local Amish have some elaborate systems that fill a
bucket attached to a pulley, as the bucket fillsand gets heavy it sinks and part of the downspout is
shifted to a separate fill pipe and a holding tank/ tote.
Older houses from the 1800s to the 1920s have sys terns in the basement to hold the rainwater is is NOT hard water and was prized by the early housewife for wash
day. When that ran out, it was spring water hauled up from the
milk house down to the barn!
Washing the roof with the 1st of the rain, then collecting the clean(er) stuff would eliminate most of my worries ! Big AL
