Now that I have the kitchen cabinets done (except for the doors ;-) I can get back to the plumbing design, because I know what size/shape space I have to fit it into. That takes me back to the water recycling experiments I started a few YEARS ago, when I built these DIY sand filter buckets to play around with. Originally I was following the work of this guy and his sand filter designs, despite his buckets being about 10x larger than mine.. When I built the buckets the first time I made baffles to go inside, but quickly abandoned because they were so small they got clogged. So, I have done away with the baffles and just used a kitchen sieve like one would use for sifting dry ingredients together to keep the sand in place. My goal is to be able to wash my dishes and get the water clear/clean enough to dump into the tank under the floor. From there it gets pumped through an activated charcoal and a biological filter back up to the faucet to be reused. So, this sand filter step is pretty important.
After eating a whole bunch of good food I have made a mess. So, let's go outside and wash some dishes, see how much water I use to get the job done on a daily basis, and then what I have to do to treat X volume of water. So far I seem to use 3 batches of water: one to pre-rinse, one to wash and one to finish rinse.
This is the pre-rinse water. The total volume I use on average is about 8 gallons of water total.
In the bucket goes my swill.
