In my studio, I don’t have a sink so I do my washings in 5 gal buckets. I reuse these plastic containers and ask my friends to donate if they have them. I’ve even been known to dumpster dive when I see a container or two that has been thrown out.
Rain comes only infrequently in Southern California but when it does I put out my buckets to collect the run off from my patio. I use the water to clean my studio, my hands, clay tools, etc. Extra water is used to water the plants and yard. When you don’t have a sink, it makes you conserve the amount of water you use and forces me to reuse the water until it becomes too muddy for clean up.
When that happens, I set the clay water in the bucket aside. The heavier clay will settle to the bottom and the clearer top water is used to water the grass. The heavier sludge at the bottom is left out in the sun to dry out. It takes several weeks for this to happen. The dried out “cake of clay” at the bottom of the bucket will pop off rather easily and can be disposed of in the trash. This way, you keep the clay out of the sewers and your drain pipes.
