It is possible but probably expensive or hard or both.
You’d be surprised…
Well, what if it was live?
Now you’re getting somewhere!
Skip the sand and the UV and the snails. Definitely skip the fish pond… You don’t want anything in your drain going into a body of water with large vertebrates in it. You don’t want animals to be involved in the filtration process at all.
You want plants. Plants, and bacteria. You want to inject the water into a large patch of vegetation and topsoil, where friendly little microbes will consume all the biologically active material, leaving the ground water to percolate through biologically inactive, mineral earth and back into a deep, underlying aquifer whence that water originally came.
You’re inventing a “septic system”.
You’ll want two tanks. The first will allow solid materials to settle. Anaerobic bacteria will act on solid biomatter, breaking much of it up into soluble effluent. The effluent at the surface overflows into a second tank, where more settling and more bacteria continue to decompose it. Next, the water from the surface of the second tank overflows into a leach field, where perforated pipes release it into topsoil. Here, decomposition switches from anaerobic to aerobic, and the process is similar to composting. The subsurface compost becomes fertilizer to surface vegetation, and the remaining water percolates into the ground water, and ultimately, the aquifer.
