Good job Marshall.
I collect all of my chill water and reuse it in the washing machine. This obviously only works for top load machines, but at least feel like I'm not wasting. I do end up dumping my oxiclean solution and of course I go through 5-10 gallons cleaning up and rinsing my kettle and tun.
I've been meaning to try chilling 100% with a sump pump. Sure it won't be as fast as ground water, but with recirculation in the kettle and recirculation of the chill water, I think I can do it with 12 gallons of water plus some ice water.
