I am building a decent-sized pond in my back yard as time/$$ allow-and I'm gonna eventually have my wastewater drained into a 'holding' tank-buried in the back yard. The drain also is used by my ice machine as the old ice melts, it will also drain into the tank. THen I will have an auto-float type device in the pond and it will pump the 'wastewater' into the pond until either the tank runs dry (it will be ran by a sump type pump, whenit has water and the float at the pond gives it power, then it pumps until dry, then shuts off). I will also have a waste type drain where I can either pump it into the pool or just into the yard (wasted) during rainy seasons of extra waste water. I figure I can serve a couple of purposes with this waste water and also save afew gallons in the meantime. it sounds kinda extravagent and difficult, but I can do it for next to nothing and I have the experience to do it--time is my only enemy on that project-lol
