Anyone given much thought to gray water recycle? I have been given though to it for two reasons, to have water to always keep the yard green, with a plus side of having a lower water bill. If you dont know gray water.. From what I understand there are 3 types of water, pure (self explanatory), gray (water from sinks, washing machines and dishwasher) and black water (toilet water) You can recycle gray water to use in your toilets or use it outside. I would use it more for outside than toilets, mainly because I like to look at clear water in my toilet haha.. Seems like you could get a 1500 gallon septic tank and plumb your gray lines into it along with even rain water. Come up with some sort of pump system and overflow system and your set. Just wondering what people think.. Or maybe some one has even done it?
