I do not want a septic tank for a variety of reasons. Help me hash this out cause I think I have come to a solution. 1) Composting toilet (certain models are "legal" and they have a list.) 2) According to the county guy I spoke with today, in that area they only consider kitchen sink and dishwasher water to be blackwater (toilet stuff too but that is covered by the composting toilet)(laundry water is considered grey water if it is used extensively for diapers, etc)(laundry will be done in the kitchen sink anyway) ---The house is on a hill in the woods. I won't have a dishwasher. The kitchen sink is on the side of the house that faces the downhill and we will be building a front deck off of that part of the house. I am thinking to run a drain from the kitchen sink to plastic 55 gallon drums placed under the deck. Since they will be on the ground and downhill from the kitchen they will be gravity drained. Since they are under the deck they will not "clutter" up the place. These plastic drums will be joined to each other by pvc pipe and will be a storage system for the kitchen sink drain water. However often is needed we will attach a pump to one of them and drain them all into 55 gallon plastic drums placed in the back of the truck. We will drive them to the local car wash and dump them down the same system that all the kitchen sinks in town are connected to. It costs the car wash operator nothing more for us to do this since they are never charged on volume for drainage. We might consider buying goodwill though. That method will dispose of the kitchen sink water. 3) laundry water, bathtub water and bath sink water are considered grey water.(see exceptions above on the laundry water thing and the fact that I will be doing laundry in the kitchen sink anyway) ---Greywater system to the garden by gravity flow with a lint trap on the end of it. (required by regulations) other info: The house is on a hill in the woods. I like the tress (I am the Lorax, etc) and do not want to have to make a clearing for a septic tank and worry about tree roots growing into it. This system seems simple, cost effective and non-harmful to the environment. Water to the house will be from pvc pipes run to the creek and pumped up to the house, also stored in 55 gal plastic drums along with rainwater from the roof, pumped into the kitchen and filtered. (until we get a well) Since I own more than 10 acres, I am exempted from regulations requiring: permits, inspections, planning documents, and an installer submitting info. I am going to call the county guy back tommorrow and run the "hypothetical" idea by him. What do ya'll think first?
