a very simple greywater system?

i want to know if there is a packaged greywater system that can aerate the water and use it on the lawn and garden. like the greywater gets pumped out through a filter and stored in an aerated tank. i already looked at re water systems, aqua2use, floatender and clivus multrum. i need a simple one that can take kitchen sink water to. i know the clivus one can do kitchen and dishwasher.

The simplest graywater system is to run the drain water from whatever it is directly in an unbranched, downhill pipe or hose of 1 inch diameter out to a mulch basin....a pit or trench filled with mulch or wood chips....around which you plant useful plants needing moisture and tolerant of alkalinity, etc. Set up a separate one for each gray water source. Anything more than that seems a veritable nightmare of complicated plumbing....and hardly worth the effort for the yield of irrigation water obtained. On any homestead growing a significant amount of food in anything but the rainiest climates, you will readily conclude that the use of water for irrigation exceeds all other household uses of water by at least a factor of ten....
