- The water is run through a dry well. This gets rid of the moisture and
- leaves the remaining solid wastes to continue into the septic tank. For
- some reason, the new thing is to use a drain field instead of a dry well.
- It performs essentially the same function.
-
- Yes, detergents, toilet paper, and anything else you put down the drain
- pollutes. This is just a fact of life. Unless you can charge outrageous
- fees to collect money or pay the same, you just can't economically
- afford a super duper scrubber system that reduces your waste output
- to clean water and a bunch of dry powder that gets shipped to a land
- fill and BURIED just like metropolitan areas.
-
- Now, in a normal situation (assuming that you don't have an unusually
- high water table or some other nasty complication), the septic tank
- as a sort of underground compost pile/storage tank. Sewage does leak
- out into the surrounding area. Assuming that you don't regularly poor
- industrial toxic waste down your drain, the surrounding dirt will
- clean itself just like it has done for thousands of years.
-
- If you're worried about detergents, then perhaps you can suggest
- a nontoxic detergent or whether the guy in Japan has managed to
- market his sonic clothes washer yet or something else. I know of
- a certain laundry facility very near here which would be VERY happy
- to know of such a thing as they're busily paying big bucks cleaning
- up the area (oh, you mean running 40 washers with one drain will
- actually saturate the area around the drain faster than the soil
- can clean itself? Imagine that).
-
- Detergents are a problem, but except in cases of severe problems, I
- am unaware of this being a major thing to worry about. It does become
- a major problem when the density of wells and septic tanks (and
- houses) gets past a certain point; then a waste water and well water
- treatment plant becomes necessary (in a city).
-
- In rural areas, the #1 biggest problem that seems to pollute water is
- heavy nitration done by farmers on their crops. It's another matter
- of a little in moderation, too. Too much nitrate solution will
- pollute the water supply, but a little in moderation is not bad.
- Pesticides and herbicides are another example. Some of them stay
- around a long time (example: DDT), while some leave almost no
- residue behind at all (example: Roundup herbicide).
-
- In other words, as before: as long as your well is at least 50 feet
- from the septic tank/dry well/drainage field and a water test comes up
- negative, don't worry about it.
