- How pray tell does the solids get into the septic tank if all the moisture has
- been left behind in the dry well? ;-) That's not how a drywell or septic
- tank works...

- The old "standard" drywell system was simply allowing household waste to go
- into a pit of some sort. Often filled with rocks and covered with topsoil.
- Aka cesspools in some cases. These are rarely permitted nowadays because:
-
- - you can't usually pump out a drywell
- - they plug up relatively quickly
- - they put raw sewage directly in contact with the soil over
- a deeper range, and will pollute water tables far more readily.
-
- Drywells (plus agricultural runoff) is why most municipal codes no longer
- permit shallow (surface water/water table) wells. Drywells are little more
- than a fancy name for a pit for an outhouse that has running water.
-
- Septic tank plus leach beds, if cared for properly, can last virtually forever.
- Mainly because you can pump out the solids, and the leach bed converts all of
- the liquids and soluables. And because the concentrations are much lower,
- pollution is less likely. Ie: phosphates in moderation aren't bad. Concentrated
- they make a mess.
-
- Drywells were still permitted here, last I looked, ONLY when the soil
- percolation rate was very high, and it's a long way away from the
- water table, watercourses and wells.

-
- This is absolutely true, regardless of whether it's a septic bed, drywell
- or municipal sewer system. It has to go somewhere. Sewer or bed. And
- one would suggest that a properly operated septic system is probably
- better on the environment than a full blown municipal sewage system.
- Cheaper too. Just not practical on city lots...

-
- Well, that's more-or-less how a septic system works. The water is
- clean after the leach bed, and the gunk, while it ain't dry, does get
- buried somewhere. Just like a municipal sewer system...
-
- >... the septic tank

-
- Good way of describing it...
-
- >Sewage does leak out into the surrounding area.
-
- Raw sewage shouldn't leak out into the surrounding area in a properly
- operating septic tank. The effluent of the septic tank is a very
- much biologically digested almost clear liquid. Which is further cleaned
- and filtered by the leach bed.
-
- >Assuming that you don't regularly poor

-
- With the caveat noted above, yes...
-
- One shouldn't put harsh chemicals down a septic system, because it can
- kill the bugs in the septic tank that break down the sewage. Ie:
- go easy with - preferably avoid - the bleach. No solvents, oils or
- other nasties such as draino. Much as one *should* do with a municipal
- system.
-
- >If you're worried about detergents, then perhaps you can suggest
- >a nontoxic detergent
-
- "low" or zero phosphate detergents to be precise. Ie: Sunlight.
