I've lived with septic tanks (if you get my meaning!) for the last 35
years. At our last house, we had it emptied about every three years, which
seemed to be adequate until the day it started overflowing following a
torrential downpour, which just happened to coincide with higher than
normal use of baths, etc. The clear-up was not pleasant and involved some
expensive alterations. I've gone for annual emptying ever since, which has
been well worth the cost, in my view. I now have a standing order with the
local council and don't even have to remember to ask for it to be emptied.

A daughter lives on a Welsh mountain with a septic tank, they've been there
for at least twelve years and have never had the tank emptied. I thought the
system developed bacteria which dealt with solids and they drained away
harmlessly.

Hers is an organic farm and she is scrupulous about not allowing anything
which would be hostile to the bacteria down the drain. She uses special
dishwasher tablets, laundry and other preparations. There are two adults and
a small child so baths are frequent and laundry is too - she only uses
washable nappies.

When we go we live in our tiny caravan and have to use similar
bacteria-friendly products if we empty into the tank - which we do. When I
use conventional washing up liquid for dishes the waste is poured into a
ditch.

I daren't do anything else!
