Gray water dumping
by Anonymous

I live on the Big Island of Hawaii - Kona side. We have a cess pool. We never ever had a cess pool before and we have a number of questions.
Today we are cleaning with Dawn dish washing detergent and Borax.
Is it safe to dump the dirty water in the yard or is it better I dump the water in the toilet?
What about bleach?
What about use of a garbage disposal?
Toilet paper best kept out and then what to do with it burn it or land fill it? (We here mexicans in mexico figured this one out long ago - apparently they do not to use toilet paper but if not then what?

We are trying to remediate mold without using hash cleaners but have reverted to bleach known for treating mold/mildew. We are looking into assessing what the best ventilation could be for our situation while we are cleaning. Any recommendations?

What is the best envornmentally sensitve approach as to what to put in and not put in a cess pool?
We are wondering if septic would be more environmentally sound practice?
