These working notes were prepared by a manufacturer of sluiceroom and medical equipment in an effort to provide an unbiased comparison between disposable and re-usable systems for human waste disposal. Blank spaces which will be found within the tables and graphs are for the insertion of your own specific local data. Thus, it is hoped that individuals will find these notes to be specifically relevant to them.
