This paper is a follow up of one presented by Otterpohl et al. (1997) in Wa
ter Science Br Technology. This extension emphasises the responsibility of
the professionals in waste- and wastewater management for future developmen
t. It shows a lists of 10 technological options for sanitation with source
control. The political discussion about future sanitation systems seems to
lack input of those working on further development. Even Agenda 21 is a com
plete failure in this respect - sadly, in a core subject for survival of fu
ture generations. The main task of sanitation besides highest hygienic stan
dards is to keep soil fertile.
Sanitation with the mixing up of food and water cycles washes all those sub
stances out to the seas that are extremely harmful there (accumulation) and
extremely necessary on the land (depletion of fertility and fossil resourc
es). New integrated sanitation and waste management systems will mostly hav
e to respect different qualities of matter from human settlements: blackwat
er with biowaste, greywater, stormwater runoff and non-biodegradable waste.
Based on this distinction, nine differentiating and one mixing systems wit
h resources management are presented. Some of them require careful examinat
ion in selected pilot projects. (C) 1999 IAWQ Published by Elsevier Science
