The
wastewater disposal and treatment in the former East
German Lands especially in the rural parts cannot be
afforded - in short or medium terms - without small
wastewater treatment units. At present no safe,
sustainable and state of art disposal path does exist
for the occurring septage. |
|
Furthermore
an important volume of septage is still stored in wastewater
treatment plants taken out of order, which, depending from the
storage conditions and the technical standard, potentially
endangers the ground-water.
Next to this volume of septage the former East German Lands
dispose of an amount of new Waste Water Treatment Plants which
are under-utilised. |

These
over-capacities are a consequence of too high assumptions in
the design phase or of a reduction of total load after
construction, for example through the reduction of industrial
devices (industry in the former East Germany decreased after
reunification, i.e. while WWTPs were constructed) and through
a decrease (one third between 1990 and 1996) of the
consumption in households.
|
|
The research and development
programme carried out is meant to closed the gap between the
volume of septage to be treated in order to reduce the danger
for ground and river water and the under utilisation of many
biological Waste Water Treatment Plants.
