10. Backlund ApS has considerable experience with
large water and wastewater projects. In the
beginning of the 1990s BACKLUND represented
KRÜGER - now VEOLIA in the eastern part of
Germany and succeeded getting very big orders
establishing and running water and wastewater
treatment systems including water pipes and
sewers organized in a “Kooperationsmodell” or a
“Betreibermodell”. Unfortunately often
“Mercedes Solutions” with to large and to central
systems.

12. Experienced Problems From Rural Area
Work In Eastern Germany 1989 - 1993
High Subsidies Building CWWTP
Very High Subsidies Establishing Sewers - Up To 95 %
Costs - Up to Euro 50000 to Connect one House
”HOAI” 10 % of Total Cost
Mastering the Art of Tendering
PPP ”Betreibermodelle” & ”Kooperationsmodelle”
Not Supporting Innovation & Visions about Ecological
& Economical Sustainable Sanitation

Waste Reducing Handling Systems in

17. In ”The Action Plan to promote Sustainable Urban
Renewal and Wastewater Treatment” from 1998
and forward BACKLUND worked with two themes:
Ecological Handling of Wastewater in the Country
Nutrients from the City to the Country

25. ● Human Urine contributes with about 80 % of the load of N*
and 50 % of the P* load of conventional domestic
wastewater
● Human Urine treated conventional requires large amounts
of energy producing large amounts of sludge

26. ● We Excrete most of the Nutrients we Consume
● Human Urine contributes with only 1 % of the Volume of
Household Wastewater but contains 80 % of N*, 55 % of P*
and 60 % of K* and less than 0.6 % of Cadmium and 0.06 %
of Lead

27. •One Person Excrete 1 KG P/year.
•0.7 KG in Urine and 0.3 KG in Faeces.
•Human Phosphorus Returned to Soil Would Cover 80 % of P*
Demand
•In Agriculture Short of Phosphorus Human Excreta could be
a Golden Opportunity.
•In 100 years Phosphorus Could Be Gone.
