Project area
Total area 5,4 ha (54.000 m²)
At the outskirts of Lübeck
Good infrastructure (School, Shopping, etc.)
Low distances to highway and station
Characteristics
Buildings designed as low energy consuming houses
Ecological materials have impact on energy and material flows during buildings life cycle
All consumption data of the houses are known because of the installation of meters
Infrastructure system is operated by a private company and recharged by fee calculations
Here focus only on water and wastewater related issues.
4
Project‘s History
Residential area in the city of Luebeck (Atot = 5.4 ha)
Project was a winner of a competition in urban development for an ecological housing estate (1995)
Integrated infrastructure system was one of the key issues for the decision Private operating infrastructure
company
(operation of wastewater treatment system and
operation of all other medias supplying the houses)
Project started in 1999 designed for 117 units
Interruption at 30 units in 2000
Operation of the infrastructure systems since 8 years
Flintenbreite (design phase I)
Ecological Housing estate for approx. 350 inhabitants
Integrated inftrastructure system
Planned: 45 terraced houses 56 flats 12 twin houses 4 flats in the central building
Central building for the technical facilities and a meeting room
Private company for the infrastructure system (infranova)
5
Specialities I
Private area
Own infrastructure system and operation company
The system of the integrated infrastructure is part of the development plan
No connection of the houses to public systems (water, energy, wastewater etc.)
House owners have only contracts with the private company not with public suppliers
Own calculation of the operation costs for the inhabitants
Wastewater system with the intention of low water consumption and the reuse of nutrients (as fertiliser)
Current
Situation
Infrastructure is mainly finished
26 terraced houses 12 twin houses Central building with 4 flats
116 inhabitants
All facilities for the technical operation are finished and in operation since 2000
Ongoing: Construction of 46 terraced houses and 12 flats

Expected results for the biogas plant in
Flintenbreite
• Energy production from blackwater:
45 kWh/(p*a)
• Energy production overall
=> 18 MWh/a (45 MWh/a with additon of
organic waste)
5 - 10% of the overall energy consumption
can be covered by the biogas plant

Conclusion
Source separation very effective
Most of the inhabitants recognize the benefits of the
vacuum toilet-system; development of the toilets is
wanted
Experience may decrease the effort for maintenance
Minor technical modifications of the vacuum system
have been necessary
Operation costs of integrated infrastructure system
approx. 20 % lower than for conventional system
(Lübeck Flintenbreite)
Potentials
Saving of drinking water by the use of vacuum-toilets
and installations with less water consumption
Utilization of the energy of the blackwater with the
biogas technology
Utilization of the nutrients from the blackwater and
biowaste after anaerobic treatment
Very low effluent values of the greywater after
treatment
Very efficient separation of the nutrients
