� Adaptation to climate change, demographic chance, etc.
Paradigm change in water supply and waste water dis posal is imminent
Rethinking wastewater management and energy production for cities of the future
food� Nexus between water – food – waste - energy
� Closed loop approaches for water-, energy- and material flow efficiency
� Use of synergies between different infrastructure sectors
� Use of new technologies
HAMBURG WASSER – Joint competence on behalf of water 2
� Use of new technologies
� New business models for “classic” water utilities
� Paradigm change is implemented in new concepts such as HAMBURG WATER Cycle
Blackwater Greywater Stormwater
Green energy from black water
HAMBURG WATER Cycle – an innovative wastewater conce pt based on source separation

pharmaceuticals qualitative high very low *by using vaccum system
separate treatment and processing is reasonable
Water-saving toilet technology
Vacuum toilet and vacuum sewage system
� higher investment costs� unusual sound
� flexible piping network
HAMBURG WASSER – Joint competence on behalf of water 4
� flexible piping network� less odors� less flushing water (-80%)
International placement of the lighthouse project J enfelder Au
� Largest separating sanitation system in Europe (ca. 600 households)
Green Energy from Black Water -HAMBURG WATER Cycle in Jenfelder Au
� „Endurance test“ for vacuum technology as an alternative to conventional urban drainage
� Professional operation by public utility

ZODIAC Marine & Pool
� 35 ha, 770 accommodation units
� Land allocation:Housing (60%)
Revitalization of former military barracks into a new climate-neutral settlement Jenfelder Au
� Housing (60%)� Commerce (20%)� Green spaces (20%)
� Mix of cultural, social and public functions in land use designation
� to be realized 2011-2016
� Low energy or passive house standard
HAMBURG WASSER – Joint competence on behalf of water 66
house standard (50 – 15 kWh/m²)
� Sanitation-, energy- and zero-CO2-concept: HAMBURG WATERCycle
� Enhanced efficiency in infrastructure services
HAMBURG WATER Cycle – Utilizing fully the wastewater -energy nexus
� Treatment of greywater on-site with the opportunity for re-use
Transportation of the blackwater by use of a vacuum system
Towards sustainable Sanitation –The HAMBURG WATER Cycle in Jenfelder Au
� Transportation of the blackwater by use of a vacuum system
� Blackwater separation enables anaerobic treatment of blackwater together with other biomass: Production of energy on site (zero CO2)
� 100 % residential heat supply; 50 % electricity self-sufficiency with photovoltaic

� Numerous factors of wastewater management industryare in flux, e. g. triggered and accelerated by climate change
Green Energy from Black Water -HAMBURG WATER Cycle in Jenfelder Au
Summary
� The HAMBURG WATER Cycle is demonstrated in Jenfelder Au at the urban district scale:
� Source control: Intelligent integration of wastewater management with energy generation
� Water consumption can be reduced by using vacuum system (-30%)
� Option for water reuse (up to 75% reduction in water consumption)
� System is energy self-sufficient and reaches an energy surplus respectively (zero CO2 concept)
HAMBURG WASSER – Joint competence on behalf of water 9
respectively (zero CO2 concept)
� Nutrients like phosphorus and nitrate can be returned to agriculture
� System is applicable on a big-city scale and can be integrated into existing infrastructure, Flexibility due to decentralized concept
� If you aim for improved efficiency and novel wastewaterinfrastructure in 50 years time, you ought to start today –however, you may already be late...
