6 History of Water Supply & Sewage Disposal in Hamburg 1842 Great Fire of Hamburg commissioning of William Lindley 1848 Foundation of "Stadt-Wasserkunst" Hamburg first centralised drinking water supply 1892 Cholera epidemic, 8600 dead 1893 First Elbe water filtration plant Kaltehofe starts operation 1912 First sewage treatment plant starts operation in Bergedorf 1924 Foundation of "Hamburger Wasserwerke GmbH" 1961 Start of operations of Köhlbrandhöft sewage plant 1964 Hamburg's drinking water is supplied exclusively through ground water 1995 "Hamburger Stadtentwässerung AöR" is founded 2006 HAMBURG WASSER is formed 2009 HAMBURG ENERGIE is founded Slide 6

7 Services in the Hamburg metropolitan area Drinking water supply areas and sewage water discharge area Slide 7

10 Sustainability and Mitigation of Global Warming Objectives HAMBURG WASSER is energy-self-sufficient by 2018 HAMBURG WASSER works on Zero-CO 2 -Concepts HAMBURG WASSER works on new concepts to reduce water consumption HAMBURG WASSER promotes decentralized stormwater management Project Examples Concept for Energy-self-sufficient water and wastewater treatment Energy from Waste Water New Concepts for Urban Living: Zero-CO 2 -Concept Hamburg Water Cycle Stormwater Management Slide 10

11 HAMBURG WASSER is energy-self-sufficient by 2018 Since 2011 HAMBURG WASSER s carbon-neutral production of electricity and heat on its own grounds levels the consumption of the WWTP. In 2018 HAMBURG WASSER s carbon-neutral production of electricity and heat on its own grounds will level the consumption of the whole company. CO 2 -emissions by 2018: < 1000 t/a vs t/a in 1990 ( t/a in 2009) Slide 11

12 Way to an Energy-self-sufficient HAMBURG WATER Energy balance WWTP and Water Works Slide 12

13 Way to an Energy-self-sufficient HAMBURG WATER CO 2 -Emissions (electricity, heat, automotive) Slide 13

14 Measures at HAMBURG WASSER Using the energy gleaned from waste water Savings per year: CO tons Energy generated by the heating system per year: 2 million kwh Slide 14

15 Measures at HAMBURG WASSER Communal heating supplied by excess heat generated through clarification processes Three external buildings in the vicinity are heated by excess heat from the clarification plan 100% energy from excess heat generated by the clarification process Replacement for expensive burning fuel Savings per year: CO tons Energy generated per year: 2 million kwh Slide 15

16 Measures at HAMBURG WASSER Biogas refined into bio-methane Biogas from the clarification plant at Köhlbrandhöft is refined to produce biomethane Bio-methane is fed into the public gas network Bio-methane is used to power the HAMBURG WASSER fleet of natural-gas vehicles Savings per year: CO 2 3,200 tons Energy generated per year: 16 million kwh Slide 16

17 Energy service cooling (and process water) Low temperature from raw water used for cooling process Delivery of process water Slide 17

19 HAMBURG WATER Cycle in Jenfeld Revitalization of the former Lettow-Vorbeck military barracks into a new urban district Development goals: High quality living Family-friendly surrounding for living and working Positive impulse for the district Jenfeld Ecological approach Land allocation: Habitation (60%) Trade and commerce (20%) Green (20%) Slide 19

20 HAMBURG WATER Cycle in Jenfeld The designated territory in Jenfeld Slide 20

21 HAMBURG WATER Cycle in Jenfeld HAMBURG WATER Cycle Characteristics water concept Separation of waste water streams and separate treatment on site: storm water grey water black water Storm water management and rainwater harvesting as an urbanistic element Slide 21

22 HAMBURG WATER Cycle in Jenfeld Vacuum toilet and vacuum sewage system less flushing water less odors flexible piping network unknown sound higher investment costs Slide 22

23 HAMBURG WATER Cycle in Jenfeld HAMBURG WATER Cycle Characteristics water concept Grey water collection and treatment (trickle filter/ membrane technology) Transport of black water by use of vacuum technology Black water with toxics and resources remains concentrated. Black water recycling enables digestion of other biomass and therefore production of energy on the spot (zero CO2). Slide 23

24 HAMBURG WATER Cycle in Jenfeld HAMBURG WATER Cycle - Characteristics energy concept Combination of waste water treatment with renewable energy production Local heat from the combined heat and power plant for one share of houses Geothermal heat und solar energy for the other share of houses Slide 24
