  • The demand for water is outstripping the supply
  • Less words
  • Problems?
  • We split into teams and worked in pairs, we worked well this way. With 3 meetings scheduled per day, it ensured everyone was aware of the goals.“If you want to know more about group 4, follow our blog!”

    1. 1. 1MAINTAINING WATERSUPPLIES IN THELONDON AREASupervisors: Dr. Neil Mcintyre, Ed Gower & Dr. James LauGroup members: Maximilian Vollmar Theocharis Tofis David Clarke Evdoxia Nikolaou Mithila Patkunan Alastair Courtney Hemal Malde Issam Ashur Jai ShahGroup 4
    2. 2. 2Background - Context• The south east of the UK has always been the driest.• Annual rainfall totals have been fallen year on year in the area around London.• Reservoir levels have been falling.• Severe drought expected in the next couple of years.
    3. 3. 3Design Brief• Reservoirs in the Thames Water region have reached critical levels (25% of capacity)• Short-term and long term solutions required• Creative ideas encouraged• Sustainable for approximately 3 months• No budget limitations
    4. 4. 4Thames WaterCustomers:8,800,000Predicted toincrease to10,000,000 by2035Consumption:165L/head/day
    5. 5. 5 1. In depth quantitative research of Lower Thames reservoirsWork to date 2. Demand modelling 3. Idea Generation 4. Statistical analysis using Matlab 5. Development of viable solutions 6. Final recommendation (Presentation to client)

    7. 7. 7Magnitude of the Problem• Olympics – 500,000 additional visitors to the capital• Below 15% of reservoir capacity, water is no longer palatableDrought Scenario Return period Demand for different lengths of [years] drought [m3/day] 75 days 50 days1976 129 666,931 333,2182006 7.6 539,475 205,7622009 3 259,539 0

    10. 10. 10Solution 1 : Waterbags• Uses the ocean to transport water• Spragg Bags: • Dimensions sufficient enough for large volumes of water • Range from 30Ml to 0.5Gl
    11. 11. 11Presidence • Easy manoeuvrability • Connection of bags into ‘trains’
    12. 12. 12Solution 2 : Tanker• Established method• Tanker capacity = 40,000m3• Cost per shipment = £203,000

    17. 17. 17Short-term Conclusion• Less severe drought scenario: • Bulk sea import by tanker • Bulk sea import by water bags• For the worst case scenario: • Seafaring Desalination Vessel• Recommendation: • Combination of Demand reducing strategies and the flexible Seafaring Desalination Vessel
    18. 18. 18Critical Session Feedback Issues for future consideration • Location of desalination vessel questioned • Environmental issues • Timescale of implementation • Political issues • Value added
    19. 19. 19Long-term SolutionCritical 5 Step Plan1. Identify potential routes2. Advantages & disadvantages of each route3. Nature and scale of engineering works4. Costs, resources & time required5. Technical, social, geological and environmental risks of each route
    20. 20. 20Moving ForwardWeek Goals1 • Research & propose 3 short-term solutions ✓2 • Address client requests and concerns • Initiate long term solution plans3 • Integrate short-term solution into long-term solution4 • Finalise design5 • Address client requests and concerns for long-term solution
