  1. Meeting water supply needs - sustainably East of England Biodiversity Forum & EEDA Miranda Davis 27th April 2006

  2. Essex & Suffolk Supply Areas

  3. How to Balance Supply and Demand Forecast future demand • population change, housing, industry, customer behaviours Assess Reliable Yields • Quality and quantity reviews, Environmental studies, licence performance Twin Track Approach • Constrain demand • Source new supplies

  4. Challenges for Water Resource Planning in Essex • One of the driest regions of the UK, prone to drought • Increased demand for water due to new developments, increasing population and changing demographics • No potential for traditional new resource development within Essex, as no intrinsic water available • Major uncertainties posed by climate change, time limited licences, environmental drivers and sustainable abstraction

  5. Abberton Reservoir 32% - November 1997

  6. Demand Management Water Efficiency • Specific initiatives for homes • Industry leaders on the promotion of water efficiency initiatives LeakageManagement • Significant reduction over last 8 years; reached the ‘Economic Level’ (ELL) Metering • Meter penetration in Essex currently 32%

  7. Water Efficiency History • Feb 1996 New Duty to promote • 1997 Watersmart, leading to 10,000 audits pa • 1998-2000 Water Efficient New Homes Project • 1999 Water Forum • Schools projects, waterbutts, hospitals etc • Research project on maximum savings achievable in new homes (technology + behaviour) • Continued programme of audits and projects • Water in Sustainable Communities conference April 2005

  10. The ‘Abberton Scheme’ 2000 onwards Recognised in 2000 that the three schemes that had been investigated since 1992 were effectively inter-related elements of the same scheme : 1. Variation of the Denver/Blackdyke Licences 2. Upgrade of the Transfer Route (EOETS) 3. Raising of Abberton Reservoir and increased storage
