Overall Aim

• MTP aims to reduce the environmental impact of
  products.

No intervention

• For the water products area this means

2005
Supporting Policy implementation to combat the
effects of key drivers causing strain on water
resourcesand ensure minimum waste of water
through the use of water efficient products

Policies impacting on water efficiency

• Government Sustainable procurement (Defra EBC)
• Water Supply (Water Fittings) Regulations (Defra
  WSR)
• Building Regulations (CLG)
• Code for Sustainable Homes (CLG)
• Mandating Water Efficiency in New Homes (CLG)
• Metering in water scarce areas (Defra WSR)
• Identifying area of water stress (EA)
• Water Product Information Scheme (Defra WSR)
• Regional Spatial Strategies (RPB)

5
Progress in 2006/7

• Focussed on WCs, showers, baths
• For each product type
• 2 briefing notes (updated rewritten)
• Actions to improve design and efficiency
• Water efficiency performance tests
• Policy Brief (updated rewritten)
• Impact of policies modelled and possible water
  savings highlighted
• Performance levels required to achieve desired
  impact have been defined (PSIB)

Supporting work items in 2006/07

• To supplement technical data in briefing notes
  and progress action plans, including
• Stakeholder engagement NWCG, policy leaders,
  suppliers, manufacturers, water companies .
• Quick Wins Potential savings by change to Govt.
  purchasing specification for WCs
• Test Standards Reports on current standards,
  developments, gaps and proposals
• Product performance and reliable information.
• Innovation Water savings from very low use WCs.
• Innovation Water savings from cascading water
  use in industrial premises
• 23 Product stock models, to cover showers, baths
  and WCs. Including policy analysis to produce
  Reference, Policy and Earliest Best
  Practice scenario projections forward to 2020.

Potential barriers to achieving projections

• Limited evidence of water consumption product
  performance in new properties
• New product installations
• Retrofit products
• Lack of common test methodologies
• Lack of agreement on future minimum standards for
  products
• Lack of supply chain initiatives
• No consolidated evidence of consumer attitudes to
  water using products

07/08 Programme

Objectives

• To provide the underpinning knowledge base for
  performance standards, to the support the WPIS
  and other policies.
• To maintain an evidence base that covers products
  responsible for over 80 of domestic water
  consumption in homes.
• To consider the life cycle assessment of water
  efficient products, including their impact on
  carbon and waste streams.
• To continue to engage and consult with
  stakeholders from the wider water industry.

14
Current projects

• Maintenance of existing evidence base
• Maintain models, BNs, PBs and performance
  standards
• WCs, baths showers
• Collate evidence model water use for tapware
• Updated evidence base including all product types
  currently available
• New Policy Brief for tapware
• Overview of test methodologies for tapware
• Modelling work for tapware including Policy and
  EBP lines
• PSIB for tapware
• Product area stakeholder workshops
• International experience of product labelling
• Scoping studies for next batch of products

15
Planned projects

• Shower performance criteria and definition
• WPIS Database Phase 2
• Agreeing and adopting test methodologies
• Quantify scope for better ergonomic labels,
  including potential impact
• Energy consumption of rainwater harvesting
  systems
• Impact on carbon of different water
  efficiency/conservation strategies
