Domestic water use and conservation (Aquastress
WP 3.3.)

• David Inman
• Cranfield University, UK

2
Objectives

• Understand the risk of domestic water shortages
  occurring in the future
• Identify how water conservation can reduce the
  impact of water scarcity
• Identify policy mechanisms required for the
  successful implementation of water conservation
  tools

3
Forecasting

• Objective 1 Understand the risk of domestic
  water shortages occurring in the future
• Approach
• Forecasting
• Domestic demand vs. water availability
• Household demand by household types
• Include climate change and population growth
  forecasts
• Forecast future water deficit

4
Water savings

• Objective 2 Identify how water conservation can
  reduce the impact of water scarcity
• Approach
• Build database of how water conservation tools
  impact on household consumption in different
  types of household
• Integrate database into the forecasting model
  algorithm

5
Policy mechanisms

• Objective 3 Identify policy mechanisms required
  for the successful implementation of water
  conservation tools
• Approach
• Identify factors which influence the uptake of
  water conservation tools in tests site
• Apply Bayesian modelling to understand
  conditional relationships.
• Identify policy mechanisms which can improve
  uptake of water conservation tools in the
  domestic sector

6
Output

• Forecasting
• Identify the risk of future water deficit
• Forecast how water conservation could reduce the
  water deficit
• Recommendations to
• Target specific water conservation tools at
  specific household types
• Implement policies to promote domestic water
  conservation tools on a regional scale
