Water conservation report 2010-2013

Water Act 2003, S81(3)

“After the period of three years beginning with

the date on which this section comes into force,

and after each succeeding period of three years,

the Secretary of State must prepare a report

about the steps taken by him under this section,

and about any such steps which he proposes to

take.”

Ricardo-AEA approach to support Defra:

• Questionnaires

• Interviews

• Literature review

Defra edited the draft report provided by Ricardo-

AEA to produce the final, including a forward-

look.


• Key points

– Benefits of personalised in-home advice to enable the greatest water and energy

savings; utilising ‘moments of change’ to introduce or reinforce water efficient

behaviours

– Need to carefully apply any high level messaging on water efficiency

– Understanding water use practices rather than attitudes, behaviours or simply

volume used

Developing the evidence base


• Defra report includes a forward look

• My thoughts

– PR14 and the challenge of delivering large scale water efficiency programmes

– Continuing the collaborative water efficiency fund – strategic research

– Review and update evidence base – needs to be functional to support Water

Companies and policy making

– Water Resources Management Plans 2019 and integrating a new range of policies

– Answering some of the remaining questions from Walker Review – who is

responsible for water efficiency?

– Transitioning to Water Sensitive Cities and learning from

international experience

What next for Water Efficiency?


Future transitions
