The Department for Environment, Food and Rural Affairs (Defra) commissioned Collingwood Environmental Planning (CEP) through the Centre for Ecology & Hydrology (CEH) to carry out a rapid evidence assessment (REA) of existing academic and other literature about behaviour change approaches to reducing household demand for water.
The REA is intended to answer two research questions:
What behaviour change approaches have been used to reduce household demand for water and how effective are these approaches?
What key evidence gaps remain in the evidence base and how best could these be filled?
Water companies have a legal duty to promote efficient water use. The main focus for domestic water efficiency programmes or interventions in the UK has been on reducing the amount of water from the public water supply that is used in the home. Behaviour change approaches address an aspect of water demand that is not amenable to engineering, technological or regulatory interventions (Hoolohan, 2015). Common to all behaviour change approaches is an understanding of individual behaviours as open to influence, that is, not fully determined by factors such as engrained cultural habits or technological systems.For the full article click here.
A toolkit to support local authorities and housing associations to work in partnership with water companies to deliver water efficiency. This includes an overview of drivers, an overview of partnership water companies and a range of practical case studies and examples.For the full article click here.
This guidance was developed by SaveWater South East to provide evidence in support of local authorities choosing the optional requirement of a 110 litres per person per day water consumption target in new homes.For the full article click here.
Water efficiency services represent a key benefit from the introduction of retail competition to 1.2 million businesses, charities and public sector organisations in England from April 2017. This research was undertaken from the customer perspective to identify what level of water efficiency services are being offered by new retail water companies.It was undertaken between 13 and 21 November 2017.For the full article click here.
Summary version of the Water Efficiency Strategy for the UKFor the full article click here.
The Water Efficiency Strategy for the UK was developed in consultation with the water sector and launched in June 2017. The strategy sets out recommendations and actions in the following areas:
Water, people and communities
Water Wise Cities - improving water efficiency in our urban environment
Products and labelling
Water company delivery and regulation
Water efficiencyin retail competition
Integrated watermanagement and resilient infrastructure
We know Ofwat is keen to see larger-scale water efficiency and we supported Defra’s expectation that they “promote ambitious action to reduce leakage and per capita consumption”. The key elements of our response included the need to explicitly support variable infrastructure charging schemes linked to water efficiency for new housing developments; to enable water companies to take risks by working in collaboration with others to achieve better outcomes on water efficiency; for wider policy changes to deliver extended and enhanced water efficiency scenarios; to audit the impact of retail competition on water efficiency services and how this might translate to residential retail competition; to consider the potential contribution of water efficiency in upstream competition; and for third party auditing of business plans and final PR19 determinations for progress on water efficiency.For the full article click here.
