Promoting Behavioural Change in Household Water Consumption (2007)

This literature review prepared for Smart Water summarises the principal theories relating to behavioural change relevant to water conservation in residential situations. It considers the application of the theories to actual behaviour change relating to conservation patterns and discusses examples from studies relating to the environmental sector. The policies and targets set by the government provide a base on which to examine techniques and tools available to encourage residential water users to conserve water and change their behavioural patterns. Specific studies on water saving in residential situations in Australia and elsewhere help to determine effective means of influencing conservation of water in Victoria.

Excellence in Metering (2007)

This report provides recommendations on achieving excellence in utility metering. In general, the report is guided by three fundamental perspectives: 1) utility metering is a critical component of data driven sustainability initiatives, 2) increased awareness amongst the university community (either through billing and/or public data displays) will reduce energy and water use on campus; and 3) providing higher resolution data to the utilities staff will enable better identification of inefficiencies, malfunctions, energy/water waste, and opportunities for savings.

Leakage Management Technologies (2007)

In this EPA and AwwaRF report on Leakage Management Technologies, technologies are discussed and trialled in North America. Researchers reviewed proactive leakage management technologies used internationally, with focus on the United Kingdom. The assessment phase identified the most promising leakage management technologies for pilot testing in North America. This report provides guidelines and tools on how to successfully apply the selected leakage management technologies based upon the pilot test results.

Water and Energy Efficient Showers Project Report (2007)

This report summarises the findings of an interdisciplinary study, which examined the factors influencing water use of domestic showering. Sponsored by United Utilities, it analysed the physical performance of 20 showerheads or flow restrictors through laboratory work, customer experiences associated with installations of water-saving devices in 18 homes, and water-related energy use through a comparison of shower and bath tube performance. The findings were used to identify and reinforce potential strategies to encourage efficient use of water and energy of showers in homes.

Water efficiency in the south east of England retrofitting existing homes (2007)

This study commissioned by the Environment Agency explores effective ways of increasing water efficiency in existing homes in South East England, building on findings of an earlier study. Following a pre-selection process, five demand management measures were analysed in-depth. Results indicate that average incremental social costs of retrofitting water efficiency measures compare favourably with the costs of traditional resource development schemes. The highest water savings would spring from a combination of different measures. The study also highlights that water savings increase significantly with only a small increase in cost if full subsidies and free installation are provided as part of the ‘package’.

South West Water Explicata WET Report 1 (2007)

This report by South West Water analyses a water efficiency trial for households. The study comprised ‘Control’ and ‘Sample’ households, 109 and 430 respectively, which were offered a variety of water-saving devices for installation. The analyses prior and after device installation indicate percentage water use reductions of approximately 10% per household, which declined to 6% after seven months following the installation. The water- saving device percentage reduction was greater the larger the number of devices installed in the household.

ESW Water Saving Toolkit (2007)

The purpose of this report is to summarise the findings of a customer engagement trial in Chelmford, Essex, which is part of Essex and Suffolk Water’s long-term water efficiency programme. 5,000 customers were mailed an application pack in 2006-2007, which included 19 water-saving products and services. Out of 5,378 customers contacted, 1,073 households completed the audit and were fitted with water-saving products and services. Based on information from meters and data loggers, the project resulted in average savings of 13.85 litre/property/day. This equates to a total saving of 0.015 Ml/day for the project study area.

Chelmsford ecoBETA Retrofit Project (2007)

This report summarises findings from a multi-measure water efficiency trial conducted as part of Essex and Suffolk Water’s long-term water efficiency programme. Customers in Chelmsford were fitted toilet dual flush devices and received a home water audit pack to improve water-saving practices. 18.7 % of the 4,866 customers eventually took part and 1,012 devices were installed in 555 properties. 187 customers completed and returned their home water audit form. Based on information from meters and data loggers, properties saved on average 31.38 litre/property/day. This equates to a total saving of 0.017 Ml/year for the project study area.

Garden Watering Restrictions_A Review of Hosepipe Ban Legislation (2006)

This report compiled by Waterwise seeks to clarify the aims of introducing a hosepipe ban, and suggests amendments to the legislation that would make restrictions relevant to today’s society and so be more effective in achieving the aims of a ban. The review briefly discusses the current water situation in the UK, looming changes to water supply, and factors that have led eight water companies imposing hosepipe bans by mid summer 2006. The shortcomings of the current legislation are assessed and finally amendments that could assist in creating a consistent approach to implementing restrictions during times of water shortages are proposed.
