Planning Effective Water Efficiency Initiatives (2012)

This short guide produced by Waterwise and WWF-UK identifies eight key elements to consider when planning a home visit programme for water-saving devices, including how to formulate realistic expectations for partnerships or selecting the right products. It draws on the lessons learnt from two large-scale water efficiency retrofit initiatives (Save Water Swindon and Tap into Savings), as well as other projects included within the Water Efficiency Evidence Base.

Improving Uptake in Home Visit Retrofit Programmes (2012)

This report by Waterwise sets out to better understand the factors influencing the uptake of home visit and home retrofit projects and reviews recruitment methods that were deployed successfully and unsuccessfully in previous programmes. Evidence was collected through a literature review focusing on information available for the UK and phone interviews with people closely involved in the recruitment process. The research elicited crucial insights about common methods including letters, phone calls, and door-knocking, when, where and how to use them, but also identified knowledge gaps for future research.

How to Manage Change and Improve Water Efficiency

WRAP has produced this easy-to-use handbook to help food and drink companies establish changes that improve their water efficiency. This handbook covers two key areas that will help facilitate behaviour changes within your business: understanding and challenging behavioural inertia; and identifying the ingredients for success: – drivers for change: senior management commitment is essential; – clear and shared vision: staff at all levels should be on board; – capacity for change: providing the resources, time and budget to deliver your desired outcome; and – prioritise action: using the ’plan-do-check-review’ approach and ensuring that you keep communication routes open.

An evaluation of the Plug In water saving project (2012)

This report investigates the Plug In Water Saving Project, which aimed at installing water saving measures in social housing in the East and West Midlands, and to promote behavioural change among residents. Set up by the Environment Agency and several partners, the project engaged seven social housing providers and their residents in water-saving activities on a larger scale than previous projects. More than three and a half thousand measures have been installed in approximately three and a half thousand homes up between 2011 and 2012.

Lydd Retrofit Trial Report (DRAFT) (2012)

This report analyses a water-efficiency retrofit trial from 2009, which Veolia Water South East carried out as part of its metering trial activities and compulsory metering programme in the town of Lydd. Its main goal was to understand customer’s perceptions around various aspects of implementing retrofit programmes through four focus groups. 1,450 households were invited by phone call, of which participated 250 in the trial. 43 % of the 163 successfully interviewed post-trial indicated having had a positive experience with the water-saving devices. The majority believed water savings were low and that they reduced their bill “a little”, £4.26 on average.

Water Sector Report Climate Change Risk Assessment (2012)

The purpose of the first Climate Change Risk Assessment (CCRA) was to assess the key risks and opportunities facing the UK from climate change to the year 2100. The CCRA is required by the Climate Change Act 2008 and will be completed every five years. This Water Sector Report is one of 11 Sector Reports and is a key step in the process of developing the evidence base for the CCRA. The analysis described in this report covers three themes: pressures on water availability, water quality, and the deterioration of water company assets.

United Utilities Home Audit Project

This report brings together findings from a trial carried out by United Utilities in 2006-2007 that investigated the effectiveness of water-efficient devices. 4,642 domestic properties in Warrington were sent an invitation. 393 took part in the audit and received a ‘water savers pack’, which included a basic shower timer and information on saving water. Further devices were installed where appropriate including water efficient showerheads, dual flush retrofit and save-a-flush cistern displacement devices. 67 % of 211 measured households were able to save water, on average 20.6 litres per property per day, which represents a reduction in water use of 6.8%.
