Customer Experiences of Home Retrofit Products (2013)

This meta-analysis carried out by Waterwise investigates customer perceptions of professionally or self-installed water-efficient retrofit products in private homes. For the purpose of the study, 20 water efficiency projects with customer information available were selected. The main methods used in this study were a literature review and postal, telephone or online surveys. Water-efficient toilets, showers, taps, and garden devices were evaluated for performance aspects including product satisfaction, removal rates, aesthetics, and usability.

Embedding water efficiency into your EMS – Guidance

WRAP has produced this easy-to-use handbook to help food and drink companies integrate water management into an environmental management system (EMS). This handbook covers key areas that an EMS should address in relation to water management, including: environmental aspects and impacts; register of environmental legislation; objectives and targets; training; and procedures and work instructions. This guide will help environmental managers identify effective methods to embed good water management practices into their business, and ensure compliance with a certified EMS system. A correctly structured EMS will provide a mechanism to implement improvements in water management, and identify opportunities to improve water efficiency

Conservation Synergy: The Case for Integrating Water and Energy Efficiency Programs (2013)

This report articulates the reasons for, and the pathways by which, utilities can achieve a water-energy conservation synergy. Based on research and interviews with utility staff and experts, the report presents the procedural steps for implementing joint efficiency programmes. For different types of collaborative programmes such as rebates or audits case studies are provided. The study revealed that once initial logistics are worked out, it is easy to implement joint programmes. It also points out challenges, such differences in the operations of water, electricity, and gas utilities, as well as the lack of interest or ability by utilities to implement efficiency programmes.

Melbourne Residential Water Use Studies (2013)

This document is a summary of the results of two major studies in residential water use undertaken by water retailers within metropolitan Melbourne. The first is a sampling survey of water using appliance stock and usage pattern in 2012. The second consists of the measurement of the flow rates of individual end uses to a high resolution for a sample of customers in 2010 and 2012. The appliance survey relied primarily on self-reports for usage behaviours from large, statistically valid samples. The end use measurement study monitored actual flow rates, timings and frequencies of appliance usage amongst a small sample of customers.

Patterns of Water (2013)

This report contains the findings of survey research on the patterns of water using practices in households across the South and South East of England. Following a ‘practice based’ approach to water demand, this research takes practices as the unit of analysis when exploring water use – rather than attitudes, behaviours or simply ‘litres used’ – and highlights how this changed unit of analysis allows for a deeper understanding of the routines and habits of everyday life that lead to domestic water consumption – washing and personal hygiene, doing the laundry, gardening, cooking etc. The main results of the research are presented for household water infrastructure and technologies, for each of the separate water using practices, and for how the practices overall interrelate with one another. The final section then discusses the key implications of the work for contributing to designing interventions and to techniques for forecasting future water demand, pointing the way to future research and applications.

Understanding Household Water Behaviours and Testing Water Efficiency Messages (2013)

This summary sets out key findings from research undertaken by Icaro Consulting and Ipsos MORI on behalf of Defra. Via interviews and surveys this research gives insights in to household behaviours in relation to water use and the key motivations and test messages aimed at encouraging water efficient behaviours. the research highlights the potential role for a new suite of messages that target, variously, perceived norms, behaviours and specific household activities and routines.

Energy Efficiency in Water and Wastewater Facilities (2013)

This guide developed by the US Environment Protection Agency describes how water and wastewater facilities can lead by example and achieve multiple benefits by improving the energy efficiency of their new, existing, and renovated buildings and their day-to-day operations. It is designed to be used by facility managers, energy and environment staff, local government officials, and mayors and city councils. Readers learn about options to improve the energy efficiency of water and wastewater facilities and understand the steps and considerations involved in developing and implementing these energy efficiency improvements, as well as an awareness of expected investment and funding opportunities.

At Home With Water (2013)

At Home with Water, a study conducted by the Energy Saving Trust, analysed real-life water use in homes, and developed consumer-led water efficiency solutions. As part of its first phase, this report provides an analysis of self-reported water use information generated online through the Energy Calculator by more than British 86,000 households. The study revealed, among others, that individuals use 142 and households 349 litres of water per day. The average annual metered water bill amounted to £427. Hot water use contributes £228 to the average annual combined energy bill and produces 875 kg of CO2 per household per year.

Creating Water Sensitive Place: Scoping the Potential for Water Sensitive Urban Design in the UK (2013)

This scoping study together with the “Ideas Booklet” Water Sensitive Urban Design (WSUD) in the UK – ideas for built environment practitioners (C723) provides details of the drivers, benefits and vision of WSUD in the UK. It is based on findings from a collaborative project that included extensive consultation and a literature review to understand the role of WSUD in the UK.

Statistical Analysis of Seven Water Efficiency Studies using Control Groups and Weather Influences (2013)

This project by Essex & Suffolk Water was concerned with analysing and reporting the extent to which external factors influence demand during periods when water efficiency studies are undertaken. Seven studies were included in the analysis, both domestic and commercial retrofit schemes. Measured water consumption data were used to calculate the mean pre and post intervention consumption per day at each property. The difference between the pre and post consumption was calculated for each property.
