Evaluation Guide for Water Efficiency Initiatives (2013)

This Evaluation Guide for Water Efficiency Initiatives developed by Waterwise helps water efficiency practitioners understand what evaluation is, why it is important, key aspects to consider when planning an evaluation, some of the different evaluation tools available and when they are useful. Its target group are those responsible for planning and carrying out water efficiency projects and programmes of work. It has been developed as part of the Waterwise Evidence Base for Large-scale Water Efficiency, an on-going effort to assemble knowledge and experience to make the case for and improve water efficiency initiatives, and is based on a range of sources, including literature and relevant experts.

Evaluating Water Efficiency Retrofit Projects: An Example (2013)

This guide developed by Waterwise is a supplement to the Evaluation Guide for Water Efficiency Initiatives. The main Guide helps water efficiency practitioners understand what evaluation is, why it matters, key aspects to consider when planning an evaluation, and when to use different evaluation tools available. This supplement Guide demonstrates how the evaluation tools and techniques can be put to use in retrofit projects. An invented water efficiency retrofit project is introduced, and then the evaluation process described, from the aims and objectives set at the outset, through to the conclusions drawn as a result of the evaluation findings.

Evaluating Water Efficiency Education Activities in Schools: An Example (2013)

This guidance developed by Waterwise is a supplement to the Evaluation Guide for Water Efficiency Initiatives. The main Guide helps practitioners understand what evaluation is, why it matters, key aspects to consider when planning an evaluation, and when to use the different evaluation tools available. This supplement demonstrates how the evaluation tools and techniques can be put to use in educational projects. An invented water efficiency retrofit project is introduced, and then the evaluation process described, from the aims and objectives set at the outset, through to the conclusions drawn as a result of the evaluation findings.

Effectiveness of Piggybacking Initiatives (2013)

This review carried out by Waterwise examines the effectiveness of water efficiency piggybacking initiatives and develops recommendations for enhancing their future uptake. Drawing on project reports of companies and interviews, the analysis considers achievements in terms of homes visited, devices installed and water saved. The study shows that where a piggybacking initiative is successful, it can provide extremely cost-efficient water savings for the water company while reaching higher numbers of households than regular water efficiency retrofit programmes. Challenges identified include lower installation rates than expected, lack of direct control over delivery and difficulty to measure water savings.

Delivering Multiple Benefits from Mainstreaming Water Efficiency

This work by Waterwise outlines recommendations for policymakers and regulators to step up incentives for, policy and regulatory outcomes, as well as benefits from larger-scale water efficiency across the UK. These emerged from the process of developing the Water Efficiency Evidence Base, as well as from water efficiency activity within the regulatory framework. Examples include identification of the links between water and energy and the cost-effectiveness of working in partnership to deliver water efficiency.

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.
