Response to the National Infrastructure Commission – New Technology Study Second Call for Evidence (August 2017)

Water efficiency is a key contributor to resilience, and water companies are currently carrying out large-scale retrofitting and customer engagement programmes. Ofwat and Defra are keen to see greater ambition on water demand management. The Waterwise Water Efficiency Strategy for the UK sets out a range of actions to improve water efficiency in new developments. Waterwise support a national and compulsory rollout of smart metering to provide benefits for customer engagement and water efficiency. We have set out barriers to new technologies as well as a range of new technologies identified by Waterwise and in research internationally.

Water Efficiency and Drought Communications (2013)

Waterwise collected information on drought communication and activities from the seven companies who imposed customer restrictions (‘hosepipe bans’) in the South and East of England during last year’s drought. Working with Water UK and WWF, Waterwise analysed these activities to assess, whether they met their statutory drought duties and whether they had an impact on customer attitudes.

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.

Response to Ofwat’s Consultation on Minor Revisions to Water Efficiency Target Methodology (2012)

Waterwise is extremely supportive of Ofwat’s plans to put in place a framework to incentivise and reward water companies for work to help develop robust evidence on the effectiveness of water efficiency measures. This framework would allow companies’ contributions to a collaborative evidence base fund to count against a small proportion of their volumetric base targets. We report here discussions on governance of the fund agreed by the companies and the key players in summer 2011. We are cautious about removal of the cap on soft measures.

Investigating the Impact of Water Efficiency Educational Programmes in Schools (2012)

This report developed by Waterwise assembles information about water efficiency educational programmes and measures used to evaluate their impact. A literature review was undertaken and information was requested directly from water companies and other organisations. The study reveals that many different educational programmes are taking place in the UK while their effectiveness remains under-investigated. Knowledge gaps exist regarding what educational activities are most effective, whether behaviour change is long-term, as well what type of evidence is collected or incentives offered. It is recommended to evaluate more educational programmes with consistent approaches and facilitated by professional guidance to produce more reliable knowledge.

Save Water Swindon Phase 1 Evaluation (2012)

This report evaluates phase one of Save Water Swindon (2010-2011) and identifies achievements and faced challenges. The project, the first to take a “whole-town” approach, attempted to raise awareness about the importance of saving water and deliver large-scale water savings. During year one, just under 900 home makeovers were completed, and 900 self-install kits were given out to residents. In total, nearly 6000 water saving devices were distributed and installed, resulting in assumed water savings of nearly 50,000 litres/day by the project. Average savings between makeovers and self-install kits differed substantially, 39 compared to 16 litres/property/day.

Resources Available to Business to Quantify and Reduce the Water Impacts of their Water Use (2012)

This study was commissioned by Defra to inform businesses about resources to assess and understand the impacts of their water use. 34 resources such as risk assessments were identified through a literature review and expert comment, out of which ten were further investigated. The study is considered to provide a good insight into different available resources and help businesses to ask the right questions to identify the most appropriate resources for their purposes. Engaging more business users, stronger cooperation between stakeholders, and the development of a decision-support framework for selecting options were viewed as important for driving future water efficiency efforts by businesses.
