Research conducted at Aston University on the performance of the water and sewerage industry influenced water industry regulation and the shaping of the Water Bill 2013-14, which had its first reading in the House of Commons on 27 June 2013. Specifically, the research: changed understanding and awareness in the debate preceding the Water Bill by highlighting potential costs associated with vertically separating water companies (Impact 1); influenced the Water Bill's prohibition of mandatory company separation, while also providing evidence that facilitated the Bill's provisions to establish a Great Britain wide retail market for non-household water customers (Impact 2); and changed policy makers' awareness of panel cost and productivity assessment methods, thereby influencing consideration of their future application to regulatory cost assessment (Impact 3) .
The virtual water concept is used to identify and quantify water use which is hidden, or embedded within the production and supply of food and other commodities. Its primary application has been to demonstrate that the majority of water consumed globally is used within the production and trade of food. Introduced and developed by Allan, virtual water research has transformed public and private sector water policy and its metrics in the UK and internationally. Instantiated through conceptual work published in 1993 and 1994 and developed through empirical studies thereafter, virtual water was widely adopted by 2000. The idea is now accepted as an essential element in the framing of policy on water security and its economic systems. Virtual water has been increasingly deployed by advisers to governments, corporations and NGOs, below we provide evidence from the U.S. State department, Coca Cola, WWF and the World Economic Forum, this is by no means a complete list. In 2011 the UK House of Lords and UK government's official response urged the EU Commission to incorporate virtual water in EU Policy. In recognition of the global conceptual impact of virtual water, Tony Allan was awarded the Stockholm Water Prize, 2008. In 2013, in recognition of impact made in preceding years through his virtual water concept and research Allan was also awarded the Foundation Prince Albert II de Monaco Water Award and the International Environmentalist Award of the Florence-based Fondazione Parchi Monumentali Bardini e Peyron.
This case study describes a series of research projects undertaken by Professor Hulya Dagdeviren from 2004 to 2012 on issues related to the commercialisation and privatisation of water and sanitation services, which involved changes in the control and management of former public utilities. In particular, it focuses on the findings and impacts of the studies in relation to the access and affordability of these services for poor households in the developing countries. The results of these studies influenced the policy directions of international institutions, especially the UN agencies, which play an important role in funding projects and policy advocacy that ultimately shape the national policies of the developing countries.
The impact is a change in the behaviour of water companies in investment planning processes to meet with 5-yearly Periodic Reviews with the industry regulator (Ofwat), and on the requirements by Ofwat for water companies to adopt a cost-benefit approach that takes account of water customer preferences. It is based on findings from a research programme concerned with economic approaches to utility regulation theories and practice. Policies, processes and practices of water companies and Ofwat, at a national level, have been affected, with respect to the 2009 and 2014 Periodic Reviews. The impacts are primarily economic, commercial and organizational, and environmental. The beneficiaries are water companies, their regulators, and customers.
University of Manchester research during 2005-2012 into water sector technological innovation provided an evidence base that changed UK and European policy and practice. The research led to an extended remit for an independent review of UK water sector competition to include also innovation; underpinned sections on innovation in new UK water policy; inspired incentive reforms by the economic regulator, Ofwat and informed strategy for two high-level European innovation/technology platforms. Lead researcher Thomas advised key stakeholders at House of Commons All Party Parliamentary Water Group sessions, at an independent review, via keynotes and opinion pieces for industry roundtables, conferences, trade journals, the media, and on an Ofwat advisory panel.
Research at Cranfield has underpinned national policies for managing and allocating the UK's agricultural water resources over the past 20 years. It has supported major reforms in water policy, abstraction legislation and drought management. It has done this by modelling spatial and temporal variations in demand for irrigation, linking this to the financial impacts of water stress on crop yield and quality, projecting future demand, and assessing climate change impacts and potential adaptations. It has also significantly impacted the agri-food sector, helping agribusinesses assess the viability of irrigation and reservoir investment, encouraging collaboration, and reducing risks in the food supply chain.
Over a million urban dwellers in several developing countries are accessing water services as a result of research undertaken at Loughborough University. National Water and Sewerage Corporation (NWSC), Uganda's main urban water utility, applied the research findings to improve service quality, and extend piped water supply to the previously un-served. During 2008-2011, over 500,000 additional urban residents accessed piped water supply of improved bacteriological and physico-chemical quality — resulting in significant enhancement of health and quality of life (particularly of children). Furthermore, the research benefits were transferred to other countries, through the work of NWSC's External Services Department, extending the reach to other countries including Kenya, Tanzania, India and Zambia.
This case study focuses on the Israeli-Palestinian water conflict within the context of the Oslo peace process. It documents four areas of impact, the underpinning research and associated engagement and dissemination activity having: (1) [text removed for publication] (2) significantly enhanced public and policy understanding of, and debate on, the Israeli-Palestinian water conflict, within Israel, the Palestinian territories and internationally; (3) [text removed for publication] and (4) contributed to the emergence of influential critiques of international policy on water `cooperation'.
Diarrhoeal disease is the world's second most common cause of death in children under five years old, killing 760,000 children each year according to the World Health Organisation (WHO). Microbial contamination of drinking water is one of the most important causes. In England and Wales acute diarrhoeal disease is estimated to cost the country £1.5 billion annually. UEA epidemiologists have shown the important role of water supply systems in spreading diarrhoeal disease in developed and developing countries; led WHO research projects on small scale drinking water systems; and influenced WHO policy on small scale drinking water systems in developed and developing countries. Methodological research on epidemiological methods for monitoring and regulating bathing water quality has led to changes in WHO guidance on bathing water quality standards and influenced US Environmental Protection Agency criteria. Hunter's participation in international expert panels facilitated the impact of this research on policy.
By modelling the formation of micro-bubbles and the flows induced by them, researchers at the University of Cambridge Department of Applied Mathematics and Theoretical Physics developed a new, low-cost nozzle design that could be retrofitted to existing Dissolved Air Flotation (DAF) systems. This new design dramatically improved the performance of DAF systems, used by the water industry for the production of drinking water. Specifically, this research has enabled a substantial increase in throughput and effectiveness of the flotation process, whilst simultaneously providing a dramatic decrease in the energy requirement.
