Virtual Water: the conceptual transformation of public and private sector water policy and metrics

Summary of the impact

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.

Dissolved air flotation

Summary of the impact

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.

Influencing international health policy to reduce acute waterborne diarrhoeal disease

Summary of the impact

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.

From source to tap: management of natural organic matter during drinking water production

Summary of the impact

New characterisation tools for natural organic matter (NOM) in drinking water are now used as standard practice within water companies such as Severn Trent Water, United Utilities and Yorkshire Water. The tools inform decisions, and help develop strategic plans on catchment management, source selection, treatment optimisation, and disinfection practice. Water companies experienced difficulties in treating high levels of NOM. Cranfield created a novel characterisation toolkit to measure NOM for its electrical charge and hydrophobicity. Also, new techniques for measuring aggregate properties and emerging disinfection by-products have provided a comprehensive analysis. Two novel treatment technologies are currently marketed. These technologies have raised international interest, resulting in industrial development in Australia.

Influencing international policy on improving access to water and sanitation services in the developing world

Summary of the impact

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.

Improved access to urban water services for over a million people in Uganda and other developing countries

Summary of the impact

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.
