this under storm conditions in order to prevent flooding. Incorrectly connected drains add to the pollution of rivers and canals. Rainwater runoff in an increasingly paved London carries yet more pollutants – so called ‘diffuse’ pollution because it has no singe source – into ponds, lakes and streams. All these have serious consequences for health, biodiversity, tourism and the overall quality of life. • To reduce the threat to people and their property, businesses and essential infrastructure from sewer, groundwater and surface water flooding and to mitigate its effects. As the climate changes, London needs to maintain and improve its resilience against river and tidal flooding – to be covered more fully in the Mayor’s Climate Change Adaptation Strategy. However, all too often other sources of flooding – from surface water (as experienced in the summer of 2007), groundwater and sewers – are overlooked. These problems are also likely to get worse as a result of climate change. Proper attention being given to the nature of the site in terms of site layout and building design, and properly integrated, designed and managed drainage and sewage systems are all essential to alleviating these types of flooding. Principles • Delivering practical changes locally. There are many ways in which London can use the water that it already has more effectively. We need to reduce our water consumption before looking beyond London for new resources. • Maintaining London’s infrastructure for future generations. London now has to bear the cost of past failures to maintain and renew its infrastructure. We have to bear these cost rather than pass an even larger burden on to future generations • Promoting consumer awareness and help consumers to avoid unnecessary consumption. There are many opportunities, and a need, to educate Londoners about where their water comes from, how we can use the water that we already have more effectively and efficiently, and how we can all benefit from doing so. • Working together. Organisations should work together to avoid duplication, minimise conflicts and achieve better results. Implementation and monitoring 1.21 The majority of the actions proposed or referred to in this strategy are being or will be implemented by organisations other than the Mayor of London. The role of the Mayor is to set out his vision of how Londoners will best be served, and to work with the organisations responsible for providing or regulating the services to achieve the optimum outcome. 1.22 This strategy does not propose any additional monitoring arrangements. The returns submitted by every water company to Ofwat in June each year, known as the June Returns, provide a mass of data 23
24 The Mayor’s draft water strategy that is then made available on the Ofwat website. This, for example, is the source of the information provided in Table 2.7 Water supply statistics for London. The environmental performance of the water companies is monitored by the Environment Agency that publishes a wide range of information on, for example, water resources and river pollution incidents. Last, but not least, the Mayor is required to publish a State of the Environment Report for London every four years. Next steps The publication of this draft starts a three month period of consultation with the public and other stakeholders, during which the Mayor would like to receive your views about the issues raised in the strategy. Consultation ends on 27 November 2009. Please send your comments by email to water@london.gov.uk or by post to : Draft London Water Strategy Post point 19 City Hall The Queen’s Walk London SE1 2AA
