chapter 1 – future water 1 our vision for water policy and management is one where by 2030 at the latest we have • improved the quality of our water environment and the ecology which it supports and continued to provide high levels of drinking water quality from our taps • sustainably managed risks from flooding and coastal erosion with greater understanding and more effective management of surface water • ensured a sustainable use of water resources and implemented fair affordable and costreflective water charges • cut greenhouse gas emissions and • embedded continuous adaptation to climate change and other pressures across the water industry and water users 2 water is essential for life it is vital for our health and wellbeing drinking and sanitation and for agriculture industry and transportation beyond these uses water brings countless other benefits to society we use it to swim in sail on water our gardens and take pleasure in the plants and

chapter 3 – water supply drinking water quality 22 drinking water must be wholesome at the point of supply that is from consumers’ taps wholesomeness is defined in legislation by reference to drinking water quality standards which relate primarily to human health but also ensure that water is acceptable for water treatment processes as well as for consumers 23 water companies have a duty to test water samples for certain substances and organisms the drinking water inspectorate dwi set up in 1990 as the independent regulator of drinking water quality checks the accuracy of these tests and publishes summaries of results enforcement action by dwi has ensured that nearly all of our water supplies now meet all of the drinking water standards in 2006 99.96 of tests met the required standard 24   it is essential that good quality drinking water and the investment by companies necessary to achieve it is maintained into the future to facilitate this the government

future water the government’s water strategy for england pollution from sewage 16 nutrient pollution from sewage effluent is mainly tackled by the water industry at sewage treatment works but this is not an area we can ignore we have recently announced 24 more nutrient sensitive areas where additional action will be taken at sewage treatment works to tackle nutrient pollution problems there are also ways to address problems by natural means for example water can be passed through reed beds to reduce sediment and help absorb run-off retaining wetland habitats such as peat bogs also helps prevent flooding and soil erosion and assists in building up groundwater supplies 17 the thames tideway scheme consisting of large scale infrastructure improvements to london’s combined sewer system and treatment works will address pollution from sewage which affects the tidal river thames and the river lee it is expected to be completed by 2020 and will make significant improvements to

future water the government’s water strategy for england box slowing water down – infiltration and soakaways infiltration is an important measure in managing surface water in a more sustainable way by mimicking natural processes however implementation requires careful consideration and it is not applicable in all situations depending on soil and ground conditions in general infiltration techniques are more appropriately located close to the source of run-off before flows have concentrated into large volumes there are a number of infiltration techniques including • soakaways these may take the form of stone filled trenches or porous chambers they can be used for draining surface water from roofs or run-off from roads and other surfaces building regulations set out in detail where and how soakaways can be used • porous surfacing this can consist of concrete blocks porous tarmac or loose gravel all are applicable to situations within private properties blocks

chapter 7 – greenhouse gas emissions 4 but the use of hot water in our homes for such things as personal and household washing cooking and cleaning but excluding that for space heating contributes roughly another 35 million tonnes of greenhouses gases co2e per year this is seven times as much as that emitted by the industry itself and amounts to over 5 of total uk greenhouse gas emissions 5 as mentioned in chapter 2 water efficiency measures are a real win-win solution they reduce water use as well as energy use and therefore greenhouse gas emissions water efficiency measures that focus on reducing hot water use would result in much larger greenhouse gas reductions in addition there would be savings on customers’ water and energy bills this is one reason why water efficiency and water saving work should be extended beyond areas of water stress government is taking action to help people understand this important link between hot water usage and greenhouse gas emissions as

chapter 8 – charging for water box south west affordability pilot study the south west affordability pilot study was designed to help those on low incomes with their water bills the measures tested were 1 benefit entitlement checks 2 switching to a meter 3 eligibility for the vulnerable groups tariff and 4 water audits and water efficiency devices the pilot finished in october 2007 after over two years of experimental measures and analysis of their costs and benefits analysis showed most of the measures to be cost beneficial and that the combination of measures had a positive impact for a lot of households particularly those switching to meters the measures used in the pilot have already been followed up by south west water under the name watercare we encourage other water companies to consider providing a similar service to their customers more information on the pilot is available at www.defra.gov.uk/environment/water/industry/affordability/index.htm social and environmental
