<ul><li><p>Shape your water future.</p><p>Draft water resources management plan 2019</p><p>Overview</p></li><li><p>32</p><p>We take water from rivers and under the ground, treat it and distribute it to homes and businesses across our supply area through a network of underground pipes. Every day we supply our customers with more than 2,600 million litres of water - enough to fill 1,000 Olympic sized swimming pools.</p><p>Introduction</p><p>Water is essential for everything we do - from having a drink, to washing our clothes, and flushing the loo. Its also essential for a healthy environment and a prosperous economy. Its our job to provide a reliable supply of safe drinking water to around 10 million household customers and 215,000 businesses in London and across the Thames Valley.</p><p>Many people think there is plenty of water in the UK, but the South East of England is one of its driest regions and London gets less rain than Rome, Dallas and even Sydney. Our water supplies are being stretched further and further as the number of people living in our area increases. We have to plan ahead, because the choices we make today will shape the water supply we can provide in the future. </p><p>This document is an overview of our draft Water Resources Management Plan 2019, referred to in this document as our water plan. It sets out how we plan to provide a secure and sustainable supply of water for our customers over the next 80 years from 2020 </p><p>to 2100. We have to comply with legal requirements and have followed the governments guidelines in preparing our water plan.</p><p>We want to hear what you think, and are running a public consultation on our water plan, starting in February 2018 and closing on 29 April 2018. Your feedback will help us decide how to meet our customers needs in the future.</p><p>Were also developing our draft Business Plan, which focuses on the first five years (2020 to 2025) of the period covered in our water plan, and sets out what we are going to do for both our water and wastewater services. Were also seeking your views on this plan.</p><p>Your current water supply</p><p>This document is an overview of our water plan.This symbol signposts the relevant sections of the more detailed report if you want to read more.

This takes water from the Thames </p><p>estuary, removes the salt, and treats the water. It is an important reserve </p><p>but is a last resort as it is expensive and uses lots </p><p>of energy. </p><p>Section 1: Introduction and backgroundSection 2: Water resources programme 2015-2020</p><p>Water is stored in reservoirs to use when the flow in rivers is low, or of poor quality. Our </p><p>reservoirs hold about 100 days supply of water.</p><p>In London, about 80% of our water is taken </p><p>from the River Thames and the River Lee.</p><p>In the Thames Valley, around 70 % of our water is taken from </p><p>underground sources in the Cotswolds and the </p><p>Chiltern Hills.</p><p> Our area and the wider South East are classified by the Environment Agency as seriously water stressed.</p><p> The Thames river catchment is the most intensively used water resource system in England. Around 90 per cent of water that is abstracted is for public water supply. The remaining 10 per cent is for energy generation, agriculture and other uses. The Environment Agency regulates these abstractions.</p><p> About 38 per cent of our household customers have a water meter.</p><p> On average each of our customers uses 146 litres of water every day.</p><p> Around 25 per cent of the water we put into supply is lost through leaks from our water supply pipes and our customers pipes.</p><p>Key facts</p></li><li><p>54</p><p>Our water supplies are already under pressure, and this will increase in the future. The number of people living in our area is growing rapidly and they will all need water.</p><p>Population growth - London and the Thames Valley is already one of the most densely populated parts of the country, and the number of people living and working here is forecast to grow significantly. By 2045 we forecast that there will be around two million more people living in our area. Thats the equivalent of Birmingham and Glasgow moving in. And by 2100 we forecast that there could be more than 15 million people living in our area. </p><p>Climate change - Our climate is changing. Hotter, drier summers in the future will mean that there will be less rain when we need it most, and extreme weather events are likely to be more common.</p><p>Looking ahead</p><p>This shortfall will start in the next five years and is forecast to grow to around 360 million litres of water per day by 2045. Thats equivalent to the amount needed by over two million people. The shortfall is forecast to increase to 864 million litres of water per day by 2100, the end of our planning period.</p><p>The challenge is most severe in London, but we also forecast a significant shortfall in the Swindon and Oxfordshire region, and other parts of the Thames Valley.</p><p>2019</p><p>10.2mpeople</p><p>Forecast population growth:Thames Water supply area</p><p>2045</p><p>12.0mpeople</p><p>2030</p><p>11.0mpeople</p><p>2080</p><p>15.3mpeople</p><p>2100</p><p>15.4mpeople</p><p>We have used data from the Mayor of London and local authorities to develop our </p><p>forecasts of population growth. </p><p>Environment - Wildlife in wetlands and rivers relies on a healthy environment with plentiful water. We need to balance the water we take for our customers with what we leave in the environment. We will continue to reduce the amount of water we take from rivers in parts of our region where the environment is under pressure.</p><p> litresper day</p><p>e.g</p><p>or</p><p>without water for a day</p><p>x11million</p><p>x6million</p><p>864million</p><p>Supply demand shortfall:Thames Water supply area</p><p>DEMAND = Amount of water we need</p><p>By 2100 we forecast that there willbe a shortfall of:</p><p>SUPPLY = Amount of water available</p><p>2019</p><p>10.2mpeople</p><p>2045</p><p>12.0mpeople</p><p>2030</p><p>11.0mpeople</p><p>2080</p><p>15.3mpeople</p><p>2100</p><p>15.4mpeople</p><p>Taking all these factors into account, we predict there will be a shortfall between the amount of water available and the amount we need unless we take action. </p><p>Section 3: Current and future demand for water</p><p>Section 6: Baseline supply demand position</p><p>One mega litre equals one million </p><p>litres of water and is equivalent to the water used by about 7,000 </p><p>people each day.</p><p>At the same time, the amount of water that we can take from rivers and underground sources is reducing, due to changes in the climate and the need to protect the environment.</p><p>Section 4: Current and future water supply</p></li><li><p>76</p><p>There are also other factors which affect our water plan.</p><p>A regional perspective - The pressures of population growth and climate change are affecting the whole of the South East of England not just our area. In our water plan we have aimed to meet the growing water needs of the wider South East of England, taking into account opportunities to transfer water from across the region and beyond. By working together with other water companies across England and Wales were taking a coordinated approach to planning for the future and making sure all our plans offer customers the best possible value for money. Some of our neighbouring companies have asked us to provide water to them in the future, which their customers would pay for, and we have included their needs in our water plan.</p><p>7</p><p>The UK is often thought of as rainy, but we do have dry spells and droughts when the amount of water in the ground and rivers is low. In severe droughts we might need to put in place water restrictions. This would mean that water for everyday activities would be rationed and your water might be turned off for periods during the day. These restrictions could last for several weeks. As well as disrupting our customers lives, restrictions would also have a damaging effect on the natural environment, and could cost Londons economy alone up to 330 million every day. We know that there have been severe droughts in the past and these are likely to happen more often in the future. We need to plan ahead to protect our customers and the environment from their effects. Our customers have told us that they would like us to plan to provide a more reliable water supply to cope with the effects of a severe drought. This is also supported by the government.</p><p>The pressures on water supplies </p><p>are expected to become very serious in the future </p><p>and we need to act now to make sure there is a safe </p><p>and reliable supply of drinking water for our </p><p>customers.</p><p> Our proposed plan is designed to maintain all of our customers water supply, with no need for it to be rationed, during a severe drought (the kind that might happen once in every 200 years). We have some options about how quickly we achieve this:- Ensure that we can maintain all of our customers water </p><p>supply during a severe drought, by 2030- Delay the work so we can maintain all of our customers </p><p>water supply by 2035.- Speed up the work so we can maintain all of our customers </p><p>water supply by 2027, the earliest we can deliver suitable options.</p><p>Please give us any comments on this.</p><p>Section 4: Current and future water supply</p></li><li><p>8</p><p>We have worked closely with our customers to understand their views and preferences. We have asked them what we should consider in developing our water plan; whether and how often they are prepared to accept restrictions like hosepipe bans during a drought and where they think we should get the water from. We have listened to their feedback and used this information to develop our water plan. Heres a summary of what our customers have told us.</p><p>9</p><p>What our customers want</p><p>As well as listening to our customers, we have also listened to our regulators, who are responsible for making sure customers get good value for money, and protecting the environment. We have also spoken to lots of other interest groups. These include environment groups like RSPB and WWF, organisations representing businesses, such as the Chambers of Commerce, and many more. We have done this to make sure we understand their different interests, and have used their feedback to help prepare our water plan.</p><p>9</p><p>Appendix T: Customers priorities and preferences Appendix S: Stakeholder engagement</p><p>Weve engaged with over </p><p>18,000 customers in developing our future plans through research, day-to-day interactions and local community events.</p><p>Most customers do not want more frequent restrictions on their water use.Over 60% told us that this would affect their daily lives.</p><p>The bill is important in deciding future plans, but it is not the only factor. Customers support best value planning. Best Value</p><p>Once they understand the challenges, they want to know that we are planning for the future.</p><p>Most customers are unaware of the challenges for future water supply.</p><p>Communities that would be affected by future development would like to be engaged on plans.</p><p>Customers think that the current levels of leakage are too high and would like us to do more to fix leaks.</p><p>Alongside leakage reduction and helping our customers use water efficiently, customers also support the development of new water resources.</p><p>Over 70% of customers said they want help to reduce their water use.</p><p>In 2016 we visited over 60,000 homes and installed more than 200,000 water saving devices </p><p>helping our customers save water and </p><p>money.</p><p> Please give us your comments on our summary of our customers views.</p></li><li><p>1110</p><p>Options available to help man age future water supply</p><p>11</p><p>Demand management options Our first priority is to make sure that we make the best use of the water we already have. Well do this by: Continuing our work to reduce the amount of water lost through leaks from our pipes. This </p><p>year we did not meet our target to reduce leaks for the first time in 11 years but we have a detailed plan to reduce leakage to 646* million litres a day by 2020. We are investing in new technology to help find more leaks and employing additional people to repair them. In our water plan we have considered a number of options to continue to reduce leakage, and have set out how much more we can reduce leakage by, and how quickly we can do it.</p><p> Installing meters in our customers homes. Smart meters help us to understand where water goes, helping us to tackle leakage, they also help our customers understand how much water they use and how they can reduce it, saving both money and water. Since 2015 we have installed more than 145,000 smart meters in our customers homes and around 38 per cent of our household customers are metered. In our water plan we have considered how we will continue to roll out this programme.</p><p> Helping our customers use water efficiently. We are currently delivering the UKs largest ever water efficiency programme. This includes a wide number of activities and promotes the benefits of saving water at home and in the workplace. This year we visited more than 60,000 of our customers homes, provided specific advice, and installed more than 200,000 free water saving products. In our water plan we have considered how we can continue to develop our programme, looking at new and innovative approaches to help our customers to reduce their water use.</p><p>We looked at more than 200 options to help to fill the shortfall between the amount of water available and the amount we need. These include ways to make the most of the water supplies that we already have available, called demand management options, and new sources of water, called water supply options.</p><p>Water supply options We have looked at a large number of options to boost our water supplies, from traditional techniques to more innovative and unusual approaches. They include turning seawater into drinking water (desalination), reusing treated wastewater from sewage treatment works, and building a large storage reservoir. We have also talked to other water companies to see if they have spare water that we could buy, including moving water from North West England, and Wales, to the South East of England.
