② 水道需要 水道需要は、人口動態やライフスタイル、気象条件や社会経済状況など、様々な要因により変動する。
これまでは、経済成長や人口増加など、明らかに水道需要の増加が見込まれる時代もあったが、社会経済動向の不透明な状況、気候変動の進行、自然災害など、これまでに経験のない事象が水道需要に影響を及ぼすおそれがあり、今後の水道需要がどのように変化していくか、これまで以上に不確実性が増している。
しかし、水道需要は、施設整備の規模を定める重要な要素の一つであり、水道施設が 50 年から 100 年にわたって使い続けるものであることを踏まえると、常に安定給水を確保できるよう、できるだけ長期にわたる水道需要を見据えることが求められる。
都では、一日平均使用水量は、現在と同程度の量で推移し平成 30 年代にピークを迎えること、さらに、これに少なくともこれまでに経験した実績を確実に踏まえ、配水量の変動や漏水等を考慮した一日最大配水量は、ピーク時におおむね 600 万㎥となる可能性がある、と見通した。

② Water Demand in TokyoWater demand fluctuates according to population movement, life-style, weather condition and social economic condition.Up till now, we had seen the period where the increase in water demand was obviously dictated by economic growth and population rise, however, amid uncertain social economic trend, weather changes, natural disasters and so on, there is a risk that it may affect water demand that has never been experienced in the past. And in future, how will water demand change remain less certain. Nonetheless, water demand is one of the important factors that determine the scale of facility to be provided, and if we take into consideration that water facility will continue to be used for the next 50 or even 100 years, in order to secure stable water supply, it is required to estimate long-term water demand. In Tokyo, it is estimated to be the same as current daily average water use, and it will peak in 10 years from 2018 to 2027. Further, taking into account at least the result that had been experienced so far and the fluctuation including leakage in water delivery, the maximum water delivery per day at its peak is estimated to be about 6 million m3.

④ 財政制度と今後の財政運営 東京都の水道事業は、地方公営企業として運営されており、公共性の確保と経済性の発揮を求められている。会計制度については、公営企業会計方式を採用している。
また、独立採算で運営しており、事業運営に必要な経費は水道料金収入により賄っている。一方、建設事業は、企業債のほか、国庫補助金、一般会計繰入金などを財源としている。
予算の議決、決算の認定、水道料金改定(条例改正)の議決などは、都議会の権限である。

④ Financial System and Future Financial ManagementThe Tokyo Waterworks are operated as a local public enterprise, which is required to ensure its public nature and maintain economic efficiency. The waterworks uses the public enterprises accounting system as its financial system.Additionally, the waterworks business is conducted on a self-supporting accounting system, and the expenses required are covered by the revenue from water charges. On another front, the construction projects are financed by enterprise loans as well as governmental subsidies and money transferred from general account.The Tokyo Metropolitan Assembly has the authority to make decisions on the budget, approve account settlement, and make revisions to water charges (amendment of the ordinances).

昭和 30 年代から昭和 50 年代の高度経済成長期及びそれに続く数箇年は、水道需要の急増に対応した施設拡張による固定費の増加や物価の急騰などから、おおむね3年ごとに料金改定を行ってきた。その後、昭和 60 年代からは、経済情勢の安定や内部努力の推進などを背景に、財政状況はほぼ順調に推移してきた。
しかし、施設整備コストの上昇、水源水質の悪化による浄水処理経費の増加などにより、平成5年度末には単年度収支のみならず、累積収支でも不足額が発生した。
このため、平成6年に、平成9年度までの4か年を計画期間とする財政計画を策定し、内部努力を行ってもなお不足する額については料金改定を行うなどして財政基盤の確立を図ってきた。その後も健全な財政運営に努め、内部努力を行うことにより、平成 17 年1月には料金水準の引下げを実施した。
昨今では、安全でおいしい水へのお客さまニーズが高まっていること、高度経済成長期に整備した施設の老朽化が進んでいることに加え、東日本大震災を契機として、想定される大規模地震への対応などの課題も生じている。こうしたなか、これらの課題へ的確に対応するため、平成28 年 2 月には、平成 32 年度までの5か年を計画期間とする「東京水道経営プラン 2016」を策定した。この計画では、経費縮減と収入確保に取り組むことで、現行の料金水準を維持しながら、計画の最終年度となる平成 32 年度末には累積資金収支を均衡させることとしている。
Outline of Tokyo Waterworks 東京都水道局の概要
During the high economic growth period and several years after the period from the 1960s to the first half of the 1980s, we raised the water charges almost every three years due to an increase in fixed expenses for facility expansion in response to a sharp increase in water demand and a sudden rise in commodity prices. Since the second half of the 1980s, our financial condition has been favorable due to stabilization of economic conditions and promotion of internal efforts.However, at the end of FY 1993, the one-year balance as well as the accumulated balance was in the red due to an increase in facilities improvement costs and the increase in water treatment costs from deterioration in the quality of water resources.For this reason, we tried to establish a firm financial base by preparing a four-year financial plan with the planned period from FY 1994 to 1997 in 1994 and by raising water charges to compensate for deficits after our best efforts at reducing costs. We reduced the charge level in January 2005 by executing sound financial management and making our best efforts after the plan.In addition to the increased needs of customers for potable better tasting water and issues related to the deterioration of facilities developed in the age of higher economic growth, recently arising issues include countermeasures to possible large scale earthquake disaster. To handle these problems we developed “Tokyo Waterworks Management Plan 2016” in February 2016.The period of this plan is FY2016-FY2020. In this plan, we will balance accumulated income and expenditures by the end of FY 2020 while maintaining the current charge level by reducing expenses and the securement of revenues.

⑥ 東京水道長期構想―STEP Ⅱ― 水道局では、「東京水道新世紀構想―STEP 21―」に続く、新たな施設整備長期構想として、平成 18 年 11 月、
「東京水道長期構想 STEP Ⅱ~世界に誇る安心水道~」を策定した。この構想は、東京水道が将来にわたって、都民生活と首都東京を支える水道であり続けることを基本的な目標とし、これからおおむね四半世紀の間に行っていく施策の方向を示した基本構想であり、今後の水道施設整備の指針となるものである。
本構想では、首都東京の現状を踏まえ、東京水道のあるべき姿として「都民生活を支える水道」と「首都東京の機能を支える水道」の二つを基本視点と位置付け、今後、東京水道が進むべき六つの方向性と施策の展開を示している。

⑥ �Tokyo�Waterworks�Principal�Vision―�STEP�II―In November 2006, the Bureau of Waterworks developed the “Tokyo Waterworks Principal Vision STEP II – Safe Waterworks, our pride to the world” as a new facilities improvement principal vision following the “Tokyo Waterworks New Century Vision – STEP 21.” This vision basically aims to make sure the Tokyo Waterworks supports citizen’s life and the capital Tokyo in the future and is the basic vision that shows the directions of the measures for the next quarter century. It is also the guideline for improvements in waterworks facilities in the future.With this vision, based on the current condition of the capital Tokyo, two basic viewpoints: “waterworks supporting citizen’s life” and “waterworks supporting the functions of the capital Tokyo” are set as the basic policies of the Tokyo Waterworks, and the six goals and measures to be advanced and carried out by the Tokyo Waterworks in the future are shown.
1 Waterworks to support an affluent life2 High level waterworks to supply water stably3 Sustainment of waterworks for next generation4 Waterworks with global environmental consideration5 User-friendly waterworks6 Leader in the waterworks field

⑦ 東京水道施設再構築基本構想 水道局では、昭和 30 年代から 40 年代までの高度経済成長期に集中的に整備した膨大な水道施設が間もなく一斉に更新時期を迎え、こうした施設を再構築していく必要があることから、「東京水道施設再構築基本構想」を平成 24年3月に策定した。
本構想は、「東京水道長期構想―STEP Ⅱ―」に掲げたものも含め、今後取り組むべき水道施設整備のうち、再構築に関わるハード面の整備について、50 年、100 年という長期的な観点からその方針を定めたものであり、再構築を通じて、水道施設に新たな「安全度」を備えることを目指すこととしている。
新たな「安全度」とは、気候変動や首都直下地震など、想定される将来のリスクに対し、個別の施設の対策を可能な限り強化するとともに、それらを緊密に連携させることによって、たとえ複数のリスクが同時に発生するなど、これまで経験したことのない危機に直面しても、水道システム全体で確実に対応できることである。
本構想では、これからの 100 年も安全・安心な水道水を安定的に供給し続け、時代に応じた社会的要請にも的確に対応していくことを目指し、3つの方向性に基づき、7つの目標を掲げ、目標の達成に向けて、具体的な施策を展開していく。
Outline of Tokyo Waterworks 東京都水道局の概要
⑦ Basic Concept for Renewal of Tokyo Waterworks FacilitiesAs an enormous number of waterworks facilities, which were developed intensively during the time of higher economic growth between mid-1950s and early 1970s, are all about to face the time of renewal and need to be re-constructed, the Bureau of Waterworks formulated the “Basic Concept for Renewal of Tokyo Waterworks Facilities” in March 2012.Among the waterworks facility development projects that should be implemented in the future including the ones set forth in the “Tokyo Waterworks Principal Vision STEP II,” this vision sets a policy, from the long-term perspective of over 50, 100 years, of the hard infrastructure development associated with the reconstruction, and aims to provide waterworks facilities with a new “level of safety”.The new “level of safety” enhances countermeasures for potential risks in the future at individual facilities as much as possible (e.g. Tokyo epicentered major earthquake and climate change), and lets them cooperate closely with each other so that the whole water supply system could deal with crises never experienced before such as coincidence of multiple risks.Aiming to continue to stably supply safe and secure tap water in the coming 100 years and to respond appropriately to societal demands in accordance with the changes in the times, this vision sets 7 targets based on 3 directions and carries out the specific policy measures to achieve those targets.

⑧ Master Plan for Construction of Tokyo Waterworks FacilitiesThe Bureau of Waterworks has shown to the public what Tokyo Waterworks should be by describing them in the “Tokyo Waterworks Principal Vision STEP II” and the “Basic Concept for Renewal of Tokyo Waterworks Facilities”.To embody ideas presented in those visions, the “Master Plan for Tokyo Water Supply Facility Development” was formulated in April 2014 (revised in February 2016) in order to: clarify the direction of medium-to-long-term facility development after summarizing current status of waterworks services in Tokyo; set the development target in 10 years and specific efforts to achieve the target; and reflect them in the future business plans.The period of the plan is 10 years from FY 2016 to FY 2025.The Master Plan clarifies the directions of three main policy measures, namely “ensuring stable water supply”, “promoting earthquake countermeasures” and “providing potable delicious water”, after summarizing the ideas of facility capacity, facility renewal and water demands, all of which will be the essential factors for the future facility development. Based on the directions of those three main policy measures, we will put 18 projects into concrete shape, as well as setting 21 indexes as targets, steadily promoting the facility development and making every possible effort to ensure stable water supply in the capital Tokyo over the future.

⑨ Tokyo Waterworks Innovation ProjectThis Project aims at cooperate with various actors, evolve the world’s leading Tokyo Waterworks system further and promote it in Japan and overseas with an eye towards the IWA World Water Congress & Exhibition 2018, Tokyo 2020 Olympic and Paralympic Games, and the future further ahead of them.
Tokyo Waterworks has implemented comprehensive initiatives extending to the process from water sources through water outlets, currently attains world leading level of low leakage rate and has a back-up function that enables water supply even at the time of disasters, and continues to supply potable delicious water through advanced water treatment. In this situation, it is necessary to have customers’ understanding of initiatives and measures taken by Tokyo Waterworks.
In order to gain sympathy and understanding of customers from the standpoint of “Tokyo Citizens First,” we will consider the IWA World Water Congress & Exhibition 2018 and the Tokyo 2020 Olympics and Paralympic Games, in which a large number of people gathered together from inside and outside of Japan, as a great opportunity to introduce the attractions of Tokyo Waterworks and will develop various measures to promote the strengths and attractions of Tokyo Waterworks.
The main measures are as below:• Measures to secure good water source by concluding
agreements with companies, organizations, and others and carrying out forest conservation activities such as thinning and branching
• Measures to remind the importance of waterworks by providing experiences on mock water outage, emergency water supply, and transportation of water supply bags
• Measures to offer technical supports not only to foreign utilities but also to domestic utilities with high leakage rates by accepting trainees and dispatching professional lecturers to reduce the leakage rate.
The proposed initiatives are reviewed constantly, are developed further and are reported publicly continuously at appropriate times.
