夏の水道基本料を無償化　４カ月分、物価高と暑さ対策で―東京都

　東京都の小池百合子知事は２０日、都庁で報道陣の取材に応じ、物価高対策として都内全ての一般家庭を対象に、今夏の水道基本料金を４カ月分無償化すると発表した。猛暑が予想される夏に光熱水費の負担を軽減することで、自宅でのエアコン使用を促す熱中症予防の目的もある。
　６～９月分または７～１０月分を無償化。６月開会予定の都議会定例会に必要な経費３６８億円を盛り込んだ補正予算案を提出する。小池知事は「この夏に限った臨時的な措置として無償にする。都民が安心して暮らせる環境を整えたい」と述べた。
　都内の水道料金は、固定費に当たる基本料金と、使用量に応じて変動する従量料金がある。基本料金は水道管の口径の大きさによって異なり、一般家庭向けは１３ミリが月８６０円、２０ミリが月１１７０円、２５ミリが月１４６０円となっている。都内の世帯数は１月１日時点で約７６８万世帯。今回の対策では、標準家庭で１世帯当たり計５０００円程度の負担軽減になるという。従量料金は減免しない。（2025/05/20-18:11）

The Tokyo metropolitan government is considering waiving basic water supply charges for all general households in the Japanese capital during this summer to cushion the impact of inflation, informed sources said Tuesday.
   The metropolitan government hopes to encourage the use of air conditioners to prevent heatstroke by reducing residents' spending on utility bills during the season, in which intense heat is forecast. It plans to implement the program for several months.
   The metropolitan government will submit a supplementary budget bill that features necessary costs for the program to a regular session of its assembly to be convened in June after hammering out the details.
   Water bills in Tokyo comprise fixed basic fees and variable charges depending on usage amount. Fixed basic fees are charged based on the size of water pipes. For general households, the monthly basic fee for a 13-millimeter pipe is 860 yen, that for a 20-millimeter pipe 1,170 yen and that for a 25-millimeter pipe 1,460 yen. This summer's program will not waive variable water usage fees.
   For some areas in Tokyo where the metropolitan government's Bureau of Waterworks does not supply tap water, a similar scheme to waive basic water supply fees is being considered, the sources said.
