Thousands of homes in west and south-west London were left with no or low pressure water on Wednesday after a power supply issue at a Thames Water plant.
Schools were forced to shut with Thames Water saying the issue at its Ashford and Hampton water treatment works on Wednesday morning impacted more than 50 postcodes.
Residents in Putney, Wembley, Twickenham, Richmond, Southfields, Hampton, Uxbridge and White City were among those affected while Hounslow Council reported no or low water in the parts of the borough.
Several schools notified parents of their closure while others said they were “monitoring the situation” and would update parents throughout the day.
Thames Water later said the power supply has returned and “supplies should be starting to return across the area”.
The following postcodes were hit by the problems: SW4, SW8, SW9, SW13, SW14, SW15, SW18, SW19, TW1, TW2, TW3, TW4, TW5, TW7, TW8, TW9, TW10, TW11, TW12, TW13, TW14, TW17, W1H, W1H, W1M, W1N, W2, W3, W4, W6, W7, W10, W12, W13, W14.
