Chiba Prefecture began distributing bottled water at evacuation hubs Friday as roughly 2,700 households remained without tap service after Typhoon Dujuan knocked out pumping stations and broke mains beneath flooded streets.
Health risks beyond thirst
Officials warned that without pressure, contaminated groundwater can seep into cracked pipes. Residents are told to boil water if any flow returns brown, but many blocks have zero flow, making bottled supplies the only safe option for infants and elderly residents on diuretics.
Logistics on damaged roads
Trucks carrying water cases are using the same mud-choked routes TEPCO repair crews need, forcing prefectural planners to sequence convoys at night. Shelters report enough stock for three days, with resupply dependent on whether county roads reopen before the Sports Day holiday.
Coordination with power restoration
Water plants need electricity before taps run clear. Health teams said they will publish a daily list of hubs offering showers once generators arrive, but for now hygiene depends on wet wipes and portable toilets. Nurses asked donors to stop sending perishable food without cold storage.
Medical support
Prefectural nurses set up dialysis referral hotlines because patients cannot travel to hospitals on closed roads. Pharmacies in upland towns rationed electrolyte drinks for elderly residents coping with heat without fans.
