Until the rains return and temperatures continue to rise in Finistère, lawns, stadiums or even ephemeral gardens will no longer be watered. However, in order to save the 400 newly planted young trees, Brest Métropole has recently started using purified water from the port area, which is usually discharged into the port. They are not polluted but not drinkable. Watering these plants is done by tank on trucks and is possible from 6 to 10 am.
