Gisborne city's water shortage problem deepened today as the District Council moved to a higher water alert and banned the use of domestic sprinklers.
Water levels in the Mangapoike dams are lower than they have been at this time of year for 15 years and now half the water flowing out of taps comes from the emergency back-up source, the Waipaoa River.
Niwa's long-term weather forecast predicts dry conditions in the district over the next three months.
Council water team leader Marcus Koll said the council viewed the situation very seriously.
"City water consumption has been high since December, particularly when it comes to garden watering," Mr Koll said.
