Palmerston North's Turitea dam is still nearly full as January draws to an end.

Water use in Palmerston North is soaring as warm weather continues and light drizzle hanging around the city barely registers on MetService's rain gauges.

On Monday the city used 32 million litres of water, up from a winter average of 25m litres a day.

Excluding the consistent 6m litres a day used by industry, the demand equated to 891 litres for each house, or 343 litres a person.

During winter, the average house uses 632 litres a day and the average person uses 250 litres – 93 litres less than they did on Monday.

City council infrastructure manager Robert van Bentum said the city's water stores were still good for the time of year.

The Turitea Dam, which provides two-thirds of the city's water, supplementing the bores, was 91 per cent full at the start of the week.

No hosing restrictions are in place, but the council is asking people to conserve water where they could.

"Whether we impose restrictions on outdoor water use will depend on whether we get heavy rain in the next month and whether demand remains steady or increases.

"Whatever happens, we need all Palmy residents to be careful with their water use. Every drop matters."
