The spokesperson said the council would be testing water quality extensively before lifting the boil notice and that residents might notice lower water pressure.
New Plymouth schools would be delivered 85,000 bottles of water this week.
Taranaki Civil Defence, with support from volunteers and other agencies, was co-ordinating the delivery.
Mayor Neil Holdom said it was a big help to families in the region.
"Areas affected by the damage caused to our supply network during ex-Cyclone Gita are still under a boil-water notice – and this will apply until our testing programme is complete.
"There's almost 100 primary and secondary schools and early childcare facilities receiving the water delivery, so the boil-water notice won't be a barrier to them opening again tomorrow, and our kids going back to school."
Michael Carr, Principal of Mangorei School and President of the New Plymouth Principals Association, said the delivery would be welcomed by the schools.
"Getting back into a normal routine is important for our students and our communities.
"I'd like to thank our wider school communities for their understanding and patience in recent days.
"Now water supplies have been restored for toilet facilities, the delivery of drinking water can mean we can get on with teaching our kids this week.
"Parents should check their school's social media or web pages to confirm they are up and running from Monday."
