Access for residents and service vehicles will be maintained and detour routes will be marked. It is expected that these closures will be in place for about four weeks.
The contractors advise that the St Aubyn and Windsor closures will only occur once the currently closed Terrace Rd is reopened, also timed for Monday.
Ada St is also due to reopen at the end of this week, on May 18, while the closed sections of Sylvan Rd and Queen St are due to reopen in mid-June.
Hastings District Council works and services committee chairman Kevin Watkins said managing the construction was a juggling act, with safety the top priority.
"We are working on more than four different sites across the length of the project, so the logistics are complicated.
"We are only closing sections where we absolutely have to, for the safety of the public, work teams and the residents living in the affected streets.
"A bonus is, however, that by closing sections of road, the work does go a lot more quickly, which means we can be out of there as soon as possible."
The $10 million project is a key part of the drinking water infrastructure upgrade plan being implemented by Council, which in turn is a critical part of Council's Drinking Water Strategy, designed to improve the resilience, capacity and flexibility of the drinking water supply network.
