Work has started the southern parking lane along Te Aute Rd with two-way traffic flow to be maintained but speed restrictions and stop-go operators may be in place at times.
There will be restrictions to parking and cyclists in the southern lane.
If individual driveway access is to be interrupted, the contractors will make direct contact with affected residents in advance.
There will be some drilling along Te Aute Rd and through the Anderson Park carpark and trenching in the Anderson Park fields, timed to occur between the rugby and cricket seasons from late September until Labour Weekend.
Work on the Porter Drive roundabout will take about one week in mid-September, one side of the roundabout will be closed so full traffic management will be in place.
The construction is the beginning of a two-year programme of work upgrading drinking water infrastructure.
The work ensures the council is meeting safety, resilience, and sufficient capacity of supply for urban residents across Hastings and national drinking water standards.
Further work in the Havelock North area is planned for the next one to two years.
Drinking water services will be installed along Campbell St from Duart Rd and from Porter Drive through to the corner of Middle Rd and then along Middle Road through to Iona Road.
Stormwater services will be going in along Campbell St from Busby Hill, through to the Havelock North Bowling Club.
Both of these projects are to start early in 2021.
