Failure to do so will mean it will likely breach the Government’s order to fluoridate by March 28, and a raft of consequences potentially kick in.
Weston said commissioning the Whangārei fluoridation would take nine working days.
Each water treatment plant had different fluoride delivery arrangements.
Fluoride would slowly start spreading through the council’s drinking water pipes and networks from the four treatment plants, at varying stages.
Hydrofluorosilicic acid or fluoride was ordered for Whangārei drinking water fluoridation from an international chemical company plant at Mount Maunganui on March 12.
Weston said people would start getting fluoridated drinking water from their taps at different times.
He said commissioning would see staff look to confirm a consistent fluoride dose of between 0.7mg/l and 1mg/l, with a target setting of 0.85mg/l.
Testing would look at the full functionality of fluoride dosing and monitoring and include checking safeguards.
Wednesday is the latest Whangārei District Council can start the nine-day job of introducing fluoride if it is to meet the Government’s March 28 legal deadline or risk jail, about $5 million in costs, and the potential for the appointment of Government commissioners or a council observer.
However, the introduction start-up could just as easily stop as another part in the ongoing saga’s jigsaw plays.
In the High Court at Wellington on Tuesday, legal proceedings initiated by the council will seek a pause to the operational processes of introducing fluoride.

Weston said special care would be needed when receiving fluoride. Hazardous materials procedures had to be followed and tanks and pipework double-checked.
Fluoride would be held in storage tanks. It would be transferred from those to day tanks and from there into the water system. Dilution systems would be checked.
Monday’s meeting, which is scheduled to be held in public, comes as a result of a canned meeting on Wednesday this week , where Whangārei Mayor Vince Cocurullo and Deputy Mayor Phil Halse attempted to hold its predecessor behind closed doors but were blocked by seven councillors.
