The $30 million plant was officially turned on last November but began discharge into the river as a trial last week, a council spokesman confirmed.
Contractor Haslin constructions has completed the work, designed to cater for the city's growth, projected to be 6000 people in the next 20 years.
Decommissioning of the old plant is almost complete. A report to Tuesday night's council meeting recommended that a tender be granted to Conhur Pty Ltd to "desludge and clean" two digestors at the plant for $448,700.
The digestors are 100 years old and half full of "undigested waste that is in a solid mass in the tanks," the report states.
"This is specialised work and is difficult due to the depth of the tanks," utilities director Marina Hollands wrote.
"(It) poses both environmental risk due to the nature of the material in the tanks and the work, health and safety risk due to a confined space and the gasses that will be present as the mass is broken down for removal."
The tanks are each six metres deep, with a combined 6ML capacity.
The council received two tender submissions for the work. A three-member panel recommended Hervey Bay based company, Conhur Pty Ltd, based on value for money.
