Unitywater is pursuing nutrient offsetting as a low-cost alternative to treatment plant upgrades that also enables us to protect human health and the environment.
At Yandina Creek, Unitywater will make the most of the natural processes by re-establishing the wetland environment and allowing tidal water from the river to enter the site. The wetland plants and micro-organisms in the soil will take up the nutrients like nitrogen and phosphorus from the tidal water.
Unitywater calculates how much nutrients the site will take up and this is incorporated into its treatment plant environmental licence limits. The end result? We meet our licence limits, public health is safeguarded, the environment is protected and we cater for growth, all thanks to a sensible strategy of letting nature take its course.
