Kirkalocka Mine Site Wastewater Treatment Plan

Kirkalocka Mine Site Wastewater Treatment Plan

In 2019, EEI was commissioned by Adaman Resources to assess the existing wastewater treatment plant for the West Australian Kirkalocka mine site and provide support in securing approvals from the Department of Water and Environmental Regulation and the Department of Health. EEI was able to investigate the current wastewater treatment system to identify potential flaws and inefficiencies in the existing process. With analysis on each inefficiency, EEI provided the service of developing multiple options to fix the relevant issues.

To prevent significant environmental damage to ground water and nearby water bodies, the plant’s wastewater required to be distributed and disposed of evenly over the environment, preventing a pooling effect of wastewater. The standard solution to this problem is an expensive subsurface leach drain system. However, EEI was able to apply fundamental engineering principles while considering the site environmental risk factors of the site to design an economical drainage channel system as opposed to a capitally intensive subsurface leach drain.

Accompanying this, EEI was able to develop a maintenance plan for the system. We determined if the wastewater treatment plant system and disposal area are maintained regularly and with an annual inspection by a certified environmental engineer, any repairs /faults fixed immediately, the system may have a service life of over 15 years.
