Bombala and Adaminaby STP Chemical Dosing System Rectifications

⁠⁠⁠Council is seeking a suitably qualified and experienced contractor to address issues being experienced with the Sodium Hydroxide (Caustic) and Aluminium Sulphate (Alum) Chemical Dosing Systems in Bombala and Adaminaby Sewage Treatment Plants.

Ongoing leaks are being experienced with the Caustic and Alum Systems in Bombala and with the Alum System in Adaminaby.

The Alum system in Adaminaby is also experiencing issues with flow and freezing. These issues have stemmed from the use of incorrect, not fit for purpose materials in the first instance.

The Caustic Dosing System in Adaminaby requires full installation to connect the chemical storage tank to the two Bioreactors, including all electrical works.

Contractors must demonstrate the necessary expertise, experience, and resources to deliver the tendered works safely and efficiently with full compliance to all relevant standards.

Successful respondents will be appointed under a design and construct contract and must ensure all materials are fit for purpose and appropriate for the unique conditions of the alpine region.
