Upgrade to reduce pollutants
Woy Woy Wastewater Treatment Plant is to be upgraded to meet a pollutant reduction program imposed by its Environmental Protection Licence.
Gosford Council will enter into negotiations with a Sydney-based company for the design and construction of dewatering facilities as the first stage of the process.
Despite no tenders being accepted for the project, there were no commercial, cost and time advantages in recalling tenders, according to a council staff report.
Council resolved at its meeting on July 6 to enter into negotiations for the design and construct for dewatering facilities at Kincumber and Woy Woy plants with Abergeldie Young Process Engineering Pty Ltd as the firm lodged the most advantageous tender response and has extensive experience in delivering dewatering facilities.
Council also agreed that subject to satisfactory negotiations, the general manager be authorised to enter a contract with Abergeldie Young Process Engineering Pty Ltd.
"Gosford Council has committed to carrying out a Pollutant Reduction Program (PRP) under the current Environmental Protection Licence conditions, consisting of a series of upgrades to the Kincumber and Woy Woy Wastewater Treatment Plants," the council report stated. "These upgrades at a total budgeted construction cost of $35 million are required to be progressively completed within a set period of fixed milestones, the last of which is scheduled for September, 2012.
"As part of the PRP, Gosford Council proposes to upgrade the dewatering facilities at both sites to improve biosolids handling practices.
"Kincumber WWTP has an existing dewatering facility with a single belt filter press.
"Woy Woy WWTP has a trailer mounted belt filter press.'
"At both sites there is no redundant dewatering capacity.
"Both sites dewater directly from sludge lagoons with the sludge pumped via pontoon with pump/mixer arrangement.
"The dewatering facilities in this contract will replace the existing dewatering facilities and provide redundant capacity for the future to 2051."
