Gosford City Council has announced the completion of $7.3million worth of work to the Woy Woy and Kincumber Sewage Treatment Plants (NSW).
The work included upgrades to the ageing aeration systems at both treatment plants.
Gosford City Council Director of Construction and Operations, Stan Antczak, said the new aeration systems will help treat the region’s 15billion litres of sewage each year.
“The aeration system plays a vital role in the secondary treatment process by using naturally occurring bacteria along with oxygen to break down organic matter found in sewage,” Mr Antczak said.
“We’ve now replaced the existing, out-dated aeration equipment with more energy efficient equipment, installed new technology to give our operators better control over the process and significantly reduced energy costs.
“These upgrade works will improve the reliability and capacity of each aeration system as well as make sure we can continue to comply with our environment protection licence and meet future population demands.
“Plus the use of new fine bubble diffused aeration at Kincumber is much safer and cleaner for our staff than the old surface aerators.
The Kincumber Sewage Treatment Plant has been operating since the mid 1980’s and currently treats most of Gosford City’s sewage – servicing around 130,000 residents and treating close to 30million litres on average, each day.
The Woy Woy Sewage Treatment Plant was commissioned in 1982 and currently treats about 10million litres of sewage every day from around 40,000 residents on the Peninsula – including Pearl Beach and Patonga.
“Sewage treatment might not be one of the prettiest jobs, but it is one of the most important services council provides for the community,” Mr Antczak said.
“Upgrades at the Kincumber and Woy Woy plants will always sit on top of the list to ensure we continue treating the community’s sewage to the highest environmental standards possible.”
In 2014 and 2015, Gosford City Council invested over $27million to improve Gosford City’s extensive sewage network, which includes around 1,500km of pipelines, over 180 pump stations and two treatment plants.
