New 9.8M BioCap® Digester Cover lifted into place for the Port Lincoln WWTP
SA Water’s upgrade of it’s Port Lincoln Wastewater Treatment Plant, led by Guidera O’Connor in 2020, included a new sludge management and processing facility installed at the site.

A new mesophilic anaerobic digester was included as part of the upgrade to enhance the plant’s environmental process and improve the quality of biosolids.
Hydroflux Epco together with Guidera O’Connor, completed the installation of the 9.8M diameter BioCap® Digester Cover.
A 100 tonne crane was used to lift the BioCap® Cover into place. With favourable weather conditions and thorough investigations prior to the operation, the installation was successful. The BioCap® Cover forms an integral part of the digestion process, providing storage of the biogas that is produced within the digester.
Ancillaries provided included pressure and vacuum breakers, a sampling hatch, and a seal water tank.
Hydroflux Epco have delivered over 80 BioCap® covers for plants across Australasia. Turnkey systems can be provided inclusive of mixing, heat exchange and gas/co gen handling technology.
