Septic Tank & Treatment Plant Systems Installation

---

At Dooley & O'Dwyer Plumbing we install septic tanks and treatment plant systems for commercial spaces and residential homes in the Colac Otway Shire and surrounding areas. 

This includes finding the perfect location for your tank, sizing and location of effluent fields and all excavations required. 

Our admin team can also take care of council permits which are required for all septic tank and treatment plant installations including obtaining a Land Capability assessment (LCA) if is required.
