Sydney plumbing extends beyond city sewer connections, with many properties relying on septic systems for wastewater management. These systems require correct use, regular maintenance and awareness of early warning signs to function effectively. Septic care forms part of a broader plumbing strategy that includes water efficiency, drainage management and compliance with local regulations. Older systems may require assessment or upgrades to meet modern expectations. By understanding how septic systems integrate with overall plumbing, property owners may reduce the risk of failure, protect the environment and support long-term system reliability.
