Iluka Septic Tanks

Living off mains sewer in Iluka means your septic tank has to handle coastal soils, high water tables, and seasonal rain without a hitch. Shawline Plumbing and Drainage has more than forty years of local experience designing, supplying, and installing complete septic systems that keep wastewater safely contained and compliant with Clarence Valley Council rules. We help you choose the right concrete or poly tank size, arrange soil tests, and handle all council paperwork, so approvals glide through.


Our licensed crew excavates neatly, sets the tank on a compacted base, and lays trenches to correct fall so effluent disperses evenly without surfacing. We pressure-test every line, fit durable filtration, and supply easy-to-follow care guides to maximise system life. Locals pick us for honest advice, tidy worksites, and installs that perform reliably for decades.

Built for Long-Term Performance

Our septic installations start with a thorough site inspection: we map soakage areas, check groundwater depth, and look for tree roots that could invade pipes later. Once the design is set, we schedule work around your routine, use compact machinery to minimise yard disruption, and recycle excavated soil where possible. Tanks are anchored to prevent float-off during floods, and each trench is wrapped in geofabric to stop sand clogging the line.


After commissioning, we run flow tests and explain pump-out schedules, eco-friendly cleaning products, and simple habits—like staggering washing loads—that keep bacteria healthy inside the system. You’ll receive digital as-built drawings for easy reference and reminders when routine maintenance is due.


With clear communication, trusted suppliers, and workmanship guaranteed by a second-generation local team, we make septic tank installation in Iluka straightforward from first call to final sign-off.
