Yamba Septic Tanks
Choosing the right septic tank is critical when you want reliable wastewater management that meets health regulations and suits local soil conditions. At Shawline Plumbing and Drainage, we sell and install complete septic systems for homes and businesses across Yamba, Iluka, and Maclean, guiding you from product selection through to certified commissioning.
We assess your block, groundwater level, and household usage, then recommend a tank that balances capacity, durability, and budget. Our licensed team installs every component—tank, trenches, pumps, and filters—so everything works together seamlessly and complies with council requirements.
We make the process straightforward and transparent, so you feel confident about your new system from day one. Phone 0449 030 603 for expert advice and an obligation-free quote.
Installed the Right Way
A septic system is an investment expected to perform for decades, so we focus on long-term efficiency and low-maintenance operation. We use quality tanks engineered for Australian conditions, secure all pipework to prevent leaks, and ensure the dispersion area is sized correctly to protect your yard from soggy patches or odours.
Before finishing, we pressure-test lines, confirm fall gradients, and provide clear user guidelines covering everyday care, desludging intervals, and safe cleaning products. If you are upgrading from an ageing concrete tank, we handle decommissioning and disposal to keep your project worry-free and environmentally responsible.
When you want a septic solution that works quietly in the background year after year, reach out and let us design and install a system tailored to your property.
How do I know which septic tank size is right for my property?
Tank size depends on daily wastewater volume, which is influenced by the number of bedrooms, plumbing fixtures, and whether you run appliances like dishwashers or washing machines simultaneously. Local regulations also set minimum capacities—often 3,000 L for a three-bedroom home and larger for properties with extra bathrooms or high water usage. A licensed plumber will calculate design loading rates, soil permeability, and reserve area, then recommend a tank that comfortably handles peak flows without overload or premature pumping.
Do I need council approval before installing a septic system?
Yes. New installations and major upgrades require council approval to ensure environmental and health compliance. The application usually includes a site-and-soil evaluation, system design drawings, and engineer sign-off where needed. Approval must be granted before excavation begins, and final inspections are required before the system is commissioned. Licensed plumbers can prepare and lodge the paperwork on your behalf to streamline the process.
How long does septic tank installation take from start to finish?
Once approvals are in place and materials are on-site, most residential installations take two to three days. Day one covers excavation and tank placement, day two focuses on trenching, pipework, and connection, and day three is reserved for finishing, backfilling, and commissioning. Larger or more complex sites may extend this timeline, especially if dewatering, rock breaking, or electrical work for pumps is required. Proper curing time for concrete surrounds or access restrictions can also influence duration.
