Maclean Septic Tanks
Maclean’s clay soils and seasonal river flooding mean a dependable septic system is essential for long-term property health. Shawline Plumbing and Drainage brings over 40 years of local experience to designing, supplying, and installing septic tanks that keep wastewater safely managed and fully compliant with Clarence Valley Council regulations. We start by helping you choose the right concrete or poly tank size, arrange soil-percolation tests, and prepare all paperwork so approvals move quickly.
Our licensed crew then excavates neatly, sets the tank on a stable base, and installs trenches at the correct fall to prevent surfacing effluent. Every line is pressure-tested, filtration fitted, and backfilled to protect against root intrusion and ground movement. Maclean property owners trust us for honest advice, tidy worksites, and systems built to handle heavy rain and high water tables.

Start to Finish Support
We begin every Maclean installation with an on-site assessment, mapping soakage areas and checking groundwater depth to ensure the system suits your block’s unique conditions. Once the design is finalised, compact machinery minimises lawn damage while precise trenching guarantees even effluent dispersal. Tanks are anchored to prevent buoyancy during floods, and geofabric-wrapped ag-pipe stops clay from blocking lines.
After commissioning, we run flow tests, supply digital as-built drawings, and explain simple maintenance habits—like staggering laundry loads—that keep bacteria healthy and pump-outs infrequent. Our team coordinates electricians for pump connections and handles council inspections, so you stay informed without lifting a finger.
With clear communication, quality materials, and a workmanship guarantee from a second-generation local business, choosing Shawline means your Maclean septic system is installed right the first time and ready for decades of reliable service.
How do I choose the right size septic tank for my home?
The right septic tank size depends on your household size, water usage, and property layout. In Maclean, homes typically require a 3,000 to 5,000-litre tank, depending on bedrooms and fixtures. It’s best to plan for future usage too—like adding a second bathroom or guest space. Oversizing can reduce the frequency of pump-outs and improve system life. A licensed plumber can recommend the best fit and ensure the setup complies with Clarence Valley Council regulations.
How long will a septic tank system last in Maclean?
With proper installation and maintenance, a septic tank system in Maclean can last 20 to 40 years. Concrete tanks often last longer than poly, but both perform well when installed correctly and pumped out regularly. Local conditions like heavy rainfall and clay-based soils can impact longevity if the system isn’t properly designed for the area. Choosing a professional installer ensures your system is built to withstand Maclean’s environmental challenges and continues working efficiently for decades.
Can I replace an old septic tank without redoing the entire system?
Sometimes, only the tank needs replacing—especially if the existing pipework and absorption trenches are still functioning well. However, Maclean’s dense soils and ageing infrastructure can lead to drainage issues, root damage, or trench failure. A licensed plumber will carry out a detailed inspection to assess the system’s overall condition. This helps determine whether a partial upgrade will meet current council standards or if a full replacement is the safer and more cost-effective option long-term.
