How do I know if my septic tank needs replacing or repairing?
Signs include bad smells, frequent blockages, pooling water around the tank area, or unusually lush grass above the system. If your tank is older or showing signs of structural damage, it may need replacement. A licensed plumber can assess your system and recommend the right solution.
What’s involved in a sewage installation?
A sewage installation includes site evaluation, system selection, excavation, tank placement, connection to plumbing and drainage lines, and final inspection. At FastCall Wastewater Solutions, we manage the entire process—including council approvals—to ensure your system is installed correctly and ready to use.
How long does a septic installation or repair take?
Most standard septic installations can be completed in 2–3 days, depending on the complexity and site access. Repairs usually take less time, especially if the issue is identified early. We’ll always give you a realistic timeline and keep you updated throughout the process.
