FAQ

What causes septic or sewer drainage pipes to fail?
Common causes include tree root intrusion, ground movement, ageing materials, heavy vehicle traffic over buried lines, and blockages. Over time, these can lead to cracks, collapses, or backflow. Early signs include slow drains, wet patches outside, or sewage smells.
How do you repair broken sewer pipes?
Depending on the damage, we may repair the pipe directly or replace sections. Techniques include trench excavation, pipe patching, and full replacement. We also use CCTV to inspect the system and ensure the repair targets the root cause of the issue.
Do new drainage systems require council approval?
Yes. All sewerage plumbing and drainage work must comply with NT Health Department and council regulations. As a licensed and self-certifying team, FastCall Wastewater Solutions handles all the necessary permits and paperwork to ensure a smooth, compliant process.
