Septic Tank Cleaning
Keeping your septic system clean is essential for preventing blockages, odours and overflow. We provide septic cleaning services that support system performance and extend lifespan. Our team clears buildup from inlet and outlet points, checks for solid waste accumulation and ensures your system is ready for pump-out when needed. Regular cleaning helps avoid system failure and keeps your household running smoothly.
Septic Tank Repairs
If your septic system is showing signs of trouble — like gurgling drains, wet patches in the yard or bad smells — we can help. We carry out targeted septic tank repairs to address leaks, cracked lids, blocked filters and damaged pipework. Using the right tools and practical experience, we restore your system quickly and minimise disruption to your property.
Septic Tank Installation
Installing a new septic system requires the right layout, local knowledge and attention to council requirements. We plan and install complete systems including the tank, trenching, and all required connections. Whether it’s for a new build or an off-grid upgrade, we make sure the installation supports your household needs and meets all environmental and plumbing standards.
What should you never put in a septic system?
Avoid flushing or draining items like wet wipes, feminine hygiene products, nappies, grease, oil, bleach, paint or harsh chemicals into a septic system. These materials can clog pipes, kill beneficial bacteria and interfere with the breakdown of waste inside the tank. Even products labelled “flushable” can cause damage. Septic systems rely on a balanced bacterial environment to work efficiently, so using septic-safe toilet paper and cleaners is essential to avoid long-term system failure.
How does a septic tank system work?
A septic system treats household wastewater by separating solids from liquids. Waste flows into the tank, where solids settle at the bottom (sludge), lighter materials float to the top (scum) and liquid (effluent) flows into a drain field. Bacteria in the tank help break down organic matter. The drain field filters and disperses the treated water into the soil. Regular maintenance is needed to prevent buildup and ensure the system continues working effectively.
Can heavy rain affect my septic system?
Yes, heavy rain can cause the ground around a septic system to become saturated, which prevents proper drainage from the tank’s leach or absorption field. This can lead to backups, surface pooling and foul smells. If the system can’t release treated water into the soil, wastewater may remain in the tank or back up into the home. Avoid doing laundry or running dishwashers during storms, and direct stormwater runoff away from the septic area.
