At Tuffnell Plumbing Drainage & Gas, we provide expert septic tank installations designed for long-term performance and compliance. From site assessment to system setup, our team of drainlayers handles every step—ensuring your wastewater system is installed correctly, safely, and built to last.
A poorly installed septic system can lead to leaks, ground contamination, bad smells, and costly drain repairs. Choosing the right system—and getting it installed correctly—is essential for reliable wastewater management. Whether you’re building new, upgrading an old tank, or replacing a failed system, proper installation ensures long-term performance and full compliance.
For rural homes, farms, or properties not connected to mains wastewater, a septic tank is a critical part of daily operations. If not installed properly, it can lead to drainage issues, council fines, or health risks. That’s why it’s important to work with licensed installers who understand system design, site requirements, and local regulations.
Tuffnell Plumbing Drainage & Gas specialises in septic tank installation for residential and lifestyle properties. We handle the full process—from site assessment to final connection—so you get a system that’s reliable, efficient, and built to last. Here’s what we do during a typical septic tank installation:
Small issues with your septic system can quickly lead to health risks, property damage, and costly repairs. Signs like slow drainage or foul smells near your drain field often point to system failure or poor wastewater system treatment. Early servicing helps prevent serious problems and keeps your system running safely and efficiently.
Overflowing or Flooded Drain Field
If you see pooling water, wet patches, or soggy ground near your drain field, the system may be overloaded or not absorbing wastewater properly. Strong odours and visible surface runoff are also key warning signs. These issues often point to a failing soakage area or saturated soil.
Unpleasant Odours Around the Tank or Land
Persistent foul smells near your septic tank, drain field, or inside your home often mean something is wrong. These odours could signal poor ventilation, system overload, or solids building up inside the tank. Smells that don’t go away are a strong indicator that servicing is overdue.
Improper or Outdated Installation
Recurring drainage issues, foul odours, or slow treatment performance could signal that your septic system wasn’t installed correctly or is no longer functioning as intended. You may also notice unusual water levels in the tank or ongoing compliance issues. These are common with older systems or poorly designed setups.
Blocked or Damaged Pipes
Gurgling sounds, repeated backups, or slow drainage in sinks, toilets, and showers can point to a blockage in the pipes connected to your septic tank. You might also notice wet spots or sewage smells in your yard. These issues are often caused by tree roots growing into cracked pipes, collapsed pipe sections, or joint failures due to ground movement or age.
If your current septic system is causing slow drainage, bad smells, or frequent backups, it may no longer be working properly. Routine pumping can help in the short term, but if problems keep coming back, it’s often a sign the system is outdated or wasn’t installed or maintained correctly.

Whether you’re upgrading or starting fresh, we’ll ensure everything runs efficiently from day one—and offer ongoing wastewater system servicing to keep it that way.

The costs involved in septic system installation in New Zealand typically range between $10,000 to $20,000, depending on your site conditions, soil type, tank size, and whether additional wastewater system servicing are required. Urban areas may face higher costs due to limited space and tighter local regulations. Rural areas can offer more flexibility, but access and land slope can affect the installation process. We’ll always provide a transparent quote based on your specific needs. For the most accurate pricing, we recommend a site assessment by our experienced team.
Choosing between a single chamber tank and a multi-stage wastewater treatment system depends on your household size, land area, and discharge requirements. Septic tanks for rural areas with more land might suit simpler setups, while urban areas often require advanced systems with further treatment stages. We assess key features like site conditions, soil permeability, and the volume of wastewater to recommend the best solution. Our goal is to install a reliable septic system that ensures safety and long-term performance.
The installation process starts with soil testing, system design, and obtaining the necessary permits from local authorities. Once approved, our team handles excavation, tank placement, drain laying, and land reinstatement. We ensure your system meets all local regulations for safe discharge and environmental protection. Every installation includes clear communication and professional assistance from start to finish.
For optimal performance, septic tank pumping should be done every 3–5 years depending on usage and tank size. Regular maintenance prevents system failure, unpleasant odours, and costly repairs. Proper cleaning also removes built-up organic matter and protects the soakage treatment area. We offer scheduled drain maintenance services to keep your system running smoothly and help you save money long-term.
Common complications can include poor soil drainage, rocky ground, or unknown underground services. Other factors such as tank location, access for heavy equipment, or high groundwater can impact the timeline or increase costs.
