How We Handle Your Septic Tank Plumbing Needs From Start to Finish

Our proven process ensures your system is installed correctly, maintained properly, and repaired quickly when issues arise.
Here’s what you can expect:

Step 1. Site Assessment and System Design

We start by assessing your property’s soil type, slope, water table, and council requirements. This helps us recommend the right tank size and treatment system for your needs, whether it’s a conventional setup, sand filter, or aerated wastewater treatment plant.

Step 2. Council Permits and Approvals

Installation requires permits from your local council. We handle all the paperwork, engineering specifications, and liaison with the City of Greater Geelong, Surf Coast Shire, or your local authority to get your approvals sorted without the headaches.

Step 3. Professional Installation or Repair

Our licensed plumbers use proper excavation techniques & Hydro Excavation to install your system to Australian standards. For repairs, we diagnose issues quickly using inspection cameras and pressure testing, then fix pumps, pipes, or treatment components with quality parts that last.

Step 4. System Testing and Commissioning

Before we leave, we test your entire system to ensure proper drainage, treatment, and compliance with regulations. You’ll receive documentation showing everything meets all requirements and is ready for years of reliable service.

Step 5. Maintenance Scheduling and Records

We set you up with a maintenance schedule based on your household size and system type. Regular pumping every three to five years prevents costly failures and keeps everything operating efficiently.

Step 6. Ongoing Support and Emergency Service

Wastewater issues don’t wait for business hours. We’re available 24/7 for emergency repairs when your system fails or backs up. Our team responds quickly to minimise disruption and get your household back to normal.

Frequently Asked Questions

How often should I pump my tank?

Most residential septic tanks need pumping every three to five years, depending on household size and water usage. Larger families or homes with garbage disposals may need more frequent service. Regular inspections help us determine the right schedule for your specific setup, preventing backups and expensive repairs down the track.

What are the signs my septic system needs attention?

Watch for slow drains throughout your home, gurgling sounds from pipes, bad smells near the tank or drainfield, wet patches or lush grass over the absorption area, or sewage backup in toilets and drains. These warning signs mean your system needs professional inspection straight away to prevent complete failure.

Can you install septic tanks on any property in Geelong?

Most properties can accommodate a system, but soil type, water table depth, property size, and proximity to waterways all factor into council approval. We conduct thorough site assessments and work with your local council to determine the best installation solution for your specific property conditions.

What types of systems do you work with?

We install, maintain, and repair all common types including conventional tanks, sand filter treatment systems, aerated wastewater treatment plants, UV treatment systems, and subsurface drip distribution systems. Our team stays updated on the latest technologies and regulations for each type.

How long does tank installation take?

Most residential installations take two to four days once permits are approved, depending on complexity, soil conditions, and site access. The permit process typically takes several weeks. We’ll give you realistic timelines upfront and keep you informed throughout the entire process.

What’s included in tank maintenance?

Regular maintenance includes inspecting the tank for leaks and damage, checking scum and sludge levels, pumping out accumulated solids, testing the drainfield, inspecting pumps and treatment components, and keeping detailed service records. Proper maintenance extends your system’s lifespan and prevents costly emergency repairs.
