Serving Lismore & Surrounding Areas
A sewage backup is classified as a Category 3 water intrusion under the global AS/IICRC S500 standard. This is the most severe classification, representing grossly unsanitary black water. It contains pathogenic bacteria, viruses, and waste that pose a significant and immediate health risk to your family or employees. Here in Lismore, these events are not just a plumbing nuisance; they are a deeply serious environmental health issue, often linked to the immense pressures placed on our infrastructure.
At Water Damage Lismore, we do not simply “clean” sewage. We execute a strict, scientifically-grounded remediation protocol designed to safely remove hazardous materials, decontaminate building structures, and restore your property to a safe, pre-loss condition, compliant with NSW Health regulations.
Our IICRC-certified technicians are local to the Northern Rivers, equipped for immediate 24/7 deployment across the Lismore region. We were here during the 2022 floods, and we are here now. We understand the unique urgency when dealing with black water, whether it’s a failed pipe in a Girards Hill home or widespread contamination following a river swell.
The Reality of Sewage Contamination in Lismore's Floodplain
Sewage intrusions in Lismore properties are rarely random. They are deeply connected to our geography as a city built at the confluence of the Wilsons River and Leycester Creek. The record-breaking 2022 flood, which peaked at an unprecedented 14.4 metres, left a lasting impact on our city’s wastewater infrastructure.
Our fieldwork since the floods has identified clear patterns of failure:
- Sewerage Treatment Plant Overload: The February 2022 event caused catastrophic damage to the East Lismore and South Lismore Sewage Treatment Plants (STPs). This led to the discharge of untreated sewage into the Wilsons River, creating widespread environmental contamination and increasing the risk of backflow events long after the floodwaters receded. The ongoing repairs, estimated at over $100 million, mean the system remains vulnerable during heavy rain events.
- Compromised Pumping Stations: At least 12 sewage pump stations (SPS) across the Lismore CBD, North Lismore, South Lismore, and Girards Hill were inundated and rendered non-operational during the flood. Many are still operating on temporary solutions, creating a persistent risk of localised failures and backups, particularly when the ground becomes saturated.
- Alluvial Soil & Ground Movement: Lismore is built on alluvial river flats. These soils, while fertile, can become unstable when saturated, leading to ground movement. This shifting can shear old terracotta or earthenware pipes, common in pre-1980s homes in Lismore Heights and the CBD, causing collapses and blockages that are often only discovered when sewage backs up into a property.
- Post-Flood Debris: The immense volume of silt and debris carried by the 14.4m flood peak entered and clogged parts of the stormwater and sewer network. This has created chokepoints that reduce the system’s capacity and increase the likelihood of backups during subsequent, even minor, rainfall.
Understanding this local context is critical. Our assessment process goes beyond the immediate mess, aiming to identify the specific point of failure within this uniquely challenged local system to help prevent a recurrence.
Our AS/IICRC S500 Remediation Protocol for Northern Rivers Properties
We adhere strictly to the ANSI/IICRC S500 standard for professional water damage restoration, the globally recognized protocol for safely handling contaminated water environments. This methodical approach ensures the safety of all occupants and provides the detailed documentation required for insurance claims.
Initial Safety Assessment & Containment
Upon arrival, our priority is occupant and technician safety. We establish critical containment barriers using 6-mil antimicrobial poly sheeting to isolate the affected area. Negative air pressure is then established using HEPA-filtered air scrubbers to prevent the aerosolization and spread of airborne pathogens to unaffected parts of your home or business.
Contaminated Water Extraction
We use powerful, truck-mounted extraction units and submersible pumps to remove bulk sewage, water, and solid waste. This step is about rapid removal of the primary contamination source.
Removal of Contaminated Porous Materials
Any material that has absorbed Category 3 black water is considered non-salvageable. This includes materials like plasterboard (gyprock), insulation, carpet, underlay, and porous timber. These materials are carefully removed, double-bagged in hazardous waste disposal bags, and disposed of in accordance with NSW EPA guidelines.
Decontamination & Disinfection
This is a multi-stage process. First, all remaining structural surfaces are meticulously cleaned of all contaminants. Following the cleaning, we apply a TGA-approved, broad-spectrum botanical disinfectant designed to eliminate a wide range of dangerous pathogens found in sewage.
Structural Drying & Dehumidification
We deploy a specific configuration of IICRC-approved equipment, including Low-Grain Refrigerant (LGR) dehumidifiers and high-velocity air movers. This creates an aggressive drying vortex to remove the remaining moisture trapped in timber framing, concrete slabs, and other structural elements. Progress is tracked daily using thermal imaging cameras and non-invasive moisture meters until the pre-set drying goals are achieved.
Final Inspection & Handover
Once the structure is verifiably dry and decontaminated, we conduct a final comprehensive inspection. For sensitive environments or upon request for insurance validation, we can arrange for third-party post-remediation verification (PRV) testing by an independent environmental hygienist to confirm the area has been returned to a safe and sanitary condition.
Specialised Contamination Cleanup Services in Lismore
Our team is trained and equipped to manage the full spectrum of contaminated water events as defined by the IICRC.
Grey Water (Category 2) Intrusion Cleanup
Grey water, from sources like washing machine overflows or dishwasher leaks, is contaminated with detergents and biological matter. While less immediately hazardous than sewage, it can degrade into Category 3 black water within 24-48 hours. Our team responds quickly to extract the water, remove affected materials like carpet, apply sanitising agents, and establish a professional drying regime to halt microbial growth and prevent long-term damage.
Black Water (Category 3) Contamination Cleanup
This is our specialty. Black water from a toilet back-flow, a failed septic system, or an incursion of floodwater is grossly contaminated and presents a severe health risk. Our technicians wear full Personal Protective Equipment (PPE) and follow a strict, documented procedure for the containment, removal, and decontamination of all affected materials and structures, restoring your property to a safe, habitable condition in full compliance with the S500 standard.

Lismore Sewage Cleanup: Your Questions Answered
Your first priority is always safety. Evacuate all people and pets from the contaminated area immediately. If it is safe to do so, turn off the main water supply to the property. Do not touch any contaminated surfaces or items, and do not use household bleach or cleaners, as this can aerosolize contaminants. Call our 24/7 emergency line at 02 5633 0323.
The timeline is directly related to the extent of contamination and the types of materials affected. A small backup contained to a bathroom with a tile floor might take 2-3 days for full decontamination and drying. A more severe event that has saturated sub-floors, wall cavities, and multiple rooms could take 5-7 days or longer to ensure the structure is completely and safely dried.
Yes. Category 3 black water contains an array of dangerous pathogens, including E. coli, Salmonella, Hepatitis A, and countless other bacteria, viruses, and parasites. Exposure through skin contact or inhalation can lead to serious illness. This is why NSW Health guidelines mandate professional remediation by trained and certified technicians.
Yes. A core objective of our S500-aligned process is complete odour elimination, not just masking. The foul odour is caused by bacteria feeding on organic waste. By physically removing the source material, thoroughly cleaning all surfaces, and using specialized air treatment technologies like hydroxyl generators in the final stages, we destroy the odour at its source.
In our direct experience since 2022, the primary causes are failures in the municipal system from sustained rainfall, blockages in the mains, root intrusion into older private pipes, and pipe collapses caused by ground movement in the regions’ waterlogged alluvial soils.
