A sewage backup from aged terracotta pipes in a Bangalow cottage or floodwaters from the Brunswick River inundating a low-lying property brings more than just water. It delivers grossly unsanitary Category 3 black water. This water is contaminated with pathogens, agricultural runoff, and waste, posing a direct threat to health. We remember the 2022 floods, which left 817 homes in Byron Shire flooded, 468 in Mullumbimby alone. That event taught our community hard lessons about the reality of contaminated water.
Our work is a specialised black water decontamination service for the entire Northern Rivers region. It is grounded in the rigorous protocols of the Institute of Inspection, Cleaning and Restoration Certification (IICRC). This isn’t just about water extraction. It’s about methodical microbial remediation, ensuring the safety of your home, the structural integrity of your building materials, and the quality of the air you breathe. We have experience with everything from waterlogged subfloors in Suffolk Park homes near the Tallow Creek catchment to commercial premises on Jonson Street that were submerged in March 2022.
We know the feeling of watching the rain and knowing the drains can’t cope. Black water events, often triggered by intense rainfall overwhelming council systems or tree root intrusion in older hinterland properties, demand immediate containment. Our technicians are on call 24/7, with vehicles fully equipped for rapid response across the Shire, from Ocean Shores to the Byron Hills estate.
Our first job on-site is a rapid assessment using thermal imaging to trace the water’s path. We establish critical containment barriers to stop cross-contamination into unaffected areas of your home or business. We then begin the controlled extraction of bulk contaminants. This immediate action is the single most important factor in mitigating health exposure and preventing the progressive, destructive impact of black water on building materials like timber framing and plasterboard.
We follow a strict, documented procedure to ensure your property is returned to a safe, pre-loss condition. Here’s how we recently handled a sewage inundation at a rental property in Brunswick Heads:

Site Safety & Assessment
First, our IICRC-certified team geared up in full personal protective equipment (PPE). We used thermal cameras and non-invasive moisture meters to map water migration. We found it had soaked 600mm up the plasterboard walls in the bathroom and seeped under the hoop pine floorboards into the adjacent hallway, a common issue in older elevated homes.

Debris & Contaminant Removal
According to IICRC S500 standards, all contaminated porous materials had to go. This included the carpet, underlay, and affected sections of plasterboard. These materials were carefully bagged on-site for disposal according to Byron Shire Council and NSW EPA regulations. Porous items like these cannot be safely sanitized after contact with black water.

Extraction & Disposal
Our truck-mounted extraction unit removed all standing water and sludge from the concrete slab. This Category 3 liquid waste was captured directly into our sealed tank. It was then transported for disposal at a licensed liquid waste facility that services the Northern Rivers, such as Summerland Environmental or Clarence Valley Septics. We never dispose of contaminated waste in the local sewer or storm drains.

Structural Cleaning & Sanitisation
All remaining non-porous surfaces like tiles and semi-porous surfaces like the timber framing were meticulously cleaned. We then applied an appropriate hospital-grade antimicrobial solution to destroy lingering microorganisms like E. Coli.

Structural Drying
We established a controlled drying environment using multiple low-grain refrigerant (LGR) dehumidifiers and high-velocity air movers. The key here in Byron's humid climate is aggressive dehumidification. We monitored temperature, relative humidity, and the moisture content of the timber and concrete daily until our readings confirmed they had reached their "pre-loss dry standard."

Post-Remediation Verification
Upon completion, we conducted a final inspection and ATP testing to confirm sanitisation success. We provided the property manager and the insurance company with all documentation, including moisture maps, drying logs, and photos, to validate the works for their claim.
Untreated sewage and floodwater are a toxic soup of bacteria, viruses, and parasites. After the 2022 floods, we saw how quickly mould can colonize damp materials in our subtropical climate. Mould growth can begin within 24-48 hours, especially in damp, poorly ventilated subfloors or wall cavities.
Species like Stachybotrys (black mould) and Aspergillus thrive here, releasing spores and mycotoxins that can trigger severe respiratory issues, allergic reactions, and are especially dangerous for the vulnerable. Our process is designed to eliminate these microbial threats, following the IICRC S520 Standard for Professional Mold Remediation. This is not a simple cleaning job; it’s a public health necessity to protect your family, staff, or tenants.
Choosing a certified technician is your primary safeguard. The IICRC S500 (Water Damage Restoration) and S520 (Mould Remediation) are the globally recognized industry benchmarks. Our adherence to these standards means the work we do is correct, safe, and defensible for insurance purposes.
We have guided dozens of local homeowners and businesses through claims with major Australian insurers. Our comprehensive documentation, including moisture maps, psychrometric drying logs, and a detailed scope of works, provides the evidence they need. Our lead technicians hold multiple certifications, including Water Restoration Technician (WRT) and Applied Microbial Remediation Technician (AMRT).
Our mobile teams are based locally, ensuring a true rapid response throughout the Northern Rivers. We understand the unique challenges of the building stock and flood-prone geography here. We have direct experience in:
In the Byron Shire, it’s typically one of two things. First, flash flooding from extreme rainfall events overwhelming local catchments like the Brunswick River, Tallow Creek, or Belongil Creek. River and creek floodwater is always treated as Category 3 black water. Second, internal plumbing failures, often exacerbated by tree roots cracking old pipes or blockages in the council sewer main.
Absolutely not. We strongly advise against it. The health risks from bacteria like E. coli and airborne pathogens are significant. It is particularly unsafe for children, the elderly, and anyone with a compromised immune system.
For a standard residential sewage backup affecting a few rooms, the initial removal, cleaning and sanitising phase takes 1-3 days. The structural drying phase is highly dependent on Byron’s ambient humidity but typically takes an additional 3-7 days. We aim to get it dry as fast as scientifically possible.
It depends entirely on the type of timber, the finish, and how quickly we can start drying. Porous materials like carpet and underlay that absorb black water must always be removed and disposed of. For solid hardwood, there is often a good chance of saving it if we act fast. We’ve successfully dried and restored many local hardwood floors.
Immediate action is vital to protect your health and minimise long-term structural damage. Our phone line is monitored 24/7 for emergency dispatch across the Northern Rivers.
