Liquid Waste And Vacuum Trucks at Billiard South.

Service Requirements at Billiard South

Liquid waste management and vacuum truck services at Billiard South are shaped by the site's Channel Iron Deposit geology and its associated dewatering infrastructure — a network of 26 headworks and bore installations feeding a 900mm transfer main. This subsurface water management complexity generates sustained volumes of process-contaminated water, pit dewatering discharge, and hydrocarbon-laden waste streams that require licensed collection, haulage, and disposal under a structured service cadence. The open cut extraction method exposes multiple active bench faces simultaneously, creating dispersed waste generation points that vacuum truck contractors must be configured to service across variable haul distances within the pit envelope. Hamersley Iron – Yandi Pty Limited (subsidiary of Rio Tinto Iron Ore) requires all liquid waste contractors to operate under documented waste tracking and chain-of-custody protocols aligned with WA environmental licence conditions. Scope documentation should specify licensed liquid waste haulage capacity per single mobilisation (minimum 15,000 litres per unit) as a minimum performance threshold.

• Fleet vacuum capacity: Minimum 15,000-litre payload per vacuum truck unit; contractor must demonstrate availability of ≥2 compliant units deployable to site concurrently within the mobilisation window
• Pilbara ambient performance: All vacuum pump systems, hose assemblies, and tank seals must be rated and demonstrated operational at sustained ambient temperatures of 45°C, with documented performance data at peak conditions of 48°C
• Waste classification coverage: Contractor must hold current WA Environment Protection Authority (EPA) licences covering Category 1–3 liquid waste streams including hydrocarbon-contaminated water, sewage effluent, and chemical process waste, with evidence of compliant disposal at a licensed receiving facility within the Pilbara region

Site-Specific Operational Constraints

Conditions procurement must communicate to all bidders in tender documentation for Billiard South.

• Environment: Sustained summer ambient of 45°C with peaks to 48°C accelerates hose degradation, seal failure, and pump cavitation risk; red-dust abrasion from iron ore fines causes measurable wear on filtration housings and suction line components — specify red-dust abrasion filtration wear rates and replacement intervals in the RFQ to establish a maintenance baseline
• Logistics: Billiard South sits approximately 1,071 km from Perth; the nearest service hub is Newman (~75 km via haul road corridor); all contractor equipment and consumables must be road-transportable to site via the Hamersley Iron haul road network, with no assumption of scheduled freight availability — contractors must demonstrate self-sufficient parts inventory for a minimum 14-day unresupplied operating window
• Response SLA: Unplanned liquid waste events (pit inundation, hydrocarbon spill containment) require a 2–4 hour emergency call-out response from Newman hub; scheduled pit dewatering and camp waste services operate on a 12–24 hour extended mobilisation cycle confirmed by site supervisor; both SLA tiers must be documented in the contractor's mobilisation plan
• Roster: FIFO access is via Paraburdoo or Tom Price aerodrome; vacuum truck operators must be rostered to align with site FIFO cycles (typically 8/6 or 14/7 patterns); standby crew coverage during roster changeover must be specified in the contractor's workforce plan to eliminate service gaps during crew transitions
• Camp/facilities: Site-provided accommodation availability is not confirmed for this scope; contractors must submit a self-sufficient camp capability statement or confirm pre-existing accommodation arrangements within the Newman hub as part of their tender response

Contractor Capability Checklist

Minimum evaluation criteria for shortlisting Liquid Waste & Vacuum Trucks contractors at Billiard South. Each criterion must be verifiable via documentation submitted with tender response.

• Technical certifications: Current WA Environment Protection Authority liquid waste carrier licence; vacuum truck units compliant with AS 4825 (tanker design) or equivalent; documented pump and hose assembly ratings for sustained 45°C ambient operation
• Personnel tickets: WA Heavy Vehicle licence (HC minimum) for all vacuum truck operators; Dangerous Goods (Class 9 liquid waste) transport endorsement; site traffic management induction evidence from a comparable Pilbara open cut operation
• Mobilisation SLA: Documented evidence of 2–4 hour emergency response capability from Newman or equivalent Pilbara hub, drawn from at least one reference engagement at a comparable remote iron ore or bulk minerals operation within the last 36 months
• Public Liability insurance: Minimum AUD $20M per occurrence (Certificate of Currency required)
• Professional Indemnity: Minimum AUD $10M aggregate — applicable where contractor provides waste stream classification advice, disposal route specification, or environmental compliance recommendations
• Workers Compensation: Full statutory cover under WA law (WorkCover WA — Injury Management Plan required)
• Site exposure: Minimum 24 months demonstrated Pilbara site exposure within the last 5 years, specifically on open cut iron ore or equivalent hard-rock/bulk minerals operations; evidence must include waste volume throughput records and client reference contacts
• Safety systems: ISO 45001-certified HSE management system or documented equivalent; ICAM-trained incident investigation capability required given the hazardous nature of liquid waste streams in confined pit environments; Rio Tinto Critical Risk Management Program (CRMP) familiarity must be evidenced at supervisor level

Regulatory & HSE Framework

Applicable framework under the Work Health and Safety Act 2020 (WA) and the Work Health and Safety (Mines) Regulations 2022 (WA), administered by WorkSafe WA. Liquid waste haulage and disposal activities at Billiard South are additionally governed by WA Environment Protection Act 1986 licence conditions specific to the site's pit dewatering and waste disposal infrastructure. Contractors must maintain current EPA carrier registration and present compliant waste tracking manifests for every load cycle. Rio Tinto's HSEC Standards and Critical Risk Management Program — accessible via riotinto.com/sustainability — set the overarching HSE obligations binding on all site contractors. Hamersley Iron – Yandi Pty Limited (subsidiary of Rio Tinto Iron Ore) manages supplier compliance and contractor engagement through Rio Tinto's supplier portal ecosystem, which includes SAP Ariba for sourcing events and Avetta for safety and workforce prequalification (portal access via connect.avetta.com/login/riotinto); portal registration is mandatory prior to RFQ participation. All contractors must complete site-specific induction via Hamersley Iron – Yandi Pty Limited (subsidiary of Rio Tinto Iron Ore) procedures before mobilisation.

Sourcing Qualified Contractors

No confirmed tender activity for this specific scope is on record at the time of this briefing. The regional contractor pool for liquid waste and vacuum truck services in the Pilbara is limited: the WA Mining Index identifies approximately five active providers servicing mining operations across the region. Given the specialised EPA licensing requirements, the heat-rated equipment specifications, and the remote logistics profile of Billiard South, this shallow market depth warrants early engagement — procurement teams engaging this market should allow a minimum of 8–10 weeks for prequalification, Avetta onboarding, and equipment compliance verification before planned mobilisation. Contractors with demonstrated experience on iron ore operations utilising extensive pit dewatering infrastructure — analogous to the bore and transfer main configuration at this site — represent the highest-value shortlist candidates. No incumbent contractors are confirmed for this scope; the evaluation process must therefore be conducted without reference to prior site performance data, placing greater weight on documented Pilbara reference engagements and equipment certification at tender submission stage. Require contractors to demonstrate ≥24 months Pilbara site exposure within the last 5 years as a non-negotiable prequalification gate, not a scored criterion.
