Slurry Treatment Plant Manager

FCC Construction Inc.

Manhattan, NY • On-site

$190K - $230K/yr

Full-time

Re-posted 20 days ago

Key responsibilities

  • Lead the setup, commissioning, operation, maintenance, troubleshooting, and demobilization of the Slurry Treatment Plant and associated systems.

  • Manage multi-stage separation and filtration processes to remove excavated material and maintain production throughput.

  • Monitor and control slurry properties, optimize chemical dosing, and coordinate with other operational teams to support tunnel boring operations.

Job description

The Slurry Treatment Plant (STP) Manager is responsible for the planning, setup, commissioning, operation, maintenance, optimization, and demobilization of the Slurry Treatment Plant and associated support systems for major tunnel boring operations. This role ensures that slurry separation, filtration, water treatment, chemical dosing, spoil handling, and related plant operations are performed safely, efficiently, and in alignment with TBM production requirements.

The STP Manager will lead plant operations to maintain continuous TBM advancement, optimize slurry performance based on ground conditions, reduce downtime, manage plant crews and vendors, and ensure compliance with project specifications, environmental permits, safety standards, and operational KPIs. 

The STP Manager’s key responsibilities are:

  • Lead the setup, commissioning, operation, maintenance, troubleshooting, and demobilization of the Slurry Treatment Plant and associated systems, including pumps, screens, shakers, hydrocyclones, centrifuges, filter presses, tanks, pipework, conveyors, controls, and water treatment systems.
  • Manage multi-stage separation and filtration processes to continuously remove excavated material from bentonite/water slurry mixtures and maintain required production throughput.
  • Monitor and control slurry properties, including density, viscosity, sand content, bentonite concentration, chemical dosing, and water quality, to support tunnel face stability and TBM performance.
  • Optimize chemical dosing programs, including bentonite, polymers, coagulants, flocculants, lime milk, and other additives based on ground conditions, production requirements, and cost efficiency.
  • Coordinate closely with TBM operations, mud pump systems, conveyor systems, grout batch plant operations, construction teams, and engineering staff to avoid production bottlenecks and maintain uninterrupted excavation cycles.
  • Review and interpret geotechnical data, TBM production forecasts, process flow diagrams, P&IDs, technical specifications, method statements, and operational requirements to identify risks and optimization opportunities.
  • Establish and maintain operating procedures, start-up/shut-down sequences, emergency response plans, contingency plans, risk assessments, and safe work procedures for STP operations.
  • Lead troubleshooting and root-cause analysis for plant performance issues, including pump cavitation, pipeline blockages, screen blinding, centrifuge performance, chemical treatment inefficiencies, excessive wear, water treatment challenges, and reduced throughput.
  • Track and report key performance indicators, including plant availability, slurry quality, throughput, water reuse, waste volumes, chemical consumption, equipment downtime, MTBF/MTTR, maintenance performance, and cost trends.
  • Manage preventive and corrective maintenance programs, including lubrication, inspection schedules, critical spares, repairable-spares loops, replacement parts, and vendor/OEM support.
  • Oversee procurement and inventory of critical plant components, including slurry pumps, screens, cyclones, filter press components, pipework, valves, sensors, instrumentation, chemical additives, and consumables.
  • Manage and mentor plant operators, mechanics, electricians, technicians, and specialist subcontractors, ensuring proper staffing, training, shift coverage, and adherence to operational procedures.
  • Prepare and maintain plant documentation, including SOPs, inspection records, maintenance records, commissioning documentation, KPIs, lessons learned, training materials, and regulatory reporting.
  • Ensure compliance with all applicable safety, environmental, and quality requirements, including OSHA, MTA, NYC, project-specific procedures, water discharge permits, waste disposal protocols, dust/noise controls, and confined space/LOTO requirements.
  • Support continuous improvement initiatives to increase reliability, improve maintainability, reduce waste, optimize chemical consumption, improve plant layout, and reduce operating costs.
  • Coordinate with project leadership, engineering, EHS, quality, procurement, and construction teams to support safe and efficient tunneling operations.
