Engineering Reliability Below Ground

Precision Water Management for Tunnelling Operations

Urban expansion and underground connectivity depend on precision-engineered tunnelling systems that operate efficiently while meeting stringent environmental standards. Our specialised water treatment technologies deliver reliable performance for the most demanding metro construction and tunnelling projects worldwide.

Underground construction presents unique water management challenges—from high-volume slurry processing to groundwater control and environmental compliance. Reynolds & Bauhm provides integrated treatment systems specifically engineered for tunnel boring machine (TBM) operations, deep excavation dewatering, and urban wastewater management.

Core Capabilities

Comprehensive Tunnelling Water Treatment

TBM Slurry Treatment Systems

High-capacity solids control and slurry recycling systems that maintain optimal drilling fluid properties, reduce waste volumes, and maximise operational efficiency during mechanised tunnelling operations.
