Water Treatment for Utility Tunnels

Cable, sewer and service tunnels are built in tight, congested ground with limited plot for treatment. The water challenge is similar to metro tunnelling but the equipment must fit into far smaller spaces and relocate frequently.

Our Expertise: Utility-Tunnel Water Treatment

Treatment systems for cable tunnels, sewer tunnels and other utility infrastructure — compact, often unmanned plants for confined bores. We show it because utility tunnels need small-footprint, low-maintenance treatment that fits where space and access are minimal. Cable and sewer tunnels are typically driven in confined, hard-to-access bores where there is little room for a treatment compound. Our skid and containerised plants are sized to fit those constraints and run with minimal attendance, while still meeting the same discharge and reuse standards as a full metro scheme.

Confined, Congested, Mobile

Restricted Plot

Urban utility corridors leave little room for treatment, demanding compact, vertically integrated plant.

Frequent Relocation

Short drives and multiple shafts mean equipment is moved often, favouring skid and container formats.

Variable Inflow

Groundwater, washdown and grout-contact water arrive intermittently and mixed, requiring flexible treatment.

Compact, Mobile Treatment

Lamella Clarification

Inclined-plate clarifiers deliver large settling area in a small footprint for solids and turbidity.

pH & Oil Control

CO2 neutralisation and coalescing interception handle alkaline and oily streams before discharge.

Containerised Packages

Pre-assembled container plants deploy quickly and relocate between shafts with minimal site work.

Utility Tunnel Package

Mobile Lamella Units

Skid-mounted clarifiers sized for confined utility-corridor sites.

CO2 Neutralisation Skids

Self-regulating pH correction of concrete-contact water.

Self-Cleaning Filters

Compact polishing filtration ahead of discharge or reuse.
