Water as process equipment

In a steel plant, water is a process fluid carrying megawatts of heat. The engineering habits that come from that apply to treatment plants too.

03Plant engineering

We arrived at water treatment through cooling circuits: seawater systems, closed and open loops, and the balance-of-plant piping that keeps a furnace inside its thermal envelope. The instrumentation and control thinking transfers straight to municipal and industrial treatment work.

More recently that has extended to intelligent P&ID development, where the diagram becomes a live data model of the plant rather than a drawing that goes out of date the week it is issued.

// What this covers

What we do in this sector

01

Intelligent P&ID

P&ID development as structured plant data, used for operation and maintenance rather than only for construction.

02

Cooling & treatment circuits

Open and closed cooling circuits, seawater systems, heat exchangers, blow-down and water treatment for industrial plants.

03

Plant engineering

Process, piping, structural and control engineering for treatment facilities.

Where we have done it

Gipuzkoako Urak (Spain, 2025): development of intelligent P&IDs for water treatment plants. Tata Steel IJmuiden (Netherlands): seawater cooling system with structural design, buildings and pipe racks, 2023-26. Water treatment and cooling engineering for a German steel plant (2025), and a fume treatment plant detail design for the Karachi project (2026).
