4. Design and build

Trevi designs and builds water treatment plants ranging in size from 5m³ per day to 15.000 m³/day utilizing different techniques. The design stage covers layout plans, electrical schematics, piping drawings and PLC programming. Our mechanical and electrical designs are implemented by our own site coordinators and technicians. The execution stage includes laying pipes, installing technical equipment (e.g. pumps, mixers etc.) and instrumentation (e.g. measurement devices), building and connecting the electrical cabinets etc. We do all of this work entirely in-house. Trevi only works with outside contractors where civil construction engineering is required, and in these instances they are trusted partners.
