Safety Week 2025 on the E6 Clean Water Project in Oslo: focus on emergency preparedness

During Week 21, the E6 Clean Water project in Oslo celebrated Safety Week 2025, featuring a full program dedicated to this year’s theme: "Emergency Preparedness." The initiative actively engaged all project personnel through hands-on drills and targeted training sessions to strengthen readiness and awareness in emergency situations.

Key activities included:

• fire safety exercises with extinguisher training;
• first aid courses, including defibrillator use and cardiopulmonary resuscitation techniques;
• fall arrest rescue simulations using safety harnesses;
• containment and disposal of oil and chemical spills;
• electric vehicle fire containment using fire blankets;
• training in the use of self-rescue devices and rescue chambers.

Exhibition spaces showcased various Personal Protective Equipment (PPE), with comparative demonstrations of safety goggles versus safety glasses. The program also included a focus session on how to properly fill out Safety Observation Cards to report safety-related non-conformities.

The week also featured moments of conviviality, with ice cream, sweets, and grilled food served, alongside team-building activities that involved the project workforce. Suppliers and subcontractors also participated, sponsoring the production of special edition T-shirts featuring a dedicated logo and slogan created for the occasion.

About the E6 Clean Water Project

The E6 Clean Water project is part of the new water supply system for the city of Oslo, which is currently reliant on drinking water from Lake Maridalsvannet. In its current state, any disruption to this system could have serious consequences for the city. The project includes:

• a 19-km water intake tunnel from Lake Holsfjorden,
• an underground water treatment plant in Huseby,
• and a water transfer tunnel running through the city.

Ghella, in joint venture with AF Gruppen, is responsible for building the potable water distribution system. This network will connect to the existing treatment facility in Oset, strengthening the link between eastern and western Oslo. Upon completion, the city will benefit from two independent water sources and an additional potable water conveyance system, ensuring greater resilience in the event of system malfunctions.
