Technical Tours

The wastewater treatment plant in Ytre Sandviken is being expanded and upgraded, with work projected for completion in 2015. The renovations will include some of the most compact processing units available on the market. The treatment plant will handle the wastewater for 44.000 population equivalents (PE) and treat up to a maximum of 2500 m3/h. The plant’s processing units will be established with Kaldnes® Moving Bed Biofilm Reactors (MBBR), Actiflo® and Actidyn®, with the MBBR basins having a depth of 9 m. Throughout the design and planning process, the focus has been on life-cycle costs, workplace environment, energy optimizing, and energy recycling. The treatment plant is situated in a network of rock caverns.

The wastewater treatment plant in Kvernvik is undergoing renovations, with work projected for completion in 2015. The treatment plant is built in rock caverns as a traditional active-sludge plant, but with deep aeration basins (depth of 10 m). Throughout the design and planning process, the focus has been on life-cycle costs, workplace environment, energy optimizing, and energy recycling. The plant will handle the wastewater for 56,000 PE and treat up to a maximum of 1,630 m3/h. During the construction phase, more than 140,000 m3 of rock were removed from the mountain. The plant now appears as new and the mountain has been covered with Giertsen tunnel-sealing, both to optimize the indoor environment and protect the equipment and workers.

Listed as a UNESCO World Heritage site, Bryggen—the old wharf of Bergen–is one of the most popular cultural monuments in Norway. Over the centuries, it has been threatened by low groundwater, settlement damage, and frequent flooding; during the last few decades, further imbalance to the structure has occurred. From 1979 to 2000, the groundwater level in the northeast area (close to the Radisson Blu Royal Hotel, Bryggen) has sunk by several metres, while the front part of the wharf has been repeatedly exposed to spring tides. An interdisciplinary approach has been established to find a solution.

The Project Neumannsgate and surroundings is an interdisciplinary collaboration between the water and wastewater departments in the municipality of Bergen, BKK network (energy provider), heating and BIR (waste company). It involves the establishment and renewal of infrastructure before it is covered by asphalt and other layers. What can and should be co-ordinated?

Examples from Projects Håsteinerparken and Løvstien shows the planning of separation municipality in Bergen. A project concerning a new walking path alongside the rock wall. Planning and finishing of the separation, reopening of water systems and floodways based on guidelines for stormwater in Bergen.


The conference invites you to participate in a number of workshops, where you can meet your Nordic colleagues and exchange your experiences. Please join in and share the challenges from you working day and learn what your Nordic colleagues are challenged by. The workshops will be on the following subjects: sewer management, stormwater management and wastewater treatment plants.

The workshops will take place parallel to the presentation sessions. You will at any time during the conference have the opportunity to participate in either a presentation session, a poster session or in a workshop on the subject that you work within, whether it is sewer management, stormwater management, wastewater treatment plants or management.

The workshops are based on the open space technology, known as “law of the two feet”. The principles are that you take responsibility for what you care about. If you at any time during the time on the workshop find yourself in a situation, where you are neither learning nor contributing, use your two feet, go somewhere else. Each workshop starts with a number of short presentations for inspiration.

When you have registered for the conference, you can participate in the workshops as you wish. No separate registering is needed for the workshops, please just join in.

Are you young and work within the water sector?

Tuesday evening we will meet in the hotel lobby at 20:00. After a short walk to a nearby restaurant we will share an informal meal. You pay for your own meal, but remember to register, so that we can make the necessary arrangements with the restaurant. This dinner is initiated by VA-yngre in Norway. We hope this is an exciting arrangement and a nice way to get to know YWP and other youngsters working with water.

Don’t miss the workshop for Young Water Professionals Wednesday November 4th 0900–1100: Would you like to help shape the water sector of tomorrow? Join us for an informal workshop, meet your fellow Nordic peers and help develop the YWP networks of the future.
