Technical Tours
Ytre Sandviken wastewater treatment plant
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 lifecycle costs, workplace environment, energy optimizing, and energy recycling. The treatment plant is
situated in a network of rock caverns.
Kvernevik wastewater treatment plant
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.
Bryggen: from imbalance to balance
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.
Graveklubben (digging co-ordinators) in Bergen
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?
Separation in the rainiest city of Europe
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.
Social Programme
Welcome Reception
Welcome reception on November 4th will be held at the Radisson Blu Royal Hotel, Bryggen.
The conference dinner
The conference dinner will take place at the King´s banqueting hall Håkonshallen on November 5th.
Håkon´s Hall is 750 years old and was built by King Håkon Håkonssons during the time Bergen was
Norway´s largest and most important town.
Are you young and working with water?
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.

Conference
The Nordic Wastewater Conference has been held every
second year in the Nordic countries since 1989. In
November 2015 it will be hosted in Bergen, Norway.
This years conference is organized by Norwegian Water
(Norsk Vann), in co-operation with the Swedish Water and
Wastewater Association (Svenskt Vatten), organises the 13th
conference, the Danish Water and Wastewater Association
(DANVA), the Finnish Water Utilities Association (FIWA), the
Icelandic Energy and Utilities (Samorka), and NORDIWA.
The conference is aimed at personnel and managers of
sewers, water and wastewater works, consultants, suppliers
and contractors in the sector, scientists and authorities.
