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 m 3 /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 m 3 /h. During the construction phase, more than 140,000 m 3 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.

The NORDIWA 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.
