AHO Infrastructure Mappings
-
Tin & co. conducting a mapping assignement through datasets from Vann- og avløpsetaten (VAV). For this work, Tin got into some slight trouble for multiple things: showing up unnanounced at VAV, acquiring confidential maps and for asking the questions for which two points in the city was the most vulnerable if a terrorist should attack.
The preliminary work for Sixty Feet.Part of the AHO course, Recycling Oslo, led by Space Group - in which got a few alarmed calls from VAV.

Data collection: Water distribution, pressure points, sewage mainframe, garbage strategy and garbage demographics. These mappings informs us in ways where traditional Geographic Information Systems (GIS) are insufficient.
Clean Water Distribution
The water supply in Oslo mainly derives from large systems of reservoirs north of Oslo municipality. In the end it all culminates in Maridalsvannet, Oset facility, which is the main source of Oslo. Skullerud provides the southern parts of Oslo because the Oset is insufficient. The smaller facilities such as Langlia and Alunsjøen seems insignificant by the percentage they provide, but are actually essential as the valley makes it impossible for Oset to support.
Data source: on the back of a water distribution pamphlet given to children in elementary school. The very same data that was not given by the Agency for Water and Sewerage Works (VAV) due to national security.
Pressure Zones
These values are the numbers plumbers, hydrologists, and government officials operate with during reconstruction and renewal of watermains.
Data source: Agency for Water and Sewerage Works (VAV). This data is limited, usually due to a confidentiality agreement and national security.
Sewage Mainframe
The main grid is where all sewage from the secondary and tertiary grid ends up in, before being treated and funneled into the Oslo Fjord. If an error should occur, the surplus sewage can be redirected to the main grid. If two strategical errors should occur on the main grid, what would happen then?

Waste to Energy Cycle
In the 00s, Oslo municipality voted for a new sorting system for garbage. Blue bags are for plastic, green for food waste and white for residual waste. This is a procedure that is easy to follow, but what happens to the garbage we throw out? The garbage truck takes the garbage to either Haraldrud or Klemetsrud for computerized sorting on a conveyor belt. Plastic is actually not recycled in Oslo, but travels great distances to Sweden and Germany for treatment. Food waste goes Ringerriket Biogas plant not far away. The residual waste stays in the incinerators generating heat to the inhabitants.
Data source: various web sites, pieced together through an investigation on shipments and addresses of garbage locations.
Garbage Volume
How much garbage the inhabitants generate garbage in different districts in Oslo. In 2013 The New York Times wrote an article summing up Oslo’s current predicament, about the inhabitants not producing enough garbage for the incinerating facilities. This is not uncommon as Northern Europe generate 150 million tons each year. The incinerating facilities however, can handle 700 million tons each year. Oslo is currently importing garbage from Leeds, England.
Data source: Agency for Waste Management (Renovasjonsetaten). Data extracted from statistics in a garbage pamphlet issued by the agency.
