TOPOGRAPHY AND WATER BODIES
The urbanization on the Tromsø mainland originally stopped at the line of altitude at which water could be supplied by sole gravity.
WHAT ARE THE MAIN CHALLENGES FOR WATER (AND SNOW) MANAGEMENT ON TROMSﾃ郎A?
drainage blocked by frost and snow
snow removal, storage and cleaning from pollutants
sea level rise and increasing extreme weather events

snow information
ESTIMATED TOTAL ‘NORMAL SNOWFALL’ NOV-APR: 1330MM = 532MM WATER
estimated total ‘normal snowfall’ on Tromsøya: 30 928 854m3
estimated total ‘normal snowfall’ within selected area: 5 433 490m3
estimated ‘snowfall’ for clearing within area of up to 521 000m3 on public roads alone
Tromsø kommune today removes an average of 45 000m3 snow to various depots
x 4000 of that an estimated 15-20 000m3 comes from our site
x 1800 currently an average of 14 000 m3 snow is dumped into Tromsøysundet every winter

pollution and handling
Streets, parking lots and additional pollutions coming from the airport and comercial areas characterize high level of pollution.
Snow coming from the roads in residential areas, private housing with higher infiltration and absorption of pollutants to the soils during melting season.
Rapidly rising temperatures and higher activity on the surfaces generate a substantial volume of meltwater witch then wash tremendous amount of acumulated winter debris from street surfaces.
