Lecture: Introduction to challenges in water management in cold climates

Author/Compiled by
Harsha Ratnaweera, NMBU

Executive Summary

Cold climates represent challenges to water management uncommon to warmer climates. Water distribution and wastewater transportation systems need to consider freezing threats, and most treatment processes will have a lower capacity and treatment efficiencies. These challenges are even more emphasized with the impacts of Climate Change.


Factsheet Block Body

Cold climate water management gets even more complicated as the climate changes. Ecosystems will be altered, arctic populations will be affected by changing fisheries and an increase in tourism due to easier access. Global warming and increased precipitation leads to increased pollution in raw water sources used for drinking water, and wastewater treatment plants receive increased quantity due to snow melting and precipitation.
