The paper presents the progress made at the oxidation-ditch wastewater treatment plant in sub-arctic Alaska. The facility was inundated during the disastrous Fairbanks flood of August 15, 1967. Restarting the plant was performed soon thereafter and this report covers only that period until May 15, 1968. Consistent Biochemical Oxygen Demand removals in excess of 90 percent were achieved even when liquid temperatures as low as 2C were prevalent. No mechanical failures could be attributable to the cold environment when average air temperatures of -49C lasted for ten days. Nitrification by the activated sludge was completely inhibited at liquid temperatures below 10C.
