Building #3 is a sanitary sewer lift station located at 709-10 Street.

Lift stations move water from lower to higher elevations. Once the water is lifted high enough, it can continue flowing by gravity. Wastewater from nearly all of Cold Lake North flows into this building. The area of collection spans from east of 16 Street (2 Avenue to 21 Avenue) to the eastern city limit. Approximately one million liters of wastewater is received at Building #3 every day. That’s almost 700 litres every minute. There are two pumps inside this building that pump 150 liters of wastewater per second. The pumps alternate about every five minutes. The wastewater is pumped nearly a kilometer to a manhole, where gravity then moves it to Building #4.
