High Level Drinking Water Reservoir Aeration
Town of High Level
High Level, Alberta
After noticing that the Town of High Level was purchasing a lot of compressors from us, our team reached out to the operators to ask why they need so many new compressors.
Their operations staff informed us that their existing aeration system, which uses perforated bubbling airline stretched along the bottom of the pond, consistently required more air to make sure the entire length of the airline is supplied with enough air. Based on this information our team quickly determined the cause of the issues affecting their existing system. We also learned that High Level's drinking water reservoir was facing challenges with high manganese, hydrogen sulfide odours, and uncontrolled algae with their outdated aeration system.
Pond Pro/ AEC quoted an alternative system designed to eliminate the need to purchase several new compressor units every year and address their water quality concerns.
In 2016 our team installed a Can-Air Aeration system in High Level's drinking water reservoirs (13 diffuser in one reservoir and 7 diffusers into the other reservoir). Since the installation, town officials have reported low manganese levels, elimination of smell, and minimal algae growth.
Increase dissolved oxygen levels
Address high manganese concerns
Come up with a treatment plan for addressing annual algae blooms
Provide a turn-key system that will reduce mainetence and operating cost
We quickly determined a manufacturing error by our AquaTube supplier resulted in a lighter airline batch. The tubing was fully replaced as soon as a replacement batch was made (4 weeks)
System installation: August 2016
Some of the sinking airline installed floated.
Install a total of 20 Can-Air diffusers within reservoir cells 1 and 2
Cell 1: 650' x 400' reservoir
Cell 2: 850' x 850' reservoir
Install 9 KM 120C 1/2HP compressors (total system HP= 4.5; total system CFM @ 10 PSI= 43.2 )
Install custom lengths of AquaTube airline
Calculate pond volume to determine safe and effective algaecide treatment rates
The Town of High Level's water operators have reported increased DO levels (average ranging from 5.0-7.4 ppm), lower manganese levels, elimination of smell, and minimal algae growth.
