WATER & WASTEWATER
LAGOON DESLUDGING
TEMPORARY LEACHATE WATER CONTAINMENT
WHERE: Invermere Lagoon (Invermere, British Columbia)
WHERE: Beaver Municipal Landfill (Ryley, Alberta)
WHAT: Over time the accumulation of bio-solids in municipal lagoons affects holding capacity which requires desludging. In this project, Titan Tubes were used to remove bio-solid sludge with the objective of increasing the lagoon’s capacity. Slurry from the lagoon was pumped into approximately 6- 60’x100’ Titan Tubes, which were contained in a temporary sloped berm lined with 20 mil Titan TRP-200R geomembrane. As the tubes dewatered, the liquid flowed into a depressed sump area where it was pumped out and the bio-solids remained in the tubes for disposal after drying.
WHAT: Titan was hired to construct a new landfill cell at Beaver Municipal Landfill as part of an expansion project. During this time, the area experienced heavy rains that washed out containment berms in the existing cell. This caused leachate water to flow into an area of the new cell that we were constructing. An immediate solution was needed. Our custom-made Titan Tubes proved to be a quick and cost-effective way to contain this leachate water. The tubes were constructed on-site and successfully stored a total of 450,000 gallons of leachate water which was then treated and discharged into a storage pond outside of the landfill cell. The landfill kept the bags and stored them for re-use if required. WHY TITAN: We were asked to provide a quick solution to the unforeseen problem and were able to respond immediately. This was a valuable solution to the client as it prevented them from having to shut down their operation and allowed us to continue work on the new cell while minimizing delays.
WHY TITAN: Not only did titan supply the Titan Tubes but we
successfully completed the desludging project, which had been abandoned by the previous contractor, and offered value-added service by lining the temporary berm. Because of this and the client’s satisfaction with our work, we were later contracted to re-line the lagoon cell which we also completed successfully.
