Wastewater Lagoon Sludge Removal Indianapolis

Lagoon Sludge Removal

It’s not unusual for municipalities to experience problems with excessive sludge buildup in their sewer lagoons. This type of project requires careful handling. Not only do we need to dredge and remove the material, but the sludge needs to be dewatered and disposed of properly, typically in a sanitary landfill.

Relying on Landfills Can Be Expensive

This process can be expensive for city municipalities, as landfills charge based on the weight of the material being accepted. Usually, the water content of sludge from wastewater lagoons is very high: roughly 98 percent water and 2 percent solids.

In the past, the drawback to hydraulic dredging has been the inability to control the large amount of excess water.

  • As you can imagine, the most effective way to reduce landfill costs is by eliminating as much water as possible from the sludge before taking it to the landfill.
  • Our treatment plant dredging process, utilizing geotextile tubes, coagulating polymers and flocculants, has made all the difference. This can dramatically reduce landfill costs for our clients.

Citizens Energy Group Water Treatment Plant Projects

Heartland Dredging has performed several projects for Citizens Energy Group in Indianapolis. The projects involved removing alum sludge from Citizens Energy Group’s many sediment lagoons. As usual, this material needed to be hauled to a sanitary landfill for permanent disposal. We initiated a process to do this without interrupting plant operations.

The water treatment lagoon cleaning process went as follows:

  • We removed the sludge and injected a polymer into the pipeline before the slurry reached the geotextile tubes.
  • The polymer promoted quicker separation of the solids and water.
  • The combination of the polymer and the geotextile tubes caused a significant reduction in the volume and weight by filtering out the water cleanly and leaving behind only the solid material.
  • Since the material placed in the landfill is measured by weight, Citizens has realized significant savings in disposal fees because of our method.
