Lagoon Cleaning and Dredging

Over time, wastewater lagoons can accumulate solids to the point of excess. The removal of biosolids is essential to keep lagoons operating efficiently and in compliance.

Lagoons suffering from excess biosolids can present these problems:

  • Decreased detention time
  • Insufficient digestion
  • Lagoon odors, which can indicate:
    • Low dissolved oxygen, leading to hydrogen sulfide production
    • Excess biosolids buildup on the lagoon bottom
    • High effluent BOD/TSS/TKN/TP
  • High fecal coliform
  • Algae and vegetation growth

Stewart Spreading’s team of experts works with municipalities, commercial/industrial businesses, agricultural producers, general contractors, and engineers and is ready to apply innovative solutions for your lagoon-cleaning projects. We have trained professionals and the proper equipment required for lagoon volume reduction, lagoon cleaning, or EPA lagoon closeout.

Time is valuable, so we work with our clients to best fit their timeline in order to minimize disruptions to operations. All EPA reporting and compliance is performed in-house to make the entire process as easy and stress-free as possible from start to finish.

Stewart Spreading’s trained professionals will utilize specialized equipment to provide lagoon volume reduction, lagoon cleaning, or an EPA lagoon closure. Once removed, when necessary, lagoon solids are screened to remove debris that are unsuitable for land application and then are transported to area farms for land application. This mutually beneficial process results in a cleaner lagoon for the client and natural fertilizer for the soil and crops of the agricultural producer.
