What are poly pigs primarily used for in sewage maintenance?

Poly pigs are primarily used in sewage maintenance to clean sewer force mains. These devices are designed to be propelled through the pipelines by the flow of wastewater. As they move, poly pigs scrape the interior surfaces of the pipes, effectively dislodging buildup, grease, and other debris that can accumulate over time. This cleaning action helps maintain pipeline integrity, prevents blockages, and ensures optimal flow capacity within the sewer system.

The design of poly pigs allows them to navigate bends and turns within the force mains, making them an efficient tool for ensuring that these crucial components of the sewage infrastructure remain operational and free of obstructions. Regular maintenance using poly pigs not only aids in the longevity of the sewer systems but also contributes to overall sanitation and environmental protection by minimizing the chances of sewage spills or backups.
