The Sewer Department handles all sanitary manholes, including general maintenance and cleaning. They use a vactor truck to clean, unplug, and jet sewers. This department also repairs broken pipes.
All Village of Crete sewage is pumped to Thorn Creek Basin Sanitary District in Chicago Heights, where it is treated. The Village allocates approximately $230,000 a year for sewer repairs and maintenance. Projects such as video-taping sewer lines, cutting roots, and lining the inside of the sewer without digging them up are a few things that are done to maintain the sewer system.
