BE-05 Cleaning: Solids in Drain and Sewer Systems

Drain and sewer may only be used in such a way that any avoidable impairment of groundwater and water bodies is eliminated. The solid’s physical properties and the sewer system’s hydraulic condition dictate whether they will reach the sewer treatment facilities or be deposited in the sewer line. The latter is the subject of this module.

After completing this module, you will have a sound knowledge of:

• the origin of solids and their transport characteristics;
• the consequences of solids discharge for the operation and maintenance of drain and sewer systems.
