Organizations are obliged to ensure that any wastewater they produce can be discharged to the sewer without any adverse effects. Coarse particles and fats can clog sewers, affecting households and other businesses that discharge to the same sewer. Cleaning costs are usually recovered from the party that causes the initial problem.

Minimum measures must be taken to prevent clogged sewer systems. These measures range from using filter baskets in the production process in combination with an elementary static fat trap to mechanical systems that remove between 60% and 80% of the pollutants.
