Grease Separator

Cafés, restaurants, and other premises where food is prepared discharge large amounts of grease with wastewater. The grease sticks to drainage pipes and causes blockages, which can lead to flooding and complicate treatment at wastewater treatment plants.

According to municipal regulations for water and sewage (ABVA), grease in large quantities may not be discharged into sewer lines. Therefore, most businesses that handle or produce food must have a grease separator or equivalent device. The property owner is responsible for ensuring that grease is not discharged into the sewer. A grease separator functions as a filter at the drain and collects the grease. The collected grease is classified as municipal waste and must be managed by the municipality or a waste contractor with a municipal contract.
