NA-06 - Cleaning: Design Measures to Avoid Deposits
Semi-central sedimentation
Semi-central sedimentation includes “measures taken for the retention of solids within sewer networks”. For this purpose, sedimentation systems such as stormwater tanks or sedimentation shafts can be used to collect sediment from precipitation runoff and wastewater [SteinR08].
Where conditions permit, these systems can retain heavy solids through the use of settling basins while allowing lighter particles to pass.
