A wastewater system is a significant yet essential investment for any community. A routine inspection enables municipalities to determine current conditions, including the current inclination, and plan maintenance thereafter.
Sewer inclination keeps liquids and solids moving at an appropriate speed in a gravity system, therefore it is a critical consideration for the design and maintenance of a sewer system.
If the inclination is not steep enough, the sewage slows down, resulting in clogs. If it’s too steep, water and solids can separate, causing solids to accumulate in the pipe.
So, what happens when the Pipeline Inclination isn’t right you ask? Namely, Backups, Clogs, Excessive Erosion, and Sags to name a few.
Orsco has a couple of solutions at our disposal to monitor and assess the pitch of any sewer line.
A sewer inspection crawler outfitted with an inclinometer can measure how the slope of a line changes over distance, revealing a pipe's bellies, offsets, and other features that can collect sediment and impede flow. Software such as WinCan is used to plot the results as a grade profile.
Laser scans generate 3D data that can be analysed to understand pipe ovality and other geometric anomalies resulting from slope problems.
Areas of low or excessive velocity can indicate that the slope is incorrect.
