Over time, clogs can occur due to the accumulation of grease, debris, and objects that are not intended to be flushed down toilets or drains. These can block pipes and pump inlets, hinder flow, and cause backups or overflows. Sewage pumps and pump stations, which help transport sewage to higher ground or treatment plants, can fail due to motor, electrical or mechanical issues, and this can also lead to problems with flow as well as backups and overflows.
Pipes, or sewers, can become damaged due to age or external factors including tree roots or construction and this can lead to leaks, groundwater infiltration and system inefficiency. And sludge can build up in sewage treatment plants reducing efficiency of the important job of cleaning sewage for safe release.
Regular and routine inspection, servicing and maintenance of sewerage systems, and the plants which treat sewage, are essential for efficiency, proper and safe flow of sewage, wastewater and stormwater, reduced energy consumption and fewer costly repairs.
