Sump pump systems are also utilized in industrial and commercial applications to control water table-related problems in surface soil. An artesian aquifer or periodic high water table situation can cause the ground to become unstable due to water saturation. As long as the pump functions, the surface soil will remain stable. These sumps are typically ten feet in depth or more; lined with corrugated metal pipe that contains perforations or drain holes throughout. They may include electronic control systems with visual and audible alarms and are usually covered to prevent debris and animals from falling in. | Sump pump systems are also utilized in industrial and commercial applications to control water table-related problems in surface soil.

The pedestal pump's motor is mounted above the sump, where it is more easily serviced, but is also more conspicuous. The pump impeller is driven by a long, vertical extension shaft and the impeller is in a scroll housing in the base of the pump. | The pedestal pump's motor is mounted above the sump, where it is more easily serviced, but is also more conspicuous.

Sump basins and sump pumps must be maintained. Typical recommendations suggest examining equipment every year. Pumps running frequently due to higher water table, water drainage, or weather conditions should be examined more frequently. Sump pumps, being mechanical devices, will fail eventually, which could lead to a flooded basement and costly repairs. Redundancy in the system can help to avoid problems when maintenance and repairs are needed on the primary system. | Sump basins and sump pumps must be maintained.

Float switches are used to automatically turn the sump pump on when filled to a preset level. Float switches must be clear of any obstructions within the tank. A float guard can be used to prevent the float switch from accidentally resting on on the pump housing, and remaining on. | Float switches are used to automatically turn the sump pump on when filled to a preset level.
