Septic Pump Repair & Replacement
If you have a septic system with a pump and the alarm is sounding, the tank level isn't dropping, or wastewater isn't being pumped properly, the problem may be the pump, floats, alarm, or controls.
Depending on the type of system, the pump may be referred to as an effluent pump, sewage pump, or grinder pump. Black Rock can diagnose the pumping system and determine what's causing the problem.

E/One Grinder Pump Installation in Greenback
Hired directly by the City of Greenback, Black Rock installed one new grinder-pump station, ran its discharge line to the utility service connection, installed the control panel, and performed startup. The work included approximately 30 feet of excavation through an asphalt parking lot; asphalt restoration was not part of our scope.
This installation was completed March 29, 2026. See the project photographs and scope for an example of our pump-system work.
