A grinder pump “station” consists of the pump, a tank, and an alarm panel. A pump for household use is usually 1 hp, 1.5 hp or 2 hp. A cutting mechanism macerates waste and grinds items that are not normally found in sewage but may get flushed down the toilet.

What cannot be flushed down your toilet?  

• Baby wipes or cleaning wipes     
• Feminine/Male products
• Diapers
• Fat / Oil / Grease (FOG)
• Paint
• Paper Towels
• Cotton or Fabric
• Bandages / Plasters
• Contact Lenses

How to determine if your grinder pump station isn’t working properly?

• An alarm will trigger the red light on top of the panel to turn on
• Hear beeping noise
• Possible gurgling/bubbling noise can be heard in your pipes
• Possible overflow from the grinder pump station

 What to do if your grinder pump alarm is flashing or making a noise.

• Please call the Wastewater Department immediately at (615) 672-3654
• STOP using water in your home.
• Do not flush the toilets, run the dishwater, use a washing machine, or have a shower because this could cause the septic tank to fill up and send wastewater back up through the pipes and into your home.
