Services - Grease Traps & Liquid Waste
 

Grease traps need regular cleaning to ensure solid grease does not build up and block the trap.  A build up of solid grease in the trap can cause damage to the trap or cause an overflow in the lines, resulting in damage to your property, or may allow grease to leak into the sewer system.  

Safety Tips:

  • Do not put any sort of chemicals, water, food waste, or other garbage into the grease tanks
  • Always check for fullness of tank or plugged screen before poring grease into the tank to avoid spills
  • If tank is full, call us immediately for service and have the grease removed
  • Clear the area around the tank to ensure that the driver does not have any problems in emptying the tank
