Essential System Maintenance.

Septic Tanks —

How a Septic Tank System Works: All household wastewater flows into the septic tank through an inlet pipe. Inside the tank, solid waste rises to the top and forms a scum layer, while heavier materials settle at the bottom as sludge. As organic matter breaks down, the partially treated effluent water flows through the tank and exits via the outlet pipe. From there, it enters the drain field, where it gradually seeps into the soil, completing the filtration process.

Grease Traps —

How a Grease Trap or Settling Tank Works: When wastewater enters the tank through the inlet pipe, grease and fats naturally rise to the surface, while heavier solids sink to the bottom. Inside the tank, baffle walls slow the flow, allowing time for proper separation. This design helps retain the majority of grease, oil, and solids within the chambers, preventing them from reaching the main wastewater system and causing blockages. Regular tank cleaning and maintenance is essential to keep the system working efficiently.

Wash/Sump —

How a Grease Trap Works: When grease-laden wastewater enters the grease trap through the inlet pipe, it flows through a series of internal chambers designed to slow the water and encourage separation. During this filtration process, solids settle in the first chamber, while grease and oils rise to the surface. The partially treated water then passes through to the final chamber and exits the tank via the outlet pipe, safely entering the wastewater system.
Regular grease trap cleaning is vital to prevent buildup and ensure smooth operation.

  • Earl was fantastic not only did he empty the septic tank he did alot of digging to find out why it was blocking and found a broken pipe very muddy work. He also got hold of a person to help me get the pipe fixed. Thank you.
