Underground septic tanks, on-site wastewater treatment tanks, and other waste storage or disposal systems can be made from a wide range of materials. Some of the more common you find in both residential and commercial properties are made from either concrete, steel, or a special type of heavy-duty plastic.
Residential And Commercial Septic Tanks
They are more common in various locations, where municipal sewer lines aren’t available. Though you might also find them on construction sites, mines, equipment yards, storage facilities, and certain commercial properties.
Many of these septic tanks are more than just tanks with a baffle or other internal components. Many include some form of the drain field, leach field, or leach drain. This is essentially a subsurface wastewater disposal system that is designed to remove contaminants and other impurities from the upper liquid component of the tank.
As this liquid goes through a process of anaerobic digestion in the septic tank, it gradually emerges from and enters the drain field. The organic materials in this liquid are then catabolized by either a natural or artificially maintained microbial ecosystem.
When properly maintained this type of “Septic System” with a tank and drain field reduces the need for pumping and can potentially reduce ecological problems. However, no tank can last forever. Baffles, seals, and even tank walls can corrode and crack. Improperly maintained systems can build up with physical material, flood, overflow, backup, and shorten the overall lifespan of the tank. When this happens the ecological impact and the liability of the property owner can be significant.
