Septic tanks are crucial in on-site wastewater management, especially in places where centralized sewage treatment isn’t an option.
These buried tanks have a big job: they’re the cleanup crew for all the home and business wastewater. This includes dirty ‘grey water’ (showers, bathtubs, whirlpool tubs, washing machines, dishwashers and bathroom sinks) and ‘black water’ (toilets and kitchen sinks.)
Through a natural separation and biological breakdown process, septic tanks help remove solid waste and contaminants from sewage, allowing for the safe release of treated effluent into the soil.
Inside the tank, heavy solids sink to the bottom, forming a layer of sludge, while grease floats on top as scum. The in-between liquid, called effluent, gets broken down by bacteria. Once it’s somewhat cleaned up, the effluent heads out to a drain field or leach field, where it seeps into the soil, undergoing further purification.
So, septic tanks might be out of sight, but they’re definitely not out of importance – they play a vital role in keeping our properties and the land around them healthy and happy!
