What is a septic tank?

Septic tanks serve as the first line of defense against wastewater pollution from homes, gathering all interior plumbing into one sewer line that leads to your septic tank located usually somewhere in your yard.

Your septic tank holds all of your household wastewater until microorganisms can break it down and decompose it. Wastewater is separated into three distinct layers within your septic tank: fats, oils and anything lighter than water are collected in the scum layer on top; wastewater layer contains clear liquid; while the bottom sludge layer collects solid waste that settles to the bottom before eventually being broken down by microorganisms.

Maintaining a septic tank properly to avoid premature failure requires good upkeep and prevention of non-biodegradable items from being flushed into your toilet, such as cigarette butts, cotton buds or swabs and menstrual hygiene products that do not break down easily. Trees and shrubbery must also remain away from both your septic tank and drainfield to prevent root intrusion that could create serious issues with its functioning.

How does a septic tank work?

Septic tanks are underground watertight containers made of concrete, fiberglass or plastic designed to collect domestic wastewater for basic sewage treatment. Bacteria present in the tank digest organic material while simultaneously separating out solid waste from liquid waste – this effluent eventually leaving through an exit pipe into either a drain field or soil absorption system.

Heavy materials, like fats, oils and greases float to the top of your septic tank and form a layer of scum; while lighter material such as toilet paper and feces sink to the bottom and form a layer of sludge. A baffle wall separates these two layers to prevent them from draining out into your drain field or leach field and clogging pipes and leach fields.

Install an effluent filter in the septic tank outlet baffle to reduce odors and protect groundwater pollution by flushing non-biodegradable materials such as cigarettes, cotton balls/swabs, menstrual hygiene products into your system – these non-biodegradable materials could clog your septic system and lead to groundwater pollution.

What is a septic system?

All wastewater from toilets, sinks, showers and bathtubs, washing machines and dishwashers runs into a main drainage pipe leading directly into your septic tank. Solid waste sinks to the bottom while fats, oils and greases float to the top where anaerobic bacteria break them down into gases and liquids.

Liquid wastewater then flows from your septic tank through a perforated pipe and into a drain field, where it seeps through layers of gravel to be naturally processed by soil and grass below it.

Advanced septic systems work differently and use pumps or gravity to ensure their effluent trickles through a mixture of sand, organic material, constructed wetlands or other media that trap disease-causing pathogens as well as nitrogen and phosphorus in wastewater, while percolating back into native soil or being absorbed or evaporated back into groundwater – though such advanced systems require a larger drainfield than their traditional counterparts.

What is a septic system design?

Engineered septic system designs provide high-performance wastewater solutions specifically engineered for your property. Engineered designs include advanced treatment units that clean effluent to a higher standard before discharging into drainfields – protecting homes or commercial buildings from soil and groundwater contamination.

Septic system designs follow a precise process from soil testing to permit acquisition, making selection of an experienced design professional who understands your area critical for creating a seamless project and long-lasting wastewater solutions.

An effective system should include monitoring components that keep an eye on everything from water levels and pump cycles, to ensure everything works as expected and avoid costly repairs. Doing this ensures your system keeps performing as it should!
