When it comes to managing wastewater efficiently, septic systems play a crucial role, especially in areas where public sewer systems aren’t accessible. But what exactly is an engineered septic system, and how does it differ from traditional systems?
Understanding Septic System Engineering
Engineered septic systems are advanced wastewater treatment systems designed to efficiently process and treat household sewage. Unlike conventional septic systems, which rely solely on natural processes for wastewater treatment, engineered systems incorporate advanced technology, pressure distribution and other specialized components to enhance treatment efficiency and ensure even dispersal.
One of the primary distinguishing features of engineered septic systems is their reliance on advanced treatment units and pressure distribution. Some residential systems and all commercial systems require an Engineered design. Commercial systems can range from something simple like a day care to a restaurant or brewery. Wastewater strength and composition guide the design of the treatment system while the flow is the primary driver for the dispersal system. Engineers can pick from off the shelf systems by various manufacturer’s or design treatment systems from scratch. Sometimes a combination of available systems and scratch design are the best option for complicated or high strength waste. These components work together to optimize the treatment process, ensuring that the final product is adequately treated before being dispersed into the soil or discharged into a stream. .
Key Components of Engineered Septic Systems
Engineered septic systems typically consist of several key components, each serving a specific function in the wastewater treatment process:
- Septic Tanks: Similar to traditional systems, engineered septic systems usually include a septic tank where wastewater initially flows and begins to digest by anaerobic processes. In the tank, solid waste settles at the bottom, while oils and grease float to the top, allowing the clarified sewage in the center to exit the tank.
- Flow Equalization: The waste generated by a church, a school, a restaurant and an office building can vary by strength and flow. A church may have a peak load on the weekends while a school or office building has little flow on the weekend. A restaurant may be busier at night and on the weekend with little flow in the mornings. Treatment systems work best when the effluent being treated is consistent in strength and flow so capturing large flows and storing them to be “trickled” into the system usually results in better treatment.
- Treatment Unit: Engineered systems can use septic tanks only for treatment but usually e feature a treatment unit that further processes the wastewater before dispersal. The3se units may include advanced filtration, aerobic treatment, recirculating media filters, fixed fil bioreactors and chemical or UV disinfection. Other specialized components might be used for high fat or other high strength or unusual wastewater. Final treatment levels depend on the soil, state and local regulations.
- Pump Chamber: Most engineered systems are pumped to the dispersal field. Where the dispersal field is located uphill or pressure distribution is needed, designs incorporate a pump chamber and pumps to facilitate the transfer of the sewage to the dispersal area.
- Distribution System: Engineered septic systems ordinarily utilize distribution systems such as low pressure, enhanced flow or drip irrigation to evenly distribute treated effluent into the soil for final filtration and absorption.
Benefits of Engineered Septic Systems
Unlike traditional conventional systems, or residential alternative systems that do not need pressure distribution, engineered systems can overcome limited design options, engineered sand can be customized to suit site-specific conditions and accommodate varying wastewater loads. Engineered systems meet or exceed regulatory standards for wastewater treatment, ensuring compliance with local health and environmental regulations.
Why Hire a Professional Company for Engineered Septic Systems
