Aerobic Treatment Units Explained

Some of the limited conditions include soil saturation, diverse types of soil, elevation of groundwater and proximity to waterways. Due to these conditions, aerobic treatment or mechanical units are more prevalent for installation. Aerobic treatment units (ATUs) will have similar configurations with a pumping station and chlorine contact chamber before discharge but will operate slightly differently than a conventional system.

 

Conventional Septic Systems Explained

To reduce the cost of collecting, processing and treating wastewater in some areas, the use of individual septic units or on-site wastewater treatment systems is a method of treating wastewater from household plumbing fixtures (toilet, shower, laundry, etc.) through more natural processes. Also known as decentralized wastewater treatment, these underground units use primary and secondary treatment to treat and disperse small volumes of effluent generated in residential settings. 

 

What Types of Wastewater Do You Generate

One of the largest factors for maintaining proper treatment of a decentralized septic system is the water volume that is flushed through the primary tank. The wastewater effluent is generated by a number of appliances including toilets, showers, sinks, dishwashers and washing machines. Wastewater can be classified as either “gray water” or “black water.” 

 

Effluent Reduction Guidelines: Alternative Treatment and Dispersion Techniques

When conventional absorption fields cannot be used, there are alternative methods for secondary treatment and distribution of effluent that can be utilized. The methods may vary based on parish but will mostly be due to local topography, available space, soil profile and water table elevation. Specific guidelines for alternative treatment and dispersion techniques regulations can be found...

 

Sanitation Guide for Limited-Use Septic Systems

Geographically, Louisiana’s coastal landscape provides ample opportunities for hunting, fishing, tourism and commercial industries. Though the impact of storms in recent years has dwindled coastal infrastructure and populations, many semipermanent camps or properties host activities throughout the year. A unique aspect of these locations is the wetland or marsh-based soil that lacks a foundation for permanent water infrastructure. 

 

Navigating Floods and Power Outages for Septic Systems

Louisiana has a history of impactful weather events which have negative consequences on infrastructure. Before hurricane season, take stock in preventative maintenance tips and get a checklist ready to get your septic system back online to reduce downstream water quality issues. A key to a healthy, efficient septic unit is a well-maintained system.

 

Preventative Maintenance Tips and Warning Signs of Septic Issues for Homeowners

Maintenance is key to the efficient performance of any sewage system. By emphasizing proper maintenance and the knowledge to recognize when issues may arise, you can reduce the risk of public health hazards and environmental contamination. To do this, homeowners should understand how the septic configuration operates and where problems can occur in the process.
