A Simple Guide To Septic Regulations in Alabama

In the dynamic landscape of property development, whether residential or commercial–especially in the scenic rural communities of Alabama–understanding septic laws and regulations is paramount for a  smooth building experience. Septic systems play a significant role in waste management in areas without access to centralized sewer systems and provide a localized solution for wastewater filtration and management.

Since septic systems are on-site wastewater treatment facilities, they are commonly used in rural areas where centralized sewer systems are unavailable. These systems comprise a septic tank and a drain field, working together to treat and disperse wastewater from homes and businesses. Proper installation and maintenance are essential to prevent environmental contamination and protect public health, which is where the septic regulations come in handy.

Permit Requirements

Before embarking on any construction project involving a septic system, obtaining all the necessary permits is crucial. The Alabama Department of Public Health (ADPH) oversees releasing septic system permits. Homebuilders and property developers must submit applications and plans for approval before commencing construction. This process ensures that the proposed septic system meets the state’s standards and regulations.

Professional Installation

Given its highly technical nature, Alabama emphasizes the importance of professional installation for septic systems. Property developers should engage licensed and certified septic system service providers, like Economy Septic, to ensure the system is correctly designed and installed. This ensures compliance with septic regulations and guarantees the system’s effectiveness in wastewater treatment.

Site Evaluation

Proper site evaluation is a fundamental aspect of septic system installation. The chosen site should be suitable for a septic system, considering soil type, topography, and proximity to water sources. In addition to ensuring the correct dimensions for your septic tank, the ADPH may require a site evaluation to determine the system’s viability and adequacy for the specific location.

Tank Sizing and Design

Septic tank sizing is a critical factor in your septic system’s efficiency. Regulations in Alabama specify the minimum size requirements based on the number of bedrooms in a home or the capacity of a commercial establishment. Based on CivilSir, a website on information relevant to civil engineers, “Typical standard dimensions of a 100-user commercial building septic tank should be 4 meters long, 1.5 meters wide, and 1.3 meters deep. There is a need for 1 to 1.5 ft of free space above the water level inside the septic tank, so the overall height should be 6 ft, including depth. [The tank] should have [a maximum] tank capacity of 7500 liters of liquid wastes.”

Additionally, the design of the septic tank should adhere to state guidelines to ensure effective waste separation and treatment. Off the bat, ADPH requires a septic tank to be watertight, with all its components corrosion resistant and “resist the effect of sewage, sewer gasses, household chemicals, and soil burial.” 

Moreover, the department requires a septic tank to have at least two compartments: “The baffle wall forming the two compartments shall be located so that the inlet compartment comprises approximately two-thirds of the effective liquid capacity of the tank.” ADPH further noted that they may require test reports from an independent testing laboratory to confirm a manufacturer’s tank design.

Setback Requirements

Under this regulation, setback requirements dictate the minimum distances between septic system components and property lines, wells, water bodies, and structures. These regulations aim to prevent contamination of groundwater and surface water. Understanding and complying with setback requirements are essential for a legally sound and environmentally friendly septic system installation process.

Regular Inspections and Maintenance

Regular inspections and maintenance are also crucial for the longevity and efficiency of septic systems. Alabama regulations often require periodic inspections by certified professionals to ensure the system functions correctly.

Before commencing the construction or refurbishment of a property, developers should communicate the importance of ongoing maintenance to homeowners, emphasizing the role of responsible waste disposal practices in ensuring the soundness and sustainability of your septic system.

Alternative Systems:

In some cases, standard septic systems may not be suitable for certain locations due to soil or site constraints. Alabama allows for alternative systems, such as aerobic treatment units or mound systems, which may be more suitable for challenging environments. However, these alternative systems must meet state standards and receive proper approval.

Educational Requirements:

Homeowners in Alabama must undergo educational programs on septic system care and maintenance. Property developers can contribute by informing homeowners about the importance of proper waste disposal, the signs of system issues, and the need for timely professional inspections.
