Septic Tank Type - New Hampshire - New Jersey - South Carolina

Onsite Wastewater Management Tanks
Septic systems are a critical component of decentralized wastewater management in America, particularly in rural and semi-urban areas. Designed for efficiency and durability, septic tanks provide a sustainable solution for households and industries where access to public sewers is limited. To meet diverse environmental standards and project needs, the septic industry provides a full spectrum of solutions. Tank Depot offers everything from robust, conventional two-chamber septic tanks for standard installations to advanced systems like the Norwesco/Snyder BioMicrobics with MicroFAST technology ATU, engineered for strict regulatory compliance in sensitive areas....

Our range of septic tanks provides reliable solutions for managing wastewater, designed to meet the highest local and federal standards of durability and regulatory compliance. Each type of septic tank is tailored to specific needs, offering versatility, capacity, and technical robustness. Selecting the right sewer tank depends on your specific application, soil conditions, and state regulations.

Septic Tanks Type

Single Compartment Septic Tanks
Single Compartment Septic Tanks

These are a straightforward, cost-effective solution for basic onsite wastewater treatment. The single chamber separates solid waste from liquid effluent, making them ideal for properties with a moderate waste load. The one chamber septic is also ideal for greywater or non-potable water systems.

Dual Compartment Septic Tanks
Dual Compartment Septic Tanks

Also known as two-chamber septic tanks, these systems provide enhanced wastewater treatment. By separating solids in two stages, they offer superior filtration and are a perfect choice for larger properties or areas with stricter environmental compliance requirements.

Septic Pump Tank
Septic Pump Tanks

Solves elevation challenges by pumping wastewater uphill to a leach field. Ideal for both high-volume residential systems and infrequent-use cabins, it features an integrated pump stand for stability. Note: Avoid installation in high water table or clay soil areas.

Multi-Use Underground Septic Tanks
Multi-Use Underground Septic Tanks

A highly versatile solution for septic waste, potable water (with FDA-approved resin), or rainwater storage. Its corrosion-proof polyethylene construction is a durable, low-maintenance alternative to concrete, with select models offering faster, cost-saving installation with no need for special backfill.

Aboveground Septic Tanks
Aboveground Septic Tanks

The ideal solution for temporary or permanent onsite wastewater storage where underground septic tanks are unfeasible. Perfectly suited for construction sites, seasonal cabins, remote properties, mobile job shacks, or in areas with high water tables and rocky soil.

Steel Underground Holding Tanks

Certain multi-use underground tanks are designed to be a key component for stormwater management, helping to control runoff and reduce flooding in urban and residential areas.

Septic Tank Regulations By State

Septic systems are heavily regulated in the USA to ensure proper wastewater management, environmental protection, public health, and groundwater safety. The type of septic tank you'll need—whether a single-compartment septic or dual-compartment system—is primarily determined by local regulations. These regulations take into account factors like wastewater load, water table level, soil composition, and property size to ensure optimal performance and environmental protection.

In areas with high water tables or poor soil absorption, above-ground septic tanks may be mandated. For larger systems, multi-use underground tanks might be recommended to meet specific design requirements.

Each state has its own regulatory framework, often managed by local health departments or environmental agencies, which set standards for septic tank materials, size, placement, and ongoing maintenance. Always consult with your local health department or a licensed septic professional to understand the exact requirements for your property before making any decisions.

Choose the Best Septic Tank for Your Property with Tank Depot

Septic systems represent a complex intersection of environmental science, engineering, and regulatory compliance. The materials and technologies used—whether polyethylene septic tanks for enhanced corrosion resistance or advanced treatment units for nitrogen removal—are pivotal in maintaining system efficiency and protecting groundwater from contamination. By incorporating aerobic treatment, biofiltration, and effluent monitoring technologies, modern septic solutions not only meet but often exceed local environmental standards.

Understanding the intricate details of each component—from the pumps and chambers to the drain fields—is key to designing and maintaining an optimal septic system that will perform reliably for decades.

Our septic tanks are compliant with state-specific requirements, ensuring optimal performance and long-term reliability. Filter by color, size, manufacturer, and product class to find the septic tank that suits your needs.
