Alternative septic designs are systems that extend beyond the traditional septic tank and drainfield configuration to accommodate challenging site conditions or achieve higher treatment performance. They are typically implemented when factors such as poor soil quality, limited space, or high groundwater levels make a conventional system impractical.
Types of Alternative Septic Designs
There are many types of Alternative Septic Systems. In Arizona, Aerobic treatment units (ATUs) are common. They introduce oxygen to promote bacterial activity that breaks down waste more efficiently, similar to a municipal treatment plant on a smaller scale. Another is drip distribution systems deliver treated effluent slowly through tubing buried in shallow trenches, allowing for even dispersal and absorption. The choice of system depends on factors such as soil type, lot size, slope, and environmental sensitivity, ensuring each design provides effective and sustainable wastewater treatment.
Presby System Design
Presby systems focus on engineered septic solutions, including aerobic treatment and sand filtration systems, designed for challenging sites such as small lots or areas with high groundwater. They are highly customizable to meet local regulatory requirements while ensuring reliable wastewater treatment.
Delta System Design
Delta specializes in high-performance aerobic treatment units that provide efficient wastewater treatment in compact spaces. Their systems are designed to handle sensitive environmental conditions while maintaining compliance with strict effluent standards.
BioMicrobics System Design
Bio-Microbics offers modular aerobic treatment units and packaged wastewater treatment solutions for residential and commercial applications. Their systems integrate pretreatment and effluent polishing, providing versatile, reliable, and widely supported wastewater management options.
Eljen System Design
Eljen focuses on innovative drainfield solutions that use geotextile panels instead of traditional stone and pipe. These lightweight, easy-to-install systems are particularly effective in areas with poor soil conditions or limited space, minimizing excavation while ensuring proper effluent absorption.
Norweco System Design
Norweco produces advanced aerobic treatment units and disinfection systems designed for high-efficiency wastewater treatment. Their solutions are engineered to meet stringent environmental standards, making them ideal for sites where effluent enters sensitive waterways or requires enhanced treatment.
Ultimately, the best septic or wastewater treatment system depends on your property’s specific conditions—soil type, lot size, groundwater levels, and local regulations all play a role. Reaching out to a septic design professional early in the house-building phase can be especially cost-efficient, helping you avoid expensive modifications later and ensuring the system is properly tailored to your site. Consulting early provides long-term peace of mind, regulatory compliance, and reliable performance.
