What Are I/A Systems?
Innovative/Alternative (I/A) systems are advanced septic technologies designed to treat wastewater more effectively than traditional systems. They are often required in environmentally sensitive areas or when standard Title V systems aren’t feasible due to soil conditions, high groundwater, or small lot sizes.
Why Choose an I/A System?
Environmental protection: Better nitrogen and phosphorus removal to protect water resources.
Flexibility: Can be designed to fit challenging sites where traditional leach fields won’t work.
Regulatory compliance: Approved by the Massachusetts Department of Environmental Protection (MassDEP) for use under Title V.
Long-term value: Reduces the risk of system failure and costly environmental impacts.
Why Amex Construction?
At Amex Construction, we bring decades of Title 5 and septic system expertise to projects that demand advanced solutions. Whether your property requires an I/A system to meet local regulations or you’re proactively investing in environmental stewardship, our team has the experience to get it done right.
