With the U.S. wastewater treatment market projected to exceed $123 billion, developers are turning to modular and decentralized systems to move projects faster and smarter. At Caltech Environmental and NexGen Septics, we deliver advanced modular wastewater solutions, including the Advanced Enviro-Septic®, Delta ECOPOD-N, and Eljen GSF systems. These scalable, high-performance solutions provide up to 99% contaminant removal in a compact footprint — perfect for new subdivisions, multifamily communities, PUDs, trailer parks, and commercial developments. Unlike traditional treatment plants that take years to build, our modular systems deploy in months, reduce costs, and align perfectly with California’s updated 2026 Building Standards and CalGreen requirements. Whether you need passive treatment or engineered aerobic units, we provide full-service design, permitting, and installation across Northern California. Ready to accelerate your next project?
