Education is the key to a sustainable on-site infrastructure. To that end we are always looking for ways to work with local trade associations, universities, and states to provide training material.

Today we finally installed the American Perc-Rite(r) drip system at the MOWPA training center in Ellicott City MD.

Built to Outlast a Mortgage.

The Perc-Rite® Drip Dispersal System is engineered for longevity. It's built to outlast a mortgage. A frequent looked over item when purchasing a home is your septic systems and how costly it can be to replace or maintain. Anaerobic drip systems naturally offer extended performance because they deliver low-volume, controlled doses of effluent over a large dispersal area. This precision dramatically reduces the risk of soil overload, which is a critical factor in long term system health. Surrounding soil acts as the treatment medium, so once its capacity is exceeded, performance declines and failures become more likely. Investing in anaerobic drip in the beginning will not only save you money, but a headache as well.

What sets Perc-Rite® apart?

Many companies focus on selling components, but American Manufacturing Company, Inc.'s Perc-Rite® system is a complete, pre-engineered dispersal system, not just drip tubing. Every system is designed with precision to support durability, predictable operation, and peak performance over time. System lifespan ultimately depends on proper design, soil evaluation, controlled dosing and ongoing maintenance but with proper engineering, this maintenance can be reduced significantly. Pressure-dosed systems, when correctly designed and installed, are built for consistent performance. With deep regulatory acceptance and a proven track record in performance and longevity, American Manufacturing delivers solutions designed to perform from front to end.

In 1993, a group of wastewater professionals traveled to Israel to explore how drip irrigation technology could be adapted for onsite wastewater dispersal. The trip was hosted by Netafim USA, the world’s largest drip irrigation pipe manufacturer, and brought together 25 professionals including regulators, engineers, developers, and researchers from across the United States. Participants included well-known wastewater researchers Dr. Rubin and Dick Otis, along with Tom Sinclair, the original Perc-Rite® patent holder. The goal of the trip was to help fill in the knowledge gaps surrounding drip dispersal systems and better understand how the technology could support long-term sustainable wastewater treatment in soil. This collaboration marked an important moment in the early development of Perc-Rite® drip dispersal systems and helped move the industry toward improved design practices and field evaluation of drip technology. Today, the research and discussions that began during that collaboration continue to influence modern drip dispersal system design and performance evaluation.

As drip dispersal technology began to develop in the early 1990s, researchers recognized that a better understanding of hydraulic loading rates was needed to ensure long-term system performance. In 1994, researchers Dr. Rubin and Dick Otis, working with Tom Sinclair, evaluated several drip dispersal systems in Georgia. The work involved examining existing installations and studying how wastewater moved through the soil over time. Their evaluation helped establish an important design approach for drip dispersal systems. The report concluded that time-dosed systems using drip tubing spaced two feet apart, with emitters serving approximately four square feet of soil area, provided sustainable performance. Following these evaluations, systems were installed using this configuration with residential-strength effluent. Field observations showed that anaerobic plumes were minimized to the area immediately surrounding the emitter, rather than spreading throughout the soil treatment area. These early findings helped shape the design guidance that continues to influence modern drip dispersal system installations today.

Sustainable development isn't just about the surface, it extends into the ground. In onsite wastewater systems, the soil is the final treatment environment. How effluent is introduced to that soil creates a direct impact on groundwater quality, nutrient movement, and long term environmental health. The first thing to come to mind when discussing responsible wastewater management is controlled distribution. When effluent is applied in measurable doses over a broad area, soil is able to maintain aerobic conditions that support natural biological treatment. This process reduces organic loading and helps manage nutrient migration before water reaches groundwater supplies. Hydraulic overloading, on the other hand, saturates surrounding soils, reducing oxygen levels, and ultimately compromising quality of treatment. As time goes on, this presents the risk of nutrient leaching and system failure. Sustainable design considers soil evaluation, dosing strategy, site impact, and long term maintenance. Smaller footprints, minimal site disturbance, preserved vegetation, and energy-efficient operation are contributive to responsible system performance. Groundwater is one of our most valuable resources. Thoughtful wastewater engineering ensures we protect it for future generations.
