Problem: The Victor Hernández Building Elderly Housing facility in Aguadilla, Puerto Rico, had a failed onsite septic system in poor soils that needed weekly pumping to a holding tank. The limited area available, minimal budget for operations and maintenance and challenging wastewater typical of a project of this type, steered project designers toward a passive treatment system with a small footprint and the ability to meet treatment and economic needs.
Solution: Following thorough review of the project, Sani-Plant selected an NSF 40 and BNQ Certified Advanced Enviro-Septic combined treatment and dispersal system from Infiltrator Water Technologies. A 6,000 gpd system was designed with an additional septic tank that included a Septic Maze insert to increase the waste retention and allow greater primary treatment efficiency. Because the system is rigorously tested for high level treatment, it only needed a treatment and dispersal footprint of 5,609 square feet (39 1/2 by 142 feet) with an application rate of 1.07 gpd per square foot. Also, the project required only 2,600 feet of AES pipe in a butterfly configuration with eight serial sections. This saved the facility a significant amount of space.
Result: Victor Hernández Building saved significant short and long-term costs by installing a passive, small footprint CTD system with a proven record for exceeding required treatment levels.
