Infiltration Basins: Standards and Procedures to Ensure Performance

Infiltration basins have been a common means of stormwater management across the United States, as well as internationally, for more than three decades. A large constructed soil basin—up to 50 acres in area—with a complex permeable base and engineered pretreatment inflow and sides is designed to allow stormwater to infiltrate into the soil within 72 hours of inundation. When planned, designed and constructed correctly, infiltration basins can function effectively for 15 years or longer. Unfortunately, a high percentage of infiltration basins fail well in advance of their planned service life. It is a widespread problem that has been addressed with standards, guidelines, manuals and definitive regulations over many decades. Yet, the high failure rate of infiltration basins persists. MnDOT’s Office of Environmental Stewardship sought to learn the best practices that other state agencies employ to mitigate infiltration basin failure and make corrections when failure occurs. This Transportation Research Synthesis presents findings from a literature search for relevant practices of other state agencies for the planning, design and construction of infiltration basins along with guidance from national organizations. It also investigated nongovernmental and international sources and research. There is a significant amount of literature on this subject. Standards and procedures appear to be clear and accepted, but essential preconstruction evaluations and procedures are not always followed. A survey of selected state departments of transportation sought further information concerning standards and procedures that agencies employ to construct effective infiltration basins, as well as their solutions to common challenges that arise in infiltration basin construction. The results of the survey follow the findings of the literature search.
