Proprietary systems are manufactured stormwater best management practice (bmps) and treatment systems available from commercial vendors. These systems are designed to treat stormwater runoff and/or provide water quantity control. Most proprietary systems exist underground and are often used in areas where above-ground practices are not feasible. Proprietary practices include pretreatment and post-construction practices designed for permanent stormwater treatment. Though the distinction between different proprietary practices is not clear, we typically include manufactured treatment devices (mtds) as permanent post-construction practices.
This page (Category) includes links to pages that provide information on proprietary practices that are primarily mtds. But we include links to categories having information on pretreatment practices.
