Open air sand filters are a specialized type of Stormwater Control Measure (SCM) that stand out due to their unique design. Unlike bioretention cells, they lack plants, mulch, or turf, and are specifically maintained to remain vegetation-free on the surface. Recently, our team at Triangle Pond Management completed a project in Raleigh, North Carolina, where we addressed an open air sand filter that was failing to drain properly. This type of issue is not uncommon and typically occurs when these devices are not maintained correctly over time.

We often encounter open air sand filters that fail due to improper construction at the time of installation. The most common problems include undersized or incorrectly wrapped underdrain systems, and the use of inappropriate media. These mistakes can lead to either complete or premature failure of the system.

If you are responsible for maintaining an open air sand filter, it’s crucial to partner with a contractor who thoroughly understands their design and construction. Triangle Pond Management has been a trusted name in SCM installation and maintenance, including open air sand filters, for nearly 20 years. Our team is fully certified and has a proven track record of delivering high-quality work.
