Catch Basin Inserts: The catch basin insert drain guards (often referred to as the witches hat) can be placed directly into drains for stormwater filtration. This type of stormwater control is built to catch debris, sand, and other contaminates while allowing only clean water to pass.
Gutter Guards: For curb, inlet, or gutter guards, a variety of drain products are available to block, filter, and protect water systems. These gutter guards include filters that are inserted into the drain, log-type items that can be placed directly in front of the inlet, and small pipes to block debris.
Combination Drain Guards: Also available are a couple of guards designed specifically for curb and street combination drains. These drain protection products work to cover both drains and effectively filter materials.
Drain Covers: In addition to drain guards, we also offer several covers that are designed to fit directly over top of the drain. These covers can include urethane seals which directly cover and block the drain, or filtering covers which allow water flow to the drain while removing contaminants.
Drain Guards as BMPs
Due to their high filtering and containment ability, these drain covers and guards have often been implemented as BMPs in Storm Water Pollution Prevention Plans (SWPPP). When installed correctly, these items typically filter out some of the following items:
Several models are also available with oil absorbing materials or microbial strips to additionally remove oil.
Many of these products have been known to help comply with:
- NPDES 20 CFR 122.26 (1999)
- TMDL (total mass daily load) Requirements
