There are two categories of parking deck drainage:
- outdoor drains exposed to the weather
- inside parking decks protected from the weather
Both types have to cope with heavy loads, moisture, and the accumulation of water. ACO parking deck drains and channels reliably handle large volumes of rainwater, and are rugged enough to cope with the harsh conditions associated with rainwater.
Gravity drainage systems are recommended for parking decks with vehicular traffic because of the accumulation of dirt on the surfaces. Gravity drainage systems have wider pipes than syphonic drainage systems and are therefore less likely to become blocked. ACO Building Services therefore has no syphonic drainage systems specially for parking deck drains.
