If you have a drain in your parking lot, it is your responsibility to maintain the drain. It should be cleaned by a professional drain cleaning company at least every two years or when the drain catch looks like it is about half way full. Proper maintenance is required in order to prevent flooding and property damage.
Some people refer to a parking lot drain as a catch basin, storm drain, or French drain. There are two different primary styles of parking lot drains. A catch basin is designed to catch large debris and prevent it from entering the local sewer system, while allowing water to pass through. A french drain uses rocks placed in a trench to filter out larger objects and direct water to the local sewer system. A storm drain generally refers to any drain that carries water away from roads and parking lots.
Regardless of what type of drain you having, it needs to be cleaned every two years or when it appears to be half full. To correctly clean out a storm drain, a professional vacuum truck is used. It uses a combination of high pressure water and high power suction to remove any wet built up debris within the drainage lines. There can be debris built up within the drainage system that is not visible from just looking at the drain, which is why is important to call in professionals to clean any drains you have in your parking lot.
It is important to clean out any and all drains in your parking lot at least every two years for a variety of reasons. First, drainage systems are expensive to install. Proper cleaning will ensure that your drainage system lasts for years to come. Next, when drains are not cleaned out regularly, this can lead to parking lot floods.

Hiring a professional company at least every two years to come out and clean out your drainage system. This will prolong the life of your drainage system. Proper maintenance will also prevent your parking lot from flooding and creating property damage.
