Having storm drains in the parking lot of your business is essential. With any large area of pavement, you will get a greater amount of water flowing, and if you have a low spot anywhere, that is where the water will collect, possibly making your parking lot unusable. This is why the placement of a storm drain is essential, but many times you will have no control over where it ends up. If you find that it is in a location that doesn’t make sense, moving it could cost thousands of dollars.
Checking that your storm drains are working properly during the year is a good idea, especially since you don’t want to realize that it isn’t working once the storm has started. It is possible that your storm drains gets plugged up, and that could lead to water damage in nearby buildings. If you have an annual property maintenance schedule, make sure that pouring water down the storm drains is one of the items on it.
