Common Drainage Problems

Unless you live in a region where it scarcely ever rains, drainage will be a concern in your community. Suitable drainage is the answer, however, getting there requires you to meet strict requirements throughout different parts of your community.

Standing water is more than just unattractive. It can also be a safety threat and cause damage to your community’s buildings and surrounding concrete work, and also potentially serve as a nesting area for mosquitos. Puddling and pooling are typically caused when communities substitute natural areas that absorb rainfall with built settings that don’t. Here are a few common issues and areas your community should be aware of so you can prevent water from going down the drain:

Open lawns
Sometimes lawns are built without the needed grading for water to flow into the storm water system. Generally, lawn areas ought to have a 1.5%–2% slope to assist in making this happen. If the design lets the storm water go into a drainage network, then this water should disperse within about 48 hours of the storm. For other areas, standing water tend to be gone within 24 hours. If your landscaped spaces aren’t meeting these standards, you might need to add a layer of topsoil to achieve the required grade.

Roads and drives
For the most part, roads should be built with at least a 5% slope leading to the nearest catch basin or other storm water drainage system. Driveways should be slightly steeper, built with a 2% slope. You can tell if your roads and drives are meeting the minimum standards if standing water dissipates within 24 hours of a storm. Alternatively, you can use the “coin test,” which states that no puddle on a road should be any deeper than the coin’s thickness.

Detention basins
Detention basins are intended to hold water before it can flow into a connecting storm water system at an adjacent property. The entire structure comprises an inlet system, the basin itself and a discharge outlet. The outlet structure is the area to be mindful of as its openings are typically small and easily clogged. Make sure you maintain this part of the system by clearing these openings on a regular basis. If your roads, drives and detention basins aren’t meeting these standards, consider connecting the downspouts from your buildings to an underground piping system that leads to a catch basin. If this isn’t an option, you can use what’s called an “infiltration system,” which allows water to be absorbed into the ground.

And if you have open area drainage problems, additional lawn inlets located in lower areas can help. Connecting these lawn inlets to your overall storm water management system will ensure optimal results.

Managing storm water is an ongoing challenge that requires both vigilance and continued maintenance. The result is an attractive community that’s safe for your residents and free from the erosion and damage that can be caused by standing water.
