Various drainage systems slow down the water surges associated with rainfall and minimise flooding before directing water to natural bodies of water or soil. Before construction of the drainage, a company offering civil engineering assistance should survey your area and recommend the ideal one. Here are the kinds of stormwater drainage systems that they might recommend:

Swales

These are systems shaped in a manner that allows seepage into natural water bodies or groundwater. Swales are open drainage systems that hold water after rainfall but remain dry in other seasons. They are aesthetically appealing and inexpensive to construct. However, they are ideally used in areas with a sloping gradient of less than 5%.

Retention Basins

These systems store surface runoff for about 72 hours. This runoff retention allows the water to seep into a pre-constructed and shallow aquifer. The engineer might recommend plantation of grass around the retention basin to sift sediments and stabilise the slope around it. With a retention basin, water does not flow into natural water bodies.

Wet Detention Systems

These are the standard option worldwide. The runoff in wet detention systems is gradually absorbed into the soil over an indefinite time. The system comprises a permanent pond constructed below it, which holds the water as it seeps into groundwater. You can raise aquatic plants along the wet detention system’s perimeter to sieve out sediments.

Rain comes with many benefits, but it should not wreak your locality. With the given drainage systems, your area free from water damage associated with surface runoff. Your choice will be determined by the rainfall amount in your area and available land.
