What is a retention pond?

Retention pond is a basin that is designed to catch drain water from areas with higher altitude. Retention ponds are used to prevent or minimize floods during a period of high water. These river basins are usually designed with an overflow pipe to control water levels and evenly distract water. They rarely occupy many soil and average less than 1 hectare (4046.86 m ^{2 ) in total. Most ponds are built in areas that have the surrounding soil capable of holding high water during rainy periods. Allowing an excess of the surrounding soil is considered necessary for proper function and safety.}

The development of the retention pond will be used to remove pollutants and reduce floods. The ponds can serve as a temporary or permanent runoff river basin and is very common to find them in areas that pass through a significant amount of construction. This is due to the fact that large areas consisting of Impermus do not absorb water.

permanent rYbants are often built in lower ground areas that tend to accumulate excessive water. Retention ponds help to remove pollutants because garbage and remains usually hit the pond after heavy rains. The washbasins also capture the outflow containing oil, fertilizers, sediments, bacteria and other harmful substances that can have a negative impact on the overall water quality.

When pollutants enter the pond during heavy rain, the basin slows down the movement of water. Stagnant water allows heavier contaminants such as solids or metals, sink to the bottom of the pond and eventually become the sediments of the bottom layer. The detained water naturally filters contaminants and returns clean water to the surrounding streams or wetlands.

Retention pond located in a residential area may be a security concerns and some mucking of preventive measure should be takeno. Banks of retention ponds are usually built from shallow shores and then fall sharply after about 2 feet (0.5 meters) of shallow water. Shallow shores are exerted as safety measures to prevent drowning, but children should still be kept far from the pond and the surrounding areas. These areas are also potentially dangerous due to the level of contaminants that accumulate in stagnant water.

In order to maintain a safe and efficient retention pond, it must be properly maintained. Adding a waterfall or aeration can help prevent mosquitoes and other pests in excessive breeding around the pond. The pest control specialist can also alleviate the problems of insects by adding natural larvacide to the pond. Retrigction of algae is another potential problem and may need to contact An Aquatic Management Specialist which PoskyIt tires the right bacteria and microbes for the pond.
