Stormwater pollution is both a public health and environmental issue. Storm drains are designed with grids that prevent large debris from entering the sewer system. The bars, however, are wide enough to let water pass through, and a majority of objects may fall in including trash and animal waste that is left on the ground. This carries harmful disease-spreading bacteria that put you and your family at risk. Stormwater pits and drains can also become clogged with debris over time, such as sticks, leaves, litter and lawn mower clippings among others. Here are some effects of clogged stormwater drains on the environment and your health, plus tips for keeping stormwater pits and drains clean.
Effects of clogged stormwater drains
When drains get clogged, water ponds develop leading to flooding in homes, streets and intersections. This can cause inconvenience to the travelling public and also destruction of property at home. A majority of people believe that oils and wastes, among other debris they dump in the stormwater drains go to the waste water treatment plant. Contrary to this, the water may flow into streams and rivers causing pollution and health risks. It is, therefore, necessary to monitor and keep these drains clean to avoid flooding, property damage and health risks.
Keeping the stormwater pits and drains clean
Do not wait until a storm has occurred to inspect your drains. The best time is before the storm. Monitor your drains all the time, but especially during the time the trees are shedding and in the spring after snow has melted. When raking leaves off the drain, do not remove the grate. Remove only the debris located on top of the grate. Water runs to the lowest points and, therefore, you should build sediment control fences on the lowest sides and fit gravel socks to the stormwater pits. The gravel socks act as filters, separating sediments, nutrients, heavy metals, and hydrocarbons from runoff. The gravel rocks are also able to sustain and handle runoff at higher flow rates while maintaining less flooding. Also, keep the litter in your site contained. Bins with lids should do the trick and should also be emptied regularly. After the storm, maintain the openings to your drains to remove any debris.
In a worst case scenario, where there is a clog that you cannot reach or unclog by yourself, for example, in your downpipes, seek a professional's help. The professional will clean the stormwater pit and drains and further set up maintenance schedules. Before hiring one, however, ensure they are qualified, and they hold insurance.
