Functions of storm drain include draining excess water (rain or storm water) and ground water from pavement, streets and carparks into rivers and streams to prevent flooding.
Although storm drains do a amazing job of draining excess water from the urban areas, the inlets are essentially openings where left uncovered could be a hazard to pedestrians. Left uncovered, rubbish will enter the storm drains and cause choking which can eventually trigger flooding.
In order to guarantee storm drains serve their purposes while minimizing the risks posed to pedestrians and to prevent choking of the drains, drain covers (gratings) are used to cover the inlets (openings) of the storm drains to achieve the two purposes.
