What is a curb drain?
A curb drain is a part of a street that has been concreted over and can be lowered from the street above to allow water to flow freely away from the roadway, usually hidden under a layer of decorative flagstones or sidewalk.
A weather-enduring concrete or steel curb is placed in front of the drain to slow the flow of water into the drain and maintain a transition away from the roadway.
The curb may also include a water retaining barrier to slow the flow of water into the curb, and prevent the roadway from flooding.
Can I drill a hole in my curb?
Curb drains are to be used only when there is excess water, such as from snow melting.
A hammer drill with a 3 and 1/8 inch bit can be used to drill a hole through the curb, a 4 inch downspout can be attached to this hole to drain the water away.
