What is a storm drain grate?
Storm grates are usually found along the curb on residential streets, which helps drain rainwater runoff from storms. A storm grate is a lined metal opening usually along a curb on residential streets in cities, that is a pipe inlet for rainwater runoff from storms.
Can cats get out of storm drains?
Just a reminder for everyone who takes care of feral cats in urban and suburban areas: cats will sometimes take refuge from storms in sewers.
What are storm drain laterals?
A storm sewer service lateral is the pipe that connects a home’s or business’s downspouts, foundation drains (footing tile), sump pump discharge, and/or yard area drains to the City’s storm sewer system. There are fewer homes and businesses that have storm sewer service laterals than sanitary sewer service laterals.
What is the diameter of a storm drain?
Pipe flow capacity depends on the roughness coefficient, which is a function of pipe material and manufacturing method. Fortunately, most storm sewer pipes are 24-inch-diameter or less and studies have shown that most common schedule pipe materials of this size range have a similar roughness coefficient.
What are storm drains made of?
Storm drains in streets and parking areas must be strong enough to support the weight of vehicles, and are often made of cast iron or reinforced concrete.
How do I design a storm drain system?
The proper design of any storm drainage system requires accumulation of basic data, familiarity with the project site, and a basic understanding of the hydrologic and hydraulic principles and drainage policy associated with that design. The development of a storm drain design requires a trial and error approach:
Why do you need a storm drain cover?
1. Storm drain covers prevent environmental contamination The sole purpose of a drain cover is to prevent environmental contamination. You have to realize that any chemicals or hazardous materials which travel down the drain end up somewhere — usually in the closest body of water.
What makes an acceptable storm drainage design?
These conditions require sound and consistent engineering principles and the use of all available data to achieve an acceptable drainage design. Although the design of a storm drain system entails many conventional procedures, the design also requires engineering judgment.
What is the purpose of stormwater drainage?
The objective of urban storm drainage is to optimize safe passage of vehicle traffic by collecting stormwater from the roadway, and to convey it safely to an adequate receiving body without undue risk to pedestrian traffic or contributing to damage of adjacent private properties during the design storm event.
