What is the minimum concrete cover required over a pipe carrying rainwater located under a sidewalk?

The minimum concrete cover required over a pipe carrying rainwater located under a sidewalk is generally specified as 2 inches. This requirement ensures adequate protection for the pipe from potential damage due to traffic loads and the weight of the concrete above. Sufficient cover also provides insulation to the pipe, reducing the risk of freezing temperatures affecting its integrity and functionality. It is important for the durability and longevity of both the concrete structure and the underground pipe system to maintain this minimum distance. Maintaining the specified concrete cover helps in preventing settling or cracking of the sidewalk and also meets code regulations aimed at ensuring public safety and infrastructure reliability.
