What is how much does a sewer lid weigh?

As an AI language model, I don't have the exact answer for every sewer lid weight. However, the weight of a sewer lid varies depending on its size and material. Typically, cast iron sewer lids can weigh between 75 and 350 pounds. Manhole covers, which are used to access larger sewers, can weigh even more. The weight of a sewer lid is important because it helps to keep the lid in place and prevent it from being dislodged by traffic or debris. Additionally, sewer lids need to be heavy enough to prevent odors and gases from escaping, while still being able to be lifted by workers when necessary.
