(ii) Excavation: A hole is excavated in the ground at the designated location to accommodate the manhole structure. The depth of the excavation will depend on the required access and the depth of the utility lines or sewer system being accessed.

4. Perforated Grates Often made from various materials, perforated grates are designed with holes to enhance water drainage while still catching debris. They are frequently used in combination with drainage systems for optimal performance.

One of the primary roles of ground-embedded bollards is to improve safety in urban settings. By controlling vehicular access to pedestrian areas, parks, and busy shopping districts, bollards prevent accidental or intentional vehicle incursions. This is particularly crucial in high-traffic areas where pedestrians are present, reducing the risk of accidents and potential fatalities. By physically delineating space, bollards create a clear visual barrier that alerts drivers to pedestrian zones, thus contributing to a safer environment for all users.

(vi) Installation of the Cover: Once the desired height of the manhole is reached, a cover or top section is installed. This cover is usually made of cast iron or concrete and is designed to support the weight of vehicles or pedestrians passing over it.

Environmental Impact

Drain covers are often taken for granted in urban infrastructure. They serve a critical role in maintaining safety and sanitation in our cities and towns. However, when a drain cover becomes broken or damaged, it can lead to serious consequences that impact not only public safety but also environmental health.
