In water tank design, a footrest is a safety feature that provides support and stability for workers performing maintenance or inspections inside the tank.
Typically constructed from metal rungs or ledges, footrests are integrated into internal ladders or attached to the inner walls at regular intervals, allowing workers to pause, rest, or safely reposition themselves while climbing.
These footrests enhance safety by reducing fatigue during vertical movement and offering a secure foothold in confined or slippery environments.
Their inclusion is crucial in ensuring compliance with safety standards, especially in large or deep tanks requiring periodic access for cleaning, repairs, or inspections.

A footrest detail in construction is typically described with precise dimensions, materials, and placement instructions. Here’s a written description you can use for drafting:
Material:
- Use mild steel (MS) pipe or galvanized iron (GI) pipe with a diameter of 25–40 mm for durability and corrosion resistance.
- Alternatively, reinforced concrete (RC) ledges or cast iron brackets may be used in specialized environments like water tanks.
Placement:
- Install the footrest at intervals of 300 mm (12 inches) vertically along the access ladder or wall.
- The horizontal projection from the wall should be 150–200 mm (6–8 inches) to provide sufficient footing.
Fixing Method:
- Embed the footrest into the concrete wall during casting, ensuring a minimum embedment depth of 100 mm (4 inches).
- For retrofitting, use chemical anchors or expansion bolts with anchor plates welded to the footrest bar.
Spacing:
- Horizontal spacing between footrests (if multiple) should be around 300 mm (12 inches), matching ergonomic standards for safe climbing.
Finish:
- Apply a non-slip coating or texture on the surface of the footrest for safety, especially in wet environments.
- Provide corrosion-resistant paint or hot-dip galvanizing in environments prone to moisture or chemical exposure.
