RCC Precast Tank Installation Guidelines

Do's and Don'ts for RCC Precast Tank Installation

Use these simple guidelines to help clients and contractors handle Togreen Infra tanks safely and correctly.

Do's

  • Do clear all debris, loose soil, and obstacles from the excavation area before starting work.
  • Do provide safe access for excavators, concrete trucks, and lifting equipment.
  • Do clearly mark the tank location, setbacks, and working clearances as per approved drawings.
  • Do ensure the pit has straight sides, correct dimensions, and a level base before lowering the tank.
  • Do compact the base layer properly and remove stones or sharp objects that could damage the tank.
  • Do keep the excavated soil at a safe distance from the edge of the pit to avoid collapse.
  • Do keep the pit dry; pump out any collected water before placing the tank.
  • Do position the tank so that manholes, riser pipes, and connections are easily accessible for maintenance.
  • Do use trained and experienced operators for cranes, loaders, and other lifting equipment.
  • Do provide safety barricades and warning signage around the open excavation to prevent unauthorized entry.

Don'ts

  • Don't over‑excavate beyond the required length, breadth, and depth unless instructed by the engineer.
  • Don't commence excavation when heavy rain is expected, as it can cause pit collapse or flooding.
  • Don't leave sharp projections, boulders, or construction waste at the base or sides of the pit.
  • Don't allow vehicles or heavy equipment to move too close to the unsupported edges of the excavation.
  • Don't lower or lift the tank using improper hooks, chains, or slings that could damage the structure.
  • Don't backfill with large rocks or uncompacted soil that may create point loads on the tank walls.
  • Don't cover or block access covers, vents, or inspection points after landscaping or paving.
