Concrete Pipe

Concrete pipes are fundamental components in water and wastewater treatment plants. They are used for conveying treated water and raw, semi-treated, or treated wastewater within or between different treatment stages or to the final discharge point. Concrete pipes are favored due to their durability, strength, and resistance to corrosion and abrasion. 

​

They function simply as conduits, relying on gravity or pump pressure to move fluids.

• Conveying raw sewage from the collection system to the treatment plant
• Interconnecting different treatment units, for example, from primary clarifiers to aeration basins
• Discharge lines, carrying treated wastewater to outfalls
• Stormwater conveyance in combined sewer systems

• Routine operation tasks: Regular inspections for leaks, blockages, or surface deterioration.
• Typical maintenance procedures: Clearing blockages, repairing leaks, replacing damaged sections.
• Important safety considerations: Proper handling to avoid injury due to the heavy weight, ensuring secure installation to prevent pipe movement or collapse.

• Concrete Body: Provides structural integrity and durability, typically made of reinforced concrete to withstand internal and external loads.
• Pipe Joint: Ensures leak-proof connection between pipe sections. May be rubber-gasketed or mortared.
• Reinforcing Steel: Provides additional strength, especially for large diameter or high-pressure applications.
• Protective Linings: Applied to the internal surface to protect against corrosion or abrasive wear in harsh sewage conditions.

• Flow rate (L/s or gpm)
• Pressure (psi)
• Soil loads (kPa or psf)
• Pipe diameter based on the peak flow rate
• Wall thickness and reinforcement are determined by internal and external loads.

• Ductile Iron Pipe: More expensive but stronger and lighter, preferred in high-pressure applications.
• PVC Pipe: Cheaper and lighter, but less durable and can't resist heavy loads, suitable for small-diameter, low-pressure applications.
• HDPE Pipe: Flexible and corrosion-resistant, can be a good choice for challenging soil conditions or trenchless installations.
