Settling basins are ponds constructed for the purpose of removing entrained solids by sedimentation. Clarifiers are tanks built with mechanical means for continuous removal of solids being deposited by sedimentation.

Ponds for Entrained Solids Removal
When addressing the removal of entrained solids from water, the most effective solution is the use of settling basins. Here's a detailed explanation of why these structures are essential in civil engineering:
Definition of Settling Basins
- Settling basins are specifically designed ponds that allow solids suspended in water to settle out due to gravity.
- They are crucial in water treatment processes, particularly in the treatment of wastewater and stormwater.
Functionality
- In a settling basin, water flows into the basin, where the velocity decreases, enabling particles to settle to the bottom.
- The settled solids, also known as sludge, can then be removed periodically for further treatment or disposal.
Advantages of Settling Basins
- Effective Solids Removal: They significantly reduce the concentration of suspended solids, improving water quality.
- Cost-Effective: They require less mechanical equipment compared to other treatment methods, which can reduce operational costs.
- Simplicity: The design and operation of settling basins are straightforward, making them easy to maintain.
Comparison with Other Options
- Clarifiers: While clarifiers also remove solids, they are typically more complex systems that involve mechanical components.
- Eco-ponds: These are designed for ecological purposes rather than just for solid removal.
- Ditches: Primarily used for drainage, they are not specifically designed for settling solids.
In summary, settling basins are the best choice for effectively removing entrained solids from water due to their simplicity, cost-effectiveness, and efficiency in promoting sedimentation.
