Question

Into what four categories are drainage defects normally broken down?

1) Category 1, Category 2, Category 3, Category 4
2) Category A, Category B, Category C, Category D
3) Category I, Category II, Category III, Category IV
4) Category X, Category Y, Category Z, Category W

Answer 1

The four categories are drainage defects normally broken down are 3) Category I, Category II, Category III, Category IV

Step-by-step explanation:

Drainage defects are typically broken down into four categories: Category I, Category II, Category III, and Category IV. Category I refers to minor defects that do not significantly affect the overall drainage system. These defects may include small blockages or obstructions in the drainage pathways.

Category II represents moderate defects that can cause some disruption in the drainage system. These defects may include partial blockages or structural damage to the drainage infrastructure. Category III refers to major defects that severely impact the drainage system. These defects may involve complete blockages, collapsed pipes, or significant erosion of the drainage channels.

Category IV represents critical defects that completely disable the drainage system. These defects may include total blockages or failures in the drainage infrastructure, rendering it inoperable. Therefore the correct answer is 3) Category I, Category II, Category III, Category IV
