Engineering Properties and Economic Feasibility Evaluation of Eco-Friendly Rainwater Detention System with Red Clay Water-Permeable Block Body
Round 1
Reviewer 1 Report
This article presents studies of the characteristics of eco-friendly rainwater detention system that can prevent floods and secure groundwater levels during intensive rainfall.
Solutions to natural disasters such as flood prevention are important scientific issues.
Therefore, this manuscript is worth publishing.
However, this paper to reach an acceptable level that suits this journal, the minor revisions are needed.
- Please, enrich the state-of-the-art part (Introduction) with the additional references - in the reference list, you have 20 referencesin total.
- Please, make sure that the axial form in each figure is clearly filled out. Figure 5. And Figure 6. are written in units only.
- Is there any reason to why "Because the eco-friendly rainwater detention system is a secondary concrete product, its lifetime is set to 80 years."?
- Please, abstract need to be rewritten to report about the main and new findings obtained in this paper briefly.
- Please, get proofreading or confirmation of the contents of this paper through native English speakers or proofreading experts.

Reviewer 2 Report
1. The authors describe the water drainage system, but its diagram is not shown; as a result, it is difficult to figure out which element of this system is being modified. (lines 75-80), the purpose of modifying the element is not clear. What loading conditions is this sample under?
2. In chapter 2.3.2. Porosity, the authors should give a description of the resulting structure of the porous element; in the figure, photographs of the grain fraction are required. Are there any modifications of the porosity and strength of the material of this structure with different variations of the selected components of the starting material
3. Chapter 2.4.1 lacks a visual description of the structure of the strength estimation algorithms
4. In chapter 2.4.2 at the beginning there is no simple diagram of the element loading.
5. Because the structure has some internal dimensional parameters in the form of wall thickness and holes, they must be given in the form of a drawing
6. The properties of the material used for the calculation are not given, how do they agree with the experimental ones? What finite elements were used for the calculation?
7. What are the safety factors in the structure?
8. Figures 2, 4, 7 do not show the individual names of the elements. Photo only shown. If a press of a certain brand is used, then this must be indicated in the text.
9. Chapter 3.4 shows the calculation. How can the authors explain the maximum stresses on the lid? What is their level when compared with other stressed structural elements? What happens in the area of ​​stress concentration points in the corners of the structure? Has there been any design optimization for wall thickness, for example?
10.Figure 8 a lacks a description of the red callout
