Comparative Analysis of Reliability Indices and Hydraulic Measures for Water Distribution Network Performance Evaluation
Round 1
Reviewer 1 Report
The manuscript concerns the important issue of the comparative analysis of reliability indices and hydraulic measurements for water distribution network performance evaluation.
My comments are as follows:
How you define of the “resilience” in WDN and WDN reliability, as well as redundancy, robustness, and serviceability?
Line 330. The obtained calculation from the figure 4. Scatter plots of Scenario 1 (x-axis – reliability index; y-axis – hydraulic measurement) should be presented in the form of the appendix. This figure has low resolution.
Line 330. Add information in the figure 4 about correlation coefficients.
Line 348. Some statistics should be presented, while mentioning as a strong correlation with
349 Red2 and Rob2, which cannot be seen in other indices under Scenario 2, etc.
Why the point of 4.2. Multi Criteria Decision Analysis (MCDA) is not in the methodology section?
Provide equations for all proposed indices.
More in general, the whole framework is not clear to the reader, and I would suggest to add some figure presenting the framework of the whole research.

Reviewer 2 Report
A nice paper, well written with clear purpose, methodology and obtained results.
The reviewer would suggest to change the term 'measurements' with another word; thus, hydraulic 'measure' or, better, hydraulic 'indicator' might be more suited for the context (actually, the word 'measurements' resembles data obtained by field instrumentation, and not by calculation).

Reviewer 3 Report
I want to thank the authors for their work.
The article is well organized, clear and the results are well presented. The discussion and the conclusions are good.
The topic is interesting and find a good performance indicator for a WDN is always an open question. The work tries to answer to this question comparing different type of reliability indices.
I have only a correction to suggest.
When you use CMH please use m3/h

Round 2
Reviewer 1 Report
The manuscript deals with the crucial an very important issue concerning a framework for improving the reliability of water distribution systems and is worth to be published. The following answers should be referred to in the conclusions. Is this approach was consulted with water managers? What is the perspective of the future work?
