Concept Design for Water Supply System
1. Water demand
Defining correctly the water demand at the beginning is the most important and sensitive part of the design as it is at the base of all further steps.
The attached paper (pdf file) will help you to go through necessary steps according to your specific context and give you advises on which information to collect and how to collect it.

3. Water storage needs
Tanks are an essential component to balance the difference between the demand and the supply, but they have also other uses. Over sizing might be as bad as under sizing.
The attached paper (pdf file) will help you to understand the storage need for your system and the importance of a good manage

5. Pumping station and pipeline
1) Enter you system specs to find you pump or the opposite.
2) Calculate necessary throttling or speed reduction.
3) Check if the water surge might be a problem...

Draft version, surge analysis should be included
|
No tutorial yet available, but done according to the chapter on pumps of the Part 1

6. Distribution networks
|
You can already use the Excel tool with its short tutorial. You will first have to define the simultaneous factor, then you can use a table similar to Gravity Pipeline, but for distribution with intermittent demand. |
