6. Cold water network

The layout of a network depends on the construction (routes, holes, supports, etc.), but other trades (electricians, carpenters, masons, etc.) must also be taken into account. For any project of any significance, it's a good idea to look for possible routes and to assign each trade the place it needs to occupy. Several criteria need to be taken into account: choice of pipe material, nature and temperature of the fluid, pipe layout, assembly method, installation (buried or embedded pipes), supports and hydraulic constraints (pressure drops, flow rates, pressures).
