Constantly building? To every house? No, most houses are already built, with the supply lines installed decades ago. (Thus amortizing the cost over those decades.) Much more disruptive & expensive to dig up roads & landscaping to retrofit.

One could assume the mission critical gas pipe would be omitted...
Still used for cooking.

Another more radical thought, why not just use the existing pipes, the powerplant complex makes enough heat to heat 500,000 homes, more than are even in the area, why not just run all municipal water as hot through existing lines, the heat sync affect would eventually allow the water to be hot in most areas and to get cold water you would need a heat sync.
Because in most cases the powerplants are not located anywhere near the water sources? Because the energy & equipment needed to cool water would wipe out most of the hypothetical savings?
