The utility model belongs to the technical field of water supply engineering, relates to a secondary pressurized water supply manner when the tap water pipe network pressure cannot meet the building water supply pressure requirements, in particular to an energy-saving water supply negative-pressure-free pipeline. The energy-saving water supply negative-pressure-free pipeline comprises a tap water pipe meshwork pipeline, a booster pump and a high-pressure water supply pipe and is characterized in that a siphon pipe is arranged on the tap water pipe meshwork pipeline at the inlet of the booster pump, and a horizontal automatic exhaust valve is installed at the top part of the siphon pipe. According to the utility model, the structure of the water outflow end of the booster pump in the prior art is not changed, an effect of a negative-pressure-free steady-flow water supply set is achieved, and the negative pressure is not stressed to a primary pipe network; and the energy-saving water supply negative-pressure-fr
