Layout design support device, layout design support method, and non-transitory computer-readable recording medium

A layout design support method of supporting design of a layout of underground facilities buried in underground of a plant, the layout design support method comprising:

• acquiring ground layout information relating to a layout of ground facilities arranged on ground of the plant, and design condition information relating to design of the underground facilities;
• generating, based on the ground layout information and the design condition information, positions of a plurality of water collection points into which a liquid is collected from the ground of the plant, and a first piping route along which piping that discharges, from the plant, the liquid collected into the plurality of water collection points is buried in the underground of the plant;
• and
• outputting underground layout information indicating the positions of the plurality of water collection points and the first piping route.

A non-transitory computer readable storage medium storing a layout design support program for supporting design of a layout of underground facilities buried in underground of a plant, the layout design support program causing a computer to execute processing of:

• acquiring ground layout information relating to a layout of ground facilities arranged on ground of the plant, and design condition information relating to design of the underground facilities;
• generating, based on the ground layout information and the design condition information, positions of a plurality of water collection points into which a liquid is collected from the ground of the plant, and a first piping route along which piping that discharges, from the plant, the liquid collected into the plurality of water collection points is buried in the underground of the plant;
• and
• outputting underground layout information indicating the positions of the plurality of water collection points and the first piping route.
