A wellhead container for a geothermal system includes a base configured to engage a bottom of a recess within a ground. The recess extends vertically from the bottom of the recess to a surface of the ground, the base includes at least one first opening, and the at least one first opening is configured to receive a drilling string. The wellhead container includes a top configured to support a load applied by a drilling machine to the wellhead container. The top includes second openings, and each second opening is configured to receive the drilling string. The wellhead container includes a sidewall extending along a vertical axis between the base and the top. The sidewall is configured to position an upper surface of the top substantially flush with the surface of the ground, and the sidewall is configured to transfer at least a portion of the load to the base.
