A drill rig having a longitudinal drilling axis, a front portion, and a rear portion can comprise a feedframe aligned with the longitudinal drilling axis, a first head assembly coupled to the feedframe and configured to rotate a drill string, and a rod holder proximate the front portion of the drill rig. A second head assembly can be movable on the feedframe along the longitudinal axis and can include a powered water swivel assembly comprising a spindle having an interior bore a drill rod connector at a first end of the spindle, a motor that is configured to rotate the spindle, a clutch configured to disengage the motor from the spindle, a gearbox that couples the motor to the spindle, and a water swivel that is configured to provide drilling fluid to the interior bore of the spindle.

Diverter assemblies having a housing, first and second rams, first and second actuators for moving the rams, and first and second sealing members respectively coupled to the first and second rams. The housing defines openings surrounding a drilling axis and configured to receive a pipe in a drilling position, and the rams are moveable relative to a longitudinal axis of the housing that is substantially perpendicular to the drilling axis. The first and second sealing members engage the pipe, and projections within the housing cooperate with the sealing members to form a seal around the pipe and the openings of the housing. Systems and methods of using the diverter assemblies are also disclosed.
