Abstract: A sprinkler system for a temporary chute used for disposal of construction materials during a construction or renovation project. The sprinkler system is releasably engaged with the temporary chute and is used to control dust within the chute, wash down the chute, and extinguish fires. A housing of the sprinkler system is releasably engaged with an intake hopper of the chute, placing an interior chamber of the housing in fluid communication with the chutes' tunnel. First and second sprinkler heads are located within the interior chamber. The first sprinkler head is temperature sensitive and automatically actuated when a threshold temperature is crossed. The second sprinkler head is manually activated by an operator to spray liquid into the tunnel to control dust or wash the interior surfaces of the chute. The sprinkler system and temporary chute are disengaged from the building once the construction or renovation project is completed.
