Mower County will have to spend extra money to ensure that runoff doesn’t form a large pool of ice on the roof of the new Mower County Jail and Justice Center next winter.

The Mower County Board of Commissioners approved a change order Tuesday to correct an engineering glitch that left a pipe from the building’s humidification system draining on the roof. The system puts humidity in the air through a mist during the winter. However, excess water was draining onto the roof. Since the system operates primarily during the winter, there’s concern that the ice could collect and damage the roof.

The change will cost an additional $9,540 for plumbing work, along with electrical and insulation work. The pipe will have to be insulated outside and will drain into the sewer.
