Conkles Hollow is a gem in the Ohio State Parks system. This park has outstanding natural features, making it a popular location for a variety of recreational activities. Prior to our work at the park, the only sanitary facilities provided was plastic portable toilets. This was unacceptable to both the visitors and the park. Ohio State Parks always felt the setting and popularity of this location merited high capacity flush restrooms but the site was without power, water, or septic utilities. Green Flush installed multi-stall flush restrooms at Conkles Hollow. Each of these restrooms have three stalls for women and 2 stalls plus a urinal for men. They are equipped with solar power and propane heat for off-season use.
