Also contact DPW regarding sewer use (tapping in), road opening (curb cuts), hauling scavenger waste/wastewater (cesspool), dumpsters placed on County roads, treated water permit, industrial waste discharge into County lines and/or holding areas, and to facilitate the building permit process on County roads.
