Class Code: 7580
Per NCCI's Scopes Code Description:
This classification covers all operations of a sewage disposal plant that can be operated by a municipal board or commission or a private company. The plant can dispose of sewage by a number of methods, the most common of which are plain sedimentation, chemical coagulation, biological processes and various combinations of these three. These processes kill bacteria and speed up decomposition so that raw sewage is not dumped into waterways or incinerated. The extension of pipelines is contemplated by Code 7580 as well as repair and maintenance on same.
