Maintenance Feature Class

You can administer maintenance work for all wastewater network features, except the intermediate points. The Maintenance feature class stores information about completed maintenance work. The feature class uses the maintenance type domain table. In the basic wastewater application, this domain table only contains general maintenance types. It can easily be enhanced to meet the requirements of the customized wastewater application.
