O&M Service Provider Checklists
These Operation and Maintenance Checklists serve as the foundation for the CIDWT National O&M Service Provider Programand were developed in conjunction with industry stakeholders.  They are designed for use in Operation and Maintenance activities performed on decentralized wastewater treatment systems and describe the key items to be recorded during a maintenance visit.   These forms not only facilitate standardization of maintenance activities, they are also useful for designers who develop operation and maintenance criteria for systems and state, county, and local regulators who provide wastewater management oversight.  Use of these checklists should be accompanied by proper attribution of the source.
