eMOR
Electronic monthly operating report
The electronic monthly operating report (eMOR) is an online tool for reporting monthly pumpage, chemical addition, treatment at public water systems and other information as required by DNR. Monthly reporting is a requirement for all municipal water systems and some other qualifying water system types, per NR 810.07, Wisconsin Administrative Code [exit DNR]. Only a certified operator for the water system can submit the report. However, staff associated with the system who are not certified operators can enter data with the permission of the certified operator. Monthly reports are due within 10 days from the end of the month for which the data is reported. For example, data from July must be submitted by the 10th day of August.
Access to eMOR
Users will need a WAMS ID and to request access to the report through the DNR Switchboard. Staff who are not certified operators also need to complete an additional step of obtaining data entry access permission from the certified operator. After the switchboard registration is submitted, the registrant will receive an email with a PDF signature page for the certified operator to sign for approval.
