Rule 58.01.16 - WASTEWATER RULES
Section 58.01.16.520 - FACILITY AND DESIGN STANDARDS FOR MUNICIPAL WASTEWATER TREATMENT OR DISPOSAL FACILITIES: HANDLING AND TREATMENT OF SEPTAGE AT A WASTEWATER TREATMENT PLANT
Current through August 31, 2023
01. General. Septage disposal at a wastewater treatment plant is at the discretion of the owner of the wastewater treatment plant, unless other conditions apply. One method of septage disposal is the discharge to a municipal wastewater treatment plant. All plants require special design considerations prior to the acceptance of septage. Prior to acceptance of septage at a wastewater treatment plant, the plan for doing so must be addressed in the Facility Plan. (3-31-22)
02. Characteristics. Tables No. 1 and No. 2 (Tables 3-4 and 3-8 from the U.S. EPA Handbook entitled "Septage Treatment and Disposal" 1984, EPA-625/6-84-009) give a comparison of some of the common parameters for septage and municipal wastewater. These tables are located at the end of Appendix A-3 of the Recommended Standards for Wastewater Facilities. See Section 008 of these rules. (3-31-22)
03. Considerations. It is essential that an adequate engineering evaluation of the existing plant and the anticipated septage loading be conducted prior to receiving septage at the plant. The wastewater treatment plant owner shall be contacted to obtain the appropriate approvals prior to the acceptance of septage. For proposed plant expansion and upgrading, the Preliminary Engineering Report and Facility Plan shall include anticipated septage loading in addressing treatment plant sizing and process selection.
