Areas Served by the Regional System Current wastewater treatment services are provided to the City by Environmental Services. All wastewater generated within the City is conveyed through Met Council Interceptors 8567, 8352A, 7113 and 7113A. All flow is treated at the Blue Lake Water Resource Recovery Facility in Shakopee. Regional Inflow and Infiltration Program The Met Council is continuing implementation of its inflow and infiltration (1/1) reduction program and will continue to establish 1/1 goals for all communities discharging wastewater to the regional wastewater system. Communities that have excessive 1/1 in their sanitary sewer systems will be required to eliminate the excessive 1/1. Those communities will be required to submit a work plan that details work activities to identify and eliminate 1/1 sources from both municipal and private sources. The Met Council will not design future regional sanitary sewer improvements or water resource recovery facilities to handle peak hourly flows in excess of the allowable rate for your community. Increases in service may be limited in communities that do not demonstrate progress in reducing excess 1/1. Two grant programs are currently available for communities with excessive 1/1 in their sanitary sewer systems: The Municipal Inflow and Infiltration Grant Program and the Private Property Inflow and Infiltration Grant Program. It is recommended that communities review these programs and determine if participation fits into their 1/1 work plan. The Municipal Inflow and Infiltration Grant Program is based on annual legislative action and funding amount and availability may vary year to year. Areas Served by Local Wastewater Treatment System The requirements of this element do not apply because Orono does not have a local wastewater treatment system. Areas Served by Private Communal Treatment Systems and/or Subsurface Sewage Treatment Systems The Met Council's position is that private communal wastewater treatment systems should only be permitted in areas not programmed for regional sewer service in the foreseeable future and they are provided for in a community's comprehensive plan. The community is responsible for permitting all private communal or cluster wastewater treatment systems consistent with current Minnesota Pollution Control Agency standards (Minnesota Rules Chapter 7080-7083). The Met Council will not provide financial support to assist communities if these systems fail. Communities with individual subsurface sewage treatment systems (SSTS), commonly known as septic systems, must adopt a management program consistent with current Minnesota Pollution Control Agency regulations (Minnesota Rules Chapter 7080-7083). A description of the management plan and current SSTS ordinance must be included in the community's comprehensive sewer plan. 2025 SYSTEM STATEMENT WATER RESOURCES 24 27
