​I am working on a municipal project that includes reconstruction and/or relocation of sanitary sewer trunklines serving several neighborhoods in a hilly area.  All of the existing residences currently connect to the existing trunklines via gravity sewer laterals.  Proposed collection system upgrades will require a number of existing residences to convert from gravity laterals to on-site grinder pumps to connect to the new trunklines.  I have found several examples of municipal ordinances with requirements applicable to private on-site grinder pumps for new sewer service connections for new development.  However, I am interested in seeing any examples of municipal ordinances or policies that have been implemented to address existing customers that will be required to convert their existing sewer service connection from a gravity lateral to a private on-site grinder pump installation.  Any input would be greatly appreciated.
