Less than a dozen of these systems remain within the City limits. The City's code does not allow subdivision or development without connection to City sewer and water (Chapter 153.17). City ordinance also does not allow existing ISTS to be replaced as long as connection to City sewer is feasible. The City also plans to have all residents connected to city water and sewer services by 2040. For the small number of existing ISTS, the City employs Anoka County's services for required inspections. If for some reason, a new ISTS would be the only available form of sewering an existing parcel, the City would ensure that it was designed and constructed in accordance with MPCA rule 7080. This is, however, highly unlikely. hlflo,vf iwd hlhlh-i0l()�l Met Council has consistently concluded that Centerville's flows during wet weather events do not show significant signs of Inflow or Infiltration (1/1). This is likely due to the fact that most of the city's sewer system (both public and private) was constructed, post 1970, from largely gasketed, PVC pipe. Ordinance #XX (see Appendix XX) prohibits sump pumps, foundation drains and rain leaders from being connected to, and/or discharged into, the sanitary sewer. The city's programs and strategies to prevent 1/1 consist of links on the City's website to VI prevention information for homeowners, information placed in the City's newsletter, on the City's website or social media feeds and brochures in the front lobby of city hall. Again, because the City has such minimal 1/1 issues, the City's VI prevention or mitigation program may be smaller than others, but is appropriate, relative to the size of the problem. Regularly, portions of the City's sewer are televised in a rotation ensuring all mains are televised every ten years. During these inspections, services exhibiting constant clear water flows are noted and investigated for possible illegal connections. Chapter 7 1 Page 3
