Less than a dozen of these systems remain within the City limits. The City's code does not <br /> allow subdivision or development without connection to City sewer and water (Chapter 153.17). <br /> City ordinance also does not allow existing ISTS to be replaced as long as connection to City <br /> sewer is feasible. The City also plans to have all residents connected to city water and sewer <br /> services by 2040. <br /> For the small number of existing ISTS, the City employs Anoka County's services for required <br /> inspections. If for some reason, a new ISTS would be the only available form of sewering an <br /> existing parcel, the City would ensure that it was designed and constructed in accordance with <br /> MPCA rule 7080. This is, however, highly unlikely. <br /> hlflo,vf iwd hlhlh-ilh()�l <br /> Met Council has consistently concluded that Centerville's flows during wet weather events do not <br /> show significant signs of Inflow or Infiltration (1/1). This is likely due to the fact that most of the city's <br /> sewer system (both public and private) was constructed, post 1970, from largely gasketed, PVC <br /> pipe. Ordinance #XX (see Appendix XX) prohibits sump pumps, foundation drains and rain leaders <br /> from being connected to, and/or discharged into, the sanitary sewer. The city's programs and <br /> strategies to prevent VI consist of links on the City's website to VI prevention information for <br /> homeowners, information placed in the City's newsletter, on the City's website or social media <br /> feeds and brochures in the front lobby of city hall. Again, because the City has such minimal VI <br /> issues, the City's VI prevention or mitigation program may be smaller than others, but is <br /> appropriate, relative to the size of the problem. <br /> Regularly, portions of the City's sewer are televised in a rotation ensuring all mains are televised <br /> every ten years. During these inspections, services exhibiting constant clear water flows are noted <br /> and investigated for possible illegal connections. <br /> Chapter 7 1 Page 3 <br /> 124 <br />
