Centerville 2040 Comprehensive Plan <br /> <br /> <br />ordinance and commence enforcement through compliance reminder letters. There are no <br />community (multi-unit) subsurface treatment systems in Centerville. If, for some reason, a new <br />SSTS would be the only available form of sewering an existing parcel, the City would ensure <br />that it was designed and constructed in accordance with MPCA Rule 7080. This is, however, <br />highly unlikely. Map 7-2 shows the location of existing SSTS within the City. Chapter 51, <br />Municipal and Public Utilities provides regulation over SSTS in the City. <br />I NFLOW AND I NFILTRATION <br />GENERAL <br /> <br />In February 2006, Metropolitan Council instituted its Infiltration/Inflow (I/I) Surcharge Program. <br />The fundamental policy statement summarizing this <br />not provide additional capacity within its interceptor system to serve excessive inflow and <br />communities that use its system. Communities that exceed this threshold are required to <br />eliminate this excess flow within a reasonable timeframe or pay a surcharge fee. Centerville has <br />not been identified by Metropolitan Council as a municipality with excessive I/I. The City does, <br />however, does take action to limit I/I and preserve capacity within its system. This program is <br />described further in the following sections. <br />SOURCES AND EXTENT OF I/I <br /> <br />Met Council has consistently concluded that Centerville's flows during wet weather events do <br />not show significant signs of Inflow or Infiltration (I/I). This is likely because most of the City's <br />sewer system (both public and private) was constructed, post-1970, from largely gasketed, PVC <br />pipe. <br />In 2018, the City received a letter from MCES stating that, during a large rain event, peak flows <br />spiked to over 80% of their prescribed I/I threshold. However, The City believes this spike was <br />caused by inflow to the system through a construction site in Lino Lakes, which had its manholes <br />exposed during the event. This Lino Lakes neighborhood is part of the Cit <br />community flow, so any inflow would come through the Centerville system. <br />The EPA Guide for Estimating Infiltration and Inflow (June 2014) was used to estimate the <br />from Metropolitan Council Environmental Services, for the period of 2015 to 2018. Monthly <br />average flows for the four-year period March to November (representative of a wet portion of <br /> <br /> Page 87 <br /> <br /> <br />
