    • Adequate depth of cover materials and slope to drain by gravity to the city sewer system per SDFDM Section 4.4

  • The line has been cleaned and its condition verified with a closed-circuit video or other city-approved inspection method within the previous six months and Environmental Services has given the line a grade of 2 or better according to the bureau System Plan
  • A pipe survey and as-built drawings are not required. Environmental Services will provide them as part of the permitting process 

Adoption Requirements

  • Line is at least six inches in diameter
  • Line has a clean-out upstream of the portion to be adopted
  • Environmental Services has graded the line as 4 or better acccording to the scale in Section 7.A.7 of the November 2012 Nonconforming Sewer Conversion Rules 
  • All property owners served by the private line must sign and submit to the city a transfer of ownership
  • The property owners pays a city branch charge
  • All property owners connected to the line make an official adoption request that includes the following:
    • Documentation of the physical location of the sewer, either electronically or physically, and its route from the properties being served to the existing public sewer connection
    • Documentation that the sewer is clean and that the pipe's condition has been verified with closed-circuit video or other city-approved inspection method within the previous six months

Environmental Services staff will evaluate the request and make one of four decisions:

  1. The city will adopt the line as-is
  2. The line needs repair to meet the eligibility criteria in Section 7.B.1  of the November 2012 Nonconforming Sewer Conversion Rules
  3. The properties served by the sewer meet the Systems Improvement Decision Criteria in Section 6 of the November 2012 Nonconforming Sewer Conversion Rules and the city already has plans (subject to change) to provide a new public sewer adjacent to the property within two years based on current budget priorities
  4. The line does not meet the criteria and the city will not accept or adopt the line
