Sewer System Connection Charges

Purchasing a Tap
Regarding system connection charges, an applicant may not purchase their tap until the Engineering Department has issued a Tap Sale Release Form for your property or project.

Calculating the Fee
Number of Single Family Equivalents (SFEs) x Connection Charge per SFE + Administrative Fee per Tap = Southgate Cost to Connect to Sewer System

In no case shall the number of sewer SFEs purchased for your development be less than the equivalent water SFEs per the domestic water tap size purchased for the same development (e.g. if a 1" domestic water tap is serving your property, you must purchase a minimum of 2 sewer SFEs).  Water SFEs per domestic water tap size can be viewed under Water System Connection Charges.

Calculating SFEs


SFEs may be estimated with the Sewer SFE Calculation Worksheet.  The applicant may submit a variance request for an alternative method of calculating SFEs, based on historical water consumption of a similar product or based on fixture count.  The variance request must include existing water consumption bills or stamped, engineering calculations of projected average daily flow based on fixtures installed. If the variance request is approved, the projected average daily flow may be used by Southgate to calculate the sewer system connection charge for your property.  Variance requests will only be considered for active projects/applicants, and not for pre-planning or due diligence phases.
