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 Equivalent Residential Units(ERUs) will be calculated based on anticipated flow into the sanitary sewer system. This figure will be multiplied by Connection Charge per ERU plus Administrative Fee per Tap equals Southgate Cost to Connect to Sewer System.
In no case shall the number of sewer ERUs purchased for your development be less than the equivalent water ERUs 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 ERUs). Water ERUs per domestic water tap size can be viewed under Water System Connection Charges.

Calculating ERUs
ERUs may be estimated with the Sewer ERU Calculation Worksheet (PDF). The applicant may submit a variance request for an alternative method of calculating ERUs, 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.
If actual sewer discharge exceeds a property's allocated Equivalent Residential Units (ERUs), Southgate may require the purchase of additional Sewer Tap Sales to cover the deficit.
