The Sanitary Sewer Trunk Charge (SSTC) is one source of revenue for the Sanitary Servicing Strategy Fund (SSSF). Upon receipt of an approved development permit or building permit, the successful applicant must pay applicable charges (see the list of current rates below).

All money collected is deposited into the SSSF and used to build new major sanitary trunk sewers under the approved Sanitary Servicing Strategy. The SSTC is levied when development permits are issued for development, redevelopment or renovations on the premises abutting an EPCOR Water Service Inc. or City right-of-way in which there is a sanitary or combined sewer.

B = Charges paid, or would have been paid had a sanitary sewer trunk charges been levied with respect to the existing development.

If A minus B results in zero or negative amount, no payment or refund is applicable.

For a new 15 suite apartment built on the sites of 3 existing single-family residential houses

 New dwelling units (15): $1,259 x 15= $18,885 (A)
 Demolished dwelling units (3): $1,764 x 3=  $5,292 (B)
 SSTC charge=  $13,593 (A-B)

Note: SSTC charges applicable to each development permit will be confirmed by the Development Officer at the time of application.
