As the owner of the sanitary utility, EPCOR contributes to the Sanitary Servicing Strategy Fund (SSSF). The contribution amount was originally set at $2.6 million per year from 1999 to 2013 when the Sanitary Servicing Strategy for the 21st Century report was approved by the City Council in 1998.

The contribution was later adjusted by the City Council to $1.3 million per year for 17 more years starting in 2007.

Since 2017 EPCOR has been making this contribution subsequent to the transfer of drainage utility from the City to EPCOR. The final utility contribution was made in 2023. No further utility contributions have been made to the SSSF.
