What is a System Development Charge (SDC) and how is it determined?
This is a charge that reflects the prior investment made by existing customers. The basis for a buy-in method SDC is that new customers will be charged for capacity based on the value of available capacity in the existing system. Essentially, new customers are buying their share of capacity from the existing customers.


The SDC for residential properties are based on number of units (single family detached to multi-unit dwellings). The SDC for commercial properties is based on meter size. Refer to the current Rules and Regulations Appendix 3 for the Schedule of SDCs.
