<br />3.3 Development of Nonresidential Capacity Charges
<br />The capacity charge for any new connection is the unit cost of capacity for each component times the
<br />amount of capacity of each component associated with the new connection. Capacity requirements for
<br />nonresidential connections shown in the table below are not representative of flows for every new
<br />connection. Flows for new nonresidential connections are determined by the City at the time of
<br />application for a new connection.
