Average Water Network Capacity by Hexagon Area

The hexagon grid utilized to present the average water network capacity data has been updated by EPCOR. As such, this version of the dataset should not be directly compared to previous versions of this dataset. The average water network capacity is intended to be understood in a relative manner: e.g. a blue area is anticipated to provide higher flows on average than a green area.

Any city block area that indicates 0-50 L/s water network capacity has been evaluated by Edmonton Fire Rescue Services (EFRS). EFRS does not associate any significant risk with these areas and can adapt a response to a fire event in these areas given the small geographical area and buildings affected. The results presented in this data were determined using computer modelling software that represented the distribution and transmission water network current in EWS's digital records as of December 9, 2024.

Modifications to the water system after this date may change the water network capacity at any given time or place. The results presented in this data represent the overall average water network capacity in an area during computer-simulated conditions at EPCOR-owned hydrants. Other factors may change the water network capacity at any given time or place.

The results presented in this data are not representative of lot-level available fire flow as outlined in the Volume 4 Design and Construction Standards. The average water network capacity ranges are only indicative of average system capacity and not indicative of EPCOR-owned hydrant spacing. A development may still require infrastructure upgrades to meet minimum hydrant spacing requirements.
