Supporting infrastructure

Bearspaw NCWS Pump Station

A new large-scale facility will be constructed at the existing Bearspaw Water Treatment Plant (WTP). This facility will use large electric pumps to move an additional 100 million litres of water per day into Northwest Calgary.

Bearspaw Yard Piping and Feeder Main

A new section of large-diameter underground piping will be constructed within the Bearspaw Water Treatment Plant compound. This piping will connect the new NCWS Pump Station to the new NCWS feeder main.

Research Park Booster Station

A new medium-sized facility will be constructed at located at the location of the existing Top Hill Reservoir site off of Country Hills Blvd and Rocky Ridge Rd. This facility will use small electric pumps to move an additional 22 million litres of water per day into the Research Park pressure zone.   

Top Hill Reservoir Expansion

A new underground concrete reservoir will be constructed at Country Hills Blvd N.W. and Rocky Ridge Rd N.W. This new reservoir will have a storage capacity of 19 million litres and will be used primarily to balance water flows within the system.

Big Hill East Reservoir Tie-in

Establishes a connection from the North Calgary Water Servicing feeder main to the existing Big Hill east reservoir, with provisions for future connections to the Nose Hill east and Top Hill pressure zones.

Beddington Reservoir – Northridge Tie-in

Creates a bypass connection between the North Ridge feeder main, Beddington feeder main, and the existing reservoir, enabling reverse flow from the Spy Hill east pressure zone to the North Hill pressure zone through the North Ridge feeder main.

North/South Control Chamber

This chamber connects the new high-lift pump station, the North Calgary Water Servicing feeder main, the future South Calgary Water Servicing feeder main, and the new water treatment plant.

Energy Reduction and Future Recovery Facility

This facility will reduce water pressure inside of the existing feeder main using a sequence of pressure relief valves. In the future, The City intends to upgrade the facility to an energy recovery facility using innovative technology with electric turbines to capture the surplus energy from the flowing water and direct this energy for use at other locations. The facility will be constructed along 144 Avenue NW. 

Mountainview Pump Station Capacity Upgrades

Various upgrades to the existing Mountain View Pump Station to increasing its overall pumping capacity to from 30 million litres per day to 60 million litres per day.

Big Hill West Tie-in

This establishes a connection from the North Calgary Water Servicing feeder main to the existing Big Hill West Pressure Zone, to support growth and provide additional water redundancy in the area.
