City of Regina Water Expansion Project
$167 million
THE CITY of Regina has kicked off the second year of its $167-million,
three-year construction project which will provide a long-term plan for the
city’s water distribution network to accommodate growth up to a population
equivalent of 310,000. To address pressure and supply issues on the east
side of the city and improve system redundancy, the project design includes
a new water pumping station and two 42.5-megalitre water storage
reservoirs complete with a new 8.4-kilometre water supply line. The
implementation of the project will allow the city to continue meeting current
and future customer demands while providing safe and reliable service,
regulatory compliance and environmental stewardship. The specific
objectives of the Pumping Station and Reservoirs project include:
• Provide a pumping system with N+1 redundancy to supply water to the
eastern area of the primary distribution system. The initial capacity is to
meet projected demands in 2040 with the ability to increase capacity to
meet projected demands with a City population equivalent of 500,000.
• Provide potable water storage for the city to meet its city-wide objective
of capacity equivalent to two times average day demand. The initial capacity
is to meet projected demands for a city population equivalent up to 310,000
with the ability to increase capacity to meet projected demands with a
population equivalent of 500,000.
• Provide a chlorine boosting system.
• Provide a total trihalomethane (TTHM) reduction system for the potable
water reservoirs.
• Provide a future redundant distribution pumping system for the north
pressure zone (NPZ)
• Provide redundancy in the electrical and controls systems including

standby generators and PLCs.
• Minimize greenhouse gas (GHG) emissions for the new facility to help
the city or Regina meet their identified targets by including a 100kW solar
system and using electric air source heat pumps for heating and cooling.
The specific objectives of the Water Supply Main project include:
• Provide a dedicated potable water transmission main between the city’s
existing North Pump Station and the new Redbear Avenue Pump Station and
Reservoirs site. The main will be 8.4 km long and constructed with 900mm
PVC DR25 pipe.
• Provide flexible operation for redundant water transfer to existing city
pumping stations and reservoirs.
• Provide capacity to meet projected demands in 2040 and beyond while
setting up the city with the ability to increase capacity to meet projected
demands with a population equivalent of 500,000.
• Provide the ability to monitor and track flow within the new water main and
allow for swabbing through a swab launch and swab retrieval structures.
