Precision at Depth, Performance Under Pressure
Complex underground infrastructure is where Whissell sets itself apart. For over five decades, we’ve delivered deep utilities, trunk mains, lift stations,
and complex tie-ins across Alberta, often in high-risk corridors, constrained urban environments, and environmentally sensitive areas.
These aren’t standard installs. These are “Whissell projects.”
Our Expertise Includes:
- Water transmission mains
- Sanitary trunk and feeder mains
- Storm trunk systems
- Deep utility relocations
- Lift stations and pump stations
- Utility diversions and complex tie-ins
- Trenchless installations and crossings
- High groundwater and shored excavations
- Engineered shoring and trench protection
- Groundwater management and dewatering
- Continuous atmospheric monitoring
How we Deliver
Pre-Planning & Forecasting
Our operations teams forecast manpower, equipment, materials, and sequencing well in advance. We identify risk early and mitigate it before it impacts the schedule or cost.
Constructability & Value
We routinely provide alternative alignments, diversion strategies, and installation methods that reduce cost, shorten schedules, and improve safety.
Over the last decade, our teams have generated millions in documented client savings through practical, field-driven solutions.
Safety at depth
- Engineered shoring and trench protection
- Groundwater management and dewatering
- Continuous atmospheric monitoring
- Strict confined space protocols
- Real-time hazard assessments
- Safety isn’t layered on, it’s planned in
Market Segments
Industrial Sites
Complex underground systems for energy, renewable, landfill, and industrial facilities. We coordinate closely with plant operations, safety teams, and multi-trade environments to maintain uptime and compliance.
Infrastructure Project
Municipal trunk mains, feeder mains, rehabilitation projects, and major relocations. We work in active corridors with traffic accommodation, public interface, and multi-agency coordination.
Suburban Developments
Full deep utility installations for residential and commercial developments, including offsite connections, trunk extensions, and stormwater systems. Our crews understand production efficiency while maintaining strict quality control and inspection standards.
