The Sapperton Pump Station Replacement Project represents a landmark achievement in sustainable infrastructure and community integration. As a critical component of Metro Vancouver’s wastewater management system, this facility not only enhances regional capacity but also redefines what modern public infrastructure can accomplish. Arbutus West Agency played a vital part in this project by supplying the medium-voltage (MV) and low-voltage (LV) arc-resistant switchgear and MV/LV dry-type transformers that power the new facility. Working alongside AECOM, NAC Constructors Ltd., and Metro Vancouver, Arbutus West contributed to the successful delivery of one of the most advanced wastewater pumping stations in British Columbia.

A Cornerstone of Metro Vancouver’s Wastewater System

The Sapperton Pump Station is a critical part of Metro Vancouver’s liquid waste management network. As the largest pumping station in the region, it transfers approximately one-third of all regional wastewater to the Annacis Island Wastewater Treatment Plant, serving the municipalities of Burnaby, New Westminster, Coquitlam, Port Coquitlam, and Port Moody. Replacing the original 38-year-old station was essential to meet growing population demands and ensure long-term system reliability. The new facility is designed with a peak capacity of 6.5 m³/s (562 ML/day) — enough to meet projected flows through 2051.

Arbutus West Agency: Delivering Power, Safety, and Reliability

Arbutus West Agency played a crucial role in equipping the Sapperton Pump Station with reliable and energy-efficient electrical infrastructure. The company supplied MV and LV arc-resistant switchgear and MV/LV dry-type transformers, both of which are essential to the facility’s performance and safety.

Supplying the Electrical Backbone

• Arc-resistant switchgear protects operators and equipment by safely containing and redirecting arc flash energy, a critical feature in high-voltage applications.
• Dry-type transformers offer energy efficiency, minimal maintenance, and environmentally friendly operation without the use of oil-based insulation systems.

By providing these systems, Arbutus West helped ensure that the Sapperton Pump Station operates safely, efficiently, and sustainably — even under high-demand conditions.

Collaboration with AECOM and NAC Constructors Ltd.

The success of the Sapperton project was built on strong collaboration between multiple partners.

• AECOM – the project consultant, worked closely with Arbutus West Agency to develop the preliminary electrical design and technical details, ensuring seamless integration of the supplied equipment with the overall system architecture.
• NAC Constructors Ltd. – serving as the General Contractor, brought the project to life, coordinating construction, installation, and commissioning of all systems.
• Metro Vancouver – as the end user, now operates a facility that sets new standards for reliability and community engagement.

Through this partnership, Arbutus West demonstrated not only technical expertise but also the ability to collaborate effectively on complex, multidisciplinary infrastructure projects.

Technical Excellence: Designed for the Future

The three-level, 1.9-acre Sapperton Pump Station features advanced engineering designed for long-term performance.

Key Technical Highlights

• Four shaft-driven non-clog centrifugal pumps powered by 900 HP, 4160 VAC motors
• Variable frequency drives (VFDs) for precise speed control and energy efficiency
• Temperature and vibration monitoring systems to ensure continuous reliability
• Electrical service: 69kV, 2000 amps
• Discharge system: 1500mm force main transferring wastewater to the Annacis Island treatment plant

These advanced systems are supported by the MV/LV switchgear and dry-type transformers supplied by Arbutus West, ensuring stable power distribution and safe operation across all levels of the facility.

Sustainability and Environmental Commitment

Beyond technical performance, the Sapperton Pump Station is a model of sustainable development. The site — once home to the Brunette Sawmill — was redeveloped with a strong focus on environmental restoration and community accessibility.

Environmental Enhancements Include:

• Habitat restoration and riverbank stabilization along the Brunette River
• Native landscaping to promote biodiversity
• Enhanced stormwater management systems for cleaner water discharge
• Energy-efficient systems, including the dry-type transformers supplied by Arbutus West, which reduce energy loss and eliminate oil-based cooling risks

The project’s design supports Metro Vancouver’s long-term sustainability goals, aligning infrastructure performance with environmental responsibility.

Integrating Infrastructure with Community Spaces

The Sapperton Pump Station goes beyond functionality — it’s also a community asset. The redevelopment included the creation of public green spaces, art installations, and recreational amenities, blending infrastructure with urban design.

Community Features

• Public plaza and landscaped areas for gathering and relaxation
• Interpretive materials highlighting the site’s industrial heritage
• Public washroom and picnic areas for residents and visitors
• Fishing and nature-viewing spaces along the restored riverbank
• Extension of the Brunette-Fraser Regional Greenway, enhancing connectivity for cyclists and pedestrians

This community-first approach exemplifies how engineering and public design can coexist harmoniously.

Award-Winning Collaboration

In 2022, the Vancouver Regional Construction Association (VRCA) recognized the Sapperton Pump Station Replacement with the Gold Award for Excellence in Industrial, Infrastructure, and Special Projects. This accolade highlights the project’s exceptional design, construction, and community impact.

The award reflects the collective efforts of:

• Arbutus West Agency – Supplier of MV/LV arc-resistant switchgear and dry-type transformers
• AECOM – Engineering consultant and design lead
• NAC Constructors Ltd. – General Contractor and project integrator
• Metro Vancouver – End user and project owner

Together, these organizations delivered an infrastructure project that balances technical innovation, safety, and environmental sustainability.

Why Arbutus West Agency’s Role Stands Out

Arbutus West Agency’s involvement in the Sapperton Pump Station underscores the company’s ability to deliver critical power and electrical systems for complex infrastructure projects.

Key Contributions

1. Safety First: Arc-resistant switchgear enhances personnel protection and system resilience.
2. Energy Efficiency: Dry-type transformers reduce operational losses and environmental risk.
3. Collaborative Design: Close coordination with AECOM ensured optimized performance and seamless system integration.
4. Technical Reliability: Equipment designed for longevity and low maintenance supports continuous operation.
5. Sustainability Alignment: Electrical systems that meet modern energy standards and reduce carbon footprint.

These contributions highlight Arbutus West Agency’s reputation as a trusted electrical solutions provider for major infrastructure projects across Western Canada.

Building Toward a Sustainable Future

The completion of the Sapperton Pump Station marks a milestone for Metro Vancouver — and a proud achievement for Arbutus West Agency. Through its role in supplying reliable, sustainable electrical equipment, Arbutus West helped power a facility that will serve communities for generations.
