Wastewater Market
Efficient and affordable design and construction management services for wastewater conveyance facilities. Since the late 1980s we have played a crucial role in significant clean water infrastructure projects across North America, New Zealand, and Australia.
Combined Sewer Overflow (CSO)
Our engineers have practical experience that includes numerous CSO projects. For consent decree driven CSO programs, we strategically balance innovative technologies and practical designs to meet their often-tight schedules and limited budgets.
Sanitary Sewers
Our underground sewer conveyance experience ranges from large-diameter interceptor sewers to smaller-diameter force mains and trunk sewers. We offer a full range of design and construction management capabilities for conventional open-cut excavation and various trenchless technologies.
Our subject matter experts understand the unique challenges of sewer design and construction, including durability and corrosion considerations and hydraulic functional design and performance.
Stormwater & Flood Mitigation
We take into consideration resiliency and changing climates when we design underground stormwater infrastructure for governments, agencies, and contractors to meet the challenge of stormwater conveyance and flood mitigation.
We also offer the full range of construction management capabilities for conventional open-cut excavation, trenchless technologies, and large-diameter tunneling for stormwater projects. The scope of our experience varies from culvert crossings to larger diameter tunnels capable of managing flows up to 500-year storms.
Odor & Corrosion Control
Sewer tunnels live or die on their air. We design ventilation, corrosion allowance, and lining systems together rather than treating them as later add-ons, and we test the flow conditions that actually drive odour at the drop shaft.
For long-term storage tunnels we address hydrogen sulphide attack, joint detailing, and the washout risks that only show up after a decade of operation.
