Services
Wastewater Flow Monitoring
Our wastewater flow monitoring services utilize high-precision meters and real-time analytics to optimize system performance. We identify capacity constraints, verify designs, and ensure regulatory compliance by collecting and analyzing hydraulic data. This enables municipalities to make informed decisions about infrastructure investments and operational adjustments.
Clean Water Asset Management
Clean water asset management involves risk-based analysis of distribution systems to minimize non-revenue water loss. We develop tailored programs for hydrant maintenance, valve exercising, and pipeline assessments that maximize infrastructure longevity while reducing maintenance costs through predictive analytics and data-driven maintenance scheduling.
Stormwater Field Services
Stormwater field services focus on inventorying assets and evaluating drainage systems to mitigate flood risks. Our engineers use advanced inspection tools to map unrecorded infrastructure, analyze drainage flows, and design improvements that enhance system resilience against increasing storm impacts.
Hydraulic Modeling
Hydraulic modeling creates digital representations of water systems to improve operational efficiency. We analyze hydraulic characteristics to optimize network performance for wastewater, stormwater, and clean water systems, supporting data-informed planning for infrastructure upgrades and capacity expansions.
Pipeline Inspection
Pipeline inspection services employ cutting-edge technologies to assess sewer and water systems' condition. We inspect 291 million linear feet of pipelines annually, delivering accurate defect identification and structural analysis that informs rehabilitation priorities and capital improvement planning.
