Service Offerings
Six Core Service Areas
Covering the full lifecycle of sewer system analysis — from development approval to long-term asset management and regulatory compliance.
Sewer Flow Monitoring
Continuous measurement of wastewater flow rate, velocity, and depth. Cellular telemetry with near real time uploads. 95%+ data uptime target.
Learn MoreSewer Capacity Studies
PE-stamped certification and LVL I & II inspection support for building permits, sewer connection agreements, and development entitlements. Most studies complete in 7–14 days.
Learn MoreRDII Analysis
RTK unit hydrograph method. Supports CMOM programs, EPA consent decree compliance, SSO reduction, and CIP prioritization.
Learn MoreHydraulic Model Calibration
15-minute DWF diurnal datasets for EPA SWMM, InfoWorks ICM, SewerGEMS, XPSWMM, and ESRI. Ready for direct import.
Learn MoreFlow Meter Installation

Case Studies
What Field Data Reveals
Models built on assumptions routinely misrepresent actual conditions. These are the corrections measured data made possible.
Field data corrected a trunk sewer replacement
A 47-meter monitoring network revealed the city's hydraulic model had overestimated peak flows by 65%.
View Case StudyMonitoring changed the diagnosis entirely
18-month monitoring identified inflow defects — not deteriorated pipe — as the primary SSO source.
View Case StudyMonitoring investment that funded itself
Three monitoring programs generated calibration data that justified $4.1M in follow-on engineering contracts.
