Flow Monitoring



Storm Drain, Pipe, and Sewer Flow Monitoring Services and Studies


DownStream Services, Inc. recognizes that every sewer is unique. Selecting the appropriate technology for the sewer flow monitoring is paramount to insuring accurate data recovery. Prior to performing a pipe flow study, our team analyzes sewer site conditions to determine a variety of variables, including sewer flow hydraulics, pipe sedimentation, structural pipe integrity, and sewer meter accessibility.
To optimize the accuracy when varying sewer flow conditions are present, DownStream Services, Inc. utilizes a combination of Open Channel technologies, including Doppler, radar and ultrasonic pipe measurement systems. DownStream Services, Inc. has the capability to perform both temporary and permanent sewer flow monitoring studies for a variety of applications:


Sewer and Pipe Condition Assessment and Rehabilitation

Pre-rehab studies can pinpoint problem areas of inflow and infiltration (I&I), sewer blockages, flow capacity, and pipe deterioration of aging infrastructure. Comparison studies pre- and post-rehab can evaluate results of structural pipe rehabilitation.


Temporary Flow Logging for Municipalities, Businesses and Property Development Purposes

Valuable data can be provided for municipalities with growing communities and those with seasonal industry or tourism. A capacity study is often required prior to new property development, Downstream Services provides the flow data needed for the study.


Storm Drain and Sewer Overflow Studies Metering Water Quality

In order to quantify overflow of storm drains or combined sewer overflow (CSO) systems, sewer flow meters can be programmed to activate water quality samplers for flow-weighted discrete or composite samples.


Engineer Master Plans - Permanent Metering of Diurnal Flow Patterns

By continuously metering diurnal flow patterns and quantities for specific periods of time, future needs can be projected. Such needs include upgrades of pipe collection systems, pumping stations, and sewer treatment facilities.

DownStream Services, Inc. is able to build permanent metering stations with telemetry and SCADA, and construct custom metering Manholes for municipalities and businesses. We provide low data analysis services, as well as flow meter maintenance, and calibration programs for permanent flow metering sites.
