Storm Drain, Pipe, and Sewer Flow Monitoring Services and Studies
DownStream Services, Inc. recognizes that every sewer is unique. Selecting the appropriate technology for sewer flow monitoring is paramount, to ensure 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
- pipe structural integrity
- sewer meter accessibility.
To optimize accuracy when varying sewer flow conditions are present, we use a combination of Open Channel technologies, including
- Doppler radar
- Ultrasonic pipe measurement systems.
DownStream Services, Inc. is able to
- build permanent metering stations with telemetry and SCADA
- construct custom metering manholes for municipalities and businesses
- provide low-data analysis services
- perform flow meter maintenance
- design and implement calibration programs for permanent flow metering sites.
We can also perform 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
- deterioration of aging pipe infrastructure
Comparison studies pre- and post-rehab can evaluate results of structural pipe rehabilitation.
Temporary Flow Logging for Municipalities, Businesses and Property Development
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, and we can provide the flow data needed for such a 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 may include upgrades of:
- pipe collection systems
- pumping stations
- sewer treatment facilities.
