One of the key services provided by Hydromax USA involves the monitoring of flow in separate and combined sewer collection systems. Since our inception, we have installed, maintained and provided data from hundreds of flow monitors per year. The success of this program can be measured by our repeat clients and additional areas we expand into each year. The basis of our flow monitoring program is our understanding of the process required to accurately monitor flows. We understand that personnel in the field and data analysts in the office see different things while performing their tasks. We also understand that frequent communication between these two groups and knowledge of the manner meters are reacting to different weather conditions is important in making the program run smoothly.
For this reason, Hydromax USA has developed an in-house tool providing communication and analysis for all personnel involved in flow monitoring. This tool is our FlowLingo because it enables our personnel to speak the flow meter language with full understanding of all the issues. The first part of this tool is the communications package. Both the field personnel and data analysts use this tool to identify all observations and problems that occur at each site. Starting with the initial site visits and evaluations, through equipment installation, maintenance and removal, notations and photos keep the two groups in close contact no matter where the field work is being conducted.
The second part of FlowLingo is the automated analysis section. Data from each site can be input to the worksheets and information can be reliably developed such as weekday and weekend dry weather average, minimum and maximum flow rates. The basis for determining dry weather periods can be adjusted to account for antecedent and soil conditions specific to the project area. With dry weather flow data identified, the next step would involve determination of wet weather volumes and rates of flow. Depending upon the project area, times of the year, antecedent conditions and rainfall intensity and duration are apparent. This can be followed with the assessment of individual rain events and the development of peaking factors and I/I coefficients. The analysis enables the identification of the following information:
- Weekday and weekend Dry Weather Flow (DWF) diurnal pattern
- Weekday and weekend DWF average, minimum and maximum flow, level and velocity
- Wet weather average, minimum and maximum flow, level and velocity
- Graphing of individual rain events showing response and recession
- Rainfall Induced Inflow & Infiltration (RDII) Volume in gallons per rain event
- I/I Coefficient per rain event
- Peaking Factor per rain event
The FlowLingo analysis tool enables our data analysts to improve the accuracy of flow monitoring projects by having information in addition to typical hydrographs and scatter plots.
