The Sanitary Report calculates key dry weather sanitary flow metrics for a specified monitoring period.

From the Monitoring Station pop-up menu, select the bottom icon (Analysis Tools) and Sanitary Report from the drop-down menu. Alternatively, you can select Sanitary Report under Tools in the hamburger menu, in which case you would have to define the Organization, Project, Service, and Monitoring Station in addition to the configurations noted below.

The Sanitary Report takes as inputs:

  • Flow sensor and rain gauge data associated with a single monitoring site
  • The total contributing population upstream of the monitoring station (defined in Station Details under the “Attributes” tab)
  • The total area of the contributing catchment (defined in Station Details under the “Attributes” tab)

The Sanitary Report provides three outputs:

  • A data chart of the flow and rainfall data over the specified time period
  • The patterns of all dry weather data over a twenty-four (24) hour period (showing horizontal indicators for calculated average dry weather flow and groundwater infiltration, and flow patterns for weekdays, weekends, and all days)
  • Dry weather flow parameters for the monitoring station

The following parameters are reported:

  • Average dry weather flow (DWF), measured rate and per capita
  • Average sewage flow (DWF less groundwater infiltration)
  • Average daily minimum DWF
  • Average daily peak DWF
  • Groundwater infiltration (GWI) (calculated as specified in the “Configuration” tab)
  • % GWI in average DWF
  • Measured peaking factor (compares the average daily peak DWF to the average DWF)
  • Harmon peaking factor (an empirical formula used to determine maximum hourly design flow rate, taking population as an input)

The Sanitary Report is run and/or modified using the “Configuration” tab on the right-hand side of the page.

The user can set:

  • Flow Sensor and Rain Gauge (defaulted to originating station if accessed through the Monitoring Station pop-up menu)
  • Population and catchment area (defaulted to the selected station attributes, but customizable by selecting “Enter …” from the drop-down menu)
  • Time range, either customizable or whole extent of monitoring period
  • Groundwater infiltration (GWI) calculation parameters, either as a percentage of minimum DWF or as a static area-weighted infiltration rate

The red asterisk denotes required fields.

The display options for the Dry Weather Flow Pattern can be modified using the “Options” button (all patterns are defaulted on).

The Dry Weather Flow Pattern and Dry Weather Flow Parameters can be exported as .csv.
