pH Meter and Lift Station Calibration Notebooks

 

pH Meter Calibration Log

 

Calibration of the pH meter is essential to obtaining accurate pH measurements for wastewater samples. Because calibration is required for proper operation of your meter, the department requires that you keep a record of calibrations, either within the inspection notebook or in a separate notebook. The department has prepared an example pH meter calibration form. This form is available for your use, and is attached near the bottom of this page.

 

The following information is required in all pH meter calibration records:

 

  • Date;
  • Time;
  • Temperature;
  • Initials of person calibrating the meter;
  • The pH meter reading while calibrating with the 7 pH buffer solution;
  • The pH meter reading while calibrating with the 10 pH buffer solution;
  • The slope of the calibration;
  • The pH reading of the sample(s); and
  • Dates buffer(s) were purchased.

 

Lift Station Inspection Recordkeeping

 

Lift stations must be inspected on at least a weekly basis. Records of these inspections should be kept within a notebook, to be referenced for their operation and maintenance. The department has prepared an example lift station recordkeeping form. This form is available for your use, and is attached at the bottom of this page.

 

The following information should be included within the lift station inspection notebook:

 

  • Date;
  • Time;
  • Initials of person performing inspection;
  • Meter readings for each pump;
  • General appearance (note if there is grease buildup or if wet well baskets need to be cleaned);
  • Any maintenance done to the lift station;
  • Date of pump calibrations;
  • Pump ratings in gallons per minute; and
  • Power usage (if available).

 

Information pertaining to all inspections may either be kept in a single notebook or within several separate notebooks. If you have questions about the inspection notebooks or any of the required recordkeeping, contact SDDENR at (605) 773-3351.
