  5. Reads and inputs flow measurements, storage levels and water demand to determine the pumps needed and the rate of treatment in order to maintain an adequate water supply and report water use.
  6. Operates and maintains equipment for water treatment residuals processing including sludge dewatering and hauling equipment.
  7. Performs general maintenance and calibration of all equipment, including heavy machinery, and/or delicate laboratory and plant instrumentation in order to maintain maximum performance of equipment and processes.
  8. Computes water production, chemicals used, chemical dosage, and chemical inventory in order to prepare daily summary for computer input.
  9. Assigns work and provides training in operations and maintenance of all water related systems to coworkers and student operators as necessary.
  10. Collects and prepares water samples for tests to be performed by outside agencies, as required by law, including:
  11. State Hygienic Laboratory Iowa Department of Natural Resources U.S. Environmental Protection Agency Iowa Department of Health
  12. Performs duties outside the Water Plant, including work with ion-exchange softeners, swimming pools, deionizers, distillation equipment, reverse osmosis equipment, remote campus water and water distribution systems and water meter reading and maintenance.
  13. Performs distribution system cross-connection/contamination investigations.
  14. Samples and monitors storm water systems and operates and maintains dechlorination treatment systems per NPDES permit requirements.
  15. Operates and maintains building and central chilled water production equipment including chemical storage and treatment systems for disinfection and corrosion control.
  16. Attends conferences, meeting and/or schools required in order to obtain and maintain Iowa Grade II, or higher, Water Plant Operator certification, other required certifications and proficiency in mandated safety areas such as confined space entry, lock-out safety, fall safety, and other areas as required.
