WTRQ 2180 - Small Water Systems


Credit hours: 3

Prerequisites: WTRQ 2110 - Water Distribution   

Course Description:
This course applies the theories and practices of water treatment and equipment maintenance from previous water operations courses to small water treatment systems. This course includes required field experience at local drinking water treatment facilities which are classified as small water systems.

Student Learning Outcomes:
Students will be able to:

  1. Relate broad concepts, principles and theory pertaining to the hydrologic cycle and water sources to basic water treatment operations and basic regulatory requirements for small water systems. 
  2. Explain generalized water-source considerations in relation to planning, operating, and maintaining small water systems. 
  3. Identify major laws and regulations pertaining to small water systems in relation to reporting requirements for small water facilities. 
  4. Summarize strategies for establishing good public relations in small water system operations and explain the importance of developing and maintaining these relations. 
  5. Compare, contrast, and report on operations and maintenance similarities and differences at multiple locally accessible municipal drinking water treatment systems through on-site visits and staff interviews. 
  6. Describe causes, contexts, and possible solutions for common drinking-water problems. 
  7. Explain processes in solids-contact clarification units in relation to changes in water flow, turbidity, and temperature, and relate these changes to operationally helpful adjustments of flocculating chemical dosage, water recirculation rate and sludge control. 
  8. Describe various filter options and relate filter types to filtration rates and maintenance needs. 
  9. Explain the importance of well siting and wellhead protection, and contrast and compare well types and their subsurface features. 
  10. Explain how jar tests are used to determine suitable lime-soda ash water-softening procedures and suitable flocculation agent types and dosage rates.
  11. Explain the importance of corrosion and corrosion control methods in water treatment systems. 
  12. Summarize the operational significance of pre- and post-chlorination water treatments steps in relation to final water quality and optimal operational costs. 
  13. List operation and maintenance cost categories for a typical small water treatment/distribution system, and two general cost allocation methods used for estimating customer rates.
