9. State Level Initiatives
NEW DEVELOPMENTS AT THE STATE LEVEL
WATER FOR 2060 LAW APPROVED
GOAL TO CONSUME NO MORE FRESH WATER IN THAN CONSUMED STATEWIDE IN 2012
EXPAND WASTEWATER REUSE AND OTHER NON- POTABLE WATER SOURCES
DEQ IPR Rule
252:628 Indirect Potable Reuse (IPR) for Surface Water Augmentation

13. Future Water Supply Portfolio (Innovative Augmentation of Caney River)

14. Concept Feasibility Study

15. Feasibility Study and Implementation
2017 Bureau of Reclamation Funding – Title XVI Feasibility Study Grant ($150,000)
2017 Bureau of Reclamation Drought Resiliency Project Implementation Grant ($750,000)

16. Regulatory Review Early Coordination and Dialogue with DEQ
Proposed IPR Rule (DEQ 252:628) Addresses Augmentation to Surface Waters
Proposed Concept is Considered Stream Discharge Subject to Water Quality (WQ) Standards
Compliance with Oklahoma WQ Standards
Fish and Wildlife Propagation (FWP)
Warm Water Aquatic Community (WWAC)
Wasteload /TMDL Study to support compliance with WQ standards

17. Wasteload Allocation Study
2016 Caney River Scoping Model and Study
Evaluated the feasibility of discharging approximately 5 to 7 miles upstream of Caney River Intake

18. Wasteload Allocation Study
Monitoring Study Plan- DEQ Approval July 2017
Time of Travel using dye-tracer study
Physical channel measurements
Sediment oxygen demand (SOD) study
River re-aeration study

19. Wasteload Allocation Study
Caney River Qual2K Model
Caney River Field Sampling Completed September- October 2017
Two different flow regimes
24.5 cfs and 96.7 cfs
Excellent flow control in the river due to COE assistance and flow management

20. Wasteload Allocation Study
In-situ Measurements

21. Wasteload Allocation Study Findings
Calibration - pH

22. Wasteload Allocation Study Findings
Calibration - Dissolved Oxygen

23. Wasteload Allocation Study Findings
Existing Low Water Dam

24. Wasteload Allocation Study Findings
Corroboration - pH

25. Wasteload Allocation Study Findings
Corroboration - Dissolved Oxygen

26. Wasteload Allocation Study Findings
Model Sensitivity – Tornado Diagram

27. Wasteload Allocation Scenarios
Summer (June 16 to October 15)
DO Minimum WQS is 5.0 mg/l
Water Temperature 30oC
Winter (October 16 to March 31)
Water Temperature 18oC
Spring (April 1 to June 15)
DO Minimum WQS is 6.0 mg/l
Water Temperature 25oC

28. Wasteload Allocation Study Findings
Proposed- 50/50 Flow Split (Summer Critical)

29. Wasteload Allocation Study Findings
Proposed- 50/50 Flow Split (Winter Critical)

30. Wasteload Allocation Study Findings
Proposed- 50/50 Flow Split (Spring Critical)

31. Feasibility Study Conclusions
Calibrated and Corroborated Model Demonstrated Assimilative Capacity
50-50 Split discharge between existing outfall and a new discharge located 5 miles upstream during summer and winter critical conditions
Model predicts insufficient assimilative capacity during spring critical conditions
Model may be overly conservative.
Additional monitoring during spring can be considered for future use

32. Innovative Augmentation
COMPARISON OF COSTS VERSUS WATER YIELD
COE RECOMMENDATION OF ADDITIONAL WATER STORAGE CONTRACTS AND PIPELINE
$92.4MM FOR MGD - $5.5MM PER MGD
CANEY RIVER AUGMENTATION USING TREATED EFFLUENT
$8.5MM FOR 4.1 MGD - $2.1MM PER MGD
NEXT STEPS
DEQ Approval- 2018
DEQ & OWRB Water Quality Pan Amendment
Design and Implementation
Treated Effluent Pump Station and Pipeline- 3 Year Schedule
