body
INFORMATION CONTACT:
John Shutak, Engineering Division Director, 704-283-3651
ACTION REQUESTED:
Receive status update on wastewater treatment capacity for the Twelve Mile Creek, Crooked Creek, Olde Sycamore, Tallwood, and Grassy Branch facilities.
BACKGROUND:
Union County Water is closely monitoring the wastewater treatment capacities at our Water Reclamation Facilities. Permitting Capacity is evaluated using the Actual Plant Flows plus the Permitted/Obligated Flows (unconnected). Union County Water was asked to provide regular updates. Below information is up to date through October 2021.
Twelve Mile Creek
• Permitted Capacity (MGD) = 7.5
• Actual Average Daily Flow (MGD) = 5.855
• Actual + Permitted Obligated Flows (MGD) = 7.348
• Percent of Permitted Flow Used = 98.0%
• Actual Rainfall (in) = 1.1
Crooked Creek
• Permitted Capacity (MGD) = 1.9
• Actual Average Daily Flow (MGD) = 0.952
• Actual + Permitted Obligated Flows (MGD) = 1.512
• Percent of Permitted Flow Used = 79.6%
• Actual Rainfall (in) = 1.1
Olde Sycamore
• Permitted Capacity (MGD) = 0.15
• Actual Average Daily Flow (MGD) = 0.037
• Actual + Permitted Obligated Flows (MGD) = 0.037
• Percent of Permitted Flow Used = 24.7%
• Actual Rainfall (in) = 1.1
Tallwood
• Permitted Capacity (MGD) = 0.05
• Actual Average Daily Flow (MGD) = 0.029
• Actual + Permitted Obligated Flows (MGD) = 0.029
• Percent of Permitted Flow Used = 58.0%
• Actual Rainfall (in) = 2.0
Grassy Branch
• Permitted Capacity (MGD) = 0.05
• Actual Average Daily Flow (MGD) = 0.049
• Actual + Permitted Obligated Flows (MGD) = 0.050
• Percent of Permitted Flow Used = 100.2%
• Actual Rainfall (in) = 1.4
In addition to the wastewater treatment capacities, the following summarizes flow volumes associated with development projects that are in the planning and review process within the 12-mile Creek and Crooked Creek WRF service areas. The information shown is up to date through October 2021.
