Water Treatment Capacity Problem Statement
Max. Day (Peak Day) vs. Average Day

Anson Service Area Historical Water Use
These Peaks Can Be Managed By Operation of the
System
6
Peak Day to Average Day Ratios for Regional Water
Utilities
7
Weekend to Weekday Peaking Factors for Regional
Water Utilities
Additional Irrigation Peak Demand Drives Capital
Cost of Capacity 15.3 M for 52 days (15) per

Other Water Allocation Policy Issues
  • Designed for Flexibility
  • Weather Patterns/Climate Impact Water Use
  • Water Conservation Rate Structure Impacts
  • Development Schedules May Vary
  • Peak Capacity Relief from Lancaster Co.
  • Sets as a Precedent 1-Day/5-Day Irrigation
  • Trial Period
  • Measure Success Adapt (Summer 09 Key)

13
Other Water Allocation Policy Issues
  • Utilize No Outdoor Irrigation as Contingency Plan
