1 Wastewater Capacity Evaluation Update January 7, 2019

2 Future Wastewater Needs Decision Factors driving the decision Design-Permitting-Construction timeline Will take ±4 years to deliver a project Raleigh contract expiration Current commitments Impacts Actual Flow vs. Permitted Flow vs. Allocated Flow Delayed decision will require limits on development approvals

3 Considerations Community needs Best Value vs. Cost to Customers

4 Since the Last Update Re-evaluated projected flows based on most recent allocations made and requested to the Town 20-year planning period Explored options to extend need to have additional capacity (ongoing) Staff met with Johnston County, City of Raleigh, 3 rd Party Operators, Legislators Used Rate Model to determine impact of options explored on user rates (ongoing)

5 Variables in Options Considered Obtaining Additional Capacity in Clayton vs. JoCo ~45% in JoCo and 55% in Clayton ~20% in JoCo and 80% in Clayton All Flow Treated in Clayton Timing Raleigh Contract ends in 2027 vs Maximizing Existing Resources Building one new facility vs. two facilities (maintaining Little Creek WRF and building smaller new facility) Phasing Is phasing a feasible option to spread out costs for each scenario considered?

6 Options Considered Raleigh Contract Expires 2027 Raleigh Contract Expires 2032 ~45% of ~20% of Flow ~20% of ~45% of Flow Treated in Flow Treated All Flow Flow Treated Treated in JoCo; 55% in JoCo; 80% Treated in JoCo; 55% JoCo; 80% All Flow Treated in Treated in in Treated in Treated in Treated in Clayton (A) Clayton (B) Clayton (All) Clayton (C) Clayton (D) Clayton (All) One New Facility 1A 1B 1BAll 1C 1D 1DAll Two facilities (Little Creek WRF and smaller new facility) 2A 2B 2BAll 2C 2D 2DAll This represents 20 options for consideration (including some options as phased)

7 Options Considered for Rate Study Of all the options considered, 5 options were supplied for the Rate Model 1B One Plant; ~20% of Flow Treated in JoCo; 80% Treated in Clayton 2B Same as 1B but running Two Plants 1C One Plant; ~45% of Flow Treated in JoCo; 55% Treated in Clayton 2C Same as 1C but running Two Plants 1DAll One Plant, Clayton treats all flows (no flow sent to Raleigh or JoCo by 2037)
