WASTEWATER FACILITY IMPROVEMENT DESCRIPTION
A.10.1 PURPOSE
The Parties acknowledge that the Concessionaire has subcontracted its responsibilities set forth in the Concession Agreement with respect to the sewage collection system services of the Wastewater Facility to the Contractor pursuant to the O&M Subcontract. The purpose of this Schedule is to identify the Wastewater Facility Improvements that Concessionaire anticipates that Contractor will proceed to design and construct in accordance with the O&M Subcontract and the Final Work Authorization. Contractor agrees that, following the Effective Date, it will diligently pursue the completion of the Wastewater Facility Improvements in accordance with Article 6 of the O&M Subcontract. Concessionaire shall have the discretion, exercised in accordance with Prudent Industry Practices, to determine the precise order and schedule for the design and construction of the Wastewater Facility Improvements.
A.10.2 DESCRIPTION OF WASTEWATER FACILITY IMPROVEMENTS
The description of the Wastewater Facility Improvements set forth in this Schedule is preliminary in nature and requires further refinement and development as to the scope, design, cost and construction of such Wastewater Facility Improvements. The preliminary Cost Estimate set forth in this Schedule for each Wastewater Facility Improvement is only an estimate of the costs to design and construct each of the Wastewater Facility Improvements. The preliminary Cost Estimates are not fixed or guaranteed prices and Concessionaire acknowledges that Contractor has made no representation or warranty that the Wastewater Facility Improvements can be designed and/or constructed for the amounts set forth in the Cost Estimates. The preliminary Cost Estimate on the remaining pages of this Schedule does not include any inflation adjustment. 1 OHSUSA:751602174.1

Proposed Capital Improvement Project (CIP)
Project No. / Ranking:
Name of Project: Wastewater Treatment Plant Improvements (including SCADA at the Problem or Opportunity:
rated capacity is adequate based on current average flows of 7.2 MGI and potential development growth of 3.0 MGD (Foothill Boulevard Recommended Solution:
at 2.0 MGD each (6.0 MGD total). The improvements include Measurable Benefits: Total plant rate capacity of 12.0 MGD (Trains 2-4 2.0 MGD each, Train 5 6.0 MGD). Adequate redundancy to assure that the plant can meet demands with the largest process units out of service. Compliance with all RWQCB regulations.
Basis of Recommendation: Field investigations and extensive analysis performed by Contractor and RW Beck, discussions with local operations staff and the RWQCB.
Additionally, flow testing was performed to confirm accuracy of meters at the plant. The result, 72 gpcd, was in between the plant influent and effluent flow readings.
Assumptions / Risks: Normal construction risks associated with retrofit projects exist.
Primary Driver: Asset Renewal

0&M Subcontract Schedule A.10 - Wastewater Facility Improvement Rialto Wastewater Facility and Water Facility Description City of Rialto
Proposed Capital Improvement Project (CIP)
Project No. / Ranking: S6
Name of Project: Short Sewer Main Replacements on W. Randall, AT&SF RR, E. Ist, N.
Willow, N. Riverside, and N. Pepper (2,410 feet total)
Problem or Opportunity: Sewers are surcharged and/or could overflow under current conditions.
Recommended Solution: Replace 330' of 10" with 15" on W. Randall; 570' of 8" with 12" on AT&SF RR; 300' of 8" with 12" on E. 1"; 210' of 8" with 10" on N Willow; 180' of 8" with 10" on N. Riverside; and 820' of 8" with 10"° on N. Pepper.
Measurable Benefits: No surcharge or overflow under current conditions.
Basis of Recommendation: RW Beck hydraulic modeling. Surcharging on AT&SF RR, E. 1$, N.
Willow, N. Riverside, and N. Pepper confirmed with Veolia operator.
Assumptions / Risks: The proposed improvements reflect internal growth but not external growth such as the proposed Lytle Creek development. Normal construction risks associated with unknown underground conditions Primary Driver: Reliability and Quality of Service
