5. Research Objectives and Requirements
Understand individual and combined life-cycle benefits of co-siting.
Document successful and unsuccessful co-siting case studies.
Develop a decision tool

6. Proposed Approach and Collection Methods
Develop seven potential scenarios
Develop a questionnaire covering the scenarios
Contact partners to identify potential case studies
Conduct an internet search for potential case studies
Contact owners and engineers for co-siting facilities, and obtain information for survey.
Use case studies to develop model.

7. Co-Siting Scenarios 1: Power Plant – SWRO Co-siting
2: SWRO – WWTP Co-siting
3: BWRP – WWTP Co-Siting
4: SWRO – Power Plant Co-siting
5: Power Plant – BWRO Co-siting
6: SWRO – Industrial Co-siting
7: BWRO – Industrial Co-siting

16. Advantages Shared intake infrastructure
Reduced Construction, No Increase in Total Intake Volume
Shared discharge infrastructure
Reduced Construction, Outfall Blending, Beneficial Use of Brine
Land Available and Zoned
Power plant synergies
Higher Temp, Electricity Rates, Less Transmission, benefits for power plant

17. Disadvantages Life cycle of existing facility infrastructure
Opposition to Once-Through Cooling
Impacts to membrane performance
Concentration disposal limitations
Regulatory issues
Siting constraints
Patent restrictions
Operation constraints

18. Research Presented for 31 Case Studies
General:

20. Decision Tool

21. Case Study Summary 7 Co-Sited Scenarios developed
31 Case Studies Researched
Most were Scenario 1
(Power Plant -SWRO)
Remainder were Scenario 2 or 3
(SWRO-WWTP) or (BWRO-WWTP)
Capital costs comparable, O&M costs lower
Preliminary decision tool complete
