Coleman Engineering prepared a feasibility study report for the City of Fort Bragg to evaluate the use of brackish water reverse osmosis (RO) treatment to supplement its drinking water supply. Through a series of technical memoranda that were combined into the final study report, the study evaluated and detailed:
- Desalination system design criteria and potential facility sizing.
- Raw water sources and facility siting considerations.
- Regulatory and permitting issues and strategies.
- Construction and operating costs.
Primary considerations were brine concentrate disposal methods and location; raw water quality relative to total suspended solids TSS; potential to site the RO plant at the City’s water treatment plant or the former Georgia Pacific Mill Site to reduce capital and operating costs; sizing the facility sizing to be consistent with the City’s Urban Water Management Plan and General Plan to avoid inducing growth; local / political support for a new water supply; potential for opposition / litigation; avoidance of sensitive resources (wetlands, cultural resources); and the likely required form of environmental documentation and permitting.
