Description
The city of Carlsbad, California, has planned constructionof an ocean desalination plant capable of producingup to 50 mgd of potable drinking water. Asix-month pilot study was conducted to determinethe potential corrosion effect on distribution systemmaterials when the city replaces a portion of its currentimported, treated surface water with reverseosmosis (RO) permeate. Testing evaluated the effectof both water sources on distribution system andresidential plumbing materials such as copper pipe,brass meters, cement-mortar-lined pipe, and cast-irondistribution system gate valves.Results indicated that after a brief period of conditioning,the water quality of the desalinated seawater supplywas comparable to that of the current supply. Findingsfrom this study provide both a blueprint for evaluating theeffect of changes in water quality on corrosion outcomesand evidence of how a desalinated water supply can betreated to avoid corrosion problems when the water isintroduced into an existing distribution system. Includes 51 references, tables, figures.
