Abstract:

The delivery of demineralized water through existing distribution systems must be preceded by careful studies, and proper treatment or blending methods must be provided to avoid poor water quality and rapid corrosion. Experiences at San Diego in 1962-1964 indicate that distilled seawater can be successfully carried in an old tuberculated cast iron main grid after treatment with limestone and blending with Colorado River water. Limestone treatment alone is inadequate to protect new asbestos cement pipe from attack. A new facility placed in service in 1967 delivers distilled seawater to another section of San Diego after blending with highly mineralized well water. Provision has been made to study the effects of pure and blended waters on various pipe materials. The importance of temperature limits for consumer satisfaction is described. The very few citations found on the subject in the literature are included.
