Demineralized water distribution system standard required

2002

Hi,

I'm looking for international standards for use in a municipal demineralized water distribution system. The majority of the tenants of Ras Laffan require demineralized water, not potable so a demineralized water distribution system is being planned. It is highly desirable that it be built to some recognized international standard and we're looking for at least one.

Yours,
