PURPOSE AND SCOPE

This manual is intended to serve as a technical reference guide in designing, installing, operating, and maintaining reservoirs using flexible-membrane materials for linings and floating covers. Source information was gathered by reviewing and collecting the experience of designers, manufacturers, and owners of flexible-membrane products that were introduced to the water industry in the early 1950s.

This manual is not intended to be a design handbook or the equivalent of an AWWA standard. Rather, it should serve as a technical reference document to be used in conjunction with AWWA D130, Standard for Flexible-Membrane-Lining and Floating-Cover Materials for Potable Water Storage, which was first approved for publication in January 1987.

Information in this manual may not apply to all types of installations or materials. In applying specific recommendations, the user must assume responsibility for accommodating a specific set of conditions.
