It covers criteria such as submittal requirements, horizontal and vertical alignment, thrust restraint, tunneling, corrosion control, structural requirements, appurtenances, specifications, materials and hydraulics.

The manual is a design guideline to be followed and used in conjunction with the WSSC Water Standard Details for Construction and the WSSC Water General Conditions and Standard Specifications.
