Engineering Directives and Policies

What are Engineering Directives?

RWRD is in the process of clarifying and improving the design standards and details for sewer conveyance systems. New standards and modifications to standards are included in Engineering Directives.

Please incorporate these Directives in your design of sewer conveyance systems.

Engineering Directives can also be found under Standard Details, organized by section.
