The vendor shall supply iron castings and other specified items such as meter boxes, manhole covers, grating covers, valve box extensions, risers, and flanged bends.

All castings must meet the 2023 City of Seattle Standard Plans for Municipal Construction (or the latest edition) and the American Waterworks Association (AWWA) - 2023-Standard-Plans.
