New Standard Details - The following Standard Details are new or have been revised. 

Please replace old details with current versions, based on subject matter (not Section Name or Number), as updated Section Names or Chapter Numbers may have changed.  The most recent/current versions will be maintained on this site.  Designers and Contractors shall be required to use the current posted version which supersedes any and all prior versions, based on the version number and version date located in the Title Block.

Printing Tips: The Standard Details were developed for printing on Tabloid (11" x 17") size paper.  They may be printed on Tabloid (11" x 17") or Legal (8.5" x 14") size paper and retain sufficient detail and text size to remain useful.  We do not recommend printing on Letter (8.5" x 11")  size paper. Remember to un-check the " Choose paper source by page size" check box when printing to any size other than Tabloid.  You may also need to select "Fit to Printable Area" in the Page Scaling drop down box.

Download Tips:  You may download the individual Standard Details as needed.  Right click the Detail Name which will open the shortcut menu window.  Select  “Save Target As” to complete the file download.

Please review Detail #0 Cross Reference – Index of Water Standard Details for a cross reference between the Old Standard Detail Number and the New Standard Detail Letter designation.
