Denver, CO 80223 www.denvergov.org/doti
June, 2020
TO: All holders of Wastewater Standard Details
SUBJECT: Revisions to Wastewater Standard Details
The attached Wastewater Standard Details drawings were revised to reflect current standard construction methods, practices and procedures, and details were cleaned up to remove conflicting information, and for better clarity. Materials were not reviewed, vetted, or revised as a part of these revisions. Future revisions may include structural and material updates.
The most prominent, and only structural update in this set of revisions was to the inlet details. The original details were only to be used for inlets up to 6 feet deep, and were limited in length to a single, double or triple Number 16 inlet, or 6', 9' or 12' for Number 14 inlets. The new inlet details are applicable for inlets up to 12 feet deep, and up 75 feet long.
The attached Standard Details are to be used for all storm and sanitary sewer construction done under the jurisdiction of the City and County of Denver, Department Transportation and Infrastructure. These standards are to be used in conjunction with the technical specifications and the established ordinances of the City and County of Denver and in case of conflict, the technical specifications which are to be used in conjunction with these standards shall govern.
These drawings may be updated from time to time and the user is responsible for obtaining updated or revised standards. The City shall not be held liable for use of outdated standards by the contractor, consultant, developer, or engineer.
