About the Committee & 7th Edition
Standard Specifications for Water & Sewer Construction Committee exists to provide a "Convenient standard working document" which could be used in the preparation of documents for the construction of sewers and water mains. The purpose of these Standard Specifications is to reduce document assembly time, and provide a high quality product which will facilitate agency reviews and reduce bidder time.
The committee consists of Owners, Contractors, and Engineers as well as representatives from relevant state agencies who act in an advisory capacity.
The 2013 update, published in 2014, comments were solicited from all groups previously involved with the publication of the manual, those who purchased the 6th Edition, and from throughout the design and construction industries. Nineteen formal comments were submitted to the committee for consideration during the 2013 update published in 2014. Significant changes include:
- Division II - Allow CA -7 gradient aggregate for bedding and haunching.
- Division III - Clarify fitting and joint standards with HDPE Pipe
- Division III - Allow Polypropylene Pipe for sanitary sewers
- Division III - Add ASTM D3262 for GFRPM Pipe
- Division IV - Correct technical references
- Division V - Allow concrete pipe joints complying with ASTM Standard C 1628
- Division V - Allow Polypropylene Pipe for storm water sewers
Multiple Divisions - Clarify that when installation standards outlined in this manual differ from manufacturer's recommendations, the more stringent of the two shall apply.
