Attachment E - Division H Water Standards.pdf

This is a Division H Water Standards document issued by the Special Districts Department of San Bernardino County, California, establishing standard drawings and specifications for water infrastructure construction and installation. The document provides a comprehensive table of contents referencing 20 standard drawings (H-1 through H-20) covering critical water system components including utility line protection, fire hydrant assemblies, thrust blocks, meter connections, backflow prevention devices, pressure reducing stations, valve boxes, trenching details, and related infrastructure elements. The standards also reference companion documents including the Water Division F Design Criteria (2008), Water Division G Standards (2008), and multiple revisions of Water Standard Drawings dated July 25, 2011, February 9, 2012, and June 29, 2012, collectively establishing the technical requirements and construction methodologies applicable to water projects within San Bernardino County's jurisdiction.

These water standards serve as mandatory design and construction guidelines for contractors bidding on or executing water infrastructure projects within the county, including the referenced Wildland Firefighting Helitanker Station project. The standards ensure uniformity, safety, and compliance across all water system installations by specifying approved materials, assembly configurations, and installation procedures for components such as fire hydrants, pressure regulation equipment, backflow prevention assemblies, and service connections. Contractors must adhere to these Division H standards in conjunction with all applicable design criteria and specifications when preparing bids and executing work on county water projects.
