The National Codes for the water sector have been widely adopted by WSAA members and associates. Adopting utilities are required to close out options within each Code to accommodate utility needs and preferences as well as local construction practices and products. 

The Codes are supported by WSAA committees and networks that focus on broader issues such as sustainability, environmental management, asset management, water quality, quality assurance, water reuse and conservation, pressure and leakage management, health and safety, critical infrastructure protection, strategic products and construction materials.
