The purpose of this standard is to define the minimum disinfection, sampling, and handling requirements when installing new mains or repairing a main break. These requirements identify when disinfection is required based on the level of public health risk. Included in this standard are requirements for disinfection of water mains, preparation and sanitary handling of water mains, application of chlorine, and sampling and testing for free chlorine residuals and the presence of coliform bacteria.
The purpose of this standard is to provide minimum requirements for the design, construction, inspection, and testing of new welded carbon steel tanks for the storage of water at atmospheric pressure.
This standard for disinfection of water-storage facilities describes materials, facility preparation, application of disinfectant to interior surfaces of facilities, and sampling and testing for the presence of coliform bacteria, chlorine residual, and acceptable aesthetic water quality. The standard also includes disinfection procedures for underwater inspection and/or cleaning of potable-water-storage facilities but does not describe the technical aspects of underwater inspection and/ or cleaning.
The purpose of this standard is to define the minimum procedures for the dechlorination of chlorinated or chloraminated water being discharged, including regulations, discharge site preparation, sampling and testing of discharge water, various methods of dechlorination, and dechlorination chemicals. This standard can be referenced in specifications for the dechlorination of low-chlorinated or highly chlorinated water discharges into the environment. The stipulations of this standard apply when this document has been referenced, and then only to dechlorination.
This standard describes underground installation and pressure testing requirements for polyvinyl chloride (PVC) and molecularly oriented polyvinyl chloride (PVCO) pressure pipe and fittings used to transport potable water, reclaimed water, irrigation water, and wastewater, or for the conveyance of any fluid compatible with PVC or PVCO. This includes products that comply with ANSI/AWWA C900, ANSI/AWWA C907, or ANSI/AWWA C909. These piping systems often contain components made from other materials. It may be necessary to supplement this standard with special requirements not included in this standard.
The purpose of this standard is to provide the minimum requirements for steel water pipe, 6 in. (150 mm) and larger, including materials and quality of work, fabrication, and testing of pipe and special sections.
The purpose of this standard is to provide the minimum requirements for the installation of ductile-iron potable water, wastewater, reclaimed water, and raw water mains and their appurtenances, including materials, dimensions, tolerances, and testing procedures.
Selection, installation, field testing, and maintenance of all types of valves used in water distribution systems.
The purpose of this standard is to provide the minimum requirements for polyethylene sheet and tubes to be used for external corrosion protection of buried ductile-iron pipe, fittings, and appurtenances.
The purpose of this standard is to provide minimum requirements and dimensions for a variety of steel flanges for attachment to steel water pipe and fittings
