CAN/CSA-B126 SERIES-13 (R2018)

Potable water management is important for Canadian regions experiencing water shortages and water quality issues. CSA Group has published a number of standards specifying water system requirements for treating potable water. The B126 SERIES-13 - Water cisterns standard helps ensure that drinking water storage systems are properly designed, installed and located to help prevent health risks such as contaminated drinking water and accidents. It will help jurisdictions provide their citizens with guidelines, codes and best management practices to enable the use of these systems locally. Maintenance recommendations outlined in this standard will help keep cisterns properly sealed and identify any potential structural cracks. Cracked cisterns allow surface water, insects, animals and debris to infiltrate the cavity, leading to unsanitary conditions and personal hygiene problems. Once contaminated, cisterns are difficult to keep disinfected. Highlights of B126 SERIES-13 Include: B126 complements another related standard: CSA B128.3 - Performance of Non-Potable Water Treatment Systems, which specifies the design, installation, maintenance and field testing of non-potable water systems for applications such as flushing toilets, irrigating lawns and gardens, washing automobiles, showering, bathing, washing clothes, heating and cooling.

Preface This is the first edition of the CSA B126 Series of Standards, Water cisterns. It consists of the following Standards: (a) CSA B126.0, General requirements and methods of testing for water cisterns; (b) CSA B126.1, Installation of water cisterns; (c) CSA B126.2, Commissioning and field inspection of water cisterns; (d) CSA B126.3, Operation and maintenance of water cisterns; (e) CSA B126.4, Decommissioning of water cisterns; and (f) CSA B126.5, Mobile water cisterns. These Standards are considered suitable for use for conformity assessment within the stated Scope of the Standards. The development of these Standards was made possible, in part, thanks to the financial support of Agriculture and Agri-Food Canada, Alberta Health, Canada Mortgage and Housing Corporation, Health Canada, Manitoba Water Stewardship, Saskatchewan Ministry of the Environment, Fiber Technology Corporation, and Aboriginal Affairs and Northern Development Canada. Such support does not indicate endorsement of the contents of these Standards. -------------------------------------------------------------------------------------------------------------------------------- B126.0-13 - General requirements and methodsof testing for water cisterns Scope 1.1 General This Standard specifies materials, design, manufacturing practices, methods of testing, and markings for prefabricated water cisterns for potable and non-potable applications. 1.2 Types of cisterns Cisterns covered in this Standard are (a) made of steel, stainless steel, concrete, composite materials such as fibre-reinforced plastic (FRP), and polymers such as polyethylene; Note: This Standard includes allowance for alternative materials. (b) not pressurized; (c) intended for above-ground, elevated, or buried installations, indoor and outdoor; (d) intended to serve single-family dwellings, multi-family dwellings, and commercial establishments, or form an integral part of non-municipal communal water supply systems; and (e) intended for mobile applications for replenishment of fixed installations and on-site distribution. 1.3 Cisterns not covered by the CSA B126 Series This Standard does not cover (a) water barrels and containers that are not connected to the plumbing system; and (b) cisterns that form an integral part of municipal water works or municipal water supply systems. 1.4 Requirements for potable water cisterns Specific requirements for cisterns intended for potable water applications are specified within each standard of the CSA B126 Series where applicable and identified as additional requirements for potable water cisterns. 1.5 Diction In CSA Standards, \"shall\" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; \"should\" is used to express a recommendation or that which is advised but not required; \"may\" is used to express an option or that which is permissible within the limits of the standard; and \"can\" is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.6 Dual dimensions The values given in SI units are the units of record for the purpose of this Standard. The values given in parentheses are for information and comparison only. All references to gallons are to U.S. gallons. -------------------------------------------------------------------------------------------------------------------------------- B126.1-13 - Installation of water cisterns Scope This Standard specifies requirements for installation of water cisterns. -------------------------------------------------------------------------------------------------------------------------------- B126.2-13 - Commissioning and field inspection of water cisterns Scope This Standard includes requirements for commissioning newly installed cisterns and field inspection of newly installed and existing water cisterns. -------------------------------------------------------------------------------------------------------------------------------- B126.3-13 - Operation and maintenance of water cisterns Scope This Standard specifies requirements for the operation and maintenance of water cisterns. -------------------------------------------------------------------------------------------------------------------------------- B126.4-13 - Decommissioning of water cisterns Scope This Standard specifies requirements for the decommissioning of water cisterns. -------------------------------------------------------------------------------------------------------------------------------- B126.5-13 - Mobile water cisterns Scope This Standard specifies requirements for mobile water cisterns used to (a) transport water to onsite cisterns, and (b) provide direct access to water at events and other locations.
