    Overview


    Due to the inherent health risks associated with the use of non-potable water, CSA Group has published CSA B128.3 - Performance of Non-Potable Water Treatment Systems - which specifies water systems requirements for treating greywater or waste water for reuse in other applications.


    This new standard covers:


    (a) Non-potable water treatment systems for wastewater or greywater intended for treatment applications with a capacity of 10,000 litres-per-day (2,650 gallons-per-day) or less


    (b) Site-assembled components included in the non-potable water treatment system


    (c) Test methods for the performance of the plants and minimum requirements for materials, design and construction, markings, instructions and other documentation.


    CSA B128.3 complements another CSA Group standard: CAN/CSA-B128.1/B128.2 - Design and Installation of Non-Potable Water Systems/Maintenance and Field Testing of Non-Potable Water Systems. This dual-standard is an installation guide specifying the design, installation, maintenance and field testing of non-potable water systems. Both standards target manufacturers and other users of non-potable water reuse products and can be used for conformity assessment of products.

    Preface


    This is the first edition of CSA B128.3, Performance of non-potable water reuse systems.


    The development of this Standard was made possible in part thanks to the leadership and financial support of Alberta Municipal Affairs and Canada Mortgage and Housing Corporation (CMHC). Such support does not indicate endorsement of the contents of this Standard.


    This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.


    This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.


    Scope


    1.1

    This Standard covers packaged non-potable water reuse systems for wastewater or greywater that are intended for treatment applications and have a capacity of 10 000 L/d (2650 gal/d) or less.


    This Standard also covers site-assembled components included in package non-potable water reuse systems.


    Notes:


    (1) In this Standard, package non-potable water reuse systems for wastewater or greywater are referred to as package plants.


    (2) This Standard is not intended to limit the use of package reuse systems in combination for applications that require a treatment capacity greater than 10 000 L/d (2650 gal/d).


    (3) This Standard does not cover custom-engineered systems. For such systems, the authority having jurisdiction should be consulted.


    (4) Greywater diverters are covered in ASME A112.18.2/CSA B125.2.


    (5) See Annex E for information on design, warranty, and service policy.


    1.2

    This Standard specifies test methods for evaluating the performance of the package plants and minimum requirements with regard to


    (a) materials;


    (b) design and construction;


    (c) treatment performance;


    (d) markings; and


    (e) instructions and other documentation.


    1.3

    This Standard specifies two different levels (Class A and Class B) of treated reclaimed water quality. The requirements of Class A are more stringent than those of Class B (see Clause 5.9.1). The authorities having jurisdiction are responsible for determining the appropriate class of reclaimed water for each non-potable purpose.


    1.4

    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; and may is used to express an option or that which is permissible within the limits of the standard.


    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 (nonmandatory) to define their application.


    1.5

    The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only. All references to gallons are to US gallons.
