Performances des systèmes de réutilisation de l’eau non potable

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.
