Performance of non-potable water reuse systems

ICS Code (Water quality in general): 13.060.01
scope:

General

This Standard assesses the performance of package wastewater treatment plants that are intended to treat either mixed-wastewater or greywater drainage and produce a treated effluent water quality suitable for non-potable water reuse applications with a treatment capacity of up to 10 000 L/d (2650 gal/d) or less.

This Standard also covers site-assembled components included in package wastewater treatment plants.

Notes:

1) In this Standard, package wastewater treatment plants intended to produce a reuse water quality suitable for authorized non-potable water applications from either mixed-wastewater or greywater drainage are also referred to as package plants.

2) This Standard is not intended to limit the use of multiple package plants to achieve an aggregate treatment capacity greater than 10 000 L/d (2650 gal/d) or as determined by the authority having jurisdiction.

3) This Standard does not cover custom-engineered wastewater treatment 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 F for information on design, warranty, and service policy.

Test methods

This Standard specifies test methods for evaluating the performance of package plants and minimum requirements regarding

a) materials;

b) design and construction;

c) operation and treatment performance;

d) markings; and

e) instructions and other documentation.

Terminology

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 (non-mandatory) to define their application.

Units of measure

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.
