1 Scope

1.1.1 This Standard covers alternate water source systems intended to process water from alternate water sources such as greywater, rainwater, atmospheric generated water, and air conditioning condensate, for use in subsurface and/or surface irrigation and toilet/urinal flushing applications, and specifies requirements for materials, physical characteristics, performance testing, and markings.

1.1.2 Alternate water source systems covered by this Standard are of the
(a) catch basin only type, intended to supply water for use in subsurface irrigation; or
Note: An example of a schematic for the catch basin only type system is shown in Figure 1.
(b) catch basin plus separate, connected, reverse osmosis and UV processing station type, intended to supply water for surface irrigation and toilet/urinal flushing applications.
Note: An example of a schematic for the reverse osmosis and UV processing is shown in Figure 2.
