WD (Withdrawals) – Documentation shall consist of pumpage records in annual average gpd as metered at the

The pumpage records shall be totalized for a total withdrawal quantity for the reporting period.
IM (Imported Water ) – Documentation shall consist of a summary report of the water purchased or otherwise
obtained in bulk from another utility for potable use in the service area in annual average gpd, and the supplier's
WUP number(s), or consumptive use permit number if the supplier is in another water management district.
Quantities shall be determined at the departure point from the supplier's service area. Irrigation water imported into
the service area from another utility must be documented separately according to the use type (for example,
commercial, residential, recreational/aesthetic).
EX (Exported Water) – Documentation shall consist of annual average gpd transferred in bulk quantities to
another utility, and the recipients's WUP number(s), or consumptive use permit number if the recipient is in another

quantity.
TL (Treatment Losses) – Documentation shall consist of the annual average gpd lost in routine treatment for
potability. Examples of treatment losses types are desalination reject, membrane cleaning and sand filtration
backwash. Treatment losses are calculated as raw water into the plant minus treated water out of the plant. In
addition, no more than 1% of treated water volume delivered to the distribution system for flushing distribution lines
for potability may be deducted. Treated water volume delivered to the distribution system includes water from
withdrawals plus imports, minus exports, minus treatment losses. Treatment loss and line flushing quantities shall
be separately calculated and documented.

(given in Appendix C of Part D of the Water Use Permit Information Manual), as applicable, and supporting
