The definitions in this section
apply throughout this chapter unless the context clearly requires
otherwise.
(1) "Agricultural industrial process water" means water that
has been used for the purpose of agricultural processing and has
been adequately and reliably treated, so that as a result of that
treatment, it is suitable for other agricultural water use.
(2) "Agricultural processing" means the processing of crops
or milk to produce a product primarily for wholesale or retail
sale for human or animal consumption, including but not limited
to potato, fruit, vegetable, and grain processing.
(3) "Agricultural water use" means the use of water for
irrigation and other uses related to the production of
agricultural products. These uses include, but are not limited
to, construction, operation, and maintenance of agricultural
facilities and livestock operations at farms, ranches, dairies,
and nurseries. Examples of these uses include, but are not
limited to, dust control, temperature control, and fire control.
(4) "Constructed beneficial use wetlands" means those
wetlands intentionally constructed on nonwetland sites to produce
or create natural wetland functions and values.
(5) "Constructed treatment wetlands" means wetland-like
impoundments intentionally constructed on nonwetland sites and
managed for the primary purpose of further treatment or retention
of reclaimed water as distinct from creating natural wetland
functions and values.
(6) "Direct groundwater recharge" means the controlled
subsurface addition of water directly into groundwater for the
purpose of replenishing groundwater.
(7) "Domestic wastewater" means wastewater from greywater,
toilet, or urinal sources.
(8) "Greywater or gray water" means domestic type flows from
bathtubs, showers, bathroom sinks, washing machines, dishwashers,
and kitchen or utility sinks. Gray water does not include flow
from a toilet or urinal.
(9) "Industrial reuse water" means water that has been used
for the purpose of industrial processing and has been adequately
and reliably treated so that, as a result of that treatment, it
is suitable for other uses.
(10) "Land application" means use of reclaimed water as
permitted under this chapter for the purpose of irrigation or
watering of landscape vegetation.
(11) "Lead agency" means either the department of health or
the department of ecology that has been designated by rule as the
agency that will coordinate, review, issue, and enforce a
reclaimed water permit issued under this chapter.
(12) "Nonlead agency" means either the department of health
or the department of ecology, whichever is not the lead agency
for purposes of this chapter.
(13) "Person" means any state, individual, public or private
corporation, political subdivision, governmental subdivision,
governmental agency, municipality, copartnership, association,
firm, trust estate, or any other legal entity whatever.
(14) "Planned groundwater recharge project" means any
reclaimed water project designed for the purpose of recharging
groundwater.
(15) "Reclaimed water" means water derived in any part from
wastewater with a domestic wastewater component that has been
adequately and reliably treated, so that it can be used for
beneficial purposes. Reclaimed water is not considered a
wastewater.
(16) "State drinking water contaminant criteria" means the
contaminant criteria found in the drinking water quality
standards adopted by the state board of health pursuant to
chapter 43.20 RCW and the department of health pursuant to
chapter 70.119A RCW.
(17) "Streamflow or surface water augmentation" means the
intentional use of reclaimed water for rivers and streams of the
state or other surface water bodies, for the purpose of
increasing volumes.
(18) "Surface percolation" means the controlled application
of water to the ground surface or to unsaturated soil for the
purpose of replenishing groundwater.
(19) "User" means any person who uses reclaimed water.
(20) "Wastewater" means water-carried wastes from
residences, buildings, industrial and commercial establishments,
or other places, together with such groundwater infiltration and
inflow as may be present.
(21) "Wetland or wetlands" means areas that are inundated or
saturated by surface water or groundwater at a frequency and
duration sufficient to support, and that under normal
circumstances do support, a prevalence of vegetation typically
adapted to life in saturated soil conditions. Wetlands generally
include swamps, marshes, bogs, and similar areas. Wetlands
regulated under this chapter shall be delineated in accordance
with the manual adopted by the department of ecology pursuant to
RCW 90.58.380.
