Current through August 31, 2023
The terms "department," "person," and "waters" have the meaning
				provided for those terms in Section
				39-103, Idaho Code.
				(4-6-23)
01.
Beneficial
			 Use
. Uses of the water of Idaho including, but not limited to, domestic
			 water supplies, industrial water supplies, agricultural water supplies,
			 navigation, recreation in and on the water, wildlife habitat, and aesthetics.
			 The beneficial use depends upon actual use, ability of the water to support a
			 non-existing use either now or in the future, and its likelihood of being used
			 in a given manner. The use of water for wastewater dilution or as a receiving
			 water for a waste treatment facility effluent is not a beneficial use.
			 (4-6-23)
02.
Biochemical
			 Oxygen Demand (BOD)
. Amount of oxygen necessary to satisfy the
			 biochemical oxidation requirements of the organic materials at the time the
			 sample is collected; unless otherwise specified, this term means the five (5)
			 day BOD (BOD5). (4-6-23)
03.
Buffer Distances
. Specified distance between an actual point of
			 recycled water use and a land feature or resource use, such as wells, adjoining
			 property, inhabited dwellings, or other features. (4-6-23)
04.
Ground Water Recharge
.
			 Process of adding recycled water to the zone of saturation. (4-6-23)
05.
Industrial Wastewater
. All
			 wastewater, treated or untreated, that is not defined as municipal wastewater.
			 (4-6-23)
06.
Land
			 Application
. Process of distributing wastewater or recycled water to the
			 land surface. (4-6-23)
07.
Landscape Impoundment
. Any lake, pond, or other water-holding feature
			 constructed or managed to store recycled water where swimming, wading, boating,
			 fishing, and other water-based recreational activities are prohibited.
			 Landscape impoundment created for storage may incidentally serve a landscaping
			 or aesthetic purpose. (4-6-23)
08.
Maximum Day Flow
. Largest volume of flow received during a 24-hour
			 period expressed as a volume per unit time. (4-6-23)
09.
Modal Contact Time
. Amount
			 of time elapsed between the time a tracer, such as salt or dye, is injected
			 into the influent at the entrance to a chamber and the time the highest
			 concentration of the tracer is observed in the effluent from the chamber.
			 (4-6-23)
10.
Municipal
			 Wastewater
. Wastewater containing sewage and associated solids, whether
			 treated or untreated. Municipal wastewater, also known as domestic wastewater,
			 may contain industrial wastewater. (4-6-23)
11.
Non-Potable Mains
. Pipelines
			 that collect and/or convey non-potable discharges from or to multiple service
			 connections. Examples include sewage collection and interceptor mains, storm
			 sewers, non-potable irrigation mains, and recycled water mains.
			 (4-6-23)
12.
Non-Potable
			 Services
. Pipelines that convey non-potable discharges from individual
			 facilities to a connection with the non-potable main. Term also refers to
			 pipelines that convey non-potable water from a pressurized irrigation system,
			 recycled water system, and other non-potable systems to individual consumers.
			 (4-6-23)
13.
Non-Potable
			 Water
. Any fluids that do not meet the definition of potable water.
			 (4-6-23)
14.
Nephelometric
			 Turbidity Unit (NTU)
. Measure of turbidity that compares the intensity
			 of the light scattered by the sample under defined conditions with the
			 intensity of the light scattered by a standard reference suspension under the
			 same conditions. (4-6-23)
15.
Peak Hour Flow
. Largest volume of flow received during a one (1)
			 hour period expressed as a volume per unit time. (4-6-23)
16.
Plan of Operation
. Manual
			 that describes in detail the current operation, maintenance, and management of
			 a reuse facility. (4-6-23)
17.
Point of Compliance
. Point in the reuse facility where the
			 recycled water must meet the requirements of the permit. A permit may require
			 more than one (1) point of compliance within the facility depending on the
			 constituents to be monitored. (4-6-23)
18.
Potable Water
. Water used by
			 humans for drinking, bathing for purposes of personal hygiene (including
			 hand-washing), showering, cooking, dishwashing, and maintaining oral hygiene.
			 In common usage, the terms "culinary water," "drinking water," and "potable
			 water" are frequently used as synonyms. (4-6-23)
19.
Purple
. For the purposes of
			 these rules, purple is specified as Pantone 512, 522, or equivalent.
			 (4-6-23)
20.
Rapid
			 Infiltration System
. Permeable systems designed and operated for high
			 rates of recycled water infiltration followed by rapid percolation using
			 wetting and drying cycles. (4-6-23)
21.
Recycled Water
. Water
			 treated by a wastewater treatment system and used according to these rules.
			 (4-6-23)
22.
Restricted
			 Public Access
. Preventing public entry within the area or a facility's
			 point of reuse and the buffer distance around the area by site location or
			 physical structures such as fencing. (4-6-23)
23.
Reuse
. Use of recycled water
			 or wastewater for beneficial purposes including irrigation, ground water
			 recharge, landscape impoundments, toilet flushing in commercial buildings, dust
			 control, and other uses. Also referred to as Beneficial Reuse.
			 (4-6-23)
24.
Reuse Facility
			 or Facility
. Structure or system designed or used for reuse of municipal
			 or industrial wastewater including, but not limited to, industrial and
			 municipal wastewater treatment facilities, pumping and storage facilities,
			 pipeline and distribution facilities, and the property to which the wastewater
			 or recycled water is used. Does not include industrial in-plant processes and
			 reuse of process waters within the plant. (4-6-23)
25.
Sewage
. Water-carried human
			 wastes from residences, buildings, and industrial establishments and other
			 places, together with ground water infiltration and surface water as may be
			 present. (4-6-23)
26.
Subsurface Distribution System
. System with a point of discharge
			 beneath the earth's surface. (4-6-23)
27.
Turbidity
. Measure of the
			 interference of light passage through water, or visual depth restriction from
			 the presence of suspended matter such as clay, silt, nonliving organic
			 particulates, plankton, and other microscopic organisms. Operationally,
			 turbidity measurements are expressions of certain light-scattering and
			 absorbing properties of a water sample. Turbidity is measured by the
			 nephelometric method. (4-6-23)
28.
Wastewater
. Combination of liquid or water and pollutants from
			 activities and processes occurring in dwellings, commercial buildings,
			 industrial plants, institutions, and other establishments, together with any
			 ground water, surface water, and storm water that may be present; liquid or
			 water that is chemically, biologically, physically or rationally identifiable
			 as containing blackwater, gray water, or commercial or industrial pollutants;
			 and sewage. (4-6-23)
