Current through Register Vol. 40, No. 24, July 15, 2024
A. A water plan
				shall include current information on existing water sources.
B. A water plan shall include, for community
				water systems using ground water, the name and identification number of the
				well or wells, the well depth, the casing depth, the screen depth (top and
				bottom) or water zones, the well diameter, the design capacity for the average
				daily withdrawal and maximum daily withdrawal, the system capacity permitted by
				Department of Health, and the annual and monthly permitted amounts contained in
				ground water withdrawal permits for all wells located within ground water
				management areas.
C. A water plan
				shall include, for community water systems using surface water reservoirs, the
				name of the reservoirs, the sub-basins in which the reservoirs are located, the
				drainage area, the amount of on-stream storage available for water supply, the
				design capacity for average daily and maximum daily withdrawals from the
				reservoirs, the safe yield of the reservoirs, the capacity of any associated
				water treatment plant, the Department of Health permitted capacity of the
				systems, and any limitations on withdrawal established by permits issued by the
				department. For a community water system that operates a system of
				interconnected reservoirs, the reporting of the design capacity for
				withdrawals, designed average daily withdrawal, the designed maximum daily
				withdrawal and the safe yield may be for the entire system or may be reported
				as subsets of the system. The plan shall designate which reservoirs and which
				intakes constitute a system for the purposes of this paragraph. The plan must
				report the drainage area and amount of storage available for water supply from
				each reservoir independently.
D. A
				water plan shall include, for community water systems using stream intakes, the
				name of the stream or river, the drainage area of the intake, the sub-basin in
				which the intake is located, the design capacity for average daily and designed
				maximum daily withdrawal from the stream, the safe yield, the lowest daily flow
				of record, the design capacity of the pump station, the design capacity of the
				water treatment plant, the capacity of the system permitted by the Department
				of Health, and any limitation on withdrawals established by permits issued by
				the department.
E. To the extent
				that information is available, a water plan shall include a list of all
				self-supplied users of more than 300,000 gallons per month of surface water for
				nonagricultural uses, the name of the water body utilized, the design capacity
				for the average daily and maximum daily withdrawal, and any limitation on
				withdrawals established by permits issued by the department, the Department of
				Health, or any other agency.
F. To
				the extent that information is available, a water plan shall include, for all
				self-supplied users of more than 300,000 gallons per month of ground water for
				nonagricultural uses, the name and identification number of the well or wells,
				the well depth, the casing depth, the screen depth (top and bottom) or water
				zones, the well diameter, the design capacity for the average daily and maximum
				daily withdrawal and any limitation on withdrawal established by permits issued
				by the department.
G. A water plan
				shall include the amount of ground or surface water to be purchased from water
				supply systems outside the geographic boundaries of the planning area on a
				maximum daily and average annual basis, any contractual limitations on the
				purchase of the water including but not limited to the term of any contract or
				agreement, the recipient(s) or areas served by the water purchased, and the
				name(s) of the supplier(s).
H. A
				plan shall include the amount of water available to be purchased outside the
				planning area from any source with the capacity to withdraw more than 300,000
				gallons per month of surface and ground water, reported on a maximum daily and
				average annual basis and any contractual limitations on the purchase of the
				water including but not limited to the term of any contract or agreement, the
				geographic region(s) that receive the water purchased, and the name(s) of the
				supplier(s).
I. A water plan shall
				include, to the extent possible, a list of agricultural users who utilize more
				than 300,000 gallons per month, an estimate of total agricultural usage by
				source, whether the use is irrigation or nonirrigation, and whether the source
				is surface or ground water.
J. A
				water plan shall include an estimate of the number of residences and businesses
				that are self-supplied by individual wells withdrawing less than 300,000
				gallons per month and an estimate of the population served by individual
				wells.
K. When available, a water
				plan shall include a summary of findings and recommendations from applicable
				source water assessment plans or wellhead protection programs.
