Illinois Administrative Code › Title 17 - CONSERVATION › Part 3730 - ALLOCATION OF WATER FROM LAKE MICHIGAN › Subpart C - ALLOCATION RULES › Section 3730.304 - Water Needs Criteria

Current through Register Vol. 48, No. 28, July 12, 2024
The Department will determine anticipated water needs for
				  each applicant. The Department will take into consideration in making that
				  determination the population of the area to be served, projected population
				  growth, current and projected per capita consumption within the area, the
				  nature and extent of industrial uses (including a consideration of typical
				  requirements for similar industries), municipal and hydrant uses (public
				  facilities, park upkeep, fire protection), implementation of conservation
				  practices, and the reduction of non-revenue water as required by this
				  Section.
a) Conservation practices
				that will be considered with respect to applicants in Categories IA and IB
				include the extent of metering, the provision of building codes for water
				efficient equipment, ordinances that promote the efficient use of water for
				lawn sprinkling and other outside uses, rate structures that encourage
				conservation, past record of enforcement of water saving ordinances,
				expenditures for maintenance and repair of water distribution systems, and
				implementation of specific ground water conservation levels of usage
				recommended by State or regional planning agencies. The Director may establish
				maximum reasonable per capita consumption rates for each user based upon either
				an evaluation of the relative proportion of industrial, commercial and
				residential users served by the permittee or the efficiency of the permittee's
				water distribution system, or both. Applicants in Categories IA and IB shall
				limit non-revenue water so that it is less than 12% of net annual pumpage in
				Water Year 2015, decreasing to no more than 10% by Water Year 2019 and all
				years thereafter. Applicants whose non-revenue water exceeds the non-revenue
				thresholds (12% in Water Year 2015, decreasing to 10% in Water Year 2019) shall
				submit a water system improvement plan that outlines the actions the applicant
				plans to undertake, along with a timeframe, to reduce non-revenue water to less
				than the thresholds outlined in this subsection. The Department may grant a
				waiver to the requirement to submit a water system improvement plan to an
				applicant whose non-revenue water exceeds the thresholds if it can be shown
				that the reason for exceeding the non-revenue water threshold is due to
				metered, but unbilled, consumption or to authorized, unmetered, unbilled
				consumption when the quantity can be determined through acceptable engineering
				practices. The Department will consider this information in determining proper
				allocation amounts.
b) Conservation
				practices that will be considered with respect to applicants in Categories IIA
				and IIB include improved and more accurate measurement and accounting
				procedures, improved treatment of all wastewater flows, elimination of
				untreated combined sewer bypass flows, reasonable use of aeration facilities,
				implementation of navigational and storm response operations, and procedures to
				minimize Lake Michigan diversion and implementation of effective programs of
				leak prevention, detection and correction.
