Illinois Administrative Code › Title 17 - CONSERVATION › Part 3730 - ALLOCATION OF WATER FROM LAKE MICHIGAN › Subpart C - ALLOCATION RULES › Section 3730.307 - Conservation Practices and Other Permit Conditions

Current through Register Vol. 48, No. 28, July 12, 2024
a) The Department shall condition allocations
				within a user category upon required conservation practices for each user
				category as specified in subsections (b) and (c). Failure by any permittee to
				meet the conservation requirements applicable to it within a reasonable period
				of time will, upon notice, hearing and determination of the failure,
				constitutes a violation of a Department order.
b) Permittees in Categories IA and IB shall
				limit non-revenue water so that it is less than 12% of net annual pumpage
				(system input volume) in Water Year 2015, decreasing to no more than 10% by
				Water Year 2019 and all years thereafter. Permittees whose non-revenue water
				exceeds the non-revenue thresholds (12% in Water Year 2015, decreasing to 10%
				by Water Year 2019) shall submit a water system improvement plan that outlines
				the actions the permittee 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 requirements to submit a water system
				improvement plan to a permittee 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 recognizes that actions
				necessary to reduce water losses can require significant capital expenditures
				and a lengthy timeframe, and that communities face other pressing
				infrastructure needs, and will take this into account in reviewing and
				approving water system improvement plans.
c) The Department shall require evidence of
				adoptions by the permittee of the following conservation practices as
				applicable to the particular user:
1) Leakage
				monitoring and correction for storage, transmission and distribution
				systems.
2) Metering of all new
				construction. When practicable and feasible, the Department recommends
				sub-metering in new multi-family buildings.
3) Metering of existing non-metered services
				as part of any major remodeling.
4)
				The adoption of ordinances requiring that new and replacement plumbing fixtures
				be a labeled WaterSense product, as specified by USEPA.
5) The adoption of ordinances requiring the
				installation of closed system air conditioning in all new construction and in
				all remodeling.
6) The adoption of
				ordinances requiring that all lavatories for public use in new construction or
				remodeling be equipped with metering or self-closing faucets.
7) The adoption of ordinances requiring that
				all newly constructed or remodeled car wash installations be equipped with a
				water recycling system.
8) The
				adoption of ordinances that restrict non-essential outside water uses to
				prevent excessive, wasteful use. These shall provide that unrestricted lawn
				sprinkling will not be allowed from May 15 through September 15 of each year by
				requiring, as a minimum, that lawn sprinkling shall not occur on consecutive
				days nor shall any lawn sprinkling occur during at least a 6 hour period in the
				middle of the day (i.e., 10 a.m. through 4 p.m., noon to 6 p.m.) when
				evapotranspiration is at its highest. New lawns (less than 3 months old) may be
				exempted from this provision. In addition, new/replacement sprinkler systems
				shall be equipped with a WaterSense labeled irrigation controller and shall be
				in compliance with Section 2.5(g) of the Illinois Plumbing License Law [225
				ILCS 320 ].
9) Development and
				implementation of public programs to encourage efficient water use.
10) Installation of facilities and
				implementation of programs to reduce to a reasonable minimum, and to accurately
				account for, water used for navigational and discretionary diversion
				purposes.
