| (a) RWPs shall present projected population and Water
Demands by WUG as defined in §357.10 of this title (relating
to Definitions and Acronyms). If a WUG lies in one or more counties
or RWPA or river basins, data shall be reported for each river basin,
RWPA, and county split.
(b) RWPs shall present projected Water Demands associated
with MWPs by category of water use, including municipal, manufacturing,
irrigation, steam electric power generation, mining, and livestock
for the RWPA.
(c) RWPs shall evaluate the current contractual obligations
of WUGs and WWPs to supply water in addition to any demands projected
for the WUG or WWP. Information regarding obligations to supply water
to other users must also be incorporated into the water supply analysis
in §357.32 of this title (relating to Water Supply Analysis)
in order to determine net existing water supplies available for each
WUG's own use. The evaluation of contractual obligations under this
subsection is limited to determining the amount of water secured by
the contract and the duration of the contract.
(d) Municipal demands shall be adjusted to reflect
water savings due to plumbing fixture requirements identified in the
Texas Health and Safety Code, Chapter 372. RWPGs shall report how
changes in plumbing fixtures would affect projected municipal Water
Demands using projections with plumbing code savings provided by the
Board or by methods approved by the EA.
(e) Source of population and Water Demands. In developing
RWPs, RWPGs shall use:
(1) Population and Water Demand projections developed
by the EA that shall be contained in the next State Water Plan and
adopted by the Board after consultation with the RWPGs, Commission,
Texas Department of Agriculture, and the Texas Parks and Wildlife
Department.
(2) RWPGs may request revisions of Board adopted population
or Water Demand projections if the request demonstrates that population
or Water Demand projections no longer represents a reasonable estimate
of anticipated conditions based on changed conditions and or new information.
Before requesting a revision to population and Water Demand projections,
the RWPG shall discuss the proposed revisions at a public meeting
for which notice has been posted in accordance with §357.21(g)(2)
of this title (relating to Notice and Public Participation). The RWPG
shall summarize public comments received on the proposed request for
projection revisions. The EA shall consult with the requesting RWPG
and respond to their request within 45 days after receipt of a request
from an RWPG for revision of population or Water Demand projections.
(f) Population and Water Demand projections shall be
presented for each Planning Decade for WUGs in accordance with subsection
(a) of this section and MWPs in accordance with subsection (b) of
this section.
