(a) Residential water demand estimate. Residential
water demand estimates at full build out must be provided. Residential
demand estimates must, at a minimum, be based on the current demand
of any existing residential well including those identified under §230.8(b)
of this title (relating to Obtaining Site-Specific Groundwater Data),
or §290.41(c) of this title (relating to Rules and Regulations
for Public Water Systems), and:
(1) the number of proposed housing units at full build
out;
(2) the average number of persons per housing unit;
(3) the gallons of water required per person per day;
(4) the water demand per housing unit per year (acre
feet per year); and
(5) the total expected residential water demand per
year for the proposed subdivision (acre feet per year).
(b) Non-residential water demand estimate. Water demand
estimates at full build out must be provided for all non-residential
uses. Non-residential uses must be specified by type of use and groundwater
demand per year (acre feet per year) for each type of use. The estimate
must also include the existing non-residential demand of any well
including those identified under §230.8(b) of this title or §290.41(c)
of this title.
(c) Total annual water demand estimate. An estimate
of the total expected annual groundwater demand, including residential
and non-residential estimates at full build out (acre feet per year),
must be provided.
(d) Submission of information. The sources of information
used and calculations performed to determine the groundwater demand
estimates as required by this section must be made available to the
municipal or county authority if requested. The plat applicant must
provide any additional groundwater demand information required by
the municipal or county authority as part of the plat application.
