| (a) Residential water demand estimate. Residential water demand
estimates at full build out shall be provided as specified in §230.3(c)
of this title (relating to Certification of Groundwater Availability for Platting).
Residential demand estimates shall, 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 shall be provided for all non-residential uses as specified
in §230.3(c) of this title. Non-residential uses shall be specified by
type of use and groundwater demand per year (acre feet per year) for each
type of use. The estimate shall 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), shall be provided as specified
in §230.3(c) of this title.
(d) Submission of information. The sources of information used
and calculations performed to determine the groundwater demand estimates as
