The applicant shall submit a water impact study when the proposed
use will exceed 10,000 or more gallons of water per day.
2.
A water impact study will enable the Township to evaluate the impact
of the proposed development on the ground water supply and on existing
wells. The purpose of the study will be to determine if there is an
adequate supply of water for the proposed use and to estimate the
impact of the new use on existing wells in the vicinity. The Township
Engineer shall be involved in the impact study as the Township feels
is appropriate and necessary. A water system which does not provide
an adequate supply of water for the proposed use, considering both
quantity and quality, or does not provide for adequate ground water
recharge considering the water withdrawn by the proposed use, or adversely
affects existing wells in the vicinity of the proposed development
shall not be approved by the Township. The adequacy of the water supply
for residential development shall be based upon the assumptions of
flows of 275 gallons per day per equivalent dwelling unit (EDU).
