•Evaluating your Master Plan– Check all the areas zoned residential
(self-supplied) or Commercial/Industrial (self-supplied) to determine which catchments they fall within.
– “Roads” and “Aerial Photos” Data Layers in WWAT are very useful spatial references.
– Use “New Withdrawal” in WWAT to determine the total allowable depletion in those catchments.

•So how many gpm do you need?– A standard residence needs a minimum of 20
gpm (~ 60 gpm with home irrigation).
– For clustered developments (e.g., PUDs), multiply the # of parcels times 20 gpm to estimate the cumulative depletion.
e.g. 15 parcels x 20 gpm/parcel = 300 gpm
– Note: residential water well withdrawals are NOT regulated by state law. Consider re-arranging the zoning map to mitigate potential adverse impacts.

•So how many gpm do you need?– Commercial/industrial user needs vary
widely. Some water-intensive businesses may need 600 – 1000 gpm.
– PA 33 (2006) prohibits a local unit of government from enacting or enforcing an ordinance that regulates a large quantity withdrawal (i.e., 70 gpm or more).
– The evaluation suggested here is with the intent of re-arranging the zoning map to mitigate potential adverse impacts.

•Revise your Site Plan Review process– Amend your site plan review checklist to
require submission of applicable LQW Registration with the site plan for any self-supplied facility with a pumping capacity of 70 gpm or more (e.g., within “Other Environmental Impacts” section).

•Economic Development Office– Check all parcels slated for new/expanded
Commercial/Industrial (self-supplied) to determine which catchments they fall within.
– Use “New Withdrawal” in WWAT to determine the total allowable depletion in those catchments.
– Compare allowable depletions to client’s needs.
