CLOSPA Intake Protection Zone (IPZ) 3

Click to view Metadata The area around an intake pipe in a lake or river that draws in the surface water used to supply the municipal drinking water system. Three zones, from the closest to the farthest from the intake, rate the vulnerability threat. The IPZ-3 is the THIRD ZONE and largest zone around the intake where activities can impact the source water, but there is time to take action to ensure the intake and municipal water is not impacted. NOTE: A null value in the Intake Identifier (Intake_ID) indicates that IPZ-3 feature is associated with more than 1 intake. For additional information on these one-to-many relationships, please refer to Assessment Report Chapter 5 - Spill Scenario Mapping.
