Entity Name: SWP Intake Protection Zone
Table Name: SWP_INTAKE_PROTECTION_ZONE_FT
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. IPZ-1: FIRST ZONE around intake, very vulnerable to contamination. Direct and immediate impacts are possible as there is no time to take mitigating action.IPZ-2: SECOND ZONE around the intake where direct impacts are possible because contaminants may reach intake within 2 hours. IPZ-3: THIRD ZONE and the 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.
