No, these are not the same thing. “Water” refers to operation of the drinking water system, including treatment, supply systems, and regulatory compliance (Safe Drinking Water Act).
“Wastewater” refers to the domestic sewer system, including sewage collection system, wastewater treatment plant operation, and regulatory compliance (Clean Water Act, the WRRF has an NPDES Wastewater Discharge Permit).
“Stormwater” refers to the operation of the storm drain system to convey and dispose of rainwater or snowmelt runoff, including the runoff collection, conveyance, outfall system, and local water ways. Stormwater is now being regulated like wastewater, which is why the City is under an NPDES Permit.
