*IMPORTANT NOTE

If community and zone populations differ, then additional zones within this community are receiving water from plants that don't have this Priority 2 determinand assigned. Refer to the individual community structure page to see which zones are affected.

** Bulk water supplies, such as these, provide water to other communities instead of directly to people. Therefore, exclude them from any summation of populations so you don't count people twice.
(The statistics at the top of the page already exclude them.)
