This is City of Mesa Water Resources’s own published figure, and it covers a whole system. Blending, season and your own plumbing all move it, so the number we size from is the one measured at your tap.
Where Mesa water comes from
Mesa draws on Salt River Project water, Central Arizona Project water and city groundwater wells, and splits the city into zones at the Eastern Canal. The groundwater share is what makes the Eastern and Southern Zones measurably harder than the City Zone to the west.
Installing in Mesa homes
Mesa is large enough to contain both extremes. Eastmark and Las Sendas are new enough to be loop-ready throughout. The mid-century core around Dobson Ranch and Alta Mesa, and Mesa’s substantial stock of manufactured and park homes, need a different approach — often a compact unit and a carefully placed drain.
