A feasible idea has to survive the full cost.

Cost per acre-foot can then reflect the resources actually attributable to producing and delivering water.

Cost allocation does not make capital costs disappear; financing and risk still have to be carried by someone.

This can change required peak capacity and operating cost even though total water production remains the same.

Water storage has its own capital, land, pumping and water-quality costs and cannot replace all grid flexibility.

Scenario analysis shows which assumptions actually drive feasibility.

A wide range is not a substitute for engineering; it identifies where better evidence is most valuable.

Feasibility means finding a design that meets water, reliability, economic and environmental requirements together.

Including mitigation costs does not establish that impacts are acceptable; project-specific environmental review is still required.

A transparent allocation makes it possible to test whether the project remains viable under different funding structures.

Potential revenue, public funding or industrial participation should not be counted until the terms and beneficiaries are defined.
