Finding 04 Counted through feedback

How Much Water Did Great Pyramid Workers Need Each Day?

3.39 million liters of water daily

The workers would have needed more than drinking water. Food preparation, village use, and the construction processes in the modeled scenario bring the total to 3.39 million liters delivered each day.

Counted through feedback. Water is not one of the five independent failures. It is counted through feedback: the people who carry the water, and their households, need water too, so the model adds them to the workforce and population the other findings test.

What the audit found

Water delivery reaches approximately 3.39 million liters per day. The initial calculation requires 1,471 active adult carriers. Once the water consumed by the carriers and their households is included, the requirement rises to 19,960. Of those carriers, 18,489 are created by the feedback itself.

In the published model, delivering that water would have taken 19,960 adults actively carrying it, with 34,695 people in the full workforce needed to keep those jobs staffed. Those carriers would also have needed water and support. The calculation counts their needs too.

How the water figure is built

  1. Daily demand

    Drinking, food preparation, village use and construction processes: about 3.39 million liters delivered to Giza a day.

  2. Carriers before feedback

    Before the feedback is counted, the calculation needs 1,471 active adult carriers.

  3. The feedback loop

    Carriers and their households need water too. Solving the loop raises the count to 19,960; 18,489 of them exist only because of the loop.

  4. The rostered workforce

    Keeping those carrying jobs staffed takes 34,695 people in the full workforce.

What would change it

An alternative delivery system could reduce that labor, but only after its construction, operation, maintenance, materials, and support requirements are defined and counted.

Inputs and how they are treated

InputValueTreatment
Domestic and process water, including loss2,964,662 L a dayThe volume remains required even if the delivery method changes.
Youth light-support credit5%A bounded allowance for older children helping with light village water tasks at times. It lowers adult carrying, not the water volume.
Wells, canals, cisterns, animals or boatsnot assumedAllowed, but only once each carries its own labor, material, maintenance, feedback and evidence burden.

Limits of the finding

These population totals include dependents who existed independently of the project, so they do not replace the governing non-farm labor test. They show the scale of the population that must be provisioned for the construction program to operate.

A canal, well, storage tank, animal team, or boat does not deliver water simply by being named. A proposed replacement must show where the water would have gone, how much it could have delivered each day, and what it would have taken to build, operate, and maintain.
