Cities commonly measure parts of their water systems, yet data and responsibility are often divided among utilities, drainage districts, landowners, regulators, and watersheds that ignore municipal borders. Atlas begins with a stricter question: can precipitation, withdrawals, use, treatment, reuse, discharge, runoff, and aquifer change be reconciled on one public account? A settlement that cannot connect those flows governs only fragments of its watershed.
Every settlement can be read through two ledgers: the ledger of throughput — what is extracted, transformed, consumed, and discharged — and the ledger of return — what is safely reused, restored, repaired, or cycled back to soil, water, habitat, and the commons. One-way systems can move costs downstream and forward in time. Atlas therefore treats circularity as a hypothesis to measure, not a virtue to assume. The Water-Bearer's Codex, a companion project, develops the water side of this inquiry in full.
The deeper diagnosis comes from Fuller’s Critical Path: civilization’s physical capability can change faster than the institutions organizing it. The inherited question is often “Can we afford it?”; the critical-path question comes first: do the resources, energy, knowledge, sites, and organization physically exist, and under what constraints? That does not make every need already solved. It makes feasibility something to test against an inventory of reality before financial scarcity is accepted as the final verdict.
Atlas is a model for making those accounts visible. It treats a settlement as an interdependent organism — water flows as circulation, energy carriers and storage as metabolism, shells and foundations as structure, and a digital twin as a nervous system. The aim is to recover useful flows wherever doing so is safe and efficient. Treated discharge can remain necessary; the measurable target is to minimize avoidable loss without crossing public-health or ecological boundaries.
The project explores whether small, comprehensible micro-communities can become working centers of ecological research: watershed restoration, soil building, low-carbon shelter, resilient energy, food, and public learning. Atlas is proposed as one such prototype, born virtual so assumptions can be tested before any site is chosen. A physical version would require site selection, engineering, environmental review, public participation, permits, financing, and measured validation.
The epistemology is inherited. What Fuller pursued was a world that works for everyone, run on honest physical accounts: do ever more with ever less; make the whole visible through instruments such as the Geoscope and World Game; measure what exists; identify the true constraints; and act at the point of highest leverage before a crisis arrives. What Fresco pursued was the city as a serviced organism, with logistics coordinated across the whole and everyday needs placed close enough that distance and waste are not designed into daily life.
Atlas brings both ambitions to the water. Its concentric plan studies rings of function around a harbor core, with canals imagined as part of a broader mobility, stormwater, landscape, and thermal system. Potable water, non-potable reuse, navigable water, wastewater, and habitat are separate engineering and public-health problems; the exhibit connects their ledgers without pretending they are one interchangeable supply.
The hydraulic program deliberately separates established devices from proposals. Hydraulic ram pumps can trade part of a suitable source flow for lift; elevated reservoirs can store energy; electrolysis can convert surplus electricity into hydrogen, with substantial conversion losses and safety requirements. Civic-scale resonators, bored hydraulic works, compressed-granite storage, and other unconventional concepts remain experimental until calculations and prototypes establish their performance. The energy system is presented as a research program, not a finished plant.
The land is treated with the same whole-systems attention: agroforestry, food-forest belts, soil building, nutrient recovery, compact mobility, and habitat connectivity are studied together rather than added as decorative layers. The doctrine stays short: publish assumptions, keep units and boundaries visible, distinguish context from models and targets, test proposals, and revise them in public. Atlas does not claim a result before it has one; it builds the instrument by which a result could be judged.
