The Catalog
The building blocks of your water grid.
Every Aquanode deployment composes from the same catalog of nodes — sources that pull water in, transforms that make it fit-for-purpose, storage that buffers and shifts it, and energy elements that power the whole grid. Each node has the same mesh interface. Pick the ones your site needs; add more as you grow.
Every site has at least one source. Most have two or three. The mesh treats them as a single pool of supply and routes from whichever is cheapest, freshest, or most available at any given hour.
6 nodes in this category
AWG
Atmospheric Water Generation
AWG
Condenses drinking-grade water out of ambient humidity. Modular cabinets that scale linearly — start with one, add more as demand grows.
Containerized seawater or brackish reverse-osmosis skid. The highest-throughput single-node option in the catalog when you're on a coast.
Pros
Massive throughput
Unlimited source (ocean)
Lowest $/L at scale
Cons
Needs coast or brackish access
Brine discharge permit required
Energy-dense without solar
Coastal industrial, hotels, data centers, municipalities.
8K L/day per skid
$0.0028 / L
WELL
Well / Groundwater
Well
Existing or new groundwater well, tied into the mesh through pressure and quality sensing. The foundational source on most rural and agricultural sites.
Pros
Lowest energy per liter
High, stable throughput
Already on most rural parcels
Cons
Aquifer-dependent
Drawdown risk under drought
Quality varies — RO often needed
Farms, rural residential, light industrial with existing well.
4K L/day per well
$0.0011 / L
UTILITY
Municipal tie-in
Utility
Local water utility, brought into the mesh as a sensed and metered input. Useful as a baseline or fallback, but priced and reliable at the utility's discretion.
Scheduled or on-demand tanker delivery from regional sources. The escape hatch when your other nodes are tapped out — or while permanent capacity is being installed.
Pros
Available within hours
No site capex
Bridges install lead times
Cons
Highest $/L by far
Logistics-dependent
Carbon-heavy vs. on-site nodes
Construction phases, emergencies, drought spikes, FEMA stockpile.
20K L per truck
$0.015–0.040 / L
01
02 — Transforms
Make every liter fit-for-purpose.
Source water rarely arrives ready to drink. Transforms take what the sources produce and change its chemistry, biology, or temperature until it matches what the end-use needs — potable, irrigation, hot service.
4 nodes in this category
RO
Reverse osmosis filtration
RO
Pressure-driven membrane that rejects salts, heavy metals, and most dissolved contaminants. The workhorse of the transform layer.
Pros
Reduces TDS by 95–99%
Removes lead, arsenic, PFAS
Modular, cartridge-replaceable
Cons
Generates 20–30% reject brine
Strips minerals — needs remin downstream
Membranes need periodic replacement
Downstream of well, desal, and utility sources for potable use.
6K L/day per skid
$0.0014 / L
UV
UV sterilization
UV
Inline ultraviolet lamp that inactivates bacteria, viruses, and protozoa as water flows past. The final biological polish before storage or use.
Pros
Kills 99.99% of pathogens
No chemical residuals
Low energy footprint
Cons
No effect on chemicals or metals
Lamps need annual replacement
Requires clear pre-filtered water
Final polish on AWG, well, RWC, and reused water before potable use.
Inline, per-flow
$0.0004 / L
REMIN
Remineralizer
Remineralization Stack
Adds back calcium, magnesium, and trace minerals that RO and distillation strip out. Restores taste and the small but real health benefits of mineral content.
Pros
Restores taste of stripped water
Calcium & magnesium intake
Corrosion-protects downstream pipe
Cons
Adds operating consumable cost
Media needs annual replacement
Useless without an RO upstream
Always pair with RO when output is for human consumption.
Inline, per-flow
$0.0006 / L
HEATPUMP
Heat pump water heater
Heat Pump + Water Heater
Moves heat from ambient air into water using a refrigeration cycle — 3–4× more efficient than resistive heating, and the cheapest way to make hot water from solar.
Pros
3–4× efficiency vs. resistive
Pairs perfectly with solar
Doubles as building dehumidifier
Cons
Higher upfront cost
Slower recovery in cold weather
Needs ambient air volume
Anywhere domestic hot water is needed; resorts, residential, food & bev.
300–500 L tank
$0.0009 / L (vs. $0.0034 resistive)
02
03 — Storage
Buffer in time.
Production and demand never match minute-to-minute. Storage is what lets the mesh produce when energy is cheap and water is abundant, then deliver when neither is true. The simplest node in the catalog — and quietly the most important.
2 nodes in this category
TANK
Water tank
Tank
Sealed, food-grade storage tank with level, temperature, and pressure sensing on the mesh. Sized to your site's daily peak factor and seasonal volatility.
Pros
Decouples production from demand
Survives short outages cleanly
Cheapest node per stored liter
Cons
Real footprint cost
Requires periodic sanitation
Stagnation risk if oversized
Every site needs at least one. Bigger sites need 2–4× peak-day capacity.
5K – 200K L per tank
Effectively zero
WELLRETURN
Aquifer recharge
Return to Well
Routes surplus produced water back into your well casing or a dedicated injection point, turning the local aquifer into a multi-million-liter natural battery. When demand spikes or surface storage runs dry, the same well pulls it back out — already filtered by the ground it traveled through.
Pros
Effectively unlimited storage volume
No tank footprint above grade
Natural backup during outages or drought
Cons
Permitting varies by jurisdiction
Recovery rates depend on local geology
Water quality must meet recharge standards
Sites with an existing well and seasonal production surplus — convert overproduction into a passive reserve instead of dumping it.
Aquifer-bound · typ. 100K+ L recoverable
Pump energy only

04 — Energy
Power the whole grid.
Water without energy is gravel. Every node in the catalog draws electrons; the mix you choose between solar, battery, and grid is the single biggest lever on your $/L. The intelligence layer decides where the next watt comes from at any given second.
3 nodes in this category
SOLAR

PV
Photovoltaic panels sized to the site's combined water+building load. Cheapest electron ever produced; the foundation of any low-$/L deployment.
Pros
$0.02/kWh LCOE — and falling
Predictable 25-year output
Zero marginal cost once installed
Cons
Intermittent — needs storage
Real roof or land footprint
Seasonal & weather-dependent
Every site that isn't in a permanent shadow.
5 kW per array
≈ $0.02 / kWh
BATTERY
Battery storage
BESS
Lithium-iron-phosphate storage on the mesh, used to time-shift cheap solar into expensive peak hours and to ride through brief grid disturbances.
Pros
Time-shifts cheap solar to peaks
Sub-second grid disturbance ride-through
Costs falling ~15% per year
Cons
Adds capex up front
Cycle life is finite
Footprint and fire-suppression spec
Anywhere solar exists and grid prices vary by hour.

Grid
Connection to the local electrical utility, used as the fallback supply when solar+battery isn't covering load. Bidirectional where net-metering rules permit.
Pros
Always-on backstop
Net-meter revenue when allowed
Zero capex (just interconnect)
Cons
Retail rates 5–10× solar LCOE
Peak-hour pricing punishes you
Outages outside your control
Backstop for every grid-connected site; primary only when solar isn't viable.
Site-dependent
Market rate · $0.10–0.30 / kWh

How nodes compose
Source → Transform → Store. Energy underwrites all of it.
The mesh routes liters from the cheapest available source, through whatever transforms a use-case demands, into the storage layer that buffers peak demand and bridges supply gaps. Energy nodes — solar, battery, grid — are the lever the intelligence layer pulls on to keep $/L low.
Source · brings water in
Transform · changes properties
Storage · buffers in time
Energy · powers the grid
