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.

01 — Sources

Where the water comes from.

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.

  • No water rights or permitting
  • Works literally anywhere
  • Modular, redeployable footprint

Cons

  • Energy-intensive in dry climates
  • Lower throughput per cabinet
  • Output tracks humidity, not demand
Backup capacity, coastal & humid sites, off-grid bases.

$0.015–0.040 / L
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

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

$0.0004 / L
REMIN
CaMg
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

Anywhere domestic hot water is needed; resorts, residential, food & bev.
300–500 L tank
$0.0009 / L (vs. $0.0034 resistive)
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.

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

  • 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

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

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
