Industry agent: Water utilities and data centres
Run the data centre water market on governed AI.The AI software platform for recycled water that data centres run on.
Data centres need cooling water, and where they cluster the pipes are already full at peak. Drinking water is the wrong thing to cool with. A licensed precinct can supply recycled water instead, and its members can trade what they hold. Hydrabyte Exchange runs that market: the register, the trades, the meters, the settlement, and the reports the regulator reads.
For water utilities, recycled-water precinct operators, data centre and industrial water users, and the regulators who license them.
The demo is open to registered visitors with an organisation email. Each request is approved individually. It runs on fictional data.
The economic problem
Laid bare: the water is there, the market is not
Data centres need water they cannot get, utilities have capacity they cannot price, recycled-water plants have demand nobody will contract, and households carry the risk. Each party is stuck for a reason the others could fix. Sydney is the worked example; the same stalemate is forming in every city where data centres cluster.
Data centres cannot connect
A single site can ask a utility for 5 to 40 megalitres a day. Where the supply zone is already full, there is no connection to give, however much the operator is prepared to pay.

Housing competes for the same pipe
In Sydney, the supply zone serving Macquarie Park's data centre cluster is at full capacity, and the council has warned that clustering is straining the infrastructure homes depend on.

The peak is paid for by everyone
New capacity is built for the peak, and unless charges reflect peak demand rather than average use, every customer pays for augmentation a few large users drive. That is the question the NSW regulator is now examining.

Drinking water goes to cooling
Data centres are under 1% of Greater Sydney's demand today, about 3.5 billion litres a year, and could add 20 to 25% to total demand by 2035; one estimate puts cumulative Sydney demand at 250 megalitres a day if proposed sites use water-intensive cooling.

Recycled-water plants do not get financed
A recycled-water plant needs contracted, creditworthy demand before anyone will fund it. Without an offtake market there is no bankable demand, so the plant that would solve the problem is never built.

Nobody can see who uses what
Planners lack reliable demand data at the approval stage. Policy now points to smart meters at every data centre site and better demand data, but the meters alone do not create a market.

What trading recycled water changes
Contracted offtake makes the plant bankable, so it gets built. Trading moves scarce capacity to whoever values it most and puts spare volume back to work instead of leaving it idle. Metering settles who used what, so the peak is paid for by those who drive it. A reserve set before any right is issued keeps drinking water and housing capacity out of the market altogether. One register, read by everyone, turns a dispute about who pays into a record of who did.
The main benefit, stakeholder by stakeholder
Everyone gets the one thing they are missing today
Data centres
Water certainty to build and grow, and a way to show they are not taking drinking water.
Water utilities
Growth that pays its way, and the demand data to plan for it.
Recycled-water operators and investors
Bankable, long-term demand that finances new plants.
State government and regulators
Data centre investment without trading off housing or water security.
Community, households and housing
Drinking water and housing capacity protected as data centres grow.
Environment and water security
More reuse and less draw on drinking-water supply.

The operating model
A licensed precinct, a private market
A precinct operator holds the licence, builds and runs the recycled-water plant, and sells its output under long-term take-or-pay offtake to data centres and other industrial users. Those contracts are the anchor: they underwrite the plant and they are what the members then trade. Government licenses and inspects the operator. It does not run the market, and it does not have to legislate one.
Who runs the market
- The precinct operator: licence, plant, offtake contracts, curtailment and settlement
- The exchange and registry: contracted volumes recorded; swaps, leases and tiers traded
- The public utility: sewage access, potable fallback, the smart-meter feed
Who licenses and inspects
- The economic regulator licenses the private utility and monitors compliance
- The health regulator sets water-quality limits the operator reports against
- The competition regulator watches for market power among a few large buyers
Who participates
- Data centres as foundation customers on long-term take-or-pay offtake
- Other industrial users buying surplus, which smooths the plant's demand
- Investors funding the plant against the contracted revenue on the register
Why this model first
How the market runs
Six steps, every month, on one evidence chain
Every state-changing action writes one entry to an append-only, hash-chained audit trail. Each entry's hash covers the one before it, so an edit or a deletion breaks the chain, and the chain is verified live on the dashboard, on the audit page and inside every regulator report.
Register
The precinct network with the plant's output as its capacity and a reserve held back for amenity and turndown, set before any right is issued. Contracted offtake, interruptible tiers and verified offsets recorded as rights, each with a provenance.
Market
A continuous order book with price-time priority. Transfers are permanent; leases run for a term and revert. Offers are limited to unencumbered holdings and a holding limit stops hoarding. No forwards, options or other derivatives.
Meter
One smart-meter reading per site per day, read against each holder's entitlement as the month runs.
Curtail
Drought stages from a rules table, applied by tier, interruptible supply first and firm supply last. The regulator can read what each stage does before it is ever declared.
Settle
Entitlement computed day by day from the register against metered use. Over-use charged at the market's rate; use below the floor flagged for review, not charged.
Report
A snapshot for the regulator and the members with every figure and its source: capacity and reserve, use against entitlement, trades, curtailment, water quality and the state of the audit chain.
Trading agents
Agents prepare. People decide. Every time.
Each member can run a trading agent. The agent does the watching and the arithmetic: it projects need from metered use, compares it with deliverable entitlement after curtailment, reads the resting book and the drought stage, and prepares the order it would place, with its reasons.
A person keeps the decision. That rule is enforced in code and evidenced on the chain, not written in a policy.
- A mandate per member: buffer above projected need, price ceilings and floors, largest order, allowed products, lease preference, and the value below which the agent may act alone.
- Three strategies: close a shortfall, lease out a surplus before it trips the use-it-or-lose-it floor, and seek firm cover when a drought stage curtails supply.
- Every proposal carries the order, a plain-English rationale with the numbers, and the signals it used, stored as data. The engine is deterministic, so any proposal can be reproduced.
- Small orders inside the mandate execute through the same checks as a hand-placed order. Everything else waits in a decision queue for a person to approve or reject.
- A kill switch for the market, a pause for any one agent, and every run, proposal and decision on the hash-chained audit trail.
What is traded
Three products, each a right with a provenance
Recycled-water offtake
Long-term rights to the plant's output: cooling water that spares drinking water. Transferred outright or leased for a term.
Interruptible tiers
Cheaper supply curtailed first in drought, backed by on-site storage and night-time filling.
Offsets and credits
Capacity earned by funding verified savings elsewhere, such as leak repair or stormwater harvesting, recorded by the operator as verified.
Who it is for
What each party gets from the same register
Precinct operators
A register that records every offtake contract, tier and condition, a market that keeps members trading inside the plant's output, settlement that charges over-use and flags under-use, and the reporting a licence demands, produced as the work happens.
Recycled-water investors
Contracted, metered demand from creditworthy members recorded as bankable evidence, and a market for surplus that improves plant use.
Data centres and industrial users
Water certainty to build and grow on recycled supply, a way to show they are not taking drinking water, a market to swap spare volume, lease peak capacity and buy interruptible supply, and an agent that watches the position for them.
Utilities, regulators and the community
Cooling demand moved off the potable network, sewage access terms on the register, metered data for planning, a licensing regulator who can read everything, and an audit chain anyone can verify.
How it is sold
Standard rails. Made-to-measure services.
The market operator subscribes to the platform: registry, trading engine, metering, settlement, curtailment and reporting. Each member pays for a seat with trading access, its agent, portfolio views and its own audit-ready water-use, source and offset reporting. A small fee on each trade tops that up; it never carries the business, because a precinct has few members and trades rarely.
Each jurisdiction's licence conditions, curtailment rules and utility interfaces are a fixed-scope build, sold alongside the subscription, never instead of it. The custom share is kept small by design and measured on every build. No made-to-measure build without the platform underneath it.
What we claim, and what we do not
- Hydrabyte Exchange is a concept platform. The demonstration runs on a fictional precinct with invented organisations, prices and readings, and nothing is deployed for a customer.
- Arrochar Labs provides the platform. It never trades, never holds water rights and never builds plants: a market operator that also traded would have a conflict, and the platform is built so it cannot.
- No forwards, options or other derivative-style contracts are offered. Whether any product is a financial product is a question for legal advice before a pilot, not a claim on this page.
- A precinct market cannot trade capacity in the public network. That is not private property, so only the utility and the regulator can create rights over it. The platform enforces that rule by configuration, and the public utility stays the supplier of last resort.
